What paint to tint the polymer layer on the metal tile. How to paint a roof (metal tile)? Types of polymer coating for metal tiles and flashings
Metal roofing has long been a commonplace in construction industry. According to statistics, with its help, more than 25% of the roof surfaces of residential buildings are protected from wind and atmospheric influences.
This indicates high operational properties this roofing material, but, despite this fact, from time to time it needs restorative repairs.
Reasons for Restoring Coverage
It should be noted that painting of metal tiles may be required in case of physical impact:
- Damage during delivery to the construction site (chips and scratches during loading and unloading operations);
- During the installation of sheets on the roof (careless handling, falling heavy tools, etc.);
- Due to the occurrence of damage during the operation of the building covered with this roofing material (falling tree branches, large debris, snow blocks or ice).
Tip: Repair paint, often sold by the manufacturer of the roofing material, will help in this matter.
Besides, climatic conditions can also affect the durability of the metal tile coating:
- Burnout under the scorching sunbeams;
- Tarnishing as a result of exposure to acidic rainfall.
Note!
In this case, we are talking about a global update. paintwork the entire surface.
And before you paint the metal tile with a new composition, you should carefully select it, taking into account climatic features your region.

Types of paintwork materials
Having dealt with the reasons, you should talk about existing, intended for do-it-yourself use.
But first, it is necessary to mention the properties of the metal tile:
- Susceptibility to corrosion in places where the metal layer is exposed;
- Availability of additional polymer layers, preventing the adhesion of the applied paint;
- The presence of zinc protection, etc.
All these factors have an impact on the technology of applying a new paint and varnish coating.
enamels
Most often on sale you can find enamels offered as repair kits. They are packaged in cylinders with a capacity of 250-400 grams, have various colors, tinted under a single
European standard(RAL) and having the following parameters:
- Excellent adhesion;
- Compatibility with polymer coatings;
- Good hiding power;
- Fast drying from 10 to 30 minutes;
- Permissible thickness dry film - from 20 to 25 microns.
Note!
Such paints are intended for fresh damage, in which metal corrosion does not have time to appear.
Paints
It's a different type paintwork materials, designed for use on surfaces that have a long operational period - from two years or more.
They contain special protective substances:
- Rust converters;
- copolymer resins;
- inorganic pigments.
Accordingly, they have other performance that should be taken into account:
- Complete drying time - at least 6-8 hours in dry and calm weather;
- The application of paint is permissible only after a thorough washing of the surface with alkaline agents.
Note!
To prepare the surface of the metal tile for painting after many years of operation, it must be washed special tool.
Surface treatment and subsequent washing with water is guaranteed to remove all types of contaminants from galvanized surfaces:
- Zinc salts;
- Dust and dirt;
- Other chemical impurities deposited on the roof.
Only after complete drying of the roof surface can be applied new paint with the help of a spray gun.
Self application
Most Damage roofing systems are discovered by the owners themselves, respectively, and the decision to repair is dictated after visual inspection scope of work and its complexity:
- Fresh scratches and chips are easy to paint over with spray paint, while observing safety precautions when working at height.
- If we are talking about a complete renovation of the paintwork, then you should pay attention to technical specifications roofs and on your physical and technical capabilities- ability to work long time at a height and the availability of safety equipment.
When it comes to roofs low angle tilt - it makes sense to do the staining yourself
Note!
The price of such work from specialized companies is high, but they are also responsible for the life and health of workers.
Finally
Despite the high performance characteristics metal tiles, even she needs repairs from time to time. It is only important to choose the right method and paint for restoration damaged area while taking precautionary measures. And the video in this article will help you visually familiarize yourself with the stages of work.
The metal tile has a lot of advantages as a roofing material. The main ones include good strength characteristics, durability and versatility. But there is one more important detail, thanks to which the metal tile occupies a leading position in modern market among other analogues. It's about a variety of shades and colors. outer coating. Therefore, the owners country houses and cottages, there is always the opportunity to choose the color option for the roof that best fits into the general background landscape design. Paint for metal tiles may be needed in different occasions. For example, after some time you wanted to change the color of the roofing surface and renew it, or the metal tile in some places needs to be painted over scratches.
