Do you need to prime the surface before painting the walls? Pretreatment before painting. Is it always good to save

If the house is being renovated, and the chosen design involves painting the walls and ceiling, then surfaces should be primed before finishing work. However, many are not convinced that this is necessary. Why do I need a primer before painting?

If you are in doubt whether it is necessary to prime the walls before painting, we answer - you need to! You just need to approach the matter wisely, having studied the pre-purchased paint. In order for our future paint to adhere well to the surface, it is necessary to improve the adhesive properties of the surface. If you improve the adhesion of the surface of the wall, ceiling with finishing material, the paint will stay on the surface longer.

Priming the walls before painting is necessary in order to:

• improve the structure of the base;
• reduce moisture absorption;
• use paint sparingly.

The paint will lie on the primer more evenly, absorb less, therefore, it will be needed less. One layer of staining will be enough - concrete or plastered walls will not shine through the painted surface. Do I need to prime the ceiling before painting? If you decide that painting the ceiling is the best option for finishing, then yes. But here it is worth considering many factors - from the type of surface to the operational characteristics of the room.

Primer types

The primer can be used not only to improve the adhesive properties of the treated surface. If you apply a certain composition, then you can protect the walls or ceiling from various negative influences. Therefore, today specific types of primer mixtures are on sale.

By appointment

There are several types of soils for their intended purpose:

• Adhesive - needed to improve adhesion between the base - wall, ceiling and coloring composition.

• Antiseptic- used to protect surfaces from mold, bacteria, fungi.

• Flame retardant - fireproof soils.

• Water repellent– protecting surfaces from moisture, corrosion.

• - they are used in preparation for painting loose, porous walls.

Some primers are universal - they have several properties at once.

Composition

According to the composition, primer mixtures are divided into:

• mineral;

• acrylic;

• alkyd;

• universal.

The initial surface treatment is carried out with mineral quick-drying primers. They level the brick, concrete base for subsequent painting. Mineral-based primer fits well on plastered wall surfaces.

In addition to mineral primers, there are alkyd-based primers. They are suitable for wooden, painted surfaces, suitable for fiberboard, chipboard, ceramic tiles, glass, increase their strength for better adhesion to paint.

On the video: types of primers.

Acrylic primers

The advantages of this type of soil are that they are odorless, and dry in just a couple of hours. Therefore, it is convenient to use them in small rooms, living rooms, if repair work in one room has to be combined with living in others.

Acrylic composition is easily applied to different surfaces:

• concrete;
• wooden;
• asbestos-cement;
• plastered.

Often such compositions are used when preparing walls for wallpapering - they are applied with a roller or brush. Acrylic primer is easy to use - when thickened, it is enough to dilute it with water, and it is ready for use again.

Disadvantages of acrylic primer - it is not able to protect metal surfaces from corrosion, rust, therefore, other compositions are chosen for metal priming.

Alkyd primers

This type of primer for metal surfaces is just right. Alkyd compounds also perform a protective function - they do not give rust the slightest chance, not the slightest opportunity to damage the metal roof and other surfaces made of cast iron, metal. Therefore, they must process pipes, reinforced concrete structures, containers made of metal, mechanisms and parts of transport.

Alkyd primer is suitable for loose, porous wood, it protects it from swelling, preparing the surface for subsequent coating with coloring compositions.

Alkyd compounds protect wood from mold and decay, so they are often used in facade work for processing wooden walls, frames, doors, and platbands. They dry quickly, fill pores and smooth surfaces. Impregnations based on alkyd and linseed oil have the best qualities.

Such compositions are needed where the coatings are old, dilapidated, therefore they are strengthened with primers that not only impregnate, but also have an adhesive property, strengthen the surface before painting.

In the building materials market, primer-putty is in demand - thicker than ordinary soil, the composition fills the smallest cracks and pores on the wall, strengthening it and at the same time leveling it. This speeds up the process of preparing the walls for painting, because instead of two operations, it is enough to carry out one.

Hydrophobic primers also reinforce old wall surfaces, preventing condensation and moisture from penetrating into the surface.

