13 best deep penetration primers and their characteristics

What to consider?

So that finishing work is not complicated by the choice of the wrong primer or the wrong application, it is worth considering a few recommendations.

Experts recommend paying attention to the expiration date when buying. If less than a month is left until its end, and the product can certainly remain, either they take it right next to the purchase, or choose a different brand of material

To maximize adhesion, before applying the primer itself, the surface must be free of dust, dirt and especially grease stains that impede a quality finish. Distributed by means of a roller over the surface of the facing cloth, dust, grains of sand will prevent further gluing of the wallpaper, causing small bubbles under the wallpaper.

The cladding can be made after the second layer of soil has completely dried. This is determined by the fact that when it touches the surface, it does not stick. The walls are primed before processing. If the repair is not planned for another month, there is no wash to apply the primer in advance.

The floor must not be primed if it is not prepared and there are significant cracks: this will lead to the composition leaking. He will not fix big problems, for this you need to use a cement composition.

See below for deep penetration primer application instructions.

BOLARS

BOLARS is a Russian company that has been producing building mixtures for over 15 years. Its penetrating primer is well suited for all types of concrete, brick and cement surfaces, it is also used on chipboard, fiberboard, drywall.

Specifications are as follows:

• transparent or milky color;
• dries up in 60 minutes;
• work at temperatures from 5 to 35 above zero and humidity up to 80%;
• operation is possible at -40 to +60 degrees;
• does not apply to frost-resistant;
• consumption 80 ml / m2.

Bolars

The emulsion is fire resistant, environmentally friendly and solvent free. But when working, you must use protective equipment: gloves, a respirator.

Sold in various containers from 1 to 30 kg, which should be stored out of freezing and protected from direct sunlight and moisture.

The penetrating primer strengthens loose surfaces well and increases adhesion with subsequent layers of finishing materials, while allowing the walls to "breathe". Surfaces treated with this emulsion lend themselves well to coating with various paints:

• acrylic;
• water-based;
• water-dispersive;
• acrylostyrene.

The technical characteristics of the primer of a large Samara manufacturer are as follows:

• approximate consumption of 160 ml per 1 m2;
• the thickness of the applied layer is 0.1 mm;
• drying time 60 minutes;
• application temperature from 5 to 28 degrees Celsius;
• operation of the finished coating from -40 to + 60C;
• moisture penetration during work is not allowed.

Suitable tools for work: roller, bath, brush. The primer is applied by hand only.

The emulsion prevents the destruction of the surface by biological substances, makes the base resistant to atmospheric stress, and reduces the consumption of textured coatings.

What is a deep penetration primer for and how does it work

An indicator for the use of a deep penetration primer is a dusty surface. That is, the dust cannot be removed completely. How can I check this? A surface is considered "dusty" if a trace remains on the hand after touching, even after careful and (if possible) damp cleaning. Only in this case it makes sense to use this type of primer.In other cases, it will be cheaper to use film-forming or fillers.

So what kind of surfaces is deep penetration primer used for? For chalky surfaces, gypsum plaster before painting or wallpapering. Do I need to prime the gypsum under the gypsum plaster? No, they will make good friends anyway. It will also be necessary to process all sheet materials in which gypsum serves as a binder: gypsum plasterboard, gypsum plasterboard, tongue-and-groove plates.

If the material is on a lime or gypsum binder, it is "dusty". To prevent this from happening, deep penetration primers are applied

Asbestos is also treated with a deep penetration primer, although it is not on gypsum, but 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. For 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 is more expensive). If applied 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 are very small in size. The difference can be gauged by comparing a soccer ball and a tennis ball. The difference between particles in ordinary and penetrating soils is approximately the same. It is clear that smaller particles penetrate deeper.

A deep penetration impregnation or primer works like this

Very fine polymer particles dissolve, and with the liquid they penetrate through 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 absorbency at the same time), creating additional bonds between the particles of the material. As a result, after processing, the surface stops "dusting".

What happens when processing with a conventional soil composition? Moisture is absorbed into the surface, and larger polymer particles remain on the surface, only slightly penetrating inside. After drying, the polymer is concentrated in the upper small layer. This is sufficient for conventional, non-dusting substrates. Now, hopefully, the difference between a regular primer and a deep penetrating one is clear.

Deep penetration primer: which is better

As usual, there are many different brands on the market. There are Russian and imported ones. Of the imported ones, there are often German Knauf, Polish Ceresit. 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 well the distinctive features of authentic products.

Deep penetration primer: what is needed for it seems to be clear, but you also need to choose a manufacturer

There are also Russian manufacturers who have also been on the market for a long time and who monitor quality - these are Yunis, Prospectors, Volma. Tellingly, the difference in price with the “Europeans” is quite small - no more than 10-15%. There are also cheaper brands, for which the difference is more significant - up to 30%, but the reputation is unstable. And if you look at the description, you can find the difference.