Reasons for painting metal tiles
You may need special paint in such cases:
- During careless transportation, the protective layer metal sheets was damaged.
- During operation, due to corrosion processes, the top layer was damaged in some places.
- Mechanical damage to the sheets of metal tiles laid on the roof.
- The developer wants to change the color of the roof.
One way or another, for whatever reason you would have to change color or tint, you solve several problems at once. Firstly, this is the correction of defects, and secondly, attach the roof surface fresh look. But in order for everything to work out the way you intended, you need to choose the right paint for metal tiles.
Rules for choosing paint for different occasions
Painting can be different - full or local, the budget can also be different. Therefore, based on these factors, paint is usually selected. The buyer also looks at the manufacturer - famous company or not. In any case, you have the opportunity to choose a paint for metal tiles from the proposed types:
Repair paint is often included in the kit along with sheets of metal. Great for painting small defects, chips, cracks.
Paint for restoration is sold in pencil tubes. Its main purpose is the treatment of small flaws on the surface.
The enamel product is intended for application to galvanized or steel materials. It is perfect for restoring old surfaces, as well as for painting new ones. Paint is sold in sprays or cans. First container option better fit to repair local damage, and the second - for staining large areas roofs.
Acrylic paint is used for processing, for example, joints of sheets affected by corrosion.
But paint alone will not be enough, you will have to buy other tools - brushes, spray guns, rollers.
Preparing the roof surface for painting
Of course, before painting the surface must be well prepared. If you do not make certain preparatory work, then the painted surface will soon become unusable again. First of all, the problematic metal sheet is carefully cleaned from old paint and rust. After that, the cleaned material is well washed and dried.
The next stage is the application of a primer and directly, the paint itself. If you plan to paint in several layers, then it is imperative to take a break of 7 days.
Of course, in order for a metal roof to serve you for a long time, it is important to immediately purchase material High Quality. Much will also depend on the quality and the paint itself. To make your choice right, consult with specialists from the Ilirt company.

Types of paintwork materials
Having dealt with the reasons, you should talk about existing types finishing paints intended for do-it-yourself use.
But first of all, it is necessary to remember the properties of metal tiles:
Tendency to corrosion in places where the metal layer is exposed;
The presence of additional polymer layers that prevent paint adhesion;
The presence of zinc protection, etc.
All these factors affect the technology of applying a new paintwork.
enamel
Most often on sale you can find enamels offered as repair kits. They are packaged in cylinders with a capacity of 250-400 grams, have different colors.
The European standard (RAL) has the following parameters:
Excellent adhesion;

Permissible dry film thickness - from 20 to 25 microns.
Note!
Such paints are intended for fresh damage, in which metal corrosion does not have time to appear.
To apply paint to a damaged area, it must be cleaned with a clean rag from dust and painted over by directing a jet from a distance of 20-30 cm. If the scratch is deep enough, then the instructions require applying a second layer after drying.
dye
This is the second type of paints and varnishes designed for use on surfaces that have a long service life - from two years or more.
They contain special protective substances:
Rust converters
copolymer resins;
inorganic pigments.
Accordingly, they have other operational qualities that should be considered:
1. Complete drying time - at least 6-8 hours in dry and calm weather;
2. Application of paint is permissible only after a thorough washing of the surface with alkaline agents.
Note!
To prepare the surface of the metal tile for painting after many years of operation, it must be washed with a special tool.
Surface treatment and further washing with water is guaranteed to remove all types of contaminants from galvanized surfaces:
Fat;
Zinc salts;
Dust and dirt;
Other chemical impurities deposited on the roof.
Only after the roof surface has completely dried can new paint be applied using an airbrush.
Paint and do-it-yourself application
Most of the damage to roofing systems is created by the owners themselves, respectively, and the decision to repair is dictated after a visual inspection of the scope of work and its complexity:
1. Fresh scratches and chips are easy to paint over with spray paint, while observing safety precautions when working at height.
2. If we are talking about a complete renovation of the paintwork, then you should pay attention to the technical parameters of the roof and your physical and technical capabilities - the ability to work for a long time at height and the availability of safety equipment.
Note!
The price of such work for specialized companies is high, but the responsibility for the life and health of workers lies with them.