Betonokontakt

This composition, containing cement and quartz or marble sand, is used to treat concrete bases, hence the name. The smallest dust (marble, quartz) makes the surface rough, which improves the adhesion properties of concrete with coloring compositions. Betonokontakt is used as a primary treatment, the walls are plastered over the primer.

There are the following types of concrete contact:

• based on acrylic;
• silicone based.

Acrylic composition for concrete is used for interior work, and silicone, which is more durable, is used for exterior work when finishing facades. It is toxic, so when using it, you must use protective equipment and follow safety precautions.

Silicone concrete contact forms a super-resistant coating, has high vapor permeability, allowing the wall to breathe. Due to toxicity, it is practically not used for interior work, especially in residential areas, but it is suitable for working on any mineral bases - brick, drywall. On top of such a primer, only silicone plasters and paints can be used.

Mineral primers

Such primers are well suited for ceiling surfaces - they contain gypsum, lime, dry quickly enough - after application, paint work can be carried out in just a couple of hours.

Additional Information

Doubts about whether it is necessary to prime the ceiling before painting, overcome many home craftsmen. On the one hand, who will pay attention to it - is the paint evenly lying? On the other hand, if a piece of paint or plaster falls, it is unlikely that someone from the household will like it, and even the master himself.

However, not every wall needs to be primed. Indeed, why primer when it comes to storage and other utility rooms? For walls with a solid base that does not absorb moisture, with good adhesion - is a primer needed? Perhaps you can do without it.

In other cases, especially when it comes to living quarters that you want to finish with high quality, painting or wallpapering, it is better to carry out preliminary work. Before priming, carefully read the instructions on the package, if you need to dilute the composition - dilute.

The primer can be one-component - then only water is added, or two-component - in addition to water, a hardener is also needed.

The process of priming the walls does not take much time. And when you admire the results of your work and an evenly painted wall, you will understand why the walls were primed before painting.

Any novice master may wonder whether it is necessary to prime the ceiling before painting. Further, another topical topic for conversation is whether it is necessary to prime the ceiling skirting boards. In general, how to properly prime the ceiling? Let us consider in detail all these issues so that in the future there are no annoying mistakes.

It should be noted right away that all work of this level is done exclusively by hand, so you don’t have to worry about the cost of procedures.

Primer - what functions does it perform

A perfectly reasonable question that can arise in the mind of any person is why do we need a primer at all? The purpose of this procedure is to prepare the ceiling or any other surface for further finishing work. Such works can be: painting, and much more.

This repair operation performs a very important function - protective:

1. The surface acquires additional strength, its layers are impregnated and glued together;
2. Moreover, the surface becomes more moisture resistant after applying the primer. At the same time, she does not lose her ability to “breathe”;
3. The consumption of paint or other decorative and finishing materials is significantly reduced - if the work is carried out on a surface that has been primed. That is, to the question: "Do I need to prime the ceiling" the answer will be unambiguous - of course, it is necessary.

Liquid paint instead of primer - is it acceptable

In certain situations, when performing construction work, not a primer is used, but paint.

The paint in this situation is pre-diluted in such a way that the composition is as liquid as possible. Many people ask the question - is it even possible to do this, if it makes any sense?

First of all, when the paint is liquid, it not only impregnates well, but also remarkably compacts the surface - no worse than primers created specifically for this. But this is only that small part of the "iceberg" that you can see with the naked eye. And if we consider the process in more detail?

Liquid paint, in fact, has in its composition many large particles of fillers, solvents - they are part of the material. It is because of this that the paint will only interact with the top layer of your surface. At the same time, it will certainly seal all micropores, it will not penetrate inside under any conditions. That is, it is better not to prime the surface with paint - no specialist will recommend this.

What is the best primer

Comparing a primer and any paint is not entirely correct. The primer is a very fine suspension of polymer resins and that says it all.

What else can be said about the primer:

• Deep penetration compounds fall into the very thickness of the material being processed. Further, polymerization occurs - and the layers of the processed material stick together;
• The microparticles of the substance are approximately 10 times smaller than the paint particles. They have a very high permeability - this figure is even higher than that of high-quality drinking water.

