Which deep penetration primer is better?

Table of contents:

Deep penetration primers are used to protect concrete from moisture, to prepare it for coloring or applying wallpaper. They are presented on the market with a diverse assortment, so the choice of the manufacturer often confuses inexperienced consumers.

We have prepared a unique rating of primers, which are well-deserved respect and demand in the domestic construction market.

Scope of application

Deep penetration primers fill the porous structure of concrete, making it more resistant to external influences and increasing adhesion to finishing materials.

Concrete has a very high density, hence a very low absorbency. Therefore, plastering or staining such a surface without prior preparation will not be effective.

Such compositions will be the only right choice if heavy wallpaper is planned to be used as interior decoration - not a single glue can keep the sheets on the concrete wall.

Despite its intended purpose, primers for concrete can be used on:

Due to its properties, the compositions of this group are considered universal.

High penetrating primers are ideal for preparing substrates in rooms with a high level of humidity - in bathrooms and kitchens. Here the walls are constantly in contact with moisture, which can trigger the appearance of fungus and wall mold.

The primer, which contains antiseptic substances, is guaranteed to prevent the development of pathogenic microflora.

Which primer is better or TOP-11 manufacturers

For this market segment, the fame of the manufacturer is a kind of guarantee of product quality. When choosing a primer of an unknown manufacturer, there is always a risk of running into a product made in violation of technological standards.

Such compositions not only do not cope with their functions, but also contribute to the destruction of the base, even if we are talking about durable concrete. “Famous” manufacturers always carefully monitor the quality of their products - this is the key to marketability.

However, even well-known companies are too much in the assortment of the store, which makes it difficult to choose. Here is a list of brands that you should pay attention to first.

"Prospectors"

The composition has the ability to fill all microcracks and pores. The addition of quartz sand significantly increases the adhesion properties of the base with the finishing material. The primer is designed for outdoor and indoor use - in rooms with high and normal humidity.

Permissible subsequent finishing:

plastering and puttying,

laying flooring.

The solution will not work on surfaces with low absorbency. In addition, it is forbidden to use on surfaces that have direct contact with food and water.

The primer can be used in all types of buildings. The data in the table may vary, depending on the type of material.

Ceresite

Company known about 100 years and over the centuries of history, has accumulated considerable experience in the manufacture of various building mixtures. Primers are available on a water-dispersion basis, synthetic resins are used as the main component.

Thanks to this combination, the primer is perfectly absorbed, while being protected from premature drying.

"Optimist"

The products of this manufacturer are suitable for indoor and outdoor use. This is a solution of fine latex with the addition of modifying additives, quartz sand and antiseptics. The composition is suitable for treating substrates that are exposed to a humid environment, helps to level the surface and increase adhesion.

General information

Primer compositions perform the following functions:

  1. Reduce the absorption of finishing materials, as they fill the pores of the surface. As a result, paint, varnish or glue are not wasted, but remain on the surface of the material.
  2. Increase adhesion (ability of materials to adhere). Although it is worth making a reservation here: if we are talking about cement plaster, then the adhesive properties will become worse, since the cement milk does not absorb into the pores - because they will already be filled with a primer.
  3. Strengthen the base, penetrating deep into the structure of loose and porous surfaces. The soil, as it were, binds together the disparate elements of the base. Reduces the likelihood of shedding of plastered surfaces, peeling whitewash, chipping mortar at the seams, etc.

Operating principle

The above properties of soils are explained by their chemical composition. Acrylic based aqueous dispersion penetrates deep into the pores of the material. Another component of the mixtures - polymers - contributes to an increase in the so-called capillary effect, which affects the penetration depth. When the moisture evaporates, small particles of resin stick together, resulting in long threads that serve as a kind of frame that holds the material together.

The principle of penetrating waterproofing to the content ↑

Composition

The composition of deeply penetrating primers includes the following components:

  1. Water. Only water-based primers are available on the Russian market.
  2. Acrylic resins. They act as a bonding element.
  3. Polymers They provide good wetting of the treated coating and allow the soil to penetrate to maximum depth.