If the future scope of work is sufficiently safe, for example, sloping roof, or the presence scaffolding, it is quite possible to carry out these works independently. It is only important to make as little physical impact on the roofing material as possible.
Finally
Despite the high performance characteristics of the metal tile, even it needs repairs from time to time. It is only important to choose the right method and paint to restore the damaged area, while observing the precautions. And the video in this article will help you visually familiarize yourself with the stages of work.
It would seem that the metal tile is an almost perfect building material that does not need additional care. However, there are situations when paint for metal tiles is simply necessary.
The most common case is damage in transit. Paint for metal tiles will hide all chips and defects in the coating, and the work itself can be done even before installation. It also happens that in order to save architectural style buildings need to change color building material. And in this case, paint for metal tiles will help.
During the long service life bright colors roofing can also fade, fading under the rays of the sun. It makes no sense to dismantle the roof when paint for metal tiles can solve all problems. In the event of damage to an already installed roof, paint for metal tiles will also provide excellent protection for defective surfaces and significantly increase the life of the roofing.
There are two ways to change the color of the roofing material. Before its installation - on the ground, or, if the coating is already installed - on the roof. In the latter case, it is necessary to additionally attend to the safety of work, especially if they are carried out at a considerable height. No less attention should be paid to the technology of painting: you can give preference to both traditional brushes and rollers, as well as spray guns or paint sprayers.
The main thing you need to know about: paint for metal tiles provides a significant reduction in the cost of finishing or operating a building, because you can change the shade of the roof yourself, you just need to choose the right means for painting.
The range of paint for metal tiles is presented in four shades: chocolate, brown, green and red.
A wide range of metal tiles appeared on the roofing materials market at the beginning of the 2000s, and if at first it was a rather expensive way to cover a roof that only a few could afford, then today metal tiles have become perhaps the most common roofing option when building a new house or repairing old. Metal tiles, as a rule, are sold already painted, there is enough wide selection colors and shades, however, you can also buy unpainted metal tiles by choosing the color or shade you need, in which case it will be covered with a factory-made polyester film.
IN WHAT CASE SHOULD WE FACE THE NEED TO PAINTING METAL TILES?
· Coloring of a new product. In the event that you did not find a metal tile desired color best suited to your home, you can paint it yourself
Repair painting. If the surface of the metal tile was damaged during transportation or installation, it is better not to wait until your new roof will begin to rust and tint it immediately after installation
Re-staining. If your metal roofing has been in service for several years, has begun to corrode, or the old paint is peeling off, you can repair the damaged areas or the entire roof.
· Creative mood. After all, maybe you just wanted to decorate your Vacation home, put a picture on the roof, paint it in all the colors of the rainbow.
So, whatever the reason for painting the roof of a metal tile, we will tell you in detail how to do it correctly so that the material is protected from corrosion and wear, does not fade in the sun and serves you faithfully.
WHAT IS THE METAL TILE PAINTED WITH? THERE ARE SEVERAL BASIC PAINT OPTIONS:
1) Acrylic enamels. Advantage - big choice colors, good protection against corrosion, easy to apply, dry quickly. With constant exposure sunlight, precipitation, temperature fluctuations have a service life of 5 years or more. Apply by roller, spray gun or aerosol can
2) Ordinary alkyd and other oil enamels are also quite suitable for painting
3) Special enamels for painting metal tiles are best suited for our task. As a rule, these are high-quality alkyd enamels with an additional protective component that protects metal and galvanized surfaces from corrosion.
Subject to the painting technology, the service life of the coating is 10 years or more.
Having decided on the paint, we will compile a list of tools and improvised means that we may need in the process of painting our metal roof.
.
WHAT DO YOU NEED TO PAINTING METAL TILES WITH YOUR HANDS?
Of course the paint. Paint for metal, alkyd enamel or special enamel for metal tiles in sufficient quantities.
Sandpaper or a metal brush to clean the surface
Newspaper or film to cover surfaces not to be painted
masking tape
Facilities personal protection: gloves, mask, clothes
Basin of water, cotton rags, detergent
Primer, normal acrylic or primer-enamel on rust will do
INSTRUCTIONS FOR PAINTING METAL TILES WITH YOUR HANDS
Before we get started, let's do a few important notes:
· If you are completely painting a new metal tile, it is better to do it before installation, as in this case it will be easier for you to apply the paint qualitatively and evenly. The same applies to the option of repair painting of metal tiles damaged during transportation.