Thus, we figured out - liquid paint is not at all suitable for the role of soil. Moreover - in order to prime the surface of the ceiling. The top layer of paint is able to glue - but this will not add strength, it will simply form a thin film, which will definitely not give reliable support to all subsequent layers (including decorative ones).

Do you need a ceiling primer at all?

There are people who do not prime the surface. In fact, this is not always the right decision. Consider the factors who speak in favor of the primer:

• Regardless of what the ceiling is finished with, your finish is bound to be subject to downward pressure. She also bears a heavy burden on herself. Because of this, over time, the base of the ceiling, which was not primed, will crumble, shedding will occur - even if your ceiling is pasted over with ceiling tiles using high quality glue;
• The durability and strength of the ceiling coating depends directly on the adhesion of the ceiling surface and paint or some other coating. The primer gives your surface this property ideally.

Dust and loose particles

Repair or construction work is a rather dirty process. During such activities, there is always a mass of dust. Even when you move into a new apartment, the renovation of which has already been completed, you have to do the cleaning - not once or twice. Only after that the building dust disappears.

During finishing work, it is impossible to remove all the dust - even if a powerful vacuum cleaner is used for this. The ceiling surface is no exception, here dust particles also necessarily settle.

When they are between the surface of the ceiling and the paint, the level of adhesion decreases - which does not affect the quality of the coating in the best way. Putty, paint, glue will hardly be able to cope with such dust.

As a result of this phenomenon, the ceiling finish may begin to peel off quickly - and this is due to small particles that are not fixed. Should the ceiling be primed before painting in this case? Of course, it is better to do such work - in order to protect yourself from possible problems in the future.

How to prime a ceiling

This is not to say that this issue is too complex. But, the work is carried out in several stages, each of which is quite important. We will understand this process in more detail - how should a primer be applied to the ceiling.

Preparatory work

First of all, you need to prepare the surface. This is where almost any finishing work begins. If you do not prepare, it is unlikely that you will get a strong enough grip - that is, the coating will not be able to hold out for a long time.

The preparation goes something like this:

• First you need to carefully inspect the work surface. The old coating is dismantled. If wallpaper was previously applied, there may be problems with their removal, but everything is solved easily if you approach the matter wisely;
• If you need to remove the plaster - pay attention to its degree of delamination. If defects are already visible, simply knock down the layers with a hammer and chisel;
• If paint has been applied, you can easily remove it. In this work, a metal brush is used - a very effective tool.

If there is old plaster on the surface and it is already crumbling, it must be removed exactly. In this situation, even deep penetration soil will not help - adhesion will be minimal.

• When the layer with the old coating is removed, the surface will not be even at all. It will have to be puttyed. It is necessary to apply the appropriate substance and wait - when everything dries completely.

We apply a primer

Before starting this work, you should carefully study the instructions - they usually indicate the consumption of material (primer) for each square meter of surface. The time for which the composition dries is also usually noted there. This is very important, because depending on the type of primer, these parameters can vary dramatically.

In detail, the application process looks like this:

• First of all, it is necessary to dedust the surface - this is done in advance. A vacuum cleaner or a brush will help in such work;
• Then they begin to apply a primer - the main thing during work is to make sure that there are no unprimed sections of the ceiling left. A spray gun is the perfect tool for this job;
• However, if you do not have this at hand, you can always use a roller.

It is not advised to use brushes for applying a primer - they leave noticeable traces, which are then not so easy to hide even under a layer of paint.

• Porous surfaces sometimes need a double coat of primer. For example, this will have to be done with a sanded ceiling or with a putty. In this situation, you also have to wait - when each of the layers of the primer dries out, only then work continues
• When working with a primer, be sure to use a respirator and gloves - for protection. No one is immune from allergic reactions when working with any chemicals.

Which primer is better - choose the type

There are a lot of types of primer today - choosing the best one is not always easy. You should focus on the purpose of the application, as well as on the surface that you are going to process in the near future. You can purchase primers of a universal nature - they can be used for any surface.