As an option, the following components can be added to the ground:

  1. Fungicides that act as antiseptics. The antiseptic properties of the soil help prevent mold and mildew. Such mixtures are especially useful if the surface will be operated in conditions of high humidity.
  2. Latex, which increases the adhesion of small-sized surfaces. Latex also improves adhesion of low-porous materials.
  3. Silicone gives the base water resistance.

Specifications

The properties of deep penetration primers vary depending on the specific composition. However, some technical properties are similar for all soils.

Note! Some manufacturing companies offer the market concentrated anhydrous mixtures. Such compositions are diluted with water immediately before use in proportions from 1 to 1 to 1 to 5.

The primer density indicator is equal to the density of water (kilogram per cubic decimeter). In some cases, the density of the mixtures may slightly exceed the density of water.

The approximate consumption of a deep penetration primer can range between 100 and 200 grams per square meter. Moreover, the same soil can be consumed in different quantities, depending on the absorbing capabilities of the substrate.

The drying time of the primer depends on its composition, namely, on the percentage of the water base. Well-soaked materials dry for 1 to 3 hours. Optimum indicators for quick drying of the surface: air temperature - about 20 degrees above zero, atmospheric humidity - 70%.

Fields of application

As indicated above, deep-penetrating soils are primarily used to strengthen loose and porous substrates. These materials include the following materials:

  1. Cement plaster before painting. Priming helps to avoid surface shedding and also reduces the absorbency of the material.
  2. Brick for painting. Soil protects seams from spalling.
  3. Wallpaper sticker on lime whitewash. Due to the interaction with acrylic resins, whitewashing will not peel off due to changes in humidity and mechanical loads.

In some cases, the use of deep-penetrating primers is at the discretion of the master:

  1. If the plaster is applied to the shell material, the spray (the rough layer of the plaster) will hold well on the surface, despite its high porosity.
  2. Monolithic concrete, concrete screeds, aerated concrete, oriented particle boards and particle boards can be treated with quartz sand primers. Although such compositions do not penetrate too deeply, in spite of this, the surface acquires a pronounced roughness, which ensures excellent adhesion.

Primer instructions

The following is a sequence of steps for applying a primer:

  1. We clean the surface from pieces of peeling paint or plaster. We use a hard spatula. If we are talking about plaster, we tap it with a small hammer or pickax to find voids.
  2. We clean the base from dust and dirt with a brush or vacuum cleaner.
  3. Apply the primer using a brush or spray can. If the floor or walls are very smooth, it is preferable to use a roller with a long pile. Surface treatment is carried out exclusively at positive air temperature (at least 10-15 degrees above zero).

Useful advice! If there is no factory-made sprayer, the device can be borrowed from a bottle with a wiper.

Further actions depend on the goals and type of surface:

  • in the case of plaster we put beacons,
  • before applying the putty, remove the protrusions from the surface and level the pits,
  • if you have to paint, putty small defects, etc.

Separately, it is worth mentioning the use of deep-penetrating primers with gypsum putty.

Typically, such compositions are applied 2 times:

  1. First, they process the surface before puttying.
  2. The second time the primer is applied after grinding, just before painting.

If a deep-penetrating composition accidentally lands on a surface not intended for priming, you can remove it using such means:

  • soda diluted in a large amount of water,
  • acidic means of household chemicals "Cillit",
  • detergent "Mr. Muscle",
  • Acetic essence concentrate.

"Mixonit GR 43"

The primer is excellent for preparing the foundation before laying tile or facing stone.

Technical characteristics of the composition:

  • absorption depth up to 10 centimeters,
  • the absence of any odors
  • vapor permeability
  • the presence of antiseptic and flame retardant properties.

"Pro-acryl-primer"

Latex and acrylates are used as bonding agents in the primer. Also in the ground there is an antiseptic substance and a foam quencher. Thanks to antifoam, the substance does not foam when stirred.

The primer is applicable not only to mineral bases, but also to wood. "Pro-acryl-primer" can be used both for internal work and for strengthening the facade, since latex is included in the composition, which increases the material's resistance to moisture.

"Ceresit"

This brand can be called the most common choice among masters. Products are of high quality and complex, but effective composition.

