How to paint a slate roof and how. Slate painting. How and with what to paint slate? Quick dry slate enamel

Many roofs of buildings and structures are covered with slate. Currently, this roofing material has many competitors, but slate has its own niche in the construction market. New roofing materials look much more attractive, primarily due to their bright colors. However, this advantage can be easily offset by painting the slate roof. At the same time, it is possible to extend the life of the roofing material. But not every paint is suitable for this procedure. So what is the best way to paint slate? What paint and varnish products are intended for these purposes, and how to properly apply it to the surface of the slate?

profiled sheets;
roof panels;
flat slabs.

The coloring of slate sheets having a wavy shape is carried out with acrylic paints designed specifically for this roofing material. At the same time, they increase decorative qualities roofing, and also significantly increases its service life. Weatherproof acrylic paint forms a durable protective layer that improves the performance of the material, namely:

protects sheets from destruction;
increases their frost resistance;
reduces the degree of water absorption;
reduces the amount of asbestos released into the environment;
increases the service life of slate sheets by 1.5-2 times;
prevents the growth of mosses and lichens.

If for any reason on separate area the paint layer is broken, then restoration work is carried out immediately, without waiting for the next general repainting of the roof. After all, slate, being a porous material, quickly becomes contaminated under the influence of atmospheric precipitation and acquires a very unsightly appearance.

Paint and primer for slate: Shikril

Among the special paints and varnishes produced to protect slate is Shikril acrylic paint, which is based on organic solvents. This paint is used to finish not only asbestos-cement slate, but also concrete plinths, cement-sand tiles and others external surfaces requiring alkali-resistant staining.

With the help of paint Shikril update damaged areas previously painted surfaces in need of urgent repair. The basic range of colors includes:

white;
gray RAL 7040;
burgundy RAL 3011;
brown RAL 3009;

Today it is used both in unpainted (for cottages, for outbuildings and non-residential premises), as well as in colored form. Last option can give the house additional aesthetics. However, deciding to transform the roof of the house, you should choose the right materials. Let's try to figure out how to paint slate, which paint is preferable and why?

Let's start with the fact that most of our compatriots are firmly convinced that only wavy sheets are "slate", but in fact, flat sheets of asbestos-cement chips also fall under this definition.

What is the best paint for slate?

Modern Choice materials is huge, and this makes it possible to make the roof of the house truly individual. When choosing how to paint slate, evaluate all the advantages and disadvantages of imported and domestic options, and only then make a purchase.

Acrylic paint for slate

The list of indisputable advantages of acrylic or water-dispersion compositions includes:

§ Ability to fill small cracks and reliable protection against moisture penetration.

§ Hydrophobicity. Water rolls easily over the painted surface, which makes it possible to work with the composition on flatter roofs.

§ Reducing the load on the rafters. Occurs by improving the conditions for snow to melt from the slate.

§ It is possible to work with acrylic paint at air temperature from +5°С to +35°С. The drying process takes 1-2 hours, the complete polymerization of the composition takes a day.

If you are looking for how to paint flat slate? For these purposes, acrylic paint is best suited. It provides the roof with maximum resistance to weathering and temperature extremes.

Quick dry slate enamel

This option contains a binder that promotes the formation of a smooth film on the roof surface. The roof, painted with such enamel, is not only durable, but also has high water-repellent properties, is reliably protected from the damaging effects of ultraviolet rays.

Liquid plastic for slate

This synthetic composition is made on a polystyrene, bitumen or vinyl chloride basis. The high popularity of such paint for slate is explained by the convenience of its application, as well as high elasticity, which eliminates the risk of delamination of the coating. Rubber paint contains pigments that keep the color from losing its brightness for a long time. The only downside is toxicity. The composition should be applied in special respiratory and hand protection.

§ Dachbeschichtung (Germany). It is known for its durability, strength, high adhesive properties. But at the same time it is more expensive than other imported analogues and can only be applied to natural tiles, slate.

§ Polifarb/Akrofarb (Poland). This composition is created on the basis of dispersion paints, which ensures a high drying speed, as well as color saturation and brightness.

§ Kilpi (Finland). This paint is perfect for slate, corrugated board, metal tiles.

§ Eter Akva (Finland-Sweden). This material is resistant to alkaline aggressive environments, is water-soluble, contains acrylate. It is used for staining slate and concrete.
How to repair and paint slate

Old slate can last for quite a long time if appropriate measures are taken to this. Of course, this requires a lot of work, but it is still much cheaper, easier and faster than replacing the entire roofing material.

The slate can be restored. To do this, it needs to be washed, repaired and painted.

The first step is not as easy as it seems. Rags and sponges will be useless here. And even with hard metal brushes to clean old slate, which for long years covered with a layer of moss, it will be impossible. Here it is better to use something more serious. In particular, we can recommend a nozzle for a drill in the form of a round stiff brush. Using this nozzle, it is quite possible to clean the slate to a state suitable for further work.

But a high pressure washer will be even more effective. This tool is used in construction. Also, it can often be seen at car owners and in car repair shops. Of course, it is better to use a construction sink, as it has more power.

It is impossible to skip the stage of cleaning the old slate. The fact is that the materials that will be further used for its repair and subsequent protection should not be applied to the layer of debris. In this case, they simply will not be able to properly adhere to the surface and will peel off after a few days.

Old slate often has nasty cracks. It was difficult to deal with them before. But today, new materials have appeared on sale that simplify the task many times over. These materials include bituminous two-component mastics.

If the task is not to urgently repair the slate to eliminate the leak, but you want to really improve the quality of the old coating, renew it and extend its service life, then you should not buy and use ready-made mastics. It is better to use two-component ones, which are mixed in a suitable container before use and only then applied to the roof.

