Unis primer: types and characteristics

A high-quality primer is a necessary thing during the repair, because it is she who is responsible for strengthening the adhesion between the wall and the finishing materials. If you do not prime the surface of the wall well, then soon plaster will fall off it, and the tiles will come off along with the glue. The Russian company Unis has long established itself as a manufacturer of high-quality dry building mixtures, as well as a variety of primers that contribute to the uniform application of finishing materials both inside and outside the premises.

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 it 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.

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, dedusting it 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.

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.

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 the grip 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.

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.

Before using Unis primers, carefully examine and prepare the application area to be treated. It must be dry and have load-bearing properties. Before direct coating, it is necessary to remove all loose parts, excess coatings, remove stains and other contaminants that may prevent strong adhesion of the soil product to the surface.

When all of the above steps are completed, you need to take any tool for painting surfaces: it can be a roller, a construction brush, or a spray gun and a brush. The mixture should be carefully and evenly applied to the surface, avoiding the formation of puddles. Wait until the treated area is completely dry before proceeding.

A large number of positive reviews from ordinary users indicate that Unis products are really very good and easy to use. Many point to the excellent composition of soil mixtures, which is similar to foreign analogues.Of course, despite the similar composition, the quality of the Unis primer is inferior to its imported rivals, but at the same time their price is quite democratic, which is also noted by the majority of users.
