For which the primer of deep penetration is used - 3 types of soil for finishing works

Planning to perform painting works and do not know which primer deep penetration is best suited for your situation? I will describe various types of primer compositions, and I will tell you which one should be used in each case.

What is penetrating primer

The primer of deep penetration is an aqueous emulsion of polymer acrylic resins in a complex with modifying additives and auxiliary additives. Accurate quantitative and qualitative composition depends on what kind of primer needs.

Below I will tell you from which the penetrating soil consists, and I will describe the basic functions of all components:

1. Water - The basis of any penetrating primer:

• Water molecules are small, so it is well absorbed into any porous materials;
• Water also serves as a diluent, so if you use the primer concentrate, it can be diluted only with clean cold water.

1. Polymeric resins - binder based on acrylic resins. The main technical characteristics of the soil depend on its concentration in the emulsion:

• As the material penetrates the material, the primer fills all emptiness, pores and small cracks;
• After evaporation of water, the resin particles glued together, and strengthen the surface layer of the material;
• A thin capture of frozen resin remains on the surface, which provides high adhesion and serves as a good basis for applying finishing materials.

1. Surfactants (surfactants) - Part of all types of penetrating soil:

• Designed for degreasing surfaces and reduce surface tension of water;
• As a result, it is well enveloped solid particles and deeply penetrates the material.

1. Synthetic or Natural Latex - increases the elasticity of the polymer composition and improves the adhesion of small-scale building materials;
2. Silicone resins - have high waterproof properties and give the treated surfaces good moisture and dirt-repellent qualities;
3. Fungicides and antiseptic drugs - inhibit the biological activity of living organisms. Serve to protect materials from the formation and development of putrefactive bacteria and mold fungus.

As a result of clogging open pores on the treated surface, decreases

paints, glue, putty and other finishing materials, as well as the waterproofing properties of building structures.

Soil technology

The table shows how to use primer when performing internal and external finishing works. It is applied to the surface with a wide brush, a painting roller or a pneumatic pulverizer:

Illustration	Description of work
	Preparation for painting: Clean the surface from the old coating, peeling paint and shuffling plaster; Apply a layer of soil and leave to complete drying; Surface cover with starting putty; Pollute, rebound once again and apply a layer of finish putty; After sinking it, the surface is polished and apply another layer of primer; After complete drying, you can start painting. How much the type of primer is kept in time on the factory package.
	Preparation for sticking wallpaper: From the walls to remove the old wallpaper, and from the ceiling wash the chalk or lime plaster; On the surface purified from dust, apply a layer of primer and give it to dry completely; If necessary, align the walls and the ceiling with finishing putty, pollute and apply another layer of soil; After its drying, you can start shook wallpaper. When applying, the primer should not drain along the walls, and the rate of flow to 1m2 should be in the range of 100-200 ml.
	Preparation for firing with clapboard and siding: Wall cleanse from peeling solution, street dirt and dust; Apply two layers of primer with intermediate drying of each layer at least two hours; For further work, you can proceed not earlier than a day after applying the soil. When processing large areas, I advise you to use a spacker. In this case, the work will go faster, and the flow rate of 1m2 will be less than when applied with a brush.

To prepare walls under the wallpaper or painting with light paints, it is desirable to use white primer. Before taking the entire volume of the soil, you must first mix with a small portion with a dye, and then add everything else.

Varieties of primer compositions

Any domestic deep penetration soil is made in accordance with the requirements of GOST R 52020 2003 "Materials paintwork water-dispersion. General specifications. " In order not to delve into technical details, I will tell you how to choose the correctness of the primer for specific tasks.

Primer for ceilings and walls

The choice of primer composition for walls and ceilings will depend on which building materials they are made.

1. Wooden walls - Well absorb moisture, and when wetting contributes to the development of mold fungus and putrid bacteria.

• The soil for wood should block open pores, but at the same time should not prevent the free evaporation of moisture from the strata of wood;
• To protect the tree from rotting and forming mold, in the composition of the soil should be fungicidal and antiseptic additives.

1. Brick and concrete walls - Different with high density and fine-poured structure.

• For such materials, it is necessary to use liquid primer with good penetrating ability;
• If the wall outside will be sewn insulation, then the deep-rotating primer should also have antiseptic properties.

