What are the walls primed with before puttying? Which primer is best for walls under putty? All mixtures are divided

Priming - technological process when preparing the surface for applying various finishing materials. This is carried out by coating with a primer - a special composition that provides:

  • strengthening surface layers;
  • decreased absorbency;
  • increasing the adhesion characteristics of the treated surface.

Certain types of materials help to increase protective properties against corrosion, prevent the development of rot or prevent the growth of mold and mildew.

Why do you need to prime walls before painting and puttying?

Coating walls with primer is one of the types preparatory operations, before the subsequent application of a putty or paint layer. The treated surface acquires a number of useful properties:

  1. The strength of the surface layers increases, the particles of the “chalking” wall structure are held together.
  2. The absorbency decreases, which helps reduce the consumption of liquid covering material.
  3. Adhesion to most finishing products increases: metal, wood, concrete, brick, etc.
  4. Prevents the penetration of moisture into the surface being treated, which, in turn, prevents the occurrence of dampness.
  5. The walls acquire antiseptic characteristics - mold does not form on them, fungus does not grow, and rot does not appear.

Types of primers

Impregnating compositions are divided according to purpose:

  • deep penetration(universal);
  • adhesive (cohesive):
  • pigmented (colored);
  • antiseptic.

Universal composition

It is a composition of water and group organic matter, - latex and acrylic. The state of aggregation is liquid, which allows it to penetrate into the structure of the surface being treated. When dried, organic compounds form a chain of copolymers in the form of a dense film.

Small solid particles, a “chalking”, dusty structure, stick together, and a single dense surface is obtained. In other words, a base is formed on which putty or paint composition fits well. In addition, it is convenient to apply to such a surface - the glue has good adhesion to organic impregnation.

By varying the composition of the primer for painting walls, you can enhance certain properties, that is, obtain a liquid with the ability to penetrate 5–10 cm deep into the surface, or form a dense structure covered with an organic film.

Adhesive compounds

One of the well-known representatives of this type is a composition under the general name “concrete contact”. Consists of organic copolymers, water and filler - fractional quartz sand. Has a number of advantages:

  • Can be used on many materials - concrete, brick, wood, paint and varnish coatings, putty, plaster;
  • forms a vapor- and moisture-proof coating;
  • creates a rough surface that has excellent adhesive properties.

Thanks to these characteristics, this type of impregnation has found application under tile adhesive, plaster and putty, including decorative coverings. For ease of use, color is added to the composition - this allows you to distinguish places where the primer has not been applied.

Pigmented composition

This type of coating, in addition to the properties of a universal primer, allows you to create the necessary color background on the surface. It's necessary:

  • uniform colors allow you to stick thin translucent wallpaper;
  • a light surface is needed when applying “liquid” wallpaper;
  • a uniform color background is included in the technological chain of applying various decorative coatings, for example, when applying “Venetian plaster”.

In addition, it allows you to apply light colors over dark base, - the primer “whitens” and brightens the base.

Antiseptic impregnation

This type is used in places where temperature changes are possible, there is high humidity. Such external factors contribute to the formation of mold, mildew, and organic material may begin to rot. Antiseptics can be used as independent compositions or they are introduced into traditional acrylic compositions.

The composition is applied to a previously prepared surface:

Since most types of primer are liquids with varying viscosities, application is carried out using paint rollers or brushes. Concrete contact is a paste-like consistency, so it is more convenient to use a spatula or a brush with hard bristles.

How long does it take for primer to dry before painting?

The drying time of the applied composition depends on the absorbency of the base and the type of composition. When using a universal type of impregnation on dense concrete in one pass, the duration will be 1–3 hours. The same composition, but on plaster or putty, will increase the time to 2–5 hours.

Concrete contact acquires its properties after 24–36 hours, depending on the base and thickness of the applied layer.

Which primer is better for puttying and painting?

The choice of type of impregnation for walls depends on the material being applied, the type and structure of the surface.

  1. Prime the walls before painting with water-based or acrylic paint. Before application water-based or acrylic compositions On concrete, plastered, puttied or previously painted surfaces with similar compounds, it is recommended to use liquid acrylic primers for painting.
  2. The same impregnating liquids can be used for putty, but the bases must be dense and have good adhesion to them. In the presence of paint coatings It is advisable to use concrete contact.
  3. Pigmented compounds used when leveling the general color background, - lightening the dark base. Suitable for paints and decorative coatings - wallpaper, plasters, putties.
  4. Antiseptic composition must be used, regardless of the coating used, in the presence of temperature changes and high humidity.