Mastics are different and in order to perform the work on repairing slate with their help in a quality manner, it is necessary to read the instructions that are attached to them and, most importantly, follow all the recommendations that are set out in it.

After the slate is free from cracks, it is primed. Choosing primers for slate is not easy, as slate is made from a complex composition that may not be compatible with the primer. In order not to risk, you can buy an acrylate primer, which is better than others for slate and other similar materials.

You can also prime the slate with paint. To do this, you just need to dilute the paint clean drinking water in a ratio of one to ten.
As for painting slate, it is recommended rubber paint. It is plastic, easily adapts to any conditions, durable and strong. Such paint will become a reliable protection for the roof and significantly extend the life of the slate.

Paints for slate of domestic production:

§ Butanite (Russia). The composition contains polymeric substances and mineral-silicic additives. Butanite provides the roof with reliable protection against atmospheric action, increases the frost resistance of the surface.

§ Polifan (Russia). The paint is suitable for work on slate, concrete, brick. Its indisputable advantages include durability, color fastness, wear resistance.

§ Unisal (Belgorod). The composition contains acrylic elements and coloring pigments. High Quality. This ink provides a coating that is resistant to UV exposure and the damaging effects of moisture.

If an already installed roof is to be processed, preparatory measures will be required. To do this, you should prepare a brush with metal hairs, a grinder or a drill with a specially brushed nozzle, or a high-pressure car wash. The latter option will make the process less time consuming and highly efficient.

Using the above tools, we clean the roof from plaque, moss, etc. Next, we treat the surface with an antiseptic, which will prevent the reproduction of fungi and the appearance of plaque. The next step is the primer.

Having carefully primed the slate sheets, you can be sure of the maximum adhesion of the paint to the surface of the roofing material. In addition, the primer, filling the pores, will significantly save the paint itself, and the roof surface will become more even.

Surface painting is best done in 2 layers. The composition can be applied with a roller or brush or spray. It is not recommended to paint slate in rainy weather and very hot days

Before painting directly, the slate must be checked for hidden serious damage by careful inspection. If some sheets are cracked, they must be replaced. Simultaneously with checking the condition of the surface of the slate sheets, the reliability of their fastening and, if necessary, additional strengthening are also checked. Then the most time-consuming procedure is performed - cleaning and grinding the entire surface, which completely removes dirt and dark patina. This work is done using an electric drill with a grinding attachment. Additionally, it would be nice to rinse the slate with a powerful jet of water from an electric washer.

After cleaning, you must immediately cover the surface with a special antifungal primer, after which a liquid cement mortar (in the consistency of kefir) is applied to the roof. The solution must be applied with a brush (a roller is not suitable for this operation). After waiting for the solution to harden, the surface of the slate is primed again. The pores and microcracks are sealed and the process of applying paint can begin.

The choice of paint for slate

The selection of paint is carried out taking into account what result you want to achieve - a bright appearance with slightly worse durability indicators, or vice versa, excellent performance with calm and discreet tones. In the first case, acrylic enamel is used, in the second, rubber paint, or, as it is also called, liquid plastic. Both options have advantages and disadvantages.
Acrylic paint for slate

Acrylic enamel has a water base and fills microcracks well, protecting the slate from destruction. It also has water-repellent properties, which is important, since rain, unfortunately, is not a rare occurrence in our latitudes and its detrimental effect on the roof surface is most sensitive.

When choosing acrylic paint for slate, you must carefully read the annotation, as it indicates the conditions for its use and lists the surfaces where it should be applied.

Rubber paint for slate

Many experts recommend rubber paint for slate, as a special composition that creates an elastic protective film on the surface, which prevents peeling of the paint. It is also good because it adheres well to slate and is easy to apply.

The rubber paint for slate includes special pigments that do not allow color shades fade in the sun, so there will be no dull gray color of the roof. A serious disadvantage of rubber paint is its toxicity, so the protection of the respiratory system and exposed skin during painting should be given increased attention.
Paint for slate Condor

Weather-resistant acrylic paints for slate Condor (KONDOR), produced in Belarus under a German license and having excellent performance as well as good value for money. Condor paints are sold in all building hypermarkets and many stores for summer residents.
Slate painting

So, the roof is prepared, the paint is selected, you can start painting the slate. And here arises important question: is it possible to paint slate in damp and damp weather, will it damage the quality of work? Hurt! Better paint job produce in dry and warm weather.

Reviews of those who painted slate themselves say that work done on a warm spring day gives the best results and the paint lasts longer after spring application than if it is done in a hot summer. For painting, a roller, brush or spray is used, the paint is applied in two layers, with the first one having completely dried beforehand.

If all operations are performed correctly, the old-new slate roof will last a very long time. long time, and the paint will retain color and will not crumble even after intense precipitation and temperature changes
Slate preparation

The process of preparing the slate is to clean it from any debris. It should be noted that this procedure often requires even new material, since it may contain adhering particles of asbestos cement, which are invisible at first glance. To remove them, you can use the usual small spatula.

Advice! Before you paint the slate fence, you should break through the grass, which usually grows along it and interferes with painting.

If the slate has already been used, then it is necessary to clean it more carefully. To do this, use a hard metal brush, processing every centimeter of the surface.

Slate cleaning field, it should be wiped with a damp cloth to remove dust and small debris.
Padding

The next step is priming. For these purposes, it is best to use an acrylic universal primer.

The instructions for applying it look like this:

1. first of all, the canister with soil must be thoroughly shaken;

2. then the liquid must be poured into a container into which it will be convenient to dip the brush;

3. Next, you need to moisten the paint brush in the ground, slightly squeeze it against the walls of the container and then apply the liquid to the surface of the slate. The soil must be even thin layer, so it is necessary to avoid streaks and large accumulations of liquid in certain areas.