1. Concrete ceiling - In old residential premises, it is usually covered with chalk or lime whitewash.

• To prevent sprinkling overwhelming, not very liquid strengthening primer is required;
• For application it is best to use an air spray gun.

1. Watching walls - They have a loose surface with large major pores.

• To close such pores, the primer must have a sufficiently thick consistency;
• To apply a thick soil, a fur or foam painter roller is best suited.

1. Ceilings and plasterboard walls - Different with a high degree of water absorption.

• To prevent cardboard reversal, it is necessary to use quick-drying soil brands for internal works;
• It is necessary to apply it by very thin layers, allowing each layer to dry completely.

If you do not have a soil for the walls, I will tell you how to make it yourself. It is necessary to take dry wallpaper glue or construction PVA, and mix it with water in proportion 1: 4 or 1: 6 before receiving a homogeneous mass of the desired consistency.

Floor ground

Black floors in residential premises are most often wooden or concrete, respectively, the soil should also be chosen for wood or concrete. The calculation of 1m2 floor is about 150-20 ml.

In addition to the qualities described, it must comply with the following requirements:

1. Thick consistency. Black floors can strongly absorb moisture from the soil. To clog open pores, they must be abundantly soaked in thick primer;
2. High wear resistance. In the process of operation, the first floor coating has significant loads on the draft floor, so the primer layer must be resistant to abrasion and extrusion;
3. Antiseptic properties. There may accumulate moisture between the rough and fine flooring. To prevent the formation of mold and unpleasant odor indoors, an antiseptic primer of deep penetration is used.

If you do not know how and than laundering the primer from the hands and working instruments, I advise it to do it right away until it still dry, with warm water, foam sponge and household soap.

Putting for wet premises

For processing ceilings and walls in the bathroom, in the shower or in the bath requires special primer brands, for example:

1. Silicone primer - It has good waterproof properties:

• When applied, forms a solid moisture resistant film, which significantly reduces the degree of water absorption of porous materials;
• It is impossible to apply under cement plaster, because the cement stone almost does not stick to Silicon.

1. Silicate anti-grapple primer - made on the basis of liquid glass:

• Binds small particles of mineral materials and after harvesting forms a monolithic protective layer on the surface;
• Solikates of sodium included in its composition prevent the formation of mold fungus.

* Overview of the best editorial board. On the selection criteria. This material is subjective, not advertising and does not serve as a guide to purchase. Before buying, you need consultation with a specialist.

A wide scope of application is such a paint material like primer. The main task of the soil is the creation of a special layer between the base and finish. An formed substrate must have a good clutch (adhesion) with different materials. Today, in the domestic market, you can face abundance, the consumer offers expensive and cheap products, in small jars of 0.5-1.0 liters and in huge canices of 10-20 liters. In order not to make a mistake with the choice, it will be useful to get acquainted with the recommendations of experts.

1. Purpose. First of all, before buying, you need to know which surface is planned to be applied, and what type of finishes will be used in the future. This is a very important point, since different materials are distinguished by the ability to absorb. If it is important for metal products to create a good protective layer on the surface, the primer should penetrate into the tree or concrete deeply. After such an operation, paint, glue, plastering is significantly reduced. The concept of universality is not always an advantage for primer, so it is better to give preference to specialized compositions.
2. Recipe. Many different primer recipes are invented, they all have a common foundation. The active ingredient may have acrylic, alkyd, polymeric or epoxy origin. Water or organic compound is most often used as a solvent. But additives created a large number. Antiseptics prevent the appearance of mold and fungi, the administration of silicones increases the water-repellent of the soil, polymer additives increase the penetration depth.
3. The depth of penetration. One of the most important primer parameters is the degree of penetration into the base. The maximum depth of impregnation is required for porous materials. This is concrete, cement-sand plasters, wood. The depth indicator should be within 10-15 mm. But for metal parts it is more important to create an anti-corrosion layer on the surface with good adhesion. In this case, the depth of penetration may be minimal (up to 1 mm).
4. Drying time. Since the priming operation is intermediate during the repair of premises, buildings or cars, then the maximum quick drying is required. The most optimal option is 1-2 hours, this time can be used for lunch or preparation for finishing finish.
5. Cost and flow. The cost of primer in the Russian market seriously fluctuates, even on the products of one brand. The fact is that many well-known companies have created joint production in our country where paint material is produced. Not always quality is comparable to the original products, but the low cost is pleasantly surprising. In addition to the price tag, it is important to find out the consumption of primer for each type of base. Often, cheaper primers require 2-3-layer applying, which leads to increased consumption. This moment is worth considering when comparing multiple products.