"Ceresit" is used to treat any surface with an absorbent base. The composition improves the adhesive quality of materials, binds dust deposits, strengthens the base. Also, “Ceresit” does not allow to dry thin leveling solutions, improves the spreading of floor paints and materials and prevents their bubbling.

To work with highly porous substrates, the emulsion is diluted with water in a ratio of 1 to 1. Ceresit is applied in several layers.

The answer to the question of how much this composition dries is ambiguous. Due to the saturation of the composition, this primer dries for a rather long time - from 4 to 7 hours. If we are talking about gypsum and wood surfaces, the drying time of each layer can reach up to a day.

  • soil base - acrylic copolymers,
  • the color of the composition is light yellow,
  • the consumption rate of the material depending on the type of coating is from 100 to 200 milliliters per square meter,
  • the optimum temperature when applying the composition is from 5 to 35 degrees above zero,
  • soil must be stored in unopened packaging for 1 year.

To prevent fungus and mold, the Ceresit CT 99 deep penetration antifungal primer is available. The product produces in a package of 1 liter. Primer is used as a separate layer together with a deep penetration primer.

It should be remembered that deep-penetrating soil is not omnipotent: it can strengthen the loose base, but it will not fix a clearly peeling area. When purchasing a primer, it is recommended to pay attention to its compatibility with one or another base.

Bolars

This is a transparent or dull-white composition designed to strengthen cellular concrete, gypsum plasters, cement-sand and cement-lime screeds. If the surface is intended for painting, it helps to reduce the solution. LMB.

This is a universal composition penetrating porous surfaces to a depth of 6 mm. Due to its absorbency, the primer is used to prepare the facades and interior walls of the room. Suitable for rooms with a high level of humidity, can be used before wallpapering or tiling with ceramic tiles.

Knauf

One of the leading European manufacturers supplying products to the Russian market since 1993. Of the primers of deep penetration in the assortment of the company, one can distinguish "Concrete Contact" - a polymer composition with the addition of quartz sand.

Also has good reviews TIEFENGROUND - quick-drying primer used before puttying, tiling and painting.

Lacra

Composition on a polyurethane basis with the addition of antiseptics.

Fills micropores and cracks

The compounds also protect the surface from the appearance of pathogenic bacteria, fungal spores and mold. Due to these properties, the primer is ideal for bathrooms and bathrooms.

The composition creates a monophonic protective coating, suitable for preparing walls before painting with water-based emulsion and acrylic paints. It is used for concrete, brick and plastered walls, as well as for the processing of drywall, Fiberboard and asbestos-cement panels.

Application Rules

It is not difficult to work with primers, anyone can cope with the application, if he follows elementary rules.

Before priming, the base must be cleaned of dust, construction debris and oil stains.

If metal elements are present on the surface, they must be cleaned of rust.

Apply the primer with a roller or a wide paint brush, observing the uniformity of the layer.

For large rooms it makes sense to use a spray gun, which will help significantly reduce the workflow.

Primers are sensitive to cold, therefore the preparation of the base is carried out only at a temperature 5 ... 30 0 C.

Strongly porous base, as well as large cracks and cracks, are sealed and primed in 2-3 layers.

Each subsequent layer is applied after the previous one has completely dried.

Some primers require preliminary preparation, therefore they are diluted with water or solvent to obtain the optimal consistency. Commonly used for this 1: 1 ratio unless otherwise specified by the manufacturer.

Types of primers and their purpose

In the description of many types of work it is written: a primer is required for the base. For this stage, special formulations are used, which are called a primer or primer.

Application of soil - one of the stages of finishing work

What is a primer (primer) or primer? This is a liquid mortar, which prepares the surface for the application of the next layer of finish. Moreover, the “next” can be any, both intermediate and final. Take wall decoration, for example, from bare masonry to painting or wallpaper. First, the wall itself is made of building material. After the soil has dried, plaster is applied. When the plaster has dried sufficiently, apply soil to it, then putty. The puttered surface is also primed, and then after the primer layer dries, the wallpaper is painted or glued. Such a number of primer layers is not necessary, but an option is possible.