Some specialized soil is used only for a specific purpose. For example, these are primers for the floor, ceiling, for rough finishing. You can also write an antifungal primer here. And now let's take a closer look - what is the best way to prime the ceiling before painting.

Here everything is as follows:

• Usually, mineral-based primers are tried to be used to treat ceilings before painting. They contain cement - an excellent binder. Such primers are used on brick, concrete, silicate surfaces - for the purpose of rough finishing;
• Primers with an alkyd base - this tool is universal, great for wood products. Moreover, this primer is also used for application to chipboard, fiberboard, glass, galvanization are treated with it;
• Special primer designed for wood - perfectly preserves the surface from fungus and moisture, paint consumption will decrease due to its use;
• Acrylic based primers are famous for their excellent adhesive properties - this applies to any surface. This soil is universal. Concrete, brick, putty, plaster, drywall - this is not the whole list of materials on which acrylic primer will ideally fall. Because of this, these primers are in great demand today;
• Primers for metal surfaces resemble paint in their appearance, such substances create all the conditions for maximum adhesion to metal. These are specialty primers.

Be sure to watch the video on how the primer is applied before painting the ceiling - this will save you from common mistakes.

Results

It is not worth saving on a primer, as well as abandoning this type of work. In terms of finances, this still will not justify itself, there will also be costs to fix various problems with the ceiling surface.

The secret is to choose a specialized primer for your ceiling or one that has a mineral base. Often, universal primers are used for ceilings. It is important to study the instructions carefully, buy the product that will fit the surface. Already on the spot, it is usually decided whether to prime the ceiling plinth. It is better to just remove it - if it is removed easily.

The primer is a preparatory coating before painting the walls. After priming, the paint lays on the surface better, resulting in a perfectly even coating. However, some do not use primer, but immediately proceed to painting. Let's find out how much the primer of the walls is really necessary before painting, whether it can be abandoned and how to prime the surface in accordance with all the rules.

Advantages of priming walls before painting

Do I need to prime the walls before painting and can I do without it? The thing is that it is possible, in general, to get by, but it is highly undesirable. Getting to know the properties of a primer and the effect it can achieve will help you understand why prime your walls before applying paint.

• The primer strengthens the surface, penetrating deep into its structure.
• Levels the base, fills in small cracks and pores that exist on the surface, thereby reducing paint consumption during the painting process.
• By priming the wall, you seem to cover it with a thin film, on which the paint fits well, leaving no stains or streaks. If the primer lay down in a thin, even layer, then the paint will also lie well.
• Primers come in a variety of colors, you can choose a primer to match the color of the paint to make it brighter.
• For a damp room, such as a bathroom, you can purchase an antiseptic primer. It protects the walls from. After priming, the painted surface will be reliably protected from these troubles.
• Without pre-coating, the paint can crack, and if you want to repaint it, then in the process it will lag behind the putty.

Primer types

The primer must be selected based on the type of surface, area and manufacturer. If you need to cover a small area, then you can buy an aerosol can, it is more convenient to use.

It is worth buying funds for repairs in a hardware store, after consulting with a qualified seller. A well-known manufacturer is an additional plus, it can guarantee a good result. Before buying, check the expiration date and the appearance of the package.

Primer base

Most often, the walls are leveled with putty. Some believe that it can not be primed, because the putty surface is already a good preparatory layer for paint. But he has drawbacks: he can crumble, besides, he absorbs too much coloring composition. The primer will strengthen the base and save paint.

Wallpapers for painting do not require priming, as they are designed to apply a coloring agent.

Walls must be primed before wallpapering. The soil will provide a reliable connection of this layer with the walls.

Drywall should be primed in two stages. First, you need to cover the sheets immediately after installation. Secondly, the final finish with putty is also covered with primer.

Many people wonder if each coat of paint needs to be primed. If you are painting a wall over an old layer, then the primer must be used with different paint colors. It creates a barrier between two layers of paint so that the top layer does not show through.

How to prime a wall?

Priming technology is different for different types of soil. If you decide to apply it to the walls or ceiling, read the coating instructions for the type of primer you have chosen.

Remember that before applying water-based paint, it is necessary to prime the walls.