We selected the 15 best primers in our review. All of them are sold in Russia. When distributing places in the ranking, the opinion of the expert community and consumer reviews were taken into account.

The use of primer mixtures when performing repair work has long become a mandatory requirement. After all, any material should be kept on the base tightly, firmly. For this purpose, the soil is used. But it is not always easy to deal with which primer for the walls is more suitable. In this article, let's talk how to choose a variant with suitable properties.

Good primer will become an indispensable material when performing any repair. Through the use of such materials, the overall quality of finishing works is improved. In addition, it is extended the life of the walls of the wallpaper, in general, any materials, with which the surface is processed.

Consider the main functions that print for walls performs:

• Protection of metal elements from corrosion appearance.
• The formation of a protective film that increases moisture resistance.
• Alignment or a significant reduction in absorbent properties. Regulation of the porosity of the main material.
• Protection against mold, fungi and bacteria. A particularly relevant property for premises, where an increased level of humidity is always preserved.
• Dusting, surface alignment of the wall.
• Raising strength, increase the durability of materials.
• Increasing the ability to adhesion, thanks to which the finish is better enclosed with the surface. The primer prolongs the life of the base.

Important selection parameters

There are not so many characteristics that can affect the adoption of a particular decision by the buyer:

• Manufacturer. It is better to give preference to companies that have already proven themselves, have a certain reputation in the market, create various primers, types of materials for processing.
• Structure. He is written on the label, as well as the designated area of \u200b\u200bapplication. Some varieties of materials may contain harmful substances. Then the manufacturer includes additional requirements. For example, when processing, it is necessary to use protective equipment or becomes necessary to ventilate the premises. Types of water based walls are becoming an excellent choice for residential premises.
• Humidity level. Antibacterial and anti-grapple processing requires special attention if this indicator retains a high level. Not every type of primer contains all the substance necessary for such treatment, including color.
• Types of finishing materials used. Well, if the basics at the finishing and the primer itself coincide with each other. Then there is an opportunity to achieve a qualitative result. Excellent solution - the purchase of products from the same manufacturer.
• What the walls themselves are made. Each of the types of materials (concrete, brick, plaster, etc.) requires compliance with special conditions during processing. This affects the composition of the primer for the walls.

Popular products

You can bring some examples with stamps of primers who are famous among buyers:

• Ceresit CT 17 is a kind of universal soil for walls.

• Job Tiefgrund. At the heart of this material - acrylic. Suitable for use in the processing of brick and concrete, drywall and plaster. The material deeply penetrates into the base, contributes to strengthening and improving adhesion. Therefore, in many situations it is recommended to choose a primer from this manufacturer.

• Tikkurila Euro Primer. Concentrate to strengthen the foundation. It takes only an hour and a half. It has antigigital, water-repellent properties. It is not only suitable for dry rooms, but also for territories with high humidity. The best primers for connecting to the paint of the same manufacturer.

• Tikkurila Luya. The composition with insulating properties, with the addition of the anti-grab component, is suitable for rooms with high levels of humidity.

• Tikkurila OTKS. Adhesion type material. Alkyid base is added to it, the composition itself almost instantly dries. Adjusts the use of tserving technology.

• Feidal TiefGrund LF. The purpose of the primer remains standard, regardless of the manufacturer.

• Bergauf Tiefgrant. A mixture of deep penetration, characterized by economy. Universal acrylic composition with water base.

• Knauf Tiefengrund. A solution that is ready for use immediately after purchase. Increases adhesion and strength, dries quickly.

Sellers and consultants of specialized stores help in the right choice of primers for walls.

Main types of material

Different types of primers perform one function or several minutes. Primers differ not only in composition, but also by the material of the base, the mechanism of impact.

On video: types of primers.

Classification depending on the mechanism of exposure

Consider in more detail how different types of primer can interact with walls:

• Deep penetrating. Used for walls that are characterized as weak or loose, porous. The compositions of this type contribute to the reduction of porosity and improve adhesion, improving the strengthening properties. Best of all combined with such types of finishes, like heavy wallpaper, spiteling and staining. When processing the walls of such a primer, the paint used hereinafter is spent in smaller quantities. But with weakly absorbent compositions, this option is not recommended. Each buyer, however, independently decides which primer to choose.