Primer cost

Average prices:

  • Concrete contact Cerezit CT-19 5 kg costs 410–480 rub/bucket;
  • Primer BRAVE BRIGADIER Betonkontakt 6 kg, 700–780 rub/bucket;
  • Latex primer for interior work Leningrad paints 10 kg, 950–990 rub/canister;
  • Latex primer for interior work Leningradskie paints 5 kg, 730–790 rub/canister;
  • Moisture protection primer concentrate 1: 7 TEKS Profi 0.9 kg, 150–1800 RUR/bottle;
  • Primer Capital, pigmented, white, for wallpaper, 1 kg, 155–200 rubles/canister.

To summarize the above, a primer is always necessary. This will create a strong, reliable coating on the walls that will last for decades.

Final leveling becomes a mandatory step, regardless of what materials are used in the production of walls, and it does not matter whether the surface is plastered. Ignoring this step leads to a damaged, ugly appearance walls Before moving on to the leveling itself, the walls must first be primed before puttying. But is treatment necessary?

A special layer of primer after finishing putty necessary to protect the final finish. The same question concerns the need for priming before puttying work. The use of each composition causes certain consequences. Studying information from the manufacturer will help you decide which materials are best suited. But the main advantages of priming are easy to highlight:

  • Each layer starting materials will hold on tighter;
  • The bases do not fall off or crack over the entire area;
  • The plastered wall becomes protected from deformation and fungi and mold.

Do I need to prime before applying putty? If you choose the right materials, then priming determines how high quality and durable they will be. renovation work basically. Each composition, with its properties, is suitable only for certain surfaces. All these materials are different from each other:

  • brickwork;
  • concrete blocks;
  • wood;
  • drywall.

The porosity and density of these materials are at different levels. However, the initial primer before plastering the walls increases strength in any case. The composition adds grip and solidity.

Benefits of using a primer

Modern primer for walls under putty has unique composition, which provides excellent adhesion to almost any materials. Plaster or putty holds up well with this processing method. But the main question is, what should come first - primer or putty? It is worth taking a closer look at the benefits for buyers from the use of materials, this will allow you to find the answer to the question of whether it is necessary to prime the walls before puttying.

  • A primer before filling walls ensures that gaps and cracks in the material are filled. This not only helps to increase adhesion. Material consumption per unit area is reduced. Compared to primers, putty mixtures are much more expensive. But when carrying out construction work, everyone usually tries to save money, which is also facilitated by the decision to prime between layers of putty.
  • People often have problems with old stained walls. Contamination appears again after finishing treatments or after they putty. Defects on the surface can disappear if you decide in time whether it is necessary to prime the putty before proceeding to painting .
  • In the case of preliminary priming on the walls, it is then easier to putty, because in the future the mixtures will spread faster on the surface that has previously gone through a special treatment. Whether it is necessary to prime after puttying is another question.
  • When applying putty, you can prevent biological threats of various types such as rot and fungi, and the appearance of other dangerous microorganisms.

Nothing to add. Even a newbie construction work it becomes clear whether the walls need to be primed after puttying. But remember that first you need to prime, only then putty or putty.

About the correct priming technology

Before applying a primer before plastering the walls, you need to make sure that all preparation steps have been completed. Otherwise, it will not be possible to achieve high results without additional costs. How to prime walls correctly? First you need to find out which ceiling primer is suitable in a particular case. It is better to find out in advance how to apply the material correctly and what tools are recommended.

Separately, we obtain information about how long it takes for the surface with the layer to dry. Then unsuccessful visual changes will not accompany the renovation. It’s easier to figure out how to prime the walls before puttying , than to correct the mistakes made later.

In the video: is it necessary to prime surfaces before puttying?

Types of surface primer

The primer mixture must be selected according to the base material. The answer to the question depends on this: is it necessary to prime between layers? For different surfaces it is necessary to use different mixtures. In modern industry, many primer compositions are recommended for use in different forms release. Already have ready-made options, but there is something that you still have to dissolve or mix yourself.

