Best primer for floors: overview, features, manufacturers and reviews

To date, there is a huge amount of various materials for the arrangement of premises. Primer is a special building material that is designed for primary treatment of various surfaces before performing basic work. It improves the performance characteristics of other materials, increasing their resistance to negative environmental factors, and prolongs the life of building materials. You can buy it in specialized stores at an affordable price and from well-known manufacturers.

When pouring floors it is very important to perform their priming, so that they are warmer, and the flooring has lasted much longer. Therefore, many people are interested in the question of which primer of the bulk floor is better. From this article you will learn about the main varieties of this building mix and their differences.

Why is it necessary to primer the floor?

The quality and durability of the floor does not depend on the cost of the floor covering, but on how tightly they fit into the subsequent layers. With poor adhesion to subsequent layers, the flooring will overlap from the previous layers, as a result of which it will deform.

It is not recommended to lay the floor covering directly on the concrete screed, since it practically does not interact with other materials at all and does not adhere well to them. In addition, in the concrete after hardening there are voids, which significantly reduce the strength of concrete. The only solution to all problems is priming. However, to achieve the desired result, it is very important that the primer for the floor is of high quality.

What gives the priming of the floor?

Priming the floor allows you to get the following result:

• The quality of adhesion of concrete with other materials increases;
• Increase the performance of the screed;
• Concrete becomes more resistant to negative environmental factors;
• Various defects that have occurred during the filling of the screed disappear.

If your house has wooden floors, then a primer for the floor, the price for which varies from 480 rubles. Up to 3500 rubles. For 10 liters, allows:

• Significantly save on paintwork materials;
• Hide various wood defects;
• Prevent the formation of mold and fungus;
• Improve the quality of the clutch of wood with other materials;
• Prolong the life of the floor;
• Prevent resin from being separated by wood;
• Create an excellent waterproofing floor;
• Protect the tree from harmful insects.

Thus, the priming of the floor, regardless of the flooring used, is mandatory if you want to obtain a quality floor.

Its price perfectly matches the quality.

Alkyd primer

This type of primer is used exclusively for impregnating wooden floors before painting. This mixture significantly improves the adhesion of wood to other materials. It should be noted that primed wooden floors should be at an ambient air temperature of at least 15 degrees. It takes 15 hours to completely dry.

Acrylic primer

Primer for this type of floor, as you might guess from the name, is made on the basis of acrylic, so it is one of the most versatile and can be used for both wooden and concrete floors. The mixture perfectly eliminates any defects and significantly increases the strength and durability of the screed. In addition, acrylic does not emit any toxic fumes and unpleasant odors, and completely dries up in just 3 hours.

Shellac primer

It is made from insect cell juice and is designed for impregnating floors made from coniferous tree species. Drying time is 24 hours.

Glyftal Primer

Another type of construction mixture intended for priming wooden floors. It is intended for preparation of wood for impregnation with epoxy resin. Before buying this primer, you should consider the fact that it can be used only in dry conditions. After impregnation of wood, the floor is left for a day for complete drying.

Perchlorovinyl Primer

This floor primer, whose consumption is very economical, is almost a complete analog of acrylic mixtures intended for use in industrial facilities. Use it in living quarters is strictly forbidden, because the substances that make up the primer are dangerous to human health.

Polyvinyl acetate primer

Universal building compound, which is used for priming various types of surfaces before painting with emulsion paints. The mixture consists of synthetic substances, due to which it completely dries up in just 30 minutes.

Phenolic primer

Starting mixture, which has a very sharp and unpleasant smell, which is applied to any type of surface before laying wooden floors. It takes about 12 hours to completely dry.

Polystyrene Primer

Universal primer of industrial type. Because of the toxic fumes released during the drying process, it is not used in premises intended for human habitation. Used for starting work in the preparation of wood and cement bases.

Polyurethane and epoxy mixtures

This primer of polyurethane floors is designed for application to concrete substrates. It is made by adding solvents to various colorants.

General recommendations for the choice of primer

When choosing a primer, the composition of the screed should be considered. The thing is that a certain type of mixture is designed to be applied to a certain type of surface.

The primer in front of the filling floor must be carried out with starting mixtures that have a high penetrating power, in which the adhesive is present. It helps to increase the operational characteristics of concrete and cement, and also extends their service life. If there are fireproof additives or alkali in the cement screed, the primer should be anti-alkaline.

If you are already in the final stage of pouring the floor and are going to start laying the floor covering, then in this case it is worth using the finish primers. It should be taken into account the compatibility of the mixture with the type of your screed.

If you need to prepare a surface for bonding to other materials that were previously painted, then the universal mixture will not work, and the only solution will be a primer of deep penetration for the floor. When choosing a particular mixture, you should consider its compatibility with the composition of the screed.

When performing repair work to strengthen the old screed, it is also recommended to use primers with a deep penetrating power, which have a strengthening effect. Such mixtures are able to penetrate concrete and cement to a depth of 10 millimeters, giving the floor base a high strength and durability, as well as preventing the formation of dust. It should be noted that the majority of construction materials in this category have different antiseptic and biological additives that prevent the formation of mold and fungus, as well as protecting the base from harmful insects.

Mixtures for concrete floors

Priming for a floor made of concrete should have the following characteristics

• Great penetrating ability;
• After hardening, the surface must be perfectly even;
• In the composition of the mixture there should be special additives, giving concrete protection from aggressive environmental factors;
• A good primer should reduce the amount of material needed to fill the floor.

If you take into account all the factors described above, then the ideal solution for priming floors in a residential building will be "Betonokontakt". The composition of this mixture includes quartz sand, so it can be used for both starting and finishing works. If the screed was filled from high-quality cement, which has high strength, then an alternative option as a primer will be various epoxy solutions.

When priming floors in the bathroom, bathroom or bath, it is necessary to use mixtures containing water repellent and antiseptic additives.

Building mixtures for priming wooden floors

Primer for a floor from a tree is selected by other criteria, than screeds from concrete or cement. In most cases, alkyd, phenolic and polystyrene primers are used for wood impregnation. It is also possible to use oily mixtures and natural resin trees, which perfectly penetrate the tree and create an excellent protective layer.

If you want to make a floor made of wood that will last a long time, special primer and antiseptic agents should be present in the primer to prevent the formation of mold and fungus, and also protect the wood from ants, termites and other insects.

It is worth noting that for wooden floors to use a mixture of deep penetration there is no point, because unlike industrial premises on the floor will not create large loads. Therefore, it will be sufficient priming with any finishing mixes, which are intended for impregnation of wood.