• Adhesion. Improve the adhesion of the finishing materials with the base of the walls. An excellent addition to surfaces with a large density, but weak water absorption, for example, to the cafél and glass, steel, plastic, PVC. Use such a primer for the walls will be easy.

• Mixtures of anti-grab type. They are used to prevent the development of harmful microorganisms. In the bath and kitchen, this processing will be particularly relevant. This applies to any porous and weak surfaces with a tendency to destruction. What kind of primer will suit them, we have already figured out.

• Insulating type primer. Form a vapor-permeable film on the material being processed. The basis is the most isolated from the finishing finish of any varieties. Such processing is needed, if, for example, the transition from the water-emulsion paint to the oil, or in reverse order. In addition, the insulating types of primer becomes an excellent disguise from defects on the walls: traces of markers, other finishing materials. The OGRanta makes any solutions more efficient.

• Universal group. The compositions of this type are characterized by both insulating and heat insulating characteristics. They contribute to the hardening of the main material, create a resistant film regulating adhesion together with the water permeability.

As you can see, very much varieties. What kind of primer will become the best choice? It all depends on the type of surface, the conditions of operation of the walls and the desired effect.

Classification depending on the composition

The primer may consist of natural or synthetic substances. Distinguish the following varieties of materials depending on the components inside:

• Mineral group of soils. The binding element in this case often serves cement. Sometimes it is replaced with different types of plaster, lime. Such materials are most suitable for primary processing of materials like gas-silicate, ceramzit concrete blocks, plasters, bricks, concrete, and so on. The compositions of this group fill even the smallest pores, due to which the surface being processed is maximally aligned. Such a primer is used before sticking wallpaper on the wall. A specific period of drying depends on the properties of the composition used.

• Ground solutions of an alkyd group. Phosphate or zinc chromate - materials that are most often chosen as the basis. The first option is famous for its ability to provide additional protection against corrosion. Usually it is used before applying an alkyd mixture. And the second is more versatile, it increases adhesion for any materials.

For wooden walls, the use of alkyd primer will be the ideal option. But permissible and alignment with such materials as steel, fiberglass, tile, glass. For mineral bases and drying, such formulations are not recommended.

• Acrylic wall primers. Representative of universal compositions. Can be used for walls made of any material. Only with metal is not very good, due to the likelihood of corrosion. Therefore, it is necessary to be attentive when the selection of primer is made.

• With the basis of PVA. Material with the largest amount of deficiencies. Therefore, after the selected purchases of this type, many remain unhappy.

Child selection depending on the surface

Here are also permissible several options:

• Glass and plastic. Primer, mainly decide to use to improve adhesion. Because the materials mentioned above are not capable of pulling moisture. There is always a high probability that the finish finish will last long.

• Metal. Due to pre-processing, the base will receive additional protection against corrosion. Clutch with other compositions and components is improved.

• Wood. Here the properties of primers and their functions remain the same as in the previous case.

• Mineral bases. It is better to say to the sellers in advance about, for walls from which material is bought primer. And also to tell well, in what condition is the material under the finish. In how to use the primer, it will be easy to understand.

A separate conversation deserves primer for the wall under the so-called stucco. It can be used for any materials, including foam concrete or concrete, brick. High looseness and absorption - the main characteristics for this mixture.

In this situation, the primer of deep penetration will become an excellent choice. It has antiseptic properties, will absorb extra moisture.

Before plaster, the primer composition is applied in several layers. Rollers or brushes - optimal choice as a tool. To dry out each layer leaves at least an hour. The main thing is that during this time, dust and dirt did not fall on the walls. The temperature can be kept as the same as when the use of universal primers.

Having thoughtfully finishing the walls, ceiling or floor, I want to perform work as practical as possible, even if the working surface looks old and porous. The masters are easily coping with this, as the secret of success is concentrated to use a special surface treatment. We will understand together in the appointment of acrylic primer deep penetration and technology of its application.

Features

Acrylic primer of deep penetration is a special material for surface treatment before performing finishing works, in the finished form of a consistency resembling milk.

Color can be different: more often it is transparent, sometimes white, pinkish, light gray.This primer is one of the varieties of acrylic soil. It is not a versatile means, so the purchase of material should be based strictly on the prescription.

Today, no type of finishing work is required without such soil. The material is a bit sticky, if you do not immediately wash off from the hands, it is removed with difficulty.