The material of the base, together with the walls, determines another equally important factor - this is the time after which the surface is puttied after the primer is applied. If you do not wait, you will not be able to achieve the desired result.

Universal mixtures

Most often we are talking about water-soluble acrylic putty compositions with a separate layer. They are universal and suitable for priming any surface, which has become the reason for their widespread use. This is how any finishing primer works. This is the best option for priming the following surfaces:

  • metal where painting is used;
  • wood;
  • foam concrete ceiling;
  • clay walls;
  • concrete blocks;
  • brickwork (in this case, priming the walls for putty will not be difficult).

Polystyrene and perchlorovinyl primer

Perchlorovinyl compounds can be immediately used for walls made of brick or cement plaster, which is used in advance. The material is also applied on top of the plaster itself. This is usually done before starting final finishing. But such a primer for putty is used more effectively for work on external walls. This species is toxic to human health.

Polystyrene is another substance that poses a danger to people until it completely shrinks. Users are advised to additionally protect themselves with goggles and gloves.

From phenol

This primer is the ideal accompaniment for:

  • plywood;
  • good fiberboard;

Wall putty also copes with plasterboard very, very well. It is convenient to continue after the applied mixture is ready (after 20-30 minutes). Is primer necessary at all? The answer is obvious.

Glypthal mixtures

This perfect option for coating wood, although this mixture can also be applied to metal, even painted. But it is better not to think about using this particular variety in domestic conditions, it is too harmful for humans. However, this information will help you figure out which primer is best for walls under putty, because not everything is equally useful for both humans and surfaces.

Alkyd mixtures for wood

The optimal solution for processing and painting wooden walls. Thanks to these compositions, there will be no need to worry about the premature appearance of rot. Puttying the walls also protects against this. You just need to prime consistently and carefully.

What primer to use before puttying ? When choosing, the information from the manufacturer on the packaging will serve as a guide. Usually it’s easy to find all the relevant recommendations there, including on primer and putty .

Preparation process

The sequence of actions will be as follows:

  1. Complete removal of dirt from walls. It is necessary to blow off the dust and get rid of adhering particles of the solution itself, and remove the old coating to the base.
  2. At high level Due to the humidity of the walls, drying is required before using the primer. It’s easier to use a hair dryer, otherwise you won’t achieve the desired result. Then it doesn’t matter what is used: putty, primer .
  3. Degreasing compounds will help get rid of greasy stains.

What primer should I use under putty and how to apply it? Previously, I myself was interested in this question, but now, having gained experience, I will try to answer it in detail. In addition, I will tell you how long it takes for the primer to dry, and I will also introduce you to other nuances of working with this material.

Why prime

Many people who are faced with renovating their home for the first time are interested in whether a primer is needed or can be done without it? After all, priming not only takes time, but also increases the cost of repair work.

  • Improves adhesion. Adhesion is the adhesion of materials to each other. If adhesion is poor, the putty will begin to peel off soon after hardening or will not adhere at all.

Accordingly, the better the adhesion, the stronger and longer the putty will last;

  • Strengthens the foundation. This quality is important for crumbling, loose surfaces;

  • Prevents mold growth. The soil usually contains an antiseptic that prevents fungus from developing on the treated surface.

As you can see, in principle you can putty without a primer. However, it is impossible to guarantee a high-quality result. Therefore, if you do not want to do the job twice, you should not refuse priming.

Types of primers

For priming walls before puttying in Lately polymer, often acrylic primers are used on water based. They cope with the task perfectly, in addition, they have the following positive qualities:

  • No smell. Due to the fact that these soils are water-based, they are environmentally friendly and practically odorless;
  • Fast drying. Since water evaporates quite quickly, the drying time of the primer can range from 2-3 to 12 hours, depending on the temperature and humidity of the environment.

Keep in mind that the soils in question come in several types:

Deep penetration

These compounds are designed to strengthen the surface. They penetrate deep into the structure of the base (up to 10 centimeters) and glue the pores together. In addition, they form a film on the surface, thereby reducing the consumption of finishing materials.

Therefore, deep penetration putties are used for porous and crumbling surfaces. In particular, it is recommended to use them before puttying old plaster.

All prices in the article are current in the summer of 2017.