· Preparatory work and painting should be carried out in the warm and dry season, it is desirable that the air temperature be at least 15 degrees.
So let's get straight to work:
Wipe the surface of the metal tile thoroughly with a damp cloth. If it has any greasy spots or extraneous heavy contamination, white spirit, acetone or special cleaners can be used for cleaning
If your roof has already been painted, it is advisable to remove the entire layer of old paint. To do this, you can use special removers for old paint or a good old metal brush and chisel.
If the metal tile has been severely damaged by rust or corrosion, use rust removers or sandpaper to properly clean the damaged surfaces.
Before proceeding to painting, we advise you to degrease the surface, this will be a guarantee that the paint will last long years not just one season. For degreasing, use special formulations or ordinary white spirit, at worst - kerosene

You are probably already impatient to do the painting itself, but before you paint the metal tile, you should prime it. To do this, you can use a special aerosol primer, and if your roof had rusty areas, we recommend using a rust primer. A well-primed metal tile surface will give the most durable paint base and prolong the flawless life of your new roof.
So, let's move on to the most important and exciting stage - painting the metal tile.
If you are painting with a special spray paint for metal tiles, then shake the can thoroughly before painting so that the contents have a uniform consistency. Enough 10-20 seconds. To avoid paint streaks, paint the metal tile from top to bottom, applying paint from a distance of 25-30 cm. Make sure that the paint lays down evenly and all areas are painted equally well
As a rule, the metal tile is painted in 2-3 layers. Allow the previous coat to dry before applying the next coat of paint.
If you paint acrylic paint 20-40 minutes is enough for this. If you use alkyd enamels, it will take from 2 to 6 hours, depending on air temperature and weather.
It is strictly forbidden to paint a metal tile with sub-zero temperature or in the rain! After you have applied the last coat of paint to the roof, let it dry for 1-2 days
After you have completely completed the painting and drying of the metal tile, install the necessary fittings and decorative elements, attach gutters, gutters, etc.
Your new metal roof looks like new and will serve you for many years!
1 Preparatory work and painting should be carried out in a warm and dry season, it is desirable that the air temperature be at least 15 degrees.
High-quality roof coating with good paint will extend the life of a metal roof and delay re-painting for a long time.
Roof painting work should be carried out in dry, calm and cool weather. The best time for such work is the end of spring or the beginning of autumn. You also need to take care of security. To do this, choose shoes with rubber or felt soles. Shoes should not slip and leave scratches on the metal. Work at height must be carried out using a safety belt or rope.
You need to prepare the following tool:
1. Step-ladder or scaffolding.
2. Personal protective equipment (gloves, respirator).
3. Brushes with artificial bristles for cleaning dust and dirt.
4. Brush with metal teeth for cleaning rust.
5. Sandpaper or mesh.
6. Sandpaper holder.
7. Brushes 75-200 mm.
8. Roller 250 mm.
9. Mixer for mixing paint.
Preliminary preparation of the surface of the metal tile
You can't paint the roof without pre-training surfaces. Careful Preliminary processing metal sheets will increase the adhesion (sticking) of the paintwork and ensure the reliability and durability of the surface.
If the roof is new, then you just need to dust the surface by wiping it with a slightly damp cloth. In the case when the metal on the roof is not new and worn out enough, it is necessary to carefully clean the surface of dirt, dust and rust deposits, to replace completely rusted steel sheets. Check Status downpipes than manual way metal roof cleaning.
Replace drains if necessary. Remove rust with a special brush with metal teeth or a rust converter. Treat old, peeling paint with a special paint remover, and then remove it with a spatula. If the surface is treated with a rust converter or remover, then it is necessary to use rubber gloves and goggles.
It will be possible to start painting in 4-5 days. A metal roof can also rust from the inside, that is, from the side of the attic. To prevent rust from appearing on the metal from the attic side, it must also be thoroughly cleaned and prepared for painting, and then painted over.
