Varieties of primers for the floor: how to choose?

Today in the shops of building and finishing materials you can find different types of primers, designed for different reasons. Recently, high-quality flooring compositions have become very popular, since with their help one can not only level the surface with waves and differences, but also provide it with enhanced waterproofing characteristics. Today we will talk about the existing varieties of floor primers.


Primer is one of the most common and sought-after finishing materials. It is used for different purposes. Consider them in more detail.

  • Using a quality primer, you can level the surface of the subfloor. Many finishing materials (for example, porcelain tile, laminate, parquet, tile or linoleum) must be laid on a prepared base. To achieve the desired effect, it is simply impossible to do without soil.
  • The primer is often laid on a cement screed. Due to this tandem, cement foundations become more pliable in operation. Laying on them other coatings becomes much easier.
  • Finishing flooring materials that have been laid on the substrate, covered with soil, have a longer service life. This effect is achieved by increasing the degree of adhesion of the coatings. Due to this feature, the finish is not subject to the formation of cracks, chips or delaminations.
  • Concrete floor surface becomes more durable after treatment with primer. Therefore, many consumers during the repair rush to strengthen the floor base with high-quality primer. Without it, concrete over time can break down.
  • The primer is designed to protect the base of the floor from aggressive chemicals. Few people know that dampness and substances dissolved in it are able to penetrate the putty for various reasons. Often this leads to chemical reactions that have a detrimental effect on the finishing materials. With the help of high-quality primer mixture such problems can be forgotten.
  • The primer can significantly save on subsequent finishing materials, because it closes the pores in the base structure.
  • It is necessary to preserve the natural moisture level at the base. A surface that has not been trimmed with a primer is, as a rule, overdried or too damp, and this has a very detrimental effect on the durability and strength of the floor base.
  • Special priming compositions with a high degree of moisture resistance are often used if the floor heating system is present in the room. Such mixtures are often used before laying tiles in rooms with a high level of humidity (kitchen, bathroom, bathroom).

I need a primer to prevent dust from accumulating on the base finish. It is a very useful addition to the subfloor. Due to her base and decorative material will serve for a long time, without causing any hassle.

Today, in stores you can find a good alternative to glyphthalic primer - zinc-rich mixtures.


This two-component mixture is most often used to design concrete foundations. With it, the base surface can be made more durable, reliable and durable. In addition, after applying the epoxy composition the floor becomes more moisture resistant. Epoxy mixtures are often used as a separate layer. They have high adhesion.

  • Do not forget to prepare the foundation for the future application of soil. It needs to be dried if it is raw. In addition, from the floor you need to remove all debris, dirt and dust.
  • Grind the substrate if necessary. After this cleaning should be repeated.
  • It is necessary to prepare the mixture, based on the instructions that manufacturers indicate on the original packaging. If you do not want to mess with the dry composition, you should purchase a ready-made mixture that does not need to be prepared for finishing work.
  • After that, you need to dip the roller into the container with the prepared soil. Apply the mixture on top of the cleaned base until dust has settled on it.
  • First, the roller should be led parallel to one of the walls, and then perpendicularly (along the same wall). Such an application is considered the highest quality and most convenient.
  • After that, you should properly grease all the corners in the room. You can use a brush. We should not forget about the joints that are between the floor and the ceiling.
  • In no case do not miss any areas of the floor during the processing of the soil. Too much primer should not be applied too.
  • Soil is necessary to cover the entire area of ​​the rough floor base. After that he needs to be allowed to dry and then apply a repeated layer of the composition.
  • If it is inconvenient for you to work with a roller, then you may well use a special brush with a long handle.

Security measures

Working with any primer mixture, we must not forget that it is a chemical product. Experts strongly recommend the use of thick gloves when working with such compounds. Try to avoid getting the solution on open skin. Sometimes the masters do not manage with ordinary gloves - they specially acquire paint overalls. To some people, they seem inconvenient, but in matters of security, this defect is not so important.

Do not forget that many types of primers are quite difficult to wash off from different surfaces. If you accidentally stain your hands with such compounds, they will remain dirty for several days. Polystyrene priming compositions are rightly recognized as the most toxic and hazardous to health. It is necessary to work with them especially carefully and prudently. In no case do not finish the floor with such a mixture in a completely closed room. Experts recommend that you always wear special masks and the highest possible gloves when working with polystyrene primers.
