Today, the sphere of the finishing and construction market offers the consumer a fairly wide selection of finishing materials with a 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? Let us further consider the main types of this finishing material, as well as the main features of each of them.
Basic composition
As practice shows, the composition of all those primers that are presented on the shelves of hardware stores includes for the most part the same standard components.
Universal acrylic primer necessarily includes an organic or aqueous dispersion. As part of thismaterial must also be present means, the impact of which is aimed at increasing the viscosity of the total mass. As such, as a rule, drying oil or resin are used. Also, on a mandatory basis, a drying accelerator is included in the composition of any type of primer.
In order to increase the demand for products, different manufacturers strive to make them unique by adding special elements to the composition of the material. Among these, chalk, mica, and also particles of marble are often found. Higher quality of the material is achieved by adding additional components from the category of antiseptics, defoamers, ethylene glycol, etc. to the primer.
Modern primers also include tint pigments.
Types of universal primers
The modern building materials market offers a large 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 packaging of the material. The main advantage of this type of composition is that when using it, you can independently adjust the consistency of the product. In the absence of the desire or need for suchprocedure, you can use a solution that is sold ready-made.
Recently, the primer presented in spray cans has begun to attract special attention. The main advantage of this mixture is that it is applied very economically. However, according to experts in the field of construction work, it is irrational to use primer 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 is the principle of the effect of the material on the surface. Let's consider each of them in more detail.
Deep primer
It should be noted that the universal deep penetration acrylic primer is one of the most common building materials in this group. Specialists in the field of construction and repair recommend using it on planes that are characterized by friability and poor absorbency. It is not uncommon to use this type of highly penetrating all-purpose acrylic primer during refurbishment of old premises.
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 in question includes latex, which can break through the thickness of the base, firmly connecting it with the product. Practice shows that due to this quality, the finish will be differentdurability. Also, experts note that the consumption of finishing material is significantly reduced.
Adhesion primer
The peculiarity of the composition of this material is that it contains fine-grained and quartz fillers, due to which there is a stronger adhesion of the ground finish to the base.
Builders note that this type of primer is ideal for finishing non-absorbent surfaces, notable examples of which are ceramics, plastic, glass, etc.
This type of concentrated, high tack all-purpose acrylic primer is often produced in a specific shade to quickly reveal areas that have not yet been treated.
Impregnating primer
This is a universal type of primer. Its main purpose is to use it on a surface that tends to absorb soil unevenly. Practice shows that the material in question is often applied in several layers, due to which, in fact, the moisture absorption of the treated base improves.
A significant disadvantage of this material is that its use cannot be called economical.
Firming primer
This type of material is often recommended by experienced professionals in the field of construction and finishing works. Its main feature is that this material is intended for gluing the smallest particles. The effect of this materialsimilar to that of cement - when it hits the surface, it fills all the 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, which are characterized by a certain amount of chalking.
Classic
When considering options for finishing material, special attention should be paid to this type of universal primer. This material is very popular in the modern market, as it combines absolutely all the features of the above funds.
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 out the absorbent properties over its entire area.
Most of the reviews left by builders about this material say that, despite the versatility of the material, its use does not always give the result that is typical for separately considered species.
Anti-corrosion primer
In addition to the universal acrylic primer, a material with an anti-corrosion property is also in great demand. Its main feature is that among the components that make up the structure of the material, there are substances that prevent corrosion, due to which such a primer is usedfor coating metal surfaces.
The main principle of its impact is to create a waterproof film on the surface, which also serves as an excellent basis for further painting the material. Often a layer made with anti-corrosion primer is used as a finish.
Benefits of universal primer
Practice shows that at present, a universal acrylic primer with high penetrating power is widely used to treat various types of surfaces. This is primarily due 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 service life of the treated object. This property ensures low consumption of finishing material, which is also often used for finishing.
Thanks to the use of a universal acrylic primer, the gloss of the enamel is significantly improved. Practice also shows that if you apply primer on 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 finishing material in question is that it can be used to give the surface greater 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 typical for a universal concentrated acrylic primer, since the builder has the ability to independently adjust 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 consumption of a primer 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 sq. 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 m2 of the surface. If you need to calculate the exact indicator, you need to determine the exact consumption of funds for 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 a roller and a brush. As for the roller, this tool provides a large consumption of funds, but its use saves a significant part of the time. Speaking of the brush, it is worth noting that this tool saves material, but it takes a long time to work with it.
Best soil producers
Currently, the building materials market offers a fairly wide selection of primers, however, as practice shows, several manufacturers stand out among their total number offering the best material:
- Ceresit;
- KNAUF;
- Tikkurila;
- Weber;
- Caparol;
- "Prospectors";
- "Grida"
The presented list also includes a product presented by a Russian manufacturer - the Starateli firm. 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 "Grida" (10 kg). The consumption of this product is relatively small - about 100-120 g per 1 sq. m. Moreover, the material has antiseptic, adhesive properties, and also has a high level of resistance to moisture and is easy to use.
Separate 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 its best quality. It is a liquid concentrate that is economical and easy to use. Moreover, thisthe material is considered indispensable when processing smooth surfaces and is an excellent basis for further application of decorative plaster.