Sold mainly in banks and canices. The volume depends on the standards of the manufacturer. More often such compositions are released by a volume of 10 liters.

If you get into the eyes, you need to urgently rinse them with ordinary water. The skin does not eat, depending on the base, it may be eco-friendly odorless or with a small specific aroma that does not prevent the workflow.

This material is sold in the form of a dry mix and finished solution treatment. In the first case, this is a powder that needs to be breeded with water according to the instructions.

Water use cool: the operational characteristics of the construction product will suffer from hot. It is convenient, as such a material usually grabs for flooring, walls and a ceiling of a spacious room.

Remains can be stored for 12 months, tightly closing the lid and remove the raw material in a dark place. Store it in the cold is unacceptable. The shelf life of the acrylic primer of deep penetration is 2 years from the date of release. The masters are not recommended to use it after the shelf life is over.

Advantages and disadvantages

Acrylic deep penetration soil has a lot of advantages. Such a means strengthens the base, making its structure quite strong. It is possible to use this composition for outdoor and internal work. It is suitable for the most unreliable grounds that externally do not instill confidence in the success of the cladding. This primer has a high viscosity. Its convenience is water solubility.

The use of acrylic soil allows you to save on the amount of adhesive composition or paint: the treated surface no longer absorbs the liquid in the large volume, so it does not dry quickly and allows for finishing works carefully, without a rush.

After processing this primer of dark surfaces, the paint falls uniformly without non-rectified sites, strips and other defects. At the same time, the gloss of the surface is more pronounced. Regarding the remaining components of the finish, it can be noted: applying tile and wall-mounted glue after applying the soil becomes more uniform, which simplifies the finish.

Latex primer inherent vapor permeability. Despite the fact that it penetrates deep into the ground and strengthens even porous surfaces, microorganisms and mold will not appear on it. At the same time, the primer itself after applying does not slow down the facing operations: it will dry quickly even at normal room temperature. Drying time can be different, as it depends on the type of solvent used (fast, slow, classical).

A disadvantage of acrylic primer is some inconvenience of concentrate breeding, which is not like everyone. Basically, this is neglected by newcomers, which are afraid of accuracy to recreate the desired consistency, which leads to an increase in the flow of the soil.

Despite the fact that the primer can process different types of surface, not each composition is suitable for treating dark metals. Therefore, the use of this means for cladding is permissible only if the desired type of surface is in the list, it is marked on the package.

What is needed for?

Acrylic (or latex) primer is suitable for surfaces of different composition. The material is based on the attachment of the high adhesion to the treated plane followed by the applied material. It is needed so that the finish keeps on the surface as long as possible.

This primer does not just handle the top layer of the base under the finish:it penetrates a depth of 5 to 10 cm deep into the plane to which is applied.

The action is based on penetrating ability, which allows you to strengthen the walls made by the developer with a violation of technology. This is more often concrete walls or plaster, in which the sand is noticeably more than the norm. Such surfaces are tremended, which makes it difficult for the finish process and may affect the final result. The action of acrylic soil allows you to penetrate deep into cracks and problem areas of surfaces.

The material connects not only microcracks: it connects dust and causes all surface zones with a risk of poor strength to retain the facing material. It is not important at all, the wallpaper is, ceramic, ceiling tiles or bulk sex. An interesting feature is the formation on the surface in the process of frozen the rough grid, which levels the base, performing its preparation for subsequent processing.

Acrylic primer is suitable for processing cement-concrete screeds, it is possible to process wooden, plaster types of surfaces, limestone. It glues the smallest foundation particles, will help prevent the formation of blue and rotting.

Application technology

Application of soil to the surface is easier than it seems at first glance.

When working, you will need:

• foam roller;
• flat brush;
• little flat brush;
• gloves;
• flat container under the primer.

In the case of a dry concentrate to this set, it is worth adding a container to dilute material that is bred strictly in the proportions specified by the manufacturer (usually 1: 4).

The stirring is carried out until the composition does not become homogeneous. At the same time, it may be necessary to make a mask so that the dry makeup does not get into the lungs.

After the preparation of the necessary inventory and the primer itself, proceed to processing surfaces. The soil is poured into a flat container, approximately 1/3 closing the roller placed in it. It is not worth pouring more: the solution will be drained from the roller in large quantities, which is uncomfortable when processing the surfaces of walls or ceilings. The roller is convenient because with it, the time spent on the surface treatment is reduced twice.

