Today, the sphere of the finishing and construction market offers the consumer a fairly wide selection of finishing materials with a wide variety of properties. It should be noted that among the materials presented in this group, the buyer is most often interested in the primer.
What type of primer should I choose? Next, we consider the main types of this finishing material, as well as the main features of each of them.
The basis of the composition
As practice shows, the composition of all those primers that are presented on the shelves of construction stores includes for the most part the same standard components.
Universal acrylic primer without fail includes an organic or aqueous dispersion. In the composition of this material must also be present means, the effect of which is aimed at increasing the viscosity of the total mass. As such, as a rule, drying oil or resin is used. Also, on a mandatory basis, a drying accelerator is included in the composition of any type of primer.
In order to increase demand for products, different manufacturers strive to make it unique by adding special elements to the composition of the material. Among these, chalk, mica, and marble particles are often found. Higher quality of the material is achieved by adding additional components from the category of antiseptics, antifoam agents, ethylene glycol, etc. to the primer.
The composition of modern primers also includes tinted pigments.
Types of universal primers
The modern market of building materials offers a wide selection of primers for wall decoration, but they are all presented in three forms: dry, liquid and in the form of an aerosol. Consider the features of each of them.
Speaking of concentrated universal acrylic primer (dry), it should be noted that it is a concentrate, which must be diluted with water before use, exactly following the instructions on the material packaging. The main advantage of this type of composition is that when using it, you can independently control the consistency of the product. If there is no desire or need for such a procedure, you can use a solution that is sold ready-made.
Recently, the primer, presented in spray cans, has attracted special attention. The main advantage of this mixture is that it is applied very economically. However, as experts in the field of construction work, it is irrational to use soil in aerosols, since the cans in which they are offered have a small volume.
Modern primers are also divided into separate types, depending on what the principle of the effect of the material on the surface is. Let us consider each of them in more detail below.
Deep primer
It should be noted that the deep penetration universal acrylic primer is one of the most common building materials in the group under consideration. Specialists in the field of construction and repair recommend using it on planes that are characterized by friability and a poor absorption rate. Often this type of universal acrylic primer with high penetration is used during the repair of old rooms.
The ability of the material to penetrate well and quickly absorb even into the most inaccessible cracks in the wall is due to the fact that the composition of the material includes latex that can break through the thickness of the base, firmly connecting it to the product. Practice shows that due to this quality, the finish will be distinguished by durability. Also, experts note that the consumption of finishing material is significantly reduced.
Adhesive primer
The peculiarity of the composition of this material is that it contains fine and quartz fillers, due to which there is a stronger adhesion of the soil finish to the base.
Builders note that this type of soil is ideal for finishing non-absorbent surfaces, vivid examples of which are ceramics, plastic, glass, etc.
This type of concentrated universal acrylic primer with high adhesive ability is often made with a certain shade, which allows you to quickly identify those areas that have not yet been processed.
Impregnating soil
This is a universal type of primer. Its main purpose is to use it on a surface that has the ability to absorb soil unevenly. Practice shows that the material under consideration is often applied in several layers, due to which, in fact, the moisture absorption of the treated base is improved.
A significant disadvantage of this material is that its consumption can not be called economical.
Strengthening primer
This type of material is often recommended by experienced specialists in the field of construction and decoration. Its main feature is that this material is intended for bonding the smallest particles. The action of this material is similar to that of cement - when it hits the surface, it fills all available voids and even the smallest pores, but at the same time, its active components do not penetrate excessively deep into the base, simply fixing the exfoliated areas.
In practice, this type of universal acrylic primer is used to treat mineral substrates, for which a certain proportion of chalking is characteristic.
Classic
When considering options for finishing material, special attention should be paid to this type of universal soil. This material is very popular in the modern market, as it combines absolutely all the features of the above tools.
Universal acrylic primer tends to penetrate deep into the base on which it is applied. Thanks to the use of this material, the surface of the wall becomes rougher and stronger. Moreover, this substance allows you to even absorb properties over its entire area.
Most of the reviews left by builders about this material say that, despite the universality of the material, its use does not always give the result that is characteristic of the species considered separately.
Anticorrosive primer
In addition to a universal acrylic primer, a material that has an anti-corrosion property is also in great demand. Its main feature is that among the components included in the structure of the material there are substances that prevent corrosion, due to which such a primer is used to coat metal surfaces.
The main principle of its effect is to create a waterproof film on the surface, which also serves as an excellent basis for further painting of the material. Often, a layer made of anticorrosive primer is used as a finish.
Benefits of universal primer
Practice shows that at present, a universal acrylic primer with high penetration is quite widely used for treating various types of surfaces. This is due primarily to the fact that this material has a lot of advantages. Let's consider them in more detail.
First of all, it should be noted that the technical characteristics of the universal acrylic primer indicate that this material allows for proper repulsion of moisture from the wall surface, thereby significantly extending the operational life of the treated object. Due to this property, a low consumption of finishing material is ensured, which is also often used for finishing.
Thanks to the use of a universal acrylic primer, enamel gloss is significantly improved. Practice also shows that if you apply soil to a dark surface and light paint on top of it, then its shade will not be darker.
And of course, the main advantage of the considered finishing material is that with its help it is possible to give the surface more strength, even if it was originally loose and porous.
About primer consumption
Considering this issue, it should immediately be noted that the lowest consumption is characteristic of a concentrated type universal acrylic primer, since the builder has the opportunity to independently control the density of this material. In all other respects, the level of consumption of the product directly depends on what type of surface it covers. So, if we take into account the primer consumption for a rough and porous surface, then it will undoubtedly be large. As practice shows, the average in this case is about 120-160 g per 1 square. m
It is easy to guess that the consumption will be large even if the soil is applied in several layers. Practice shows that a liter of standard material is enough to cover about 10-12 m 2 of surface. If you need to calculate the exact indicator, you need to determine the exact expense of the product by one layer, and then multiply it by the number of coatings.
When determining the flow rate, the tool with which the material will be applied is of considerable importance. Modern builders strongly recommend using a spray gun, which saves both time and primer. In addition, you can use the roller and brush. As for the roller, this tool provides a large expenditure of funds, but its use saves a significant part of the time. Speaking about the brush, it is worth noting that this tool saves material, but it takes a long time to work.
Top soil producers
Currently, the building materials market offers a fairly wide selection of primers, however, as practice shows, several manufacturers offering the best material stand out among their total number:
- Ceresit;
- KNAUF;
- Tikkurila;
- Weber
- Caparol;
- "Prospectors";
- Grida
In the presented list there is also a product presented by the Russian manufacturer - the company "Prospectors". The universal acrylic primer of this company receives a lot of positive comments about the cost-effectiveness of the product, the quality of the material. Moreover, they note that innovative technology is used in its production.
The domestic manufacturer also pleases with the quality of the universal acrylic primer Grid (10 kg). The consumption of this product is relatively small - about 100-120 g per 1 square. m. Moreover, the material has antiseptic, adhesive properties, and also has a high level of resistance to moisture and is convenient to use.
Special attention of buyers is also attracted by the material from the company Ceresit (10 l). The universal acrylic primer of this company is famous for the best quality. It is a liquid concentrate that is economical and easy to use. Moreover, this material is considered indispensable for the processing of smooth surfaces and acts as an excellent basis for the further application of decorative plaster.