Primer is a liquid composition that provides good adhesion of the layers of the finish to each other

The primer is used when decorating walls, floors, ceilings, and facades. In general, everywhere. There are subspecies for external and internal works, there are which are used both there and there.

The tasks that primers solve

Primers should ensure good adhesion of two layers. This is their main purpose. Most often, this requires adjusting the absorbency of the substrate. The fact is that all finishing materials - plasters, putties, paints, adhesives - are developed for medium absorbing substrates. And there are not many of them. More often an absorbent ability to regulate. Sometimes it is necessary to reduce the absorbency, sometimes - to create a sticky film on a too smooth and / or poorly absorbent surface. Here primers and solve this problem.

And also compositions that lower absorbency, at the same time improve waterproofing and fight against high humidity. So this is also part of their tasks. And for this they are also used.

Primer is needed to improve adhesion.

Deep penetration primers bind particles on the surface. The compositions penetrate deep into the loose materials to a sufficient depth of 5-7 mm and bind the particles together. Often the “side” effect is a decrease in hygroscopicity and absorbency. Often - this does not always mean, so see the properties in the description of each composition.

Even on the surface after the primer dries, an adhesive film may form, since the non-absorbed composition having dried out leaves a sticky residue. This improves the conditions for applying the following material. That is, some types of primers increase surface strength and adhesion. Some of the compounds have antibacterial properties, others simply introduce special anti-mold or antifungal additives.

Sometimes a primer is used to make friends cement and gypsum-based materials. Without this, there will be no normal adhesion. For example, when a concrete wall or a wall of cement-based blocks is going to be covered with gypsum plaster, the classic and proven solution is Concrete Contact from Knauf. It is applied to almost any mineral base under gypsum materials and ensures their high-quality bond.

Types of primer substrates

So, we came to the conclusion that when choosing a primer it is necessary to focus on the properties of the base. By absorbency, they are divided into three groups:

  • With low absorbency and non-absorbent. This group includes concrete surfaces, cement plasters, refractory bricks, sand concrete, polystyrene foam, gypsum tongue-and-groove plates.
  • With medium absorbency. Ordinary brick. An ideal base that does not need to be applied. But only if the brick has not yet begun to crumble.

Wood is a complex foundation that requires application of soil

How to determine the absorbency of a surface? Apply drops of water to the surface and track the time it takes for them to soak. If it took more than 20 minutes, the surface is non-absorbent, if less than 3 minutes have passed, it is highly absorbent. Everything in between is medium absorbing. In this case, you are lucky and you can do without formulations that regulate water absorption.

Now it’s clear how to choose a primer. Film-forming are suitable for surfaces with low absorbency, and for those that use high penetration primers or fill ones. Deep penetration is only needed if the surface is dusty, but not loose and does not crumble.

Why is a deep penetration primer needed and how does it work

An indicator for applying a deep penetration primer is a dusty surface. That is, the dust cannot be completely removed. How to check it? A surface is considered “dusty” if a trace remains on the hand after touching it, even after thorough and (if possible) wet cleaning. But only in this case it makes sense to apply this type of primer. In other cases, it will be cheaper to use film-forming or filling.

So for which surfaces is a deep penetration primer used? For chalk surfaces, gypsum plaster before applying paint or wallpapering. Do I need to prime gypsum for gypsum putty? No, they are so good friends. It will be necessary to process all sheet materials, in which gypsum acts as a binder: GVL, GKL, tongue-and-groove plates.

If the material is on a calcareous or gypsum binder, it “dusts”. To prevent this from happening, and apply deep penetration primers

Asbestos is also treated with a deep penetration primer, although it is not on gypsum, it is dusty. And also silicate blocks before applying a layer of plaster. They also leave a layer on the hand. In general, it seems clear.

Note! The surface to be treated must not be loose. To do this, there is a special primer, which is called strengthening. It also refers to deep penetration soils, but contains a greater amount of adhesives (and costs more). If used unnecessarily, the absorbency may be too low, leading to problems.

How deep penetrating soil works

How do deep penetration primers work? They are made on the basis of the same polymers, only modified in such a way that the particles have very small sizes. The difference can be estimated by comparing a soccer ball and a tennis ball. The particles in ordinary and penetrating soils differ about the same amount of times. It is understood that smaller particles penetrate deeper.