To pour the walls is not necessary: Primer and so high penetrating ability. However, it should not be saved too: the main thing is that when rolling the surface there was no spray. Movements should not be sharp: this is especially true if the repair in the partial room is. If the soil falls, let's say on the wallpaper, they can remain stains.

The solution is gaining to the roller and rolling the surfaces to them for further lining. Since in any work can not do without treating the angles of joints and uncomfortable places, the working tool is changed to the brush of the desired size. The roller does not cope with the neat handling of the corners: usually, in this case, do not avoid flops on the walls.

The brush will avoid unnecessary consumption, make the processing more accurate.

When all the planes are processed, you need to immediately remove the remnants of the primer from the tools and the containers. If you leave it for later, the porolon and bristles brushes will become oak. After they are frozen the brush and the fur coat from the foam rubber will have to throw out. In the process of work, the material is worth pouring into the container a little by: to pour the remains back to the common canister will not work (they will be the smallest dust particles or cement screed microfragments).

Ground the surface twice. At the same time, the reuse of the soil is possible only after the first layer is dry.

What to take into account?

To carry out finishing work, it is not complicated due to the choice of incorrect primer or its incorrect application, it is worth considering several recommendations.

Having penetrating wallpapers, cracked paint or plaster, falling down tiles - all these are the problems that those who decided to save and abandon the progress of the walls may occur. The soil application procedure does not take much time and will not hit the pocket, but will allow to provide a better adhesion with the wall surface, and in some cases even save consumption of materials for the finish coating. Not so long ago, the primer mixture was prepared, spreading glue with water, but now many finished means appeared on sale, allowing you to choose the optimal composition for any type of surface, finishing material and room conditions, for example, the primer of KNAUF. We define what kind of primer to choose for walls in each case, and how not to be mistaken when buying.

№1. Why do you need a primer?

This question is asking everyone who is engaged in repairs, doubting that the soil is generally needed. So why do you need a primer and what does it consist of? The primer mixtures include film-forming polymeric materials (resins, oils, adhesives), pigments, drying accelerators and various kinds of additives to impart the necessary qualities. Primers do not have decorative properties, are used under, but if necessary, they can be cached to simplify the process of applying cladding.

Produced primer in the form of ready-to-apply compositions on the wall of compounds or powders, which you need to prepare according to the instructions. The composition may differ significantly depending on which surface is intended for the surface, and what conditions will be indoors where it is used. Regardless of the composition the primer functions remain unchanged:

Manufacturers offer today a huge variety of compounds that can confuse an unprepared person and make it from hopelessly not quite suitable material. To decide which primer is better to choose, you should clearly understand, which surface will be applied, consider room features and type of future finishing material. You can find special compositions for metal, wood, or for places with high humidity. On the manufacturer specified by the manufacturer it is worth paying attention, but it is better when you can reweper it, knowing the features of this or that composition, so it is worth studying the properties of the main types of primers before buying.

№2. Types of primer for walls in composition

Depending on the features of the composition, such main types of primer:

• acrylic primer- Most universal compositionwhich can cover wood, chipboard, brick, old and fresh. Acrylic primer can be used to treat porous bases, does not smell, quickly dries (about 5 hours), forms a "breathable" surface. The only minus is not suitable for priming metal surfaces;
• alkyd primer - Ideal for processing wooden surfaceswhich under the action of such a primer acquire a slightly strolled structure, due to which the beautiful is achieved adhesion with any finishing materials: from wallpaper and painting to cement-sand coatings. One layer of such a primer dries about 15 hours. Substances that impede the development of corrosion and the appearance of mold can be added to the composition;
• glifthalian primer - one of the few compositions that can be processed metal surfaces. It is also sometimes used to apply on. Drying the primer during the day, but has a limit - is suitable only for relatively dry rooms, since with constant exposure of high humidity loses its properties;
• perchlorvinyl primer - Universal composition, which can be treated with wood, brick, plaster and even metal. It dries quickly, and in summer at high temperatures one layer dries in 1 hour. Inside the residential premises, this primer is not used due to its toxicity, but for external work She can come up;
  