Adhesive

The name of these primers speaks for itself - they are designed to improve adhesion between building materials. This quality is due to the presence of a fine abrasive in the liquid, due to which smooth surfaces become rough after treatment.

Price:

Universal

Universal primers have the properties of all the compositions described above - they improve adhesion and strengthen the base. It must be said that these compositions are the most common, since they can be applied to the following surfaces:

  • Plastered walls;
  • GCR-lined surfaces;
  • Putty walls, i.e. primer can be applied between layers of putty.

Universal primers can be applied not only to mineral substrates, but also to wood. The only thing, keep in mind that as a result of the presence of water in the composition, they lift the wood fibers. Of course, this doesn’t matter when putting putty, but before painting wooden surface will have to be sanded further.

This raises the question: what is the difference between a universal primer and an adhesive or deep penetration primer? And why do we need the latter at all, if you can use a universal composition?

The fact is that with adhesive primers and deep penetration compounds the effect is more pronounced, since they are narrowly targeted. Therefore, “universal” primers are called conditionally. In reality, they cannot replace, for example, adhesive primer.

Priming technology

Finally, let’s look at how to properly prime the surface with your own hands before filling. This operation includes 3 main stages:

The work is done like this:

Illustrations Description of actions

Surface preparation. Do not rush to prepare the primer, because first you need to tidy up the walls by following these steps:
  • If you putty cracks, they must first be widened;
  • Peeling areas of old plaster or paint must be removed;
  • Then the base must be cleaned of dust and dirt.

Soil preparation:
  • If the composition is purchased in the form of a concentrate, it must be diluted with water. Detailed information this procedure is contained in the instructions on the packaging;
  • Shake the liquid thoroughly;
  • Pour the primer into a flat container. It is most convenient to use a special cuvette for this.

Surface treatment:
  • Apply liquid evenly thin layer using a brush or roller. Make sure that the surface is processed completely, without gaps;
  • Wait until the liquid dries. I already mentioned how long it takes for the primer to dry before applying putty - on average 2-4 hours;
  • Treat the surface again and wait until it dries.

This procedure must be repeated after applying each layer of putty. This will create a durable and reliable coating on the surface of the walls.

This completes the priming.

Conclusion

Now you know what primer to use for putty and how to apply it correctly. Watch the additional video in this article. If you have any questions on the topic raised, you can contact me in the comments, and I will definitely answer you.

When renovating an apartment, a number of works are performed. Particular attention is paid here to plastering the walls. This stage is fundamental when decorating a room. Using putty it is created Smooth surface, which makes it possible to somewhat simplify finishing apartments.

Very often people forget about performing certain processes, including priming. Priming the walls before puttying can improve the quality of finishing work. Therefore, it is recommended to approach this work very carefully.

Why is wall priming so important?

The walls in an apartment or house are made of different material. So, it can be brick, concrete and other materials. Regardless of this, all structures are subject to careful preparation And finishing works. This process is very important, since the service life will depend on it finishing coating. When preparing the base for putty Special attention given to priming. Using special compounds adhesion can be improved.

Primer compositions have adhesive and fastening properties. This allows you to protect base layer from damage, especially from those that may occur when changing finishing materials.

With the help of a soil composition, they are created optimal conditions for uniform application and absorption of putty and other materials. Therefore, the primer is used not only before puttying, but also before applying the final finishing coating.

Many craftsmen who finish their own home often forget about the importance of such a process as priming and preparing walls with putty. As a result this leads to a decrease in strength and quality of finish. The absence of this process often leads to peeling, as well as the formation of spots, cracks and other defects on its surface. Priming the walls before puttingty will improve the quality of finishing work.

An important advantage of the primer for putty is that it helps reduce material consumption. So, we can sum it up and say that priming walls is important stage in the process of renovating the premises. It increases the strength of the connection between the putty and the wall, and also reduces its consumption. Therefore, you need to approach the work very carefully.

Primer selection

As it has been established, priming is an almost obligatory step in the renovation of a room. In order to achieve the desired result, you need to choose the right primer. When choosing a material, it is worth considering a number of factors. This applies to the material of the walls and their condition. When we're talking about about priming brick or concrete, then the best option will become a deep penetration solution.