If you plan to paint flat slate, you can use a paint roller to apply the primer;

4. after the surface has dried, the procedure must be repeated again.

Advice! If you need to cover a large area with soil, you can use a spray gun or sprayer.

This completes the priming process.
Paint selection and preparation

Before you paint flat slate or corrugated material, you need to decide on the paint. The best choice in this case, they are polymeric water-dispersion compositions. Moreover, it is necessary to use paints that are designed to cover the roof or facade.

It should be noted that polymer compositions are of three types:

acrylic;

silicone;

latex.

The most durable are silicone and latex paints, however, their price is very high - ~ 4000-5000 for a 10-liter bucket. Therefore, you can use acrylic paint, which is much cheaper, but it is also quite durable.

As a rule, water-based paints are sold white and require tinting. This process consists in adding the required amount of color of the desired color, which allows you to achieve any shade.

As a rule, in stores that sell paint and varnish coatings, there are special tinting machines. They allow you to paint the entire batch of purchased paint in the same color of your choice.

Note! When painting the roof, paintwork should be purchased not only for slate, but also for other surfaces. For example, Zinga anticorrosive electrically conductive paint is suitable for fencing and ebbs. For painting chimneys, it is better to use fire-retardant paints for metal Polistil.

If it is not possible to perform tinting when buying paint, you need to independently determine the proportions of the color scheme, first painting a small amount of the composition. After that, the same amount of color should be added to all containers with paint and mixed thoroughly.
Painting

The final stage is painting, which is performed in the following sequence:

1. before use, the paint must be mixed;

2. then it should be poured into a container into which it will be convenient to dip a paint brush or roller (if flat slate is being painted);

3. after that, the painting tool should be moistened with paint, wring it out slightly and apply a coating to the surface. This stage is the most critical, since it is necessary to ensure that the coating lays down in a uniform thin layer, and at the same time there are no unpainted areas;

4. when the paint dries, the procedure must be repeated again.

This completes the slate painting process. It should be noted that this operation can also be performed using a spray gun.
Conclusion

The process of painting slate is quite simple and fast. However, it must be borne in mind that the quality of the work done depends on the preparation of the surface. Therefore, it is necessary to pay special attention to cleaning the slate from dirt and priming.

Universal paint, which is used not only for painting slate, but also for painting reinforced concrete, plastered surfaces, brick, chipboard, DSP, curb stone and other materials intended for exterior decoration. Paint consumption is one liter per three square meters of surface. German paint for slate roofs In addition to the listed paint products for slate, there are other brands on the market, which allows the buyer to choose the best option, taking into account price and quality. Now there should be no questions about how to paint flat slate or wavy, because they are based on the same asbestos-cement base. Now you know that you can also make an old slate roof stylish. In this case, the whole appearance of the house will change for the better.

1. From the beginning, the first layer is applied, immediately after the primer has dried. The first layer, as a rule, takes about two-thirds of the entire paint, since a clean surface absorbs it very easily.

2. After the first layer of paint has dried, a second layer is applied on top of it, the so-called finishing one. The second layer is applied more carefully and carefully. To apply it, you can use a brush or an apparatus for spraying paint - an airbrush.
For painting roof fit a wide brush or brush that will allow you to thoroughly rub the paint into all the flaws and cracks in the surface.

The spray gun, which can also be rented at the store, will help to significantly facilitate the work and improve its quality.

Cement is taken, diluted to the consistency of liquid sour cream with water, PVA glue is added in the amount of 1 cup per 1 bucket of the mixture. This covers the roof. In this way, you can not only improve the appearance of slate, but also reliably repair small cracks.

Ways to paint slate:

brush painting

This is the easiest way from a technical point of view. But at the same time, it is very difficult to achieve a high-quality uniform coating with a brush, because the coloring is done in strokes.

Spray painting

It is NOT RECOMMENDED to use such sprayers for painting the roof. This is due to the fact that manufacturers do not recommend diluting the paint by more than 5%.
- painting with a professional airless spray painter

Airless spray is the ideal technology for applying paints in construction and renovation. Using a high-pressure pump (200 atm.), the paint is fed through a special hose to the spray gun. In airless spray technology, there is no need to dilute the paint, because such a high pressure is enough to apply paint of any viscosity. When painting a slate roof with airless spray, you can achieve a uniform and uniform coating.

Slate should be painted at a relative humidity of 60% and a temperature of at least 15 degrees. With good surface preparation and correct application acrylic paint will last you more than 10 years.

Painting self-painting slate, do-it-yourself will significantly save your budget for home repairs, as services professional craftsmen not cheap. Having carried out painting once on your own, you will learn how to paint slate no worse than experienced craftsmen.

The fact that the use of paints allows slate to acquire the desired color is understandable. But, in addition to the decorative function, coloring compositions also have more important properties. Recall that slate is a porous material, prone to the formation of microcracks. Water easily gets into them, which, with the onset winter cold turns into ice and begins to "tear" the fibers of the material. The same deforming processes occur when mosses and lichens grow in the pores. The problem of premature destruction of slate is solved by painting. Coloring compositions form a strong film on its surface, blocking access to asbestos cement for water and microorganisms. As a result, the deforming processes are suspended and the slate receives additional years to its operational life.

Painted slate, thanks to a film of paint, becomes smooth. Atmospheric moisture does not linger on it and snow easily melts. And if dirt accumulates on the roof, it can simply be washed with water from a hose or car mini-wash.

