Surface preparation and work execution
Applying a primer to the prepared surface.
The base must have an acceptable load-bearing capacity, be degreased, free of loose material, dust-free
It is important to remove bituminous stains, paint stains and other contaminants that can prevent the soil from absorbing and creating a continuous layer with high adhesion. The primer is dispensed ready for use, for use it should not be diluted with water
The liquid is evenly applied to the substrate with a brush, roller or brush. Wait until the composition is absorbed, avoiding the formation of puddles. Secondary covering of the base is carried out after the primed surface has dried. Make sure of this and that the substrate is still free of dust.
For priming porous surfaces, the mixture is applied multiple times. If necessary, its concentration can be reduced by dilution with water. Finished surfaces are highly hygienic and have a long overhaul interval. On the next day after priming, facing materials can be applied to the bases using hand tools and mechanized devices.

Soil advantages
Universal primer - a composition endowed with many advantages inherent in each type of specialized primer separately.
First, it is worth noting the unique adhesive qualities of the soil due to the formation of the thinnest film, which plays the role of a kind of magnet, literally attracting the applied finishing material. This not only ensures durability, but also the attractiveness of the decorative finish.
In addition, the film formed after the polymerization of the liquid increases the moisture resistance of the base, which indicates the possibility of using the composition for the treatment of both dry and damp rooms. And good vapor permeability does not create an airtight barrier.
The composition of the universal primer is also known for its penetrating and strengthening properties. Penetrating deep into the surface, the soil sticks together all peeling and crumbling particles of the surface and makes it solid and monolithic.
In other words, the foundation becomes solid and reliable. It acquires a homogeneous, dense structure. A deep universal primer, famous for its penetrating qualities, copes with this purpose especially well.
Painting with a universal primer is a simple process that makes it easy to cope with the task with rollers and several brushes in the arsenal. And the fast polymerization of the soil speeds up the repair work in general.
This is also facilitated by the impeccable elasticity of the composition, due to which the soil perfectly covers both relatively smooth metal and concrete, and complex wood, brick or stone surfaces.
After all, it is the type of surface that determines the consumption of the universal primer. In addition, the elasticity allows the primer to be applied evenly.
Both the universal acrylic primer and the deeply penetrating one are environmentally friendly, fire-resistant and non-toxic, so their use in interior decoration is completely safe.
In addition, the universal primer, the price of which is quite acceptable, is very economically consumed, while reducing the consumption of finishing materials.
Among the shortcomings, it is worth noting only that although a universal primer is designed to solve several problems at the same time, it is still inferior in efficiency to specialized formulations developed to thoroughly solve a particular problem with a base.

Unice universal primers
They are intended to prepare, remove dust and strengthen substrates before finishing or decorative coatings are applied. If you have doubts about which product is better to choose for priming, it is better to give preference to the universal look, since it can be used for both indoor and outdoor work.
Unis universal formulations can be used, no matter what the temperature and humidity of the air. The main advantage of these mixtures is a significant increase in the strength of the finish, as well as the adhesion strength of this finish to the walls. In addition, these primers reduce the absorbency of the substrate to be treated and level it out.
Universal primers maintain the high quality of the treated areas for a long time and significantly extend the service life of both walls and finishes. The product dries quickly enough, does not have a sticky layer, and in the future it makes it possible to save on the amount of decorative or finishing materials.
Variants
Eunice is a water-based primer made of polymer dispersion and special additives, primarily antiseptic and foam-reducing. The soil that penetrates deeply is able to ensure reliable retention of the finishing material on foam concrete, iron (steel), cinder concrete and limestone. Deep penetration is said to be because the liquid penetrates 0.2-1 cm deep into the surface.
"Beton Aktiv" is a concrete base product that can be applied to stone surfaces. Drying time is exactly 2 hours. You can store the primer for six months, and you need to apply it in an amount of 300 g per 1 sq. m. After processing, even such an unstable type of coatings, such as heavy structural plaster, will stably adhere to the surface.
Features, types and characteristics
Thanks to Unis, construction work will go much faster, as these substances are designed to dry in a minimum period of time. Also, the use of this mixture helps to reduce the consumption of expensive building adhesives, paint, any plaster and various floor treatment products.Another advantage of deep penetration soils is that they are good at plugging holes and cracks in all types of surfaces.
One such bucket is enough to cover a total surface of 31 m2 in one layer. From this it follows that one square meter will need up to 0.35 liters of material, which is quite economical. The outer surface, primed in one layer, dries in about three hours at a humidity of up to 60% and a temperature of 19 degrees. It should be borne in mind that the use of mixtures on the outer walls of buildings is strictly prohibited at temperatures below +5 and above +30 degrees and air humidity over 75%. If work is carried out inside a heated room, then they can be done at any time, regardless of humidity and temperature conditions.