Deep penetration impregnation or primer works something like this

Very small particles of the polymer dissolve, and with the liquid penetrate through the capillaries deep into the primed surface. After drying, the polymer particles remain in the capillaries, creating an additional crystal lattice there and reducing the porosity of the material (and its absorption capacity at the same time), creating additional bonds between the particles of the material. As a result, after processing the surface ceases to “dust”.

What happens when treating with a conventional primer? Moisture is absorbed into the surface, and larger particles of polymers remain on the surface, only penetrating slightly. After drying, the polymer is concentrated in the upper small layer. This is sufficient for ordinary non-dusting substrates. Now, we hope, the difference between a conventional primer and a deeply penetrating one is clear.

Primer deep penetration: which is better

On the market, as usual, there are many different brands. There are Russian and imported. Of the imported ones, German Knauf and Polish Ceresit are often found. These are companies that have been on the market for many years. There are very few complaints about the quality of their products. Here are just a lot of fakes and you need to know the distinguishing features of authentic products.

Primer of deep penetration: what is needed for what seems to be understandable, but it is also necessary to choose a manufacturer

There are Russian manufacturers who are also on the market for a long time and who monitor quality - these are Eunice, Prospectors, Volma. What is characteristic, the price difference with the "Europeans" is very small - no more than 10-15%. There are cheaper brands, in which the difference is more significant - up to 30%, but the reputation is unstable. Yes, and if you look at the description, the difference can be found.

As you can see from the table, to say that there is no difference between the more expensive and cheaper brands, it will not work. Even according to the description of the surfaces on which the composition is applied. Surfaces are significantly larger in more expensive compounds. Well, you have to look at the quality. But usually cheaper ones are used for applying paint (if it is not expensive), for wallpapering, etc. For more critical areas - such as plaster, putty, on complex substrates - they prefer not to take risks and take products from trusted companies. Quite a reasonable approach.

What is a deep penetration primer

The basis of repaired surfaces can be different materials - wood, concrete, cement-sand or gypsum plaster. Their properties have differences, so they will have different adhesion to the finish. To make it as durable as possible, use a primer. This is the impregnation for walls, which can penetrate to a depth of 5-10 mm. In the building materials market, it is represented by a wide range. Separately, it is worth noting the universal - it is suitable for almost any surface.

Universal primer

Before you buy a deep penetration primer, you should understand its types, examine products with good reviews and characteristics. So you can choose the most suitable impregnation for you. The first in the ranking is a universal primer. It is suitable for most interior work on vertical and horizontal surfaces, as well as for exterior cladding.

Deep penetration primers for concrete

Conventional adhesive impregnation is also called Concrete Contact. They are intended only to increase the adhesion of the working surface, making it rough. For coatings that need to be strengthened, such an impregnation will not work. For this reason, it is used on concrete substrates that do not absorb moisture. Deep penetration primers for concrete are presented by not less wide assortment.

How to choose a deep penetration primer

According to experts in the field of construction, the best primer is the one that meets most of your requirements. When choosing an impregnation, several factors should be considered at once. The main ones are as follows:

  1. Indoor or outdoor work. In the first case, frost-resistant compounds are required - acrylic, silicate. To work inside, the impregnation must be odorless - latex or also acrylic. For wet rooms choose antiseptic soil.
  2. Surface material. Concrete requires soil designed for absorbent substrates - acrylic, alkyd. The best option in this case is Concrete Contact - a colored pinkish liquid. Oil antiseptic impregnations are more suitable for wood, anti-alkaline for brick, and antifungal for tile.
  3. Drying time. For internal work it is important that the impregnation dries faster, because it has to be applied in several layers. Due to prolonged drying, repairs may be delayed.
  4. Finish. For wallpaper, putty, plaster and paint, you need to use different impregnations. This is indicated on the product label. For all finishes, universal primer is suitable.
  5. The manufacturer, reviews and the cost of a deep penetration primer for walls. No less important factors. Pay attention to well-known manufacturers who have proven themselves well. As for the price, then choose an affordable impregnation for the purchase. Keep track of sales and discounts.
  6. Volume. Knowing the consumption of soil and the area of ​​the surface to be treated, it is possible to calculate the required amount of impregnation.