Another problem solved with the help of painting is the theoretical harmfulness of slate. The version about the non-environmental friendliness of asbestos-cement sheets came to us from the West and is successfully cultivated by many manufacturers of more expensive and modern roofing materials. Its essence lies in the fact that slate emits asbestos dust during operation, which is harmful to the environment and human health. There is much evidence of the injustice of this opinion, however, if this aspect haunts you, the paint applied to the slate will completely block possible way out asbestos dust and 100% save your health.

Thus, staining slate allows you to:

increase the decorativeness of the roof;

to give asbestos-cement sheets a color with the desired degree of haze (matte, semi-gloss, glossy);

smooth the surface of the slate;

protect the slate from the growth of mosses and lichens on it;

prevent the appearance of cracks;

block the dusting process of slate;

· increase the durability of slate by 1.5 times (subject to periodic renewal of the paint layer).

Type #2 - acrylic paints on organic solvents

These paints are diluted not with water, but with organic solvents. Ingredients: acrylic resin (synthetic latex), colored pigments, additives, organic solvent (most often white spirit). The degree of haze of such paints depends on the resin content. The larger it is, the more pronounced the gloss of the dried film of the composition.

Paint on organic solvents is different:

a stronger film than water-dispersion formulations;

· high water-repellent properties;

elasticity;

Lightfastness and long-term preservation of color intensity;

pungent odour.

Solvent-based acrylic paints are presented on the market in a small assortment. Due to its excellent quality among craftsmen, the Eternit matte paint from Polifarb (Ukraine), produced in red, brown and green tones, has proven itself. Due to wear resistance, the color of this paint practically does not change even by the end of its service life. Another popular option is Shikril paint from KrasCo (Russia). It is characterized by ease of use and a high degree of hiding power.

Type #3 - silicone (silicone) paints

Silicone paints are considered to be the most reliable and durable for slate. They are suspensions of pigments and fillers in an organosilicon (silicone) binder. Due to the presence of silicone, this type of paint is characterized by increased elasticity, so some of them are able to cover cracks up to 2 mm thick!

Properties silicone paints:

high strength;

maximum elasticity, the possibility of carrying out "repair" work and sealing sufficiently wide cracks in the slate with the help of a silicone composition;

· fungicidal and algaecidal properties that prevent the reproduction of microorganisms (in the pores and on the surface of the slate);

high water and dirt-repellent properties;

the possibility of excluding the stage of priming from the painting process;

· silicones are not toxic, have no aggressive smell, are fireproof;

The service life is 10-15 years.

Repeatedly tested for painting slate enamel "KO-slate", produced by the plant "Kremniypolimer" (Ukraine). She soaks upper layer slate, providing deep, long-lasting color. The company produces "KO-slate" in two colors - red-brown and green, however, there is the possibility of tinting to order.

At the same Kremniypolimer plant, OS-5103K enamel (color - green) is produced, intended for protective and decorative painting of many materials, including asbestos cement. The material has increased heat resistance, acid and alkali resistance, resistance to chemical gases. Due to this, painting slate with OS-5103K enamel can be performed at industrial enterprises.

Type #4 - Alkyd Slate Paints

The composition of alkyd slate paints consists of alkyd resins, pigments, fillers in an organic solvent. Alkyd enamels, as a rule, are quick-drying, form an elastic film that is not prone to cracking.

Properties of alkyd slate enamels:

· high moisture resistance;

Increased adhesion to slate;

resistance to atmospheric influences;

Does not require the mandatory use of a primer before painting;

Longevity - 5 years.

As an example of quality alkyd enamel you can bring "Quick-drying enamel for slate" from the company "Impulse" (Ukraine). It is characterized by very fast drying (at 20˚C the layer dries in 1 hour) and does not have a strong odor. It is available in the most suitable colors for the roof: red, brown, blue and green. Another alkyd-based product is Roof Enamel manufactured by Empils (Russia). In addition to high protective qualities, the paint has a wide tinting base, consisting of 10 colors.

Type # 5 - polymer paints "Liquid plastic"

They are a suspension of polymers (polyurethane, vinyl or polystyrene), pigments and additives in a solvent. After the composition dries and the solvents evaporate, the paint forms a thin plastic (polymer) layer on the slate with a glossy or matte surface.

Characteristics of "liquid plastic":

absolute moisture resistance (completely blocks the access of water to the slate);

chemical inertness

· high speed drying;

environmental friendliness;

fire safety (does not burn after drying);

resistance to fading;

application without prior priming;

high frost resistance, as well as the possibility of application with small negative temperatures(up to -10˚C);

Durability of the coating - 10-15 years.

Reliable polymer paint Liquid Plastic is produced by Denalt (Canada). This paint is produced on an alkyd-polyurethane basis, which gives the composition a special strength.

Polymer paint PPG-1 produced by Komoil (Belarus) is another reliable choice. Polystyrene is present in its composition, which, after drying, forms a protective and decorative coating variety of colors. The PS-160 TM "Sticolor" paint (Ukraine) also has a polystyrene base. It is a weather-resistant enamel that forms an elastic surface with a glossy effect.

Variety of colors and tinting options

The most popular paint colors for slate are red, brown, green. They appear in the assortment of most paints. At the same time, the color base of a particular material can include both 5 and 100 various colors and shades. But what to do if you want to paint slate, for example, in a light yellow color, but there is no such shade in the assortment of the selected paint? Coloring will come to the rescue. Most paint manufacturers provide for the possibility of coloring their paints in any tone that matches color catalogs— RAL, NSC, Symphony. Tinting at the enterprise is carried out on special devices, using tinting pastes and paints.

Also, tinting can be done independently by adding tinting paste to the purchased paint, and stirring the mixture with a mixer.