The company produces four types of soil mixtures, each of which is suitable for a specific type of substrate and has its own characteristics:
- soil for interior work;
- universal soil;
- deep penetration soil;
- concrete asset.
Containers of 10 liters made of durable plastic of bright yellow color can be easily seen on the shelf of any hardware store. The cost of each composition varies from 200-400 rubles, which is quite economical, especially in comparison with imported goods of a similar composition. Let's consider each of the mixtures separately and learn about the individual characteristics of each.
Interior primer
As the name implies, this mixture is intended for the treatment of the interior surfaces of the room. It perfectly evens out the area of application, removes dust and increases the adhesion between the surface and the future finish. This composition strengthens the walls and floors, and also prepares them for the next stage in the application of decorative agents and finishes, which include putty, plaster, tile adhesive and directly the tiles or wallpaper themselves.
Deep penetration soil
This type is intended for the preparation and strengthening of areas made of durable brick, concrete, gypsum, limestone, plasterboard materials and gypsum boards. The main property of this mixture is clear from the name - it penetrates deep enough into the base of the surface, perfectly sealing and strengthening old, uneven materials that absorb liquid. The primer also contributes to the uniform distribution of the absorbed liquid.
This type of soil mixture provides greater strength of the applied materials and their resistance to cracks, and, like any other, increases the adhesion strength of the agents to the treated area. The use of Unis saves the costs of subsequent repair products and guarantees the preservation of the original appearance of the base.
Universal primer
This type of primer product is intended for preparation, strengthening and dedusting of surfaces before the next stage of applying finishing mixtures and decorative coatings. If you doubt the choice of this or that tool, you can safely take this universal product, because it is applicable both for the outer part of buildings and for closed rooms, regardless of the level of moisture and temperature.
The main property of such a composition is to ensure an increase in the strength of subsequent materials, as well as the strength of adhesion between them and the wall. This variety perfectly reduces the water absorption of the treated surface and evens it out. She is responsible for maintaining the high quality of the treated area for a long time and prolongs the service of other means. Like other types of primers, this composition helps to save on the amount of future finishing or decorative materials. The product dries very quickly without leaving stickiness, which reduces the repair time.
Soil concrete asset
This type of soil mixture is designed for smoothed and poorly absorbent areas. This product is ideal for all concrete, aerated concrete and gas silicate substrates before applying plaster or tile adhesive.It can be used both for priming exterior walls and for treating interior surfaces in rooms.
How to properly prime
Before proceeding with priming, the area must be carefully prepared. The base must be dry and must have load-bearing characteristics. Before applying a layer of primer, it is necessary to remove all peeling and crumbling elements from the surface, in addition, it is necessary to remove the old coating, remove any dirt - dust, greasy stains, and others, which will reduce the adhesion of the primer product to the base.
Once the walls, floors, and ceiling have been prepared, the following tools can be used to apply the primer:
- roller;
- construction brush;
- brush or broomstick;
- spray, such as a spray gun or spray bottle.
The priming liquid is evenly applied over the entire area; drips and the appearance of puddles should not be allowed. Before covering the area with a second layer of primer or finishing materials, you must wait until the primed areas are completely dry.
Primer types and their characteristics
Unice manufactures a variety of primers that are of high quality and reliability, and they dry very quickly, which speeds up finishing work. In addition, these products significantly reduce the consumption of expensive finishing materials - plasters, paints and adhesives used to treat ceilings, floors and walls.
Types of Eunice
For the most part, Unice primer is a deep penetration mixture that reliably clogs the smallest pores, holes and cracks in all types of substrates. Eunice produces high quality products that have the necessary certificates. Yunis priming mixes are packed in 5kg and 10L buckets or cans. During transportation, containers are not deformed, their appearance remains unchanged.
One 10-liter bucket will be enough to cover a surface of 30-35 square meters in one layer. The consumption of the primer per 1m2 is 300-350 grams of liquid, this consumption is considered quite economical. After priming, the base dries for about 3 hours, provided that the air temperature is 19-20 degrees, and the humidity is 55-60 percent. The manufacturer strictly prohibits applying the primer to external surfaces if the air temperature is less than +5 degrees or more than +30 degrees, the air humidity should not exceed 75%. And if the soil is used for interior work, in a heated room, then work can be performed at any time, regardless of the temperature and humidity of the air.
Eunice produces 4 types of primers, each of which is used for application to a specific type of substrate, and also has its own technical characteristics:
- mixtures for application to internal surfaces;
- universal soils;
- deep penetration compounds;
- soil for concrete.
Packaged in containers of 5 l and 10 l, durable cans are painted bright yellow. The cost of the above primer products ranges from 200 to 400 rubles, this price is very low compared to foreign products of a similar type. Next, we will consider the individual properties of each type of mixture from Eunice.