Coloring of metal tiles
Most often, oil paints or alkyd enamels are used to paint ferrous metal roofs, which have high weather resistance. But we must not forget that before painting the roof with such paints, the surface must be primed. For priming metal, a special anti-corrosion primer is used. The primer is applied with a brush on a cleaned and degreased surface, safety belt and rope.
Then 2 coats of topcoat are applied. In order to save time and not cover the roof with soil, you can purchase special paints for metal. They combine the properties of anti-corrosion primer, decorative enamel and rust converter. Therefore, they are applied directly to rust. These paints are highly resistant to water, temperature fluctuations and UV rays.
Often galvanized steel is used for roof cladding. Galvanized sheet also needs to be painted, as under atmospheric action a thin layer of zinc is destroyed. Conventional alkyd enamels are not suitable for painting galvanized surfaces. Alkyd enamel when applied to a zinc surface, it oxidizes, loses its cohesive (adhesive) properties and peels off. It would be best to paint the galvanized metal tiles with special acrylic enamels or paints that are designed for galvanized iron.
Information about the appointment is always indicated by the manufacturer on the label of the jar. Acrylic enamels have more a high degree elasticity than alkyd, and do not lose it during operation.
The elasticity of the paintwork is very important, since the metal is subject to expansion due to temperature changes. The film formed by alkyd-based enamels is destroyed, and the coating peels off from the metal surface.
Before applying the first layer, the paint must be thinned up to 10% with a thinner intended for this type of enamel. This is done so that the first layer adheres well to the surface, penetrates into all the pores of the material.
Before starting work, the paint must be mixed well. Paint metal roof you need from the skate to the slopes, painting over the entire surface of the slope. A fly brush 90-120 mm is suitable for applying paint. Smooth sheets slopes are painted with a 250 mm roller. The service life of the painted surface will be extended if you monitor the health of the water drain system. Water must not accumulate on the roof surface. Before buying paint, you need to calculate the area of \u200b\u200bthe entire surface that needs to be painted. The average paint consumption is 200 ml per 1 sq. m.
How to prepare a roof from a metal tile and eliminate minor defects?
Before proceeding to repair work, you need to carefully and well prepare the surface of the roof, clean it. Remove all dirt, remove rust.
Carefully paint over the damaged areas 2-3 times, shading the paint. Before applying the next coat of paint, the previous one must dry completely.
The partner will help to identify all the defects that have arisen in the roof during its operation - cracks, crevices, holes, etc. How to do this? Split up - let your assistant go to the attic while you climb onto the roof (or vice versa, which is not important). On a sunny day, even the smallest holes in the roof are clearly visible from the attic. Having identified such a defect, you need to knock from below in the place of the defect (for this, a long stick is used). A participant in the process, located on the roof, carefully traces the indicated place in order to repair it later. Combs that are loosely adjacent to each other can be sealed with a hammer or mallet. Cover the remaining small holes between the ridges with putty.
How to make putty for metal tiles yourself?
Building materials stores offer putty ready for roof repair, but you can do it yourself. You will need dry chalk, sifted through a fine sieve, and natural drying oil. You can tint the putty with paint (dry or oil). The ratio of chalk and drying oil is selected empirically, so that the result is a dough consistency for pies (thick and elastic). The putty will adhere securely to the roof surface, and with a knife you can smooth it out well. Then it dries slowly without cracking. Perfect option for filling small holes! And to put a patch on a hole large sizes, you need to dilute the putty to the consistency of thick sour cream, apply a layer of putty on the cleaned surface, and put a piece of tarpaulin (or other dense fabric) on top of the putty. And the already dried patch is painted.
If you decide to repair the roof of a metal tile, consider the important nuances.
First you need to carefully paint over it at the patch site. Be sure to wait until the painted area is dry.
Next, you need to cut out a piece of tarpaulin (absolutely dry fabric!) And dip the future patch into a special mixture: paint (of sour cream density) from grated red lead on a natural basis (you can take grated iron red lead). In this mixture, the patch should be 15-20 minutes.
The impregnated piece of fabric is removed from the solution, squeezed out and placed on the repaired area. The patch must be pressed very firmly against the roof, smoothed out well (a hard brush or just by hand will do). Pay special attention to the edges of the patch - they must be very carefully smoothed!
