На сегодняшний день существует огромное a variety of materials for the arrangement of premises. The primer is a special building material that is intended for the primary processing of various surfaces before performing basic work. It helps to improve the performance characteristics of other materials, increasing their resistance to the effects of negative environmental factors, and extends the life of building materials. You can buy it in specialized stores at an affordable price and from reputable manufacturers.
When flooring is very important to perform thempriming so that they are warmer and the flooring lasts much longer. Therefore, many people are interested in the question of what kind of primer self-leveling floor is better. In this article you will learn about the main varieties of this building mixture and their differences.
Why is it necessary to ground the floor?
Lay the flooring directly onconcrete screed is not recommended, because it practically does not interact with other materials and does not adhere tightly to them. In addition, voids remain in the concrete after solidification, which significantly reduces the strength of the concrete. The only solution to all problems is priming. However, in order to achieve the desired result, it is very important that the primer for the floor was of high quality.
What does priming the floor?
Priming the floor gives the following result:
- quality of adhesion of concrete with other materials increases;
- increased performance characteristics of the screed;
- concrete becomes more resistant to negative environmental factors;
- disappear various defects made when casting screed.
If your house has wooden floors, then a primer for the floor, the price of which varies from 480 rubles. up to 3500 rubles for 10 liters, allows:
- significantly save on paints and varnishes;
- hide various wood defects;
- prevent the formation of mold and mildew;
- improve the quality of adhesion of wood with other materials;
- extend the life of the floor;
- prevent resin from shedding wood;
- create an excellent waterproofing floor;
- protect the tree from harmful insects.
Thus, priming the floor, regardless of the flooring used, is mandatory if you want to get a quality floor.
How to choose a primer: manufacturers, reviews
Today, the following primer manufacturers can be distinguished, who have earned the trust of consumers: Caparol, "Miners "Ceresit and Knauf. Based on customer reviews, the primer from the "miners" is the most economical option. As for brands Ceresit and Knauf, they belong to expensive manufacturers, but the quality of the material is at the highest level. About primer Caparol can be heard only positive reviews. Its price perfectly matches the quality.
Alkyd Primer
This kind of primer is used.exclusively for impregnating wooden floors before painting. This mixture contributes to a significant improvement in the quality of adhesion of wood with other materials. It should be noted that primed wooden floors should be at a temperature of indoor air of at least 15 degrees. It takes 15 hours to dry completely.
Acrylic primer
Грунтовка для пола этого типа, как нетрудно 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 removes any defects and significantly increases the strength and durability of the screed. In addition, acrylic does not emit any toxic fumes and odors, and also dries completely in just 3 hours.
Shellac Primer
Glyphthalic primer
Another kind of mortar,intended for priming wooden floors. It is intended for preparation of wood for impregnation by epoxy. Before buying this primer, you should consider the fact that it can only be used in dry conditions. After impregnation of wood the floor is left for a day for complete drying.
Perchlorvinyl primer
This primer for the floor, the consumption of which is veryeconomical, is almost complete analog of acrylic mixtures intended for use in industrial facilities. It is strictly forbidden to use it in residential premises, since the substances that make up the primer are hazardous to human health.
Polyvinyl acetate primer
Phenolic primer
The starting mix possessing very sharp and unpleasant smell which is applied on any types of surfaces before laying of wooden floors. It takes about 12 hours to dry completely.
Polystyrene primer
Universal primer industrial type.Due to toxic fumes released during the drying process, it is not used in rooms intended for human habitation. Used to perform the starting work in the preparation of wooden and cement foundations.
Polyurethane and epoxy mixtures
This primer polyurethane floors is designed for application to concrete substrates. It is made by adding solvents to various coloring matter.
General recommendations for choosing a primer
Primer in front of the self-leveling floor should be carried outwith the help of starting mixtures with high penetrating power, in the composition of which there is glue. It helps to improve the performance characteristics of concrete and cement, as well as extends their service life. If fire retardant or alkali is present in the cement screed, the primer must be alkaline.
If you are already at the final stagefill the floor and are going to start laying the flooring, in this case it is worth using a finishing primer. This should take into account the compatibility of the mixture with the type of your screed.
Если вам необходимо подготовить какую-либо surface to adhesion with other materials, which was previously painted, in this case, the universal mixture will not work, and the only solution would be a primer for deep penetration to the floor. When choosing a particular mixture, its compatibility with the composition of the screed should be considered.
When performing repair work to strengthenOld screeds are also recommended to use primers with deep penetrating ability, having a strengthening effect. Such mixtures are able to penetrate into concrete and cement to a depth of 10 millimeters, giving the foundation of the floor high strength and durability, as well as preventing the formation of dust. It is worth noting that most of the construction materials in this category contain various antiseptic and biological additives that prevent the formation of mold and mildew, as well as protect the base from harmful insects.
Mixtures for concrete floors
- high penetrating power;
- after hardening, the surface should be perfectly flat;
- as a part of the mixture there should be special additives, giving the concrete protection against aggressive environmental factors;
- a good primer should reduce the amount of materials needed to fill the floor.
If you take into account all the factors describedabove, the ideal solution for priming floors in a residential area will be "Betonokontakt." The composition of this mixture includes quartz sand, so it can be used for starting, and for finishing work. If the screed was cast from high-quality cement with high strength, then various epoxy solutions would be an alternative option as a primer.
When priming the floors in the bathroom, bathroom or bath, you must use a mixture containing water-repellent and antiseptic additives.
Construction mixtures for priming wooden floors
If you want to make a floor of wood, whichwill last for a long time, then the primer must contain special fire-fighting additives and antiseptics that prevent the formation of mold and mildew, as well as protect the wood from ants, termites and other insects.
It is worth noting that for wooden floorsuse a mixture of deep penetration does not make any sense, because unlike industrial premises on the floor will not create large loads. Therefore, there will be enough priming with any finishing mixtures that are intended for impregnating wood.