Lacre

The manufacturer Lakra Sintez produces paints, primers and other paints and varnishes under the Lakra brand. This company produces deep penetration emulsions in three versions:

• universal deep penetration primer;
• interior penetrating against mold;
• interior deep penetration against mildew.

All of them are made on the basis of water-acrylic dispersion. And they are used to strengthen the bases before further finishing.

Lacre

Has the following technical characteristics:

• work temperature not lower than 12C;
• consumption on average 75 ml / m2;
• refers to frost-resistant;
• dries up in 180 minutes;
• penetrating power 6 mm;
• freezing during storage, only five cycles.

The primer is applied on concrete, brick, plaster surfaces outside and inside the premises using a roller, brush or spray gun. Also applied to floors before applying self-leveling compounds.

The second type - a deep penetration interior primer - contains special additives that prevent the appearance of mold.

The third version of the penetrating primer is also intended for interior use and contains anti-mildew additives. Packing in 1; 3.5 and 9 kg, technical indicators will be identical to those described above. The primer reduces the consumption of subsequent paints and varnishes due to the formation of a strong and homogeneous structure on the surfaces.

Acrylic primer: technical characteristics and advantages

In order to choose the necessary soil, you need to know its properties, types, and field of application.

There are two main types:

1. Acrylic strengthening primer acting only on the treated surface;
2. Acrylic penetrating primer acts at a considerable depth (up to 10 cm). It strengthens the deeper layers.

And the general properties are almost the same:

• Good adhesion;
• Resistance to damage;
• Properties to strengthen the surface;
• Water resistance;
• Water vapor permeability;
• Further savings in finishing materials;
• Antiseptic.

It is probably worthwhile to dwell separately on the determination of the conditional viscosity of the soil, because more and more often the consumer asks such a non-idle question: - What is the conditional viscosity?

Briefly, without going into special subtleties, it is defined as follows: the VZ-246 device, called the viscometer (in Latin Viscosus - viscosity), determines the dynamic or kinematic viscosity. This is carried out at a temperature of 20 ± 0.5 ° C, when the soil flows out under its own weight, through a nozzle with a diameter of 4 mm. Time is counted. This is where the viscosity index is taken, which is indicated on the product label.

Probably, the consumer will be interested not only in the time of, say, drying of the deep penetration primer, but also in its consumption per 1m2. Of course, the approximate consumption is always on the packaging, as required by GOST, but, nevertheless, it all depends on the porosity of the base, the number of layers, and the type of work that is planned after priming: wallpapering, painting, etc.

Most popular manufacturers

A list of companies with a long-term positive reputation in the construction market, one of the types of products of which are primers, will help to determine the choice of the most suitable primer:

• Knauf. The company is considered the market leader in building mixes. Its products combine a large assortment and reasonable prices. Among the products there are those that are created to solve specific problems.
• Ceresit. It is a manufacturer of high-quality mixtures and mortars for construction. The products are manufactured not only in Germany, but this does not change their characteristics for the worse, since the company strictly monitors compliance with the proportions and manufacturing technologies of products.
• Vetonit. European manufacturer, whose factories are located not only in the EEC, but also in the CIS. In a wide range of quality products, universal mixes for floor treatment are especially in demand.
• Bierss. The company is distributed in Russia. The brand gained popularity due to the combination of acceptable quality and low price. Most often, buyers purchase a water-dispersive primer "Birss" from this manufacturer, as well as a special "Concrete-contact" for processing various concrete surfaces.
• North. Russian manufacturer applying effective innovative methods. There are many brands in its products that have specific qualities, which have no analogues in other companies.For example, the water-dispersed primer "Nortex soil antiseptic", characterized by its versatility, very low price and low consumption. In addition, a line of products for fire-retardant wood protection is popular.

How to make a primer with your own hands

Often, when wallpapering, a primer is not used at all, and if they remember about it, they do not buy it, but cook it at home, for example, from PVA glue.

Expert opinion
Sergey Shablovsky
Plasterer

I recommend that you only dilute primers yourself with professional materials such as a concentrated acrylic solution. It will be cheaper than buying a universal primer, and more reliable than the "old-fashioned" methods.

From concentrate soil

To be sure of the quality of the material used, and most importantly, in compliance with the work technology, you need to know how much polymer is contained in the primer.

Expert opinion
Sergey Shablovsky
Plasterer

As mentioned above, the dry residue of acrylic / latex in the solution should be at least 7-10% for deep processing of walls and ceilings, and 12-15% for priming the floor before pouring leveling self-leveling mixtures. But manufacturers of universal primers almost always hide this information, i.e. sell highly diluted material.

It is easy to make a deep penetration primer from the concentrated one.