Instruments:

• Protective mask and gloves.
• Roller or brush.
• Pallet.
• Degreaser.

Primers are designed to increase the adhesion (adhesion) of the decorative finish to the surface for more durable fastening. In addition, priming reduces the absorbency of the wall, which reduces paint consumption. Further in the article are examples of the phased work on the priming of different surfaces.

Priming walls before painting

The process of applying a primer precedes and is an important preparatory step for wall decoration.

The solution is designed to protect, strengthen and level the surface, as well as improve the subsequent adhesion of finishing materials.

In addition, a special primer mixture can provide protection against mold or mildew.

What is a primer

Primer - the process of applying a special composition to the walls, performed before the start of finishing work. Priming walls for painting, wallpaper, decorative plaster, ceramic tiles.

Do I need to prime before painting?

The primer can be carried out with various compositions: paint, ready-made primer or concentrate, which is diluted according to the instructions. Also, the solutions are marked relative to the surface to which they will be applied (wood, metal, plaster).

water emulsion

- not the cheapest finishing material, so pre-priming the walls will significantly save on paint consumption.

The primer applied under the water-based paint reduces the hygroscopicity of the base, which leads to a more uniform distribution of the paint on the surface, increased coating strength, and increased wear life.

The primer for the water-based emulsion is applied with a brush, preferably in one layer, which should ideally cover all the irregularities of the wall, but at the same time not form uneven accumulations of soil. After complete drying of the primer composition, which takes 5-7 hours, water-based paint is applied in two layers.

silicate

Silicate paints are sold in dry form, for coloring the mixture must be diluted with water and used as soon as possible until the paint has lost its properties. Therefore, a silicate-based pre-primer is of great importance for the speed and quality of painting.

Special primers reduce the toxicity of the alkali contained in silicate paints and strengthen mineral surfaces to extend the life of the paint up to 10-15 years.

Acrylic

Priming before acrylic painting has an important feature: the composition must be applied to highly abrasive surfaces, it will gradually slip from smooth surfaces even with paint.

Therefore, before applying the primer, the surface of the wall must be treated with a stiff brush or coarse sandpaper in order to artificially create grooves and roughness.

In turn, the primer perfectly fixes the coating particles, leveling the adhesion and absorbency of the wall, which allows the acrylic paint to lay down in a uniform and durable layer.

Oily

Oil paint is one of the most highly adhesive, even without a primer coat. Priming increases the strength of the oil coating, making it smoother and less porous. However, often applied without a primer composition, it itself acts as an unsurpassed material for finishing work, as it adheres well to the surface.

When applying oil paint for the first time, the use of a primer solution is optional. With a secondary one, it is worth making a choice in favor of a special composition “on top of the paint”, which will save the time required to remove the old layer.

What to prime: popular options for primers for different surfaces

Priming compositions differ in the type of surface for which they are intended:

• For wood and metal. Alkyd and aluminum primers are used, which have anti-corrosion properties and provide strong adhesion of the finish to the base.
• For concrete. Epoxy primers are best suited, resistant to cracks and chips due to their high resin content. Used for subsequent painting, laying tiles, linoleum flooring.
• For brick. It is worth choosing a silicate primer, as it is the most resistant to natural influences and is suitable for processing facades, balconies or bathrooms.
• For polyvinyl acetate paint. The primer of the same name has a narrow specialization, allowing the paint to dry faster and better adhere to the surface.

A universal primer made on an acrylic base can strengthen and protect surfaces made of wood, concrete, ceramics, plaster and putty.

How to prime

The priming process can be divided into preparatory and main stages:

1. When preparing, it is necessary to grind the surface, remove dust, dirt, mold from it. If necessary, dictated by the instructions for the primer composition, the wall must be degreased: for this, acetone or similar solvents are used. During preparatory work, it is important to observe the correct ventilation of the room and the temperature regime within 5-25 ° C.
2. The main stage of priming is to dilute the required amount of the composition and apply it to the walls.

How many times

The primer is usually applied in two layers, the first of which is thicker, and the second is necessary to better strengthen the surface. It is important to dry each layer of primer for the time recommended on the package (usually several hours).