Slate coloring technology

The choice of paint and its color is a responsible process. But, unfortunately, even the most expensive and high-quality enamel cannot guarantee a reliable decorative and protective coating on slate. If you do not follow the painting technology, then the pigmented film will almost certainly behave unpredictably. For example, it will begin to crack, swell or crumble much earlier than the end of its service life (perhaps even a few days after painting). Therefore, you also need to be able to paint slate correctly!

The process of staining slate is carried out in several stages:

Stage # 1 - preparing the surface of the slate

The slate surface to be painted must be free from dust, dirt, fungal and vegetable deposits, unstable (or incompatible with the selected paint) coatings.

Cleaning can be done in two ways: dry mechanical (manual or mechanized) and using water jets under pressure. Sometimes these methods are combined and performed alternately.

For manual mechanical cleaning wire brushes are used to scrape off efflorescence, dirt, moss and lichens. The work requires considerable effort and accuracy, while the cleaning speed is very low. You can clean the slate faster and better with the help of tools. To do this, a nozzle is put on a grinder or a drill, which is, in fact, the same brush for metal. When the tool is turned on, it begins to rotate, cleaning off the surface defects of the slate.

The second cleaning method consists in washing the slate with high-pressure water jets, which are created by car mini-washers (Wagner, Karcher, etc.). In this case, the created pressure should be within 100-250 atmospheres. Mini-sinks that release water with a lower pressure will not be able to remove contaminants, and higher pressure mechanisms will destroy not only defects, but also the slate itself.

Stage # 2 - priming

To impregnate the top layer of slate, apply special formulations- primers. They are selected in accordance with the instructions for use of a particular coloring composition. For example, silicone paint Ko-slate is combined with silicone primer KO-011C. However, organosilicon paints, as well as Liquid Plastic compositions and alkyd enamels, can be applied without prior priming. Acrylic paints, on the other hand, require the use of a primer. These can be either special compounds (for example, Dupa-grund for Alpina DACHFARBE), or paint diluted according to the instructions. To obtain an impregnating primer for Alpina DACHFARBE acrylic paint, it is enough to dilute it with water up to 10% by volume.

The primer is applied to the slate in 1-2 layers with a brush, roller or spray gun.

Stage # 3 - directly painting

On top of the dried primer, direct staining is performed. As a rule, it is enough to apply 2 coats of paint, the first of which will be the base, and the second - the finish. The base layer is the main one, it must carefully cover the entire surface of asbestos cement, including ends, corners, joints, ridge and corner parts. After the first layer has dried, paint a second time. The task of the second (finish) layer is to ensure that the painted slate gets a bright uniform color, without streaks.

Processing is carried out with a brush, roller or spray.

Such a simple technology will give slate color and high decorativeness, comparable to the beauty of tiles, bituminous or metal roofing. In addition, painting (with periodic updating of paint) will become a reliable protection of the roof from exposure to environment and extend its lifespan by decades.

And for sprayers of this type, highly diluted paint is required.

The period of operation of asbestos-cement slate reaches 50 years. However, with proper care, the life of the roofing material can be significantly increased. One of the prerequisites for the durability of slate is its painting. As a result of staining, a protective layer is formed on the surface, and the roof itself acquires an attractive appearance.

Should the slate be painted?

Asbestos-cement slate long time was considered the most popular roofing option due to its good performance and affordability. And today, many prefer this particular material in the construction of buildings for various purposes.

Easy to install and inexpensive slate has some disadvantages:

not attractive appearance;
tendency to fouling with lichen, moss;
gradual decrease in strength characteristics under the influence weather conditions and external factors.

Slate is a porous material prone to microcracks. The moisture accumulated in the pores, during the first frosts, turns into ice and gradually “breaks” the material from the inside. The same deformations are inevitable when lichens and mosses grow on the surface.

These problems will help to solve the painting of asbestos slate. After painting, a strong film is formed on the surface of the roof, covering the access to water and microorganisms. As a result, the destruction processes are suspended, and the service life of the slate is extended by several years.

Thanks to the protective layer, the slate becomes smooth, atmospheric moisture is not retained on it, and snow and fallen leaves quickly disappear. Accumulated dirt can easily be washed off with a mini-wash for a car or with water under pressure from a country hose.

In addition, painting solves another issue - the theoretical harmfulness of slate. This version is mainly distributed by manufacturers of advanced and expensive roofing materials. The essence of the problem is that the slate coating emits asbestos dust, which has a negative impact on the environment and human health. There are numerous refutations of this version. However, for the doubters optimal solution- painting of slate, which will completely prevent the release of asbestos dust.

So, painting a slate roof allows you to:

improve the appearance of the roof and give it the desired color;
smooth out the roughness of the slate;
prevent the formation of cracks;
protect the material from the growth of vegetation on it;
prevent dusting;
increase the service life of roofing material by 1.5 times.

Slate paint must meet many requirements. The main selection criteria: resistance to temperature fluctuations, burnout and precipitation. An important indicator is the level of adhesion with asbestos cement.

For coloring slate, the following groups of coatings are used:

acrylic enamels;
alkyd;
organosilicon;
"liquid plastic".

Most wanted acrylic compounds . They are rich in color different levels haze. Types acrylic enamels: water-soluble or on organic solvents.

Water-dispersed acrylic paint for slate has a number of advantages:

no pungent odor;
fire and explosion-proof thanks to water based;
does not emit toxic substances;
in the process of application does not require a special solvent;
drying speed - about 2 hours;
formation of a waterproof film;
the service life of the coating is 5 years.