To treat walls before puttying, you can use:


So, which primer is better for putty? On construction market big choice soil solutions, each material has its own scope of use and purpose. Therefore, this issue must be resolved first. It is worth noting that for priming walls under putty it is better to use deep penetration solutions.

On next stage needs to be decided financial issue. There is no need to skimp on preparing the base for putty. From this the quality and reliability of the future surface will depend. However, the costs must also be justified. Some primers have a high price, but are in no way inferior in effectiveness to their cheap counterparts.

How to apply primer

When priming walls special attention is paid to the method of applying the solution. In this process great value affects the condition of the surface, as well as the purpose of the work being carried out. The primer is used not only to improve wall adhesion, but also to prevent mold.

To apply the solution you will need:


How to prime walls

Primer and other work that is performed on preparatory stage, you can easily do it yourself. But for this you need to follow the established sequence of work.

Applying a primer for putty is carried out in a few simple steps:

  1. prepare work premises;
  2. clear the wall from dirt, dust and various defects;
  3. apply soil solution.

An important step is preparing the surface for priming. All defects and dirt are removed from the wall. During the application of plaster, splashes of solution may form on the surface. They must be carefully removed from the surface.

The surface is thoroughly cleaned of dust, which creates an invisible film. This film reduces the effectiveness of the sealant. Often, contamination of the base causes cracking of the putty.

Before you start directly priming the walls, you need to prepare the following tools and equipment:

  • the tool with which the solution will be applied (brush, roller or spray);
  • comfortable container for primer;
  • stepladder used to process top part walls;
  • rag and protective equipment.

The primer is applied to the wall in one or several layers, it all depends on the condition of the surface. You can begin applying putty only after the primer has completely dried.. This may take from several hours to half a day. So, if a quick-drying solution is used for work, then further finishing of the wall can begin after 5 hours. In other cases, the primer dries in about 12 hours.

Treating walls with a primer is an important and responsible process. You can do such work with your own hands, the main thing is to follow the technology and not rush.

Many people believe that priming walls before puttying is a completely optional procedure. However, is this really so, and is it worth saving on this material? We will answer this and other questions in the article.

Priming surfaces - waste or savings?

"Is it necessary before puttying?" – each specialist gives his own answer to this interesting question. To determine which one is correct, you need to carefully study the properties of the material. The fact is that, no matter what the walls of the building are made of, be it brick, wood or concrete, they will somehow have to be prepared for decorative design. It is for this purpose that a primer must be applied to their surface.

The fastening and adhesive properties of the material often prevent cracks that may form during dismantling old decoration. The primer composition helps to apply not only putty, but also wallpaper glue, plaster and paint more evenly to the surface. Thus, a primer before putty helps the specialist achieve best quality final finishing. Don’t forget that primer is an excellent antiseptic that prevents mold and mildew from forming on the surface of the walls of your home.

On the other hand, you don’t have to prime the walls before applying putty. However, this will sharply increase the likelihood that the repair will be done poorly. Due to the lack of intermediate adhesive material, the wallpaper will peel off from the walls after a short period, and the putty will begin to fall off. The paint will suffer no less from this - due to the lack of primer, it will crack and fall off the walls.

Which composition should you prefer?

Having figured out whether it is necessary to prime before, let's find out what types of materials there are. Every experienced builder knows that plaster, concrete or brick have varying degrees of porosity and absorb moisture in their own way. It is this characteristic that plays a decisive role when choosing a primer. More dense substrates are treated with compounds with increased adhesion. Plastering walls from less dense materials performed using a deep penetration primer. As a rule, the third type of materials with average density is coated with a universal putty primer.

Depending on the composition, priming materials are divided into the following types:

  • acrylic:
  • alkyd;
  • glyphthalic;
  • polyvinyl acetate;
  • perchlorovinyl;
  • polystyrene;
  • phenol based primer.

This or that material has different properties and shows itself differently when working with the same concrete or brick. In addition, before priming the walls before puttying, you should make sure that the composition is suitable for wallpapering or painting walls.

We select a primer depending on the wall material and finishing

Acrylic primer is included in the list universal compounds. She can use on various surfaces, starting from wood and ending with concrete. Among its properties, it is worth noting its good penetrating ability, which is why it is often used on plastered walls. This primer significantly increases the adhesion of any porous building material. However, this composition is not used for metal surfaces, as it promotes corrosion. This material dries 5–6 hours after application. It is widely used before decorating walls with wallpaper and painting.