How to prime

Depending on the porosity of the wall, it can be primed with a brush or roller.

Each method has its own advantages.

The brush allows you to work through non-plastered surfaces, while the roller gives a uniform, streak-free layer, which consumes less soil.

How long can you paint

The minimum drying time for the primer must be found in the instructions for the specific composition, it usually ranges from 4 hours.

If the repair work allows, then it will not be superfluous to let the primer soak during the day.

In addition, if the primer composition was applied to plaster or putty, then subsequent painting should be carried out only after all layers of the finish have completely dried.

Drying of the primer can be slowed down by open containers filled with water in the room, so it is better to remove buckets of water, remnants of diluted soil and other liquids from the room.

Is it possible to paint without a primer

When can

When not to

• A primer is necessary when wallpapering for reliable adhesion to the walls.
• When using drywall in the finish. The sheets are coated twice: immediately after installation, and after the paint has dried for better fixing.
• When repainting an old layer of paint with a new color. In this case, the primer allows you to neutralize the translucence of the old finish.

The basis of the qualitative result of finishing work is the use of funds from one manufacturer. This helps to avoid unpredictable chemical reactions of different compositions. In addition, the product lines of one company are designed for cumulative use, which allows you to get the planned shade and structure of the coating.

It is obligatory to observe the principle of a stronger base in relation to the applied paint coating. This means that the primer layer should take over the functions of leveling and adhesion to the wall, and the selected paint will only have a decorative function.

Often, beginners who cannot determine whether a primer is needed in principle turn to professional help. To identify the need to use primers, professionals conduct a very simple test - you need to rub the wall with your finger: if a trace remains, then you cannot do without a primer before painting.

The primer of any surface is a stage that works to facilitate the progress of further finishing work. Modern primer compositions are able to strengthen the wall, protect it from destruction, cracks, chips, rust. After applying the primer, the paint layer is much better distributed, which reduces the consumption of the paint coating.

The ceiling and the quality of its finishes are somewhat similar to the role of a bassist in a musical group - if he does everything right, then you don’t notice him, and if he makes a mistake, then it’s immediately noticeable.

So, many do not notice the ceiling finish while it is done well, but if there are flaws, then it immediately becomes clear - in bright light, all the bumps and roughness are visible that appeared during the renovation. So, priming the ceiling before painting helps to make it even and beautiful. Although, some still doubt whether to prime the ceiling before painting, hoping to save money.

The question of whether it is necessary to prime the ceiling before painting with water-based paint can not even be considered - definitely worth it. Naturally, cases are different, but most repair specialists strongly recommend preparing the surface in this way. There are many reasons for this:

1. The primer increases the adhesion between the surface and the paint, which means there is less chance that the ceiling layer will begin to peel off.
2. With the help of a primer, you can, albeit a little, level the surface, getting rid of small flaws during the initial leveling.
3. The primer for the ceiling for painting guarantees an even application of paint, and hence uniform drying.
4. The use of a primer makes it possible to ignore possible differences in the material of the surface to be painted. For example, old and new putty from different companies may behave differently.
5. Current mixtures can reduce the risk of mold or mildew, and therefore help maintain your health.
6. Even if the surface is already covered with plaster, it is worth taking care of the primer. Since plaster absorbs liquids well, much more paint will be used up.

Now on the market there are also such types of paint that allow you to apply it immediately, over the old layer. Such compositions are good enough, but only if we are talking about a small cosmetic repairs- in other cases, it is best to do everything from scratch.

Important! If the ceiling is primed before painting, this will reduce the smell of the paint while it dries - some of the substances will be absorbed into the primer.

General information about the process

There are certain conditions regarding the preparation for how to prime the ceiling before painting. However, these tips, to some extent, are also true for preparing other surfaces for painting, regardless of whether the work is planned indoors or outdoors.

Surface preparation

If the surface is covered with tiles or wallpaper, then they must be removed using a spatula or drill, and the remaining glue must be washed off. In the event that a simple whitewash is applied, then you can wash it off with water, after which, using a spatula, remove a layer of plaster. To do this, use a wet roller or brush, and the plaster can be removed with a spatula.