Alpina Dachfarbe (Caparol) - enamel green, brown or red, resistant to frost and weather conditions.
"Roofing paint on slate" (Novbytkhim) - forms matte finish resistant to the development of microorganisms. Produced in five colors.
"Aquagel AK-1SH" (Stirol) - LKM creates a smooth film on the slate, from which water quickly drains. Distinctive feature- ease of maintenance of the roof.

latex paint- a kind of water-based acrylic paints and varnishes. It looks like a thick mastic, and after drying it turns into a flexible, elastic film. Such a "rubber" coating does not crack, does not let water through and has excellent adhesion to slate. From colors the most popular paint for slate is acrylic 6005 (green matte), 5005 (blue matte) and 3009 (red-brown matte). Nomenclature of colors according to RAL.

Acrylic enamels on organic solvents are distinguished by:

more high strength than water-soluble paints;
elasticity;
high water-repellent characteristics;
lightfastness;
longer drying time - about ten hours;
pungent odor;
moderate toxicity and fire hazard.

Important! If solvent-based acrylic paint is too thick, then it must be diluted with a solvent that is part of the enamel. Painting work must be carried out away from open sources of flame, using personal protection.

Alkyd slate paints dry quickly and form an elastic film on the roofing material, which is not prone to cracking. Additional advantages of alkyd enamel include:

high hitch with slate;
good moisture resistance;
resistance to natural phenomena;
it is not necessary to prime the surface before painting;
service life - not less than 5 years.

Examples of high quality alkyd paint:

"Quick-drying enamel" (Impulse) - quick drying (within 1 hour at an ambient temperature of 20°C), no pungent odor.
"Enamel for roofs" (Empils) - the strength of the protective layer, 10 colors.

silicone paints- the most durable and reliable option for painting the roof. Silicone betrays enamel elasticity. Some types of organosilicon paints can fill microcracks up to 2 mm thick.

Important! Silicone enamels are the best option for processing old roofs.

Qualitative characteristics of silicone paints:

high elasticity;
the possibility of performing roof restoration and repairing cracks;
fungicidal qualities block the reproduction of microorganisms;
excellent dirt and water repellency;
silicones are fireproof and non-toxic;
durability - service life up to 15 years.

Examples of high-quality silicone enamels:

"KO-slate" (Silicon polymer) - forms a deep color and durable coating, produced in two basic colors with the possibility of tinting;
"OS-5103K" (Silicon polymer) - used for decorative and protective painting of various building materials. Differs in the increased resistance to chemical gases, alkaline and acid environment. Thanks to these characteristics, the paint can be used in industrial applications.

Polymer paints on the surface of the material form a plastic film of matte or glossy texture.

Qualitative indicators of "liquid plastic":

100% moisture resistant - polymer film does not allow moisture to seep to the slate;
drying speed;
harmless to the environment and no fire hazard;
resistance to UV rays;
the possibility of applying silicone enamel without the use of a deep penetration primer;
it is permissible to apply enamel in frosty weather (up to -10 ° C);
durability - service life is about 15 years.

Options for good polymer paint:

Liquid Plastic (Denalt) is produced on a polyurethane-alkyd base, which gives the coating sufficient strength;
PPG-1 (Komoil) contains polystyrene. In the process of drying, a durable layer protecting against moisture is formed.

Important! Polymer paints dry very quickly. Therefore, it is desirable to carry out staining with an airbrush.

Do-it-yourself step-by-step painting of slate

Most often, slate is painted with acrylic paints. Therefore, we will analyze the order of work using this type of enamel.

Paint Volume Calculation

The consumption of coatings depends on the area to be covered and the absorbency of the material. As a rule, for coloring 1 sq.m. slate will be used up about 300 gr. paints. To determine the total volume of enamel, it is necessary to calculate the area of \u200b\u200bthe roof.

The procedure for calculating the area of \u200b\u200ba gable roof:

Measure the length and width of the building. The data is taken taking into account allowances for cornices (about 50 cm).
Perform the calculation according to the formula: S=2*(a*b), where S is the desired roof area, a is the length of the roof slope, b is the length of the roof.

The resulting value should be multiplied by the average consumption of enamel. When determining the total volume of paint, it must be borne in mind that two layers will have to be applied for high-quality staining.

Surface preparation

The longest and most laborious stage is the preparation of the surface for carrying out painting works. The set of activities includes:

Important! The application of paint on the slate should be started only after the primer layer has dried - not less than 12 hours later.

Slate painting technology

It is advisable to prepare brushes in advance different sizes to qualitatively process the ends, corners and hard-to-reach places of the roof. The paint is applied in two layers - the main and finishing.

Important! It is permissible to paint flat slate with a spray gun. When processing wavy material, it is better to refuse it - there is a risk of uneven staining.

The main layer is applied with special care, capturing all areas from top to bottom. After that, the base coat must be left to dry completely and re-apply the paint.

The final layer "evens out" sharp transitions of paint and creates a monophonic, saturated color of the roof.

Features of painting new and old slate

It is better to paint the new slate "below" - before laying the roof. There is an opinion that base layer must be applied on the ground, and the finish - after the installation of the slate. Proponents of this method argue their opinion by possible damage to the enamel when installing the sheets. However, many experts believe that the risk of peeling off the paint layer is associated primarily with the unprofessionalism of the workers and the complexity of the design of the roof itself. It is much easier to cover up local scratches at the top than to apply a full coat of paint.

Old slate is more difficult to process due to a number of factors:

Structural wear. The elements of the crate weaken and sag over time. Walking on the roof can cause cracks in the slate.
Partial destruction of the roofing material. Before painting the old slate, it is necessary to check it for defects. Unusable sheets to be replaced, and minor breaks to be repaired.
Changing the structure of the slate coating. Under the influence of precipitation and temperature changes, the material becomes loose - this creates a danger for workers who paint slate.
The need to clean the surface from accumulated dirt and various growths.