Alkyd primer for walls under putty is used exclusively for application on wooden bases. However, it can be used for any type of finishing. After treating wood surfaces with this composition, a swollen structure is obtained, and their adhesion to finishing materials increases several times. This primer is well suited for working in residential buildings. The material dries completely within 9–12 hours after application, provided that the room temperature does not fall below 20 °C.

Glypthal type primer is used to treat surfaces in dry rooms. It is optimally suited for application to metal substrates. At a temperature of 20–23 °C, the composition dries within a day. It provides good surface adhesion to all known materials. Polyvinyl acetate primer consists of latex and is used to prepare surfaces on which polyvinyl acetate paints will be applied in the future. This primer dries within 30 minutes after application.

Perchlorovinyl compounds are useful for preparing any surfaces, including metal ones. However, due to the presence of strong toxins in the composition, it is not recommended to apply this material in residential areas. This primer dries within 1 hour. Polystyrene compounds are often used to treat wooden and plastered substrates. But, as in the previous type of primer, polystyrene materials contain a large number of toxins. In this regard, their use in living rooms unacceptable. These compounds dry within 12 hours after application.

Phenolic primers are used to prepare wooden and metal surfaces. They are not used in residential buildings, as they contain highly toxic substances. These primers dry in 12 hours.

Application of material - algorithm in detail

After we have finally figured out that priming, as well as puttying the walls, is a mandatory activity, it’s worth learning how to prime the surface yourself. To work, you will definitely need a tray or other convenient container into which you can pour the composition. For application, you also need to buy a brush with small bristles or a narrow roller. Other tools you will need include a sponge, a bucket, protective gloves and goggles. If you work with toxic compounds, be sure to wear a mask.

After you have cleaned the base of all excess, you will need to remove any remaining dust from the surfaces. To do this, the walls need to be washed with a damp sponge. After this, pour the primer into a container, dip a roller into it and apply the composition to the wall. It is much more convenient to use a roller for work, since with it the primer will lie on the surface more evenly, and there will be no lint left on the wall.

A very important factor when working is the thickness of the material layer. Whenever you apply the composition to the base, you should make sure that its parts do not accumulate in one place, and also that no drips remain on the wall. The material should be applied consistently. Start by moving the roller downwards, then do the same from side to side. It is quite difficult to treat the most inaccessible areas with a roller, so it is better to use a brush to work in corners.

Once you have finished applying the material, leave the surface to dry completely. In most cases, formulation manufacturers indicate the time and conditions required for their products to dry. The time it takes for the composition to dry is significantly affected by the level of humidity and the thickness of the layer you apply. In any case, before applying putty, you should make sure completely dry primers. To do this, run your hand over the surface. If there are no white marks on your hand, then the base is ready for further work.

Brands of primers - what compositions are popular among buyers?

Primer manufacturers offer many options that can be used to treat concrete, brick or wood. Modern experts easily determine exactly the composition that is suitable for certain purposes. However, it is difficult for an inexperienced person to choose good material not overpriced. Let's look at the most popular options that easily cope with their tasks, and their purchase will not put a big dent in your wallet.

Famous company Knauf offers customers excellent and inexpensive option– primer Tiefengrund. This composition has good adhesion, it dries quickly and significantly strengthens the base. The cost of a bag of material is from 150 rubles. Another company whose name is known even to people far from construction is Tikkurila, offers three mixtures at once: Luya, Otex And Euro Primer. The first material has antiseptic properties and is excellent for working in rooms with high humidity.

The second is produced on an alkyd base, increases the adhesion of surfaces and is used for working with problematic surfaces. It is indispensable in cases where there are cracks and other damage on the walls. The third composition is characterized by quick drying, base-strengthening properties and antiseptic components. The cost of all three materials ranges from 120 to 200 rubles.

A lesser known primer manufacturer is Bergauf– recommends buying the composition Tiefgrunt. This material is worthy of attention due to its efficiency and versatility. It increases the adhesion of surfaces and quickly fills cracks in the wall. The price for a bag of primer is from 150 rubles. Another a good optionCeresit CT 17. This primer universal type used in dry and damp areas. It has antiseptic and strengthening properties. Cost – from 100 rubles. per package.