Let the roof dry for a week. Your roof will become strong and will not leak.
In the case when the detected defects of the metal tile occupy a decent area, and you decide to re-lay individual sheets of the roof, they also need special training. Everyone steel sheet must be primed before laying: apply a thin layer of liquid oil paint (e.g. with a rag, roller, brush). The sheet dried after painting must also be painted on the second (rear) side. Let the sheet dry well. Only such a prepared sheet can be used to repair the roof.
Paint for metal tiles: which one to choose, how and with what to apply?
To paint the roof, you can use large brushes, the bristles of which have high rigidity. These fly brushes will help the roofer thoroughly rub the paint into the roof surface, which has great importance. But experts do not recommend using a roller. This tool applies paint without rubbing it in. The result is a thick surface layer, which then easily wrinkles, cracks and peels off. A lot of paint is consumed, inefficiently, and as a result, everything will have to be redone.
In the building materials market, paint for metal tiles is presented in a very wide range. Gotta choose oil paint manufactured at the factory. Of course, someone decides to make their own roof paint by mixing drying oil and colored pigment. But do not chase cheapness, do not save money: factory paint for a metal tile roof is more durable, since the technology for its preparation has been carefully worked out. There is not a simple mixing of ingredients, but many hours of grinding all the components with the help of special equipment.
How and with what to paint a metal tile?
Aerosol paint for galvanization, ferrous metal, metal tiles and corrugated board is characterized by the following features:
Resistant to atmospheric influences;
Does not fade in the sun
forms durable coating with maximum corrosion protection;
This is enamel reusable;
Convenient during direct installation;
Resistant to temperature extremes
Enamel in an aerosol for galvanizing, metal tiles and corrugated board - does not require preliminary priming, and the improved adhesion of this paint allows the latter to be applied directly to bare metal.
Enamel is designed specifically for the restoration and full coloring of such materials as:
metal tile;
professional flooring;
· self-tapping screws;
any other steel and galvanized surfaces (including surfaces that have been coated with polyester, powder or polyurethane paints);
RAL colors:
Mode of application:
Before applying paint for corrugated board, metal tiles, galvanization, steel and ferrous metal from an aerosol can to the surface, the surface should be prepared for painting: clean, sand and degrease with a solvent.
Mix the contents of the aerosol can with paint by shaking it for at least 2-3 minutes.
While using the paint, it is recommended to periodically shake the aerosol can.
Before applying enamel for corrugated board, metal tiles, galvanized, steel and ferrous metal - make a test spray from an aerosol can and make sure that the paint comes out evenly from the can.
Hold the paint can upright while painting.
Spray paint - spray should thin layer from a distance of 25-30 cm onto the surface to be painted.
In order to achieve as much as possible best result it is necessary to apply several thin layers of enamel, and not one thick one.
If necessary, apply the next layer of enamel. You can apply it 5-10 minutes after the previous painting.
With partial use of enamel, turn the aerosol can with the valve down and spray until the jet becomes discolored. This will allow you to use the aerosol can of paint many times.
Characteristics:
Drying time: 5-7 minutes at a temperature of 25 0C, complete drying time - 24 hours;
Consumption per 1 bottle: 400 ml - depending on the layer thickness 1.5 - 2 m2;
Security measures:
The spray paint can is under pressure!
Do not use enamel in an aerosol can near open flames.
Do not pierce or burn the aerosol can after use.
Spray paint should only be used in rooms with good ventilation.
Paint - spray should be protected from children!
Storage:
The shelf life of enamels in aerosol packaging is 3 years and is indicated on the packaging.
Do not allow direct sunlight to hit the bottle with enamel!
Do not use or store spray paint at temperatures above 50 0C.
How much paint is required for roofing works on a metal tile?
Approximately, you can give the following data per 1 m2:
ocher - 0.18-0.2 kg;
iron minium - 0.035-0.040 kg;
copper paint - 0.25-0.28 kg.
And though last option It seems the most expensive, at first glance, it is the verdigris paint that will last the longest.