Thanks to modern painting materials, it will be possible to avoid the dullness and dullness of slate. The main thing is to choose the right paint and stick to it. technological process then the result will please for many years.

Do-it-yourself slate painting: video

Most of the old houses are covered with the most available material, which is slate. Its production made it possible to supply not only construction organizations, but also private developers. It is not surprising that the roofs of country houses were covered with this particular roofing material. But time spares nothing and asbestos cement sheets gradually begin to lose their former light grey colour, overgrown with moss and black spots. But such a design cannot suit a person who wants to make his home bright and memorable.

The slate roof of the house is painted in accordance with the design of the facade.

If the slate has lost its appeal

If just roofing does not require replacement, then it would be best to simply paint the slate. It is also worth updating asbestos-cement sheets with a paintwork material to increase the ability of the roof to resist water flows rushing from heaven during rain. But before you paint a slate roof, you should prepare the necessary tools and suitable paint.

Moss-covered slate roof of a house

Methods and materials for giving the roof a new life

To begin with, it is worth stocking up with the necessary equipment, without which the work simply cannot be completed. To do this, prepare:

ladder;
brushes or spray;
rope;
wire brush or portable electric washer.

No need to be surprised to have a portable electric car wash in this list. The fact is that before painting the slate roof, it must be properly cleaned of dirt and other debris. This requirement applies to all types of paint and varnish materials, including rubber paint, which has often become used for roof restoration.

Cleaning the slate with water using a high-pressure apparatus

Cleaning slate with your hands is a rather lengthy and time-consuming process, so it will be much more effective to use a jet of water directed under pressure. The main thing is not to set too high an indicator, otherwise you can simply wash the hole in the asbestos-cement sheet.

From materials it is necessary to prepare:

solvent for paint and primer;
primer for slate;
water repellent;
paint for slate coating (rubber, alkyd or silicone).

Once everything is ready, you can begin such an interesting process as painting the roof of the house.

Carrying out slate roof painting

When the roof is cleaned of debris and dust, and all dust is washed off it, then the slate must be covered with a water repellent. This material will improve water repellency coatings, which will positively affect the roof as a whole. But on the metal part, if any, this liquid should not be. You can cover the slate with a brush or spray. The main thing is that there are no untreated places left.

Treatment of slate with a water repellent by spraying

In addition, this liquid will somewhat strengthen the slate itself. This will not allow the roofing material to collapse under the influence of precipitation and wind. And these are the most best qualities for any paint that will be used in the future, be it rubber or acrylic or even enamel.

When the water repellent dries, you should proceed to the surface primer. This stage will make the surface of the slate prepared for contact with the paintwork. And the durability of the whole work depends on the clutch. And not to get a new repair already on next year should work well with the primer. When it is completely applied, it is necessary to allow the roof to dry. This may take up to 12 hours. And only after that it will be possible to decorate the roofing, giving it the desired color.

Painting the roof of the house is the final stage of the whole process. And it cannot be done carelessly. Like primer, roof paint can be applied by brush or spray. And the roller here will not be very convenient, since the surface of the slate has waves, which makes it difficult to work with this tool. The coating should be applied in two layers. This will give you the best quality results. The surface must dry properly between coats. This is a mandatory condition that must be met strictly.

For the speedy completion of work, it is customary to use acrylic paints, which are diluted with plain water and dry quickly enough. If necessary, up to 10% water can be added to this composition. It is required in a very hot weather when the temperature approaches +35 C. Water evaporates quickly, and thickened paint will not be able to give a high-quality coating.

Applying paint to a slate roof with a brush

The final coat should be evenly distributed, creating an even layer without color differences. The surface of the slate roof will be transformed for the better, which will most favorably affect its perception by others.

Rubber paint will allow you to get a velvety coating that can freely tolerate any temperature changes. It will not crack or peel off even on a metal base. And this is its significant advantage over other options for paints and varnishes for painting roofs.

Painted slate roof of a private house

The slate is painted, the surface is completely dry, but this is not the end of the work. It is required to process the skates and metal junctions so that they look beautiful and attractive. And the task may not be easy, since most of these elements are made of galvanized iron.

What can be done with old galvanizing

On an old metal surface coated with zinc, places can form over time where corrosion has begun to reach the black iron. The basis of this structural element under the influence of water and air is gradually destroyed. Corrosion literally "eats" the metal, which leads to the formation a large number holes. And there will be no talk of any tightness here.

Rubber paint for slate roofing and galvanized parts

Therefore, skates and junctions need protection. And this means that roofing paint on galvanized iron is needed, which will not only give an attractive appearance to these parts, but also strengthen them, extending their service life.

But not every paintwork material can be used for this job. On zinc, which is coated with iron, the resulting film does not hold well. This is due to poor adhesion of materials to the protective metal. Therefore, the choice should proceed from the properties of the given surface.

Painted slate roof and galvanized elements

And here rubber paint can also be used, which has already been used to transform a slate roof. It can be freely attached to the galvanized surface, which only needs to be cleaned of dirt and dust. You can apply this material over rust, but it is better to remove the metal oxide to get a more suitable base.

Works on coloring galvanized iron are carried out in two stages. After preparing the metal surface, which must be clean and free from oil and grease stains, the first coat must be applied. It is worth noting that the rubber paint dries fairly quickly, which provides top speed performance of work. In just a couple of hours, you can apply a second layer, which will make the galvanization attractive and updated.

Separately, it is necessary to say about security measures. Protective equipment such as gloves and goggles should be used when working. Painting at height should only be carried out with insurance, so that in the event of a fall, a person can linger on the roof and avoid negative consequences.