Reviews

Aleksey, 46 years old. One of the repairs made without preliminary impregnation turned out to be that after 4 years I removed the old wallpaper with putty. I had to restore the walls before finishing. This time already previously applied soil. I ordered an antiseptic in the online store with delivery by mail. It is especially good for heavy non-woven wallpaper.

Sergey, 27 years. When choosing the soil, they were more oriented to the manufacturer and so that it was not so expensive. The optimal in this regard was the impregnation of Ceresite. We could not decide which primer to choose for the walls - antiseptic or antifungal. We do not have mold, so we took the first option. For two years now, no defects have appeared on the walls.

Marina, 34 years old. In the new apartment, the ceiling was unfinished. There was a choice between concrete contact and deep penetrating soil. The store explained to us that any option would do. We stopped at a cheaper one, there was just a stock, and took concrete contact. It really makes the surface rougher. Putty lay very well, never fell off.

Alkyd

Such a primer mixture can process wood and metal surfaces. It is better to use alkyd for processing wood indoors. There are especially durable types of alkyd primers that can be used for glass or tile. For plaster or drywall, this material is not suitable, since after applying the composition, the surface turns out to be uneven.

Shellac

Typically, this type is used for processing wood, and in raw form. It is not very popular among builders because it is a relatively new type of finishing material. This primer mix is ​​more suitable for application on a wooden surface made of coniferous species. It neutralizes the effects of resin, which is present in the composition of the tree and prevents its discoloration.

Epoxy

Known as a coating material for application to metal surfaces to prevent corrosion. It is steady against mechanical and temperature influences. In addition, it protects the metal from exposure to the sun and moisture, and prevents peeling of paint from the metal. After drying, it creates a flat surface, helping the further coating to lie perfectly. However, this species requires a sufficiently long time for drying.

Phosphate

Also called phosphating. It is similar to the previous one and is intended for metal processing, protects it from further corrosion and rust. It is based on organic solvents of synthetic resins and resistant pigments that prevent corrosion.

A feature of phosphate primers is that it must be applied in 2-3 layers to create a smooth surface.

Quartz

It is not smooth because based on quartz sand, contributing to a good adhesion of surfaces to each other. The quartz primer is distinguished by the absence of toxic substances in the composition, therefore, it is not necessary to ventilate the treated room after the work. High viscosity and the absence of volatile components allows you to apply this material in just one layer.

Conclusion

A primer is a liquid mixture that can be applied to further improve adhesion to finishing materials. It is designed to increase the service life of the repaired premises. Currently, many paints used in repairs do not lie on a surface that has not been primed. Therefore, it is a necessary element in the decoration.

Primer purpose

  • A primer is needed to strengthen the base. It penetrates into the deep-lying layers of a loose, porous plane, linking its disparate components. Priming works prevent plaster shedding, whitewashing and coloring of the mortar in the area of ​​the joints.
  • The use of soil reduces the absorption capacity of the surface, which significantly reduces the consumption of finishing materials. The effect is achieved by filling the pores of the treated surface with a primer.
  • Primer mixes increase the adhesion of almost all finishing materials, with the exception of cement plaster. Due to priming, its adhesion characteristics only drop, since the cement milk does not absorb into the pores of the facade or other surface that will already be filled with soil.
  • Some types of soil have disinfecting characteristics. They are applied to the walls to prevent the development of fungus, mold, moss, and other microorganisms.

The most popular product is a deep penetrating universal primer. It strengthens the material, disinfects and enhances penetration at the same time.

Areas of use

A deeply penetrating primer penetrates the pores of concrete, making its texture more dense and durable. Preliminary processing by soil does a surface steady against external aggression, raises its adhesive properties.

Since the absorbent capacity of concrete is too small, without a preliminary primer of the walls, no paste will hold heavy wallpaper or other finishes on them.

The primer is used for walls made of concrete, drywall, brick, gas, foam block, for processing plastered walls. Due to the variety of applications, the soil is deservedly called universal.