If bubbles appear when painting the roof, this indicates that the surface was very poorly prepared for painting. Therefore, we emphasize once again: the roof must be absolutely dry and clean before painting, and the primer and putty applied to the surface must be completely dry by the time of painting. Take your time, follow the instructions, and then you will not have to regret the result.
How many times do you need to apply paint on a metal tile?
Many people ask themselves: how to paint the roof of the house so as not to overspend the paint, but also to make the painting of high quality? The advice of experienced roofers is as follows: for the first layer, the paint needs to be slightly diluted, based on 1 kg of paint:
1 layer - 600-700 g of drying oil;
2 and the next layers - 400-500 g of drying oil.
After applying the first coat of paint, let the roof dry well. This will take at least 5 days (preferably a week). The second layer of paint dries longer - up to 10 days. If you want, after this time, you can apply a third coat of paint. Experienced Builders emphasize: do not rush! Even if it seemed to you that after 2 days your roof was completely dry, apply the next layer early!
During the staining, you need to constantly stir the paint. It is better to start the process from the slopes, and when they dry, proceed to painting the entire surface, along the slope. Carefully shade the paint with a thin layer, do not pick up a lot of paint on the brush at once! Move from the skate to the slopes. Do not leave streaks, stripes, do not apply paint across the slope. And your roof will shine with newness.
Metal roofing has its drawbacks. First: a lot of waste on complex roofs. If the roof has many fractures, drops, lanterns, turrets, etc. the cost of material and labor skyrockets and it is much more difficult to ensure that there are no leaks. The loss of 30% of the material for overlaps and trimmings is an absolutely common occurrence for metal tiles. In this regard, the metal tile plays a great soft roof.
Secondly: some people are annoyed by the noise that comes from metal tiles during rain. Especially when a person is trying to sleep on attic floor right under the roof. Here it must be said that in many ways this problem is exaggerated by unscrupulous sellers of other roofing materials. Of course, metal tiles make more noise than natural tiles, shingles or ondulin. But if the roof insulation is done correctly and in good amount then noise will never be a problem for you.
Third: condensation. Lots of condensation. In the morning, about 10 liters of condensate forms on a medium-sized roof per hour. Therefore, under the metal tile there must be a special anti-condensation film. It is also very important to pay due attention to the ventilation of the under-roof space.
Fourthly, metal tiles have all the disadvantages of metal, such as corrosion. Any untreated scratch to the metal (and scratching a metal tile is easy) sooner or later will be covered with rust and then problems will begin. In addition, the metal tile can easily bend if you walk on it carelessly. And one more thing: during any work with metal tiles (for example, when installing passage elements), you cannot use acetic sealant, because. it corrodes the polymer coating of steel.
Fifthly: self-tapping screws will be unscrewed from the crate. Sad but true. It is highly desirable to tighten them again so that the metal tile is firmly pressed against the crate. Once a year, inspect the metal tile for loose screws.
Sixth: there is a problem of "colourfulness". In my practice, it has repeatedly happened to find out (sometimes already on the roof during the installation process, or even after) that the sheets of metal tiles differ in shades. This happens because in the warehouse of the seller the metal tile can be from different batches. Different batches of metal tiles from the same factory almost always differ in shades, sometimes very significantly. So you should pay attention to this point when buying a metal tile. Ask the seller to control the shipment so that you are shipped sheets of metal from one batch.
Finally, I would like to warn you against buying extremely cheap metal tiles. As a rule, the cheapest metal tile - domestic production. It is worse than imported, first of all, in that its level of galvanization is as low as possible. 190 g/m2. It is not enough. A minimum of 250 g/m2 is required (as with Finnish metal tiles). Such tiles should not be installed on a house in which you plan to live for a long time, because it is guaranteed to give you unpleasant surprises. Just remember the quality of the metal from the domestic auto industry. Is everyone happy? Having saved when buying the cheapest metal tile, you will overpay many times over later. After all, remodeling is always much more expensive than building from scratch.
Also, you yourself can easily check whether the thickness of the metal tile matches what the seller claims. To do this, you need to buy a mechanical micrometer, it costs only 600 rubles. But for this little money, you will surely know that you will not be deceived. And remember that according to GOST, the thickness tolerances of metal tiles are 0.06 mm. This means that under the guise of a metal tile with a thickness of 0.5 mm, you can legally sell a metal tile with a thickness of 0.45 mm.