The way out of this situation is simple - to prepare the soil with your own hands from the concentrate. For example, a Weber MD 16 solution has a dry residue of 50% acrylic. Diluting it with water, you can be sure of the quality of the resulting product.

Proportions 50% -concentrate - water:

• for processing the floor under the levelers - 1: 3;
• for walls and ceilings before plastering, painting, wallpapering - 1: 5.

PVA glue

Perhaps this is the most famous recipe for homemade wall primer. It is used both under wallpaper and under tiles.

Recipe:

• PVA construction glue - 1 part.
• Water - 10 parts.
• Cement - 1 part, added to the solution if there is a priming under the tiles.

All components are mixed in a bucket, applied to the wall, soaking abundantly, but leaving no smudges, otherwise a film will form.

From wallpaper glue

Before gluing the wallpaper, the walls need to be prepared, but if there is no primer, it can be replaced with wallpaper glue. Prepare a weak solution as follows.

A pack of any dry glue (250 g) is diluted in 6 liters of cold water. Stir with a mixer, leave to swell for 5 minutes.

The glue primer is applied with a fur roller or a paint brush over the entire surface of the wall. After drying (after 4 hours), you can glue the wallpaper.

Consumption is 200 g / m2.

No. 4. Top primer manufacturers

It is hardly possible to argue with the fact that the primer from a large eminent manufacturer is of high quality. Buying a composition from a little-known company is always a risk: maybe you are lucky and the material will meet expectations, or maybe it will not have the declared properties or, even worse, spoil the surface.

What types of primers are

Wall primers are specially designed for vertical surfaces, interior and exterior. They can be different in characteristics, method of application, on the basis, the level of protection against negative factors.

Acrylic

This remedy is one of the best options for home use. This is due to the fact that acrylic primers contain harmless polymers devoid of a specific odor. Additionally, you can highlight the fact that they are suitable for any type of surface and dry quickly after application.

Among the main advantages are the following:

• Hides small cracks and irregularities;
• Prolongs the life of the decorative coating;
• In case of excessive thickness, the composition is easily diluted with water;
• Allows to reduce the consumption of glue and paint.

It is noteworthy that a few hours after the application of the primer is enough to start further finishing the wall.

Deep penetration before plastering

The first class of primers is a deep penetration primer.

Visually resembles milk with a faint neutral odor. After application and drying, it leaves a resistant film on the surface, thereby strengthening and dedusting the layer.

The deep penetration primer is suitable for the treatment of loose surfaces, which helps to strengthen the wall and reduce paint consumption.

It works best for creating a reliable base for heavy types of wallpaper.

Mineral

A primer based on mineral components is used for the initial treatment of surfaces for the purpose of leveling.

The primer works on the basis of mineral components, respectively, with surfaces made of specialized mineral materials: concrete, brick, plaster, as well as gas silicate and expanded clay concrete blocks.

In such cases, cement is used as a binder.

Adhesive

Adhesive primer is a special solution, the purpose of which is to improve the adhesion of the treated surface with the finishing material. In addition to improving adhesion between materials, such a primer also performs other functions:

• protection of metal surfaces from corrosion;
• prevention of mold and mildew;
• increasing the strength of cracked or porous surfaces;
• decrease in the level of moisture absorption.

Antifungal penetrating primer

Antifungal primer is an affordable and simple solution for protecting surfaces from the harmful effects of harmful microorganisms.

Such a primer is applied at the final stage immediately before finishing.

The actual issue of the use of antifungal treatment is for external walls that are under the influence of precipitation.

Insulating for color equalization

Such a substance makes it possible to align the colors of the final paint. In addition, during operation, it will allow you to maintain the brightness and saturation of the applied color for a longer time. It is used for both internal and external surfaces exposed to painting or plastering.

Universal for plastering and painting

The universal deep penetrating primer is intended for indoor and outdoor use, as well as in places where a strong adhesion effect is expected. A universal option is used for walls before painting or plastering, as well as gluing wallpaper. Additionally, it can be used for processing facades and floors.

Deep penetration acrylic primer for interior use: a must

Many people still neglect the need for a stage, when carrying out both external and internal finishing work.

These most undesirable consequences arise due to the fact that the walls were not primed. Primers tend to create a special film on the surfaces to be treated, which not only covers the surface itself, like for strengthening primers, but also penetrates deep into the wall.

Its useful role is obvious:

1. The walls (plaster) become stronger and we have, as a result, an improved structure;
2. Adhesion is significantly improved, which will have a beneficial effect on further finishing work: plaster, putty, wallpaper);
3. Improvement of gloss after application of enamels is very significant;
4. It is possible to apply light paint on a dark base.

Primers are classified according to their composition, depending on the solvent used:

• Organic Serve for facades, are highly resistant to weathering;
• Water-based (water-dispersive). More suitable for interior work. They are more environmentally friendly and odorless.

Knowing these properties, you will always make the right choice!