Slate, even in an unpainted state, is a material that is sufficiently resistant to negative external influences.

It is characterized by low price, resistance to corrosion and ease of installation and repair.

But painting the slate significantly increases its operational potential, although it requires additional costs and time. In this article, we will analyze what paint to paint the slate on the roof and how to do it correctly.

The main disadvantage of slate is the possibility of growth of mosses and algae on it. The activity of plants leads to an increase in the size of the pores and the appearance of microcracks, which reduces the operational potential of the roof. The growth of mosses also negatively affects the appearance of the roof.

Another disadvantage of slate is its fading over time. The material peels off, the original structure of the coating is broken.

Proper painting of the slate roof can eliminate these shortcomings. It will increase its moisture-proof properties and give it a pleasant appearance, prevent peeling of the material, the appearance of mosses and fungi on it.

Asbestos is considered a carcinogen hazardous to health. From unpainted slate, asbestos dust constantly emanates into the atmosphere and poisons it., painting the material allows you to minimize this process and make the roof more environmentally friendly.

Initially painted slate can also be purchased from the manufacturer, but this is not as economical as doing this process on your own.

Paint Functions

Paint for slate - how to choose the best paint for the sheet?

Asbestos fibers are not compatible with all types of paints. Least of all, oil and enamel products are applicable for arranging a slate roof.. Simple enamel begins to flake off and hang down a few months after application, but specialized enamels are actively used for arranging slate roofs.

How to paint slate? In addition to specialized enamels for coloring slate, the following types of products are used:

Acrylic. Belongs to the group of water-dispersion products, which are characterized by a high degree of waterproofing. Acrylic fills even the smallest holes in the slate and prevents the reproduction of fungi and plants in them. The paint is represented by such brands as Akrilakma, Triora, Novbytkhim.
modified acrylate.
silicone paints. Extend the life of the slate by an average of 5 years. They have good adhesion (adhesion to the roof surface). The main disadvantages are high price and in 10-15 years completely burn out on sunny side roofs
Acrylic silicone products. They combine the best qualities of both types of paints. Manufacturers: Penta, Sofexil.
polyurethane products.
Liquid plastic. High-tech material, characterized by low price and high resistance to mechanical and atmospheric influences. But liquid plastic is toxic, which increases the need for caution when installing it.

One of the best materials in terms of price, quality, ease and safety of coloring is acrylic.

Surface preparation

If the slate has already been used for a certain time, then it is impossible start painting it without preparatory procedures.

It is necessary to clean it from accumulated plants, fungi, dust and asbestos chips.- the paint will not be applied properly to the uncleaned slate.

All cracks and breaks should also be repaired.

Small cracks are sealed with a cloth impregnated with waterproof glue. Larger breaks should be filled with loose asbestos mastic, PVA glue and cement.

NOTE!

If the roof is covered with large and numerous cracks, large pieces of material break off from it, then there is no point in painting it, it is better to purchase and install a new slate. Optional to install new design from scratch, it is enough just to replace the sheets that have become unusable.

You can clean the slate both manually with a stiff brush for metal, and with a sink that creates a jet of water with strong pressure. The first option is very time consuming, cleaning the roof with a brush can take several days, and a good result will not be guaranteed, since not all formations can be removed manually.
Instead of a brush, you can use an electric drill with a special nozzle, the disadvantage of this method is the risk of damaging the slate with such a rough tool.
Cleaning with a sink is easier and faster, but it is important to choose the right water pressure. Too low a pressure will not be enough to remove germinated plants, if it is too high, the jet can damage the slate. The optimum pressure is 200-250 atmospheres.
After cleaning the roof, it must be disinfected. Antiseptics are used for this purpose. They are applied over the entire surface of the roof with a brush or sprayer, the second option is more preferable.

CAREFULLY!

All preparatory work is carried out in a respirator and glasses to avoid getting asbestos chips and cleaning materials into the respiratory tract and eyes.

The last stage of preparation is the primer. It improves the adhesion of paint and roofing material. It should be applied with a roller or brush over the entire area of slate. Some types of primers are additionally antiseptics.

Asbestos cement has a high permeability, so almost any primer is suitable for it. It should be applied at an air temperature of 5 to 30 degrees above zero. The average drying time of the primer is 12 hours, after this period you can start painting.

Slate cleaning

How to paint slate with your own hands

Craftsmen's advice recommends painting slate in two layers. The first layer is the main one, 2/3 of the materials are spent on it. The interval between applying layers is from one to two hours.

Slate painting is carried out with the help of brushes and spray guns. Spray guns speed up the process, make it more convenient. But you need to work out the corners and other hard-to-reach places on the slate sheets manually with a brush.

Most the best time for painting - these are warm and moderately cloudy days.

At low or high air temperatures, with high humidity or under the scorching sun, work will be impossible. It is desirable that the weather be favorable the next day after their completion.

Average paint consumption per square meter with two-layer application is 100-200 grams, but you should always buy materials for the future, since situations are not ruled out when you need them additional expense. Paint should be applied from top to bottom.

If the result of two-layer painting is not satisfactory, then Additional coats may be applied until the finish is smooth and pleasing to the eye.

Applying paint to new slate is relatively easy, as work can be done on the ground before the sheets are installed on the roofing pie. If the slate sheets are in an inclined position, then achieve their uniform filling paintwork materials it will be hard.

If the slate is painted on the ground, then when climbing to the roof, its coating can be scratched. To avoid this, only the first layer of paint is applied to the roofing cake before installation, and the second layer is applied after the installation of the roof is completed - it hides the scratches that have appeared.