Reasons for Restoring Coverage
It should be noted that painting of metal tiles may be required in case of physical impact:
· Damage during delivery to the construction site (chips and scratches during loading and unloading operations);
· During the installation of sheets on the roof (careless handling, falling heavy tools, etc.);
· Due to the occurrence of damage during the operation of the building covered with this roofing material (falling tree branches, large debris, snow blocks or ice).
Tip: Repair paint, often sold by the manufacturer of the roofing material, will help in this matter.
In addition, climatic conditions can also affect the durability of the metal roofing:
Burnout under the scorching sun;
· Tarnishing due to acid rain.
Note!
In this case, we are talking about a global renewal of the paintwork of the entire surface.
And before you paint the metal tile with a new composition, you should carefully select it, taking into account the climatic characteristics of your region.
Types of paintwork materials
Having dealt with the reasons, you should talk about the existing types of finishing paints intended for do-it-yourself use.
But first, it is necessary to mention the properties of the metal tile:
Susceptibility to corrosion in places where the metal layer is exposed;
· Presence of the additional polymeric layers interfering adhesion of the put paint;
· Presence of zinc protection, etc.
All these factors have an impact on the technology of applying a new paint and varnish coating.
Most often on sale you can find enamels offered as repair kits. They are packaged in cylinders with a capacity of 250-400 grams, have different colors, tinted under a single
European standard (RAL) and having the following parameters:
· Excellent adhesion;
· Compatibility with polymer coatings;
· Good hiding power;
· Fast drying from 10 to 30 minutes;
· Permissible dry film thickness — from 20 to 25 microns.
Note!
Such paints are intended for fresh damage, in which metal corrosion does not have time to appear.
To apply paint to a damaged area, it must be cleaned of dust with a clean rag and painted over, directing a jet from a distance of 20-30 cm. If the scratch is deep enough, then the instructions require applying a second layer after drying.
This is another type of paints and varnishes, designed for use on surfaces that have a long service life - from two years or more.
They contain special protective substances:
Rust converters;
· Copolymer resins;
· Inorganic pigments.
Accordingly, they have other operational qualities that should be considered:
1. Complete drying time - at least 6-8 hours in dry and calm weather;
2. Application of paint is permissible only after a thorough washing of the surface with alkaline agents.
Note!
To prepare the surface of the metal tile for painting after many years of operation, it must be washed with a special agent.
Surface treatment and subsequent washing with water is guaranteed to remove all types of contaminants from galvanized surfaces:
Zinc salts;
· Dust and dirt;
· Other chemical impurities deposited on the roof.
Only after the roof surface has completely dried can new paint be applied using an airbrush.
Self application
Most damage to roofing systems is detected by the owners themselves, respectively, and the decision to repair is dictated after a visual inspection of the scope of work and its complexity:
1. Fresh scratches and chips are easy to paint over with spray paint, while observing safety precautions when working at height.
2. If we are talking about a complete renovation of the paintwork, then you should pay attention to the technical parameters of the roof and your physical and technical capabilities - the ability to work for a long time at height and the availability of safety equipment.
Today, metal tile is one of the most common roofing materials, which has multiple advantages, such as low price, a light weight and durability. Despite the fact that the metal tiles are coated with a primer and anti-corrosion coating However, we are still talking about galvanized sheets. Of course, galvanized reliable material for arranging roofing, however, over time, it lends itself to corrosion. To protect the material, give it a decorative appeal and just change the color will help the paint for metal tiles Superdecor.

Application technology rubber paint After all the work on surface preparation has been carried out, proceed to painting. Possible various ways paint application: brush, roller, spray gun.
When using a spray gun, use a nozzle with a diameter of at least 2 mm. If the paint is too thick, then it must be diluted with SUPERGROUND-100 primer (no more than 5%). The principle of applying paint is the same as when using other paints.
Coloring must be done in at least 2 layers. Splashes of paint flying from the brush must be removed very quickly with a damp cloth, preventing them from drying out. If, after the paint has dried, unpainted areas are visible on the surface of the wall, then they can be eliminated by covering them with another layer of rubber paint.