• polyvinila acetate primer consists of polyvinyl acetate dispersion and latex, can be applied on any surface and is used only as the basis under polyvinyl acetate paint. Dries quickly, up to 30 minutes;
• phenolic primer Used as the first layer when processing metal and wooden structures. It dry up to 15 hours, used to carry out only;
• polystyrene primer It can also be used for internal works, it is treated with plastered and wooden surfaces;
• aluminum plaster, as a rule, are used to process wooden surfaces and allow you to additionally protect them from the damage to the fungus;
• epoxy primers Suitable for metal and concrete. Metal they protect against corrosion, and concrete allow you to better clutch with the finish;
  
• shellak primers used to process wooden surfaces and prevent the separation of the resin;
• mineral primers Produced on the basis of plaster, lime and, are used to process the surface of concrete and brick walls. It dries such a soil from 3 to 24 hours, which depends on the thickness of the layer and the nature of the surface material.

You can also find on sale. universal primers. The very name of these compositions suggests that it is possible to use them for applying on any surface. They are used to perform small construction and repair work when the desired composition was not at hand with specific qualities, as well as sometimes for processing surfaces consisting of different materials.

Number 3. Properties and appointment of primer

Depending on which primer will be used in the premises, the compositions with specific properties can be selected for surface treatment:

• - Option for loose and not sufficiently durable surfaces. The composition is able to perfectly strengthen such a wall and significantly reduce paint consumption. Often, such compounds are used to impregnate the surface, finished by plaster, but it does not interfere with the use of primer for applying plasterboard, brick, and. If necessary reliable primer under the wallpaper, especially under their heavy species, you can safely stop your choice on similar compositions. It is not recommended to use primer deep penetration for surface treatment with a bad ability to absorb moisture;
  
• antiseptic primer for wet rooms (Bathroom and kitchen) The composition has special substances that prevent the appearance and development of fungus, has water-repellent properties and can even reduce the ability to ignite the base. Such formulations provide as high adhesion that the surface of the material and the finish are very high, and no microorganisms can be leaked to the connection. In the bathroom, it is recommended to apply primer into three layers;
• anticorrosive formulations Indispensable in the processing of metal surfaces, prevent the formation of rust, increase the service life;
• adhesive formulations and contactless primers Use when it is important to achieve a maximum clutch level with a smooth and absolutely inevitable surface (concrete, previously colored walls). Their composition includes sand or needle quartz particles, increasing adhesion. Such primers can be used to process the base before.
  

Manufacturers must indicate the packaging, for what type of surface is the primer, where it is recommended to be used, and which approximate consumption of the material will be with different types of surface. Specialists advise when choosing a primer to pay attention to the products of those producers whose finishing materials you use, - as a rule, the products of one company are perfectly combined.

№4. The best manufacturers of primers

It is unlikely that you can argue with the fact that the primer from a large eminent manufacturer has high quality. Buying the composition from a little-known company is always a risk: maybe you are lucky, and the material will correspond to expectations, and may not have the declared properties or, worse, will ruin the surface. If you do not want to risk the quality of repair, it is better in the store to immediately go to the shelves with products famous primer manufacturers:

• Ceresit. - The leader in terms of production of building mixtures, has existed more than 100 years and always bets on advanced technology, quality control and extension of the range. Due to the fact that today the company's plants are located in Russia, the cost of products managed to reduce without loss of quality. In the assortment there is a primer and primer-concentrate of deep penetration, primer for absorbent mineral bases, primer under decorative plaster and primer-contact contact for processing smooth bases;
  
• Knauf. - The German company, has existed since the 1930s, in the domestic market has been represented since 1993. Here you pay great attention to innovation, continuous improvement and implementation of comprehensive solutions for repair work.

The assortment has universal formulations, primers for highly absorbing surfaces, and primer concrete contact.
  

№5. How to apply primer?

The process of applying primer is not more difficult than. Experts recommend to handle the grinding wall not only under the finishing material, but also before it (applying plaster or). Before applying the primer under the facing layer, it is necessary to make sure that the surface is smooth, smooth and does not have noticeable defects.

To work, you will need the selected primer, bath and tools for applying: For processing hard-to-reach places. Some use a pulverizer, but its application is not always justified. The consumption of composition depends on many factors and on average is 100-200 ml per 1 m 2. The main surface is processed by roller, the corners and the most difficult places are grounded with a brush. When the first layer of the sink is embarking on the second, if it has a need (when the structure of the walls is continuing). After complete drying, the primer can be moved to finishing work.