In some cases, you can not remove all the plaster, limiting yourself only to those places where it began to peel off. In the future, these places will need to be leveled.

Attention! If in doubt whether it is necessary to prime the ceiling before painting over the old paint, then this is necessary if the previous layer consists of water-based paint, and the new color will differ from the old one. If it is nitro enamel, then it needs to be sanded, and then ground is applied - this way the new color will last longer.

Ground application

After finishing the preparation, you can start applying priming. The primer of ceilings before painting has a number of features. For example, before applying the first layer, it is worth wiping the surface with a damp cloth to remove dust or chalk that may have settled there. The same should be done after the first coat of primer has dried. This is done so that both the primer and the paint lie evenly, without forming bumps and streaks.

The process of priming the ceiling for water-based paint practically does not differ from the usual one, with the exception of those cases that have already been described above.

Advice. Remember to ventilate the area and also wear a respirator - some types of paints and primers can be toxic while they dry.

The only thing worth noting is Each type of surface has its own type of primer.. Some are suitable for concrete, others for wood, and others for bare brick. Therefore, it is worth carefully studying the description of a particular product in order to choose exactly the soil that is needed in your case.

In addition to the above, if you decide to do the repairs yourself, there are a number of tips that will help you avoid some of the problems and simplify the work process:

• After applying the first layer, it makes sense to walk over its surface with a roller again. So you can roll out possible drops and influxes.
• It makes sense to spend money and buy immediately quality rollers with interchangeable nozzles. It's also a good idea to buy a roller extension - there won't be a need to use trestle or tables to finish the ceiling. It would be useful to purchase a tray for rollers - with its help you can get rid of excess material, and then it will come in handy for working with paint.
• If several levels are planned, then before painting the ceiling you need prime all surfaces, including vertical ones.
• Before applying the final layer, it is worth remove all construction debris which can be dusty. As mentioned above - dust can settle on a wet surface and interfere with the application of paint, creating unpleasant looking stains and bumps. In addition, dust can settle on fresh paint, which can also spoil the appearance of the surface.

Answers to frequently asked questions

Do I need to prime the surface before painting the ceiling? Is it necessary?

No, primer is not required. Although, its use helps to save a little on materials and simplify the process of applying paint.

How long does the primer dry before painting the ceiling?

On average, it dries in two hours, no less. It all depends on the type of primer and environmental conditions. For example, on a cloudy day, drying can take a very long time, up to eight hours.

Do I need to prime the ceiling before painting with water-based paint?

Yes, it is better to do this, especially if there is no old layer of paint, only putty.

How to prime the ceiling before painting with water-based paint?

For these types of paint, there are special types of primers that are diluted with water. However, in some cases, the manufacturer may indicate that the use of a specialized solvent is necessary. The choice of such materials is quite wide and they are united by the fact that they do not give a sharp chemical odor.

To what state should the primer be diluted?

The best option is to the thickness of the paint you will be using. Too thick a mass can lie unevenly, leaving stripes along the width of the roller, and too liquid will drip onto the floor, and it will take much longer to dry.

How many layers is best to apply? How?

The best option, if you are not constrained in funds, is three layers, plus the final one. Each layer is applied across the previous one, so most possible blemishes can be corrected and streaks can be prevented.

Cracks formed during application, what should I do?

Wait until the layer dries and apply a new one that will cover the cracks.

How many times should a ceiling be primed before painting?

Usually one rough layer is applied and one final layer, on which paint is already applied. Although, as practice shows, it is better not to be greedy and apply several layers.

And so, many novice specialists ask themselves the same question, is it necessary to prime the ceiling before painting and puttying. Does it matter if a primer is needed? Let's find out the answer by watching the video:

So, should the ceiling be primed before painting? Need! Even if we are talking about whether a primer is needed for the ceiling to be painted with water-based paint, the answer will also be positive - this will help to achieve the best results. Even if you follow only the tips above, you will be fine with the repair.

However, if you doubt your abilities, then it is better to trust a professional team of repairmen who will help you repair an apartment for a relatively small amount.