Highly permeable mixtures effectively prepare the base for finishing in rooms with high humidity - in bathtubs, kitchens, bathrooms. These are rooms where there is an increased risk of rotting and mold. A universal primer with an antiseptic effect helps prevent such phenomena.

Classification

Depending on the place in which the soil will be applied, it can be for indoor and outdoor use. There is another classification that takes into account the technical characteristics of primers.

There are such types of primers.

  • Acrylic It can handle concrete, wood, drywall, and other surfaces. This primer is universal. It penetrates well into the deeper layers of the base, at least 1-1.5 cm. Suitable for priming walls for gluing heavy non-woven or vinyl wallpapers.
  • Alkyd. The best option for priming for metal and wood.
  • Silicate. It is treated with silicate bricks, aerated concrete, gas silicate, concrete foundations of facades before applying plaster, including decorative.
  • Epoxy.It can be used to protect metal from rust and to increase the adhesive characteristics of a concrete base before laying bulk floors.
  • Shellac. Soil protects the wooden base from the emitted resins.
  • Polystyrene. Facade primer for external use. Toxic Primers concrete and plastered surfaces.
  • Polyvinyl Acetate. It dries quickly. It can be used indoors for the preparation of wooden, metal and plastered substrates.
  • Aluminum Protects the wooden base from moisture, mold and rot.

Knauf

Knauf is one of the leading manufacturers of building compounds. It has been implemented since the beginning of the 90s.

  • “Betocontact” from Knauf is a deep-penetrating polymer-based soil with an admixture of mineral sand.

  • Tiefengrund Knauf is a quick-drying primer that can be used before puttying, before painting and tile laying.

The primer consumption rate is from 0.08 to 0.25 l / m2. The penetration depth into the processed material is 5-6 cm. The drying time of the composition is 2-3 hours.

The composition forms a protective crust of one tone. It can be used as a primer for surface preparation before painting with acrylic and water-based dyes. The soil can be treated with concrete, brick and plastered walls, drywall, fiberboard and asbestos cement.

Priming process

Instructions for use of the primer are placed on the packaging of the mixture. It is necessary to carefully read the rules for its dilution, application and operation.

Any surface must be primed in compliance with safety precautions. It is necessary to work with gloves and a protective mask.

Using a primer takes place in several stages.

  1. Preliminary preparation of the base. It must be cleaned of dust, dirt, debris and grease stains. The surface must be checked for peeling paint or plaster. They must be removed with a trowel. Plaster should be tapped with a small hammer or pickaxe to open and clean possible voids. If painting is to be done, minor defects must be putty before priming.
  2. If it is necessary to treat the metal base with soil, it must be cleaned of rusty areas.
  3. If necessary, the mixture is diluted with water or solvent, in the ratio written in the instructions. The solvent and concentrate are taken in equal proportions, but there may be other recommendations on the packaging.
  4. Apply to the prepared surface with a brush or roller in an even layer. Smooth surfaces can be primed with a long pile roller.
  5. Large areas are primed with a spray gun.
  6. Since primers are susceptible to cold, all work is necessary at an air temperature of 5 to 30 ° C.
  7. If the base is too porous or has many defects (cracks, crevices), it must be primed in several layers.
  8. Each new layer should be applied only after the previous one has completely dried.

How to wash from different surfaces

Before priming, planes not subject to application of the composition must be protected with tape and tape. If the primer is in such places, the principle of its removal will depend on the material of the surfaces. If the mixture just got on glass, tile or tile, immediately wash the primer with a rag or sponge dipped in water.

If the primer is slightly dried, a wet rag needs to be applied temporarily to the stain so that it swells. After a few minutes, the residue from the primer can be washed off with water. A heavily soiled glass surface will need to be cleaned with a blade.

You can use special wipers Dopomat, Hodrupa or "Mr. muscle."

Before proceeding with the removal of soil stains from the tiles, the detergent must be tested on its residues. This precaution is necessary so that the aggressive components of the detergent do not damage the surface or color of the tile. You can wipe the tile with cleaning compounds, soda solution, vinegar essence, and in more severe cases a scraper. Using these products, linoleum and plastic products, including windows and doors, can be cleaned of soil.
