Work With Primers

Selection and application of a primer for the floor

To improve the adhesion of the lining materials to the porous surface of the concrete screed, a special floor primer is used. Today in the market of building materials, you can find many such solutions, which differ in terms of application and composition.

mixture It may seem that priming of the floors is not an obligatory measure, since such a solution is rather expensive, and the result fromits application is visually invisible. However, if you refuse to treat the concrete floor with a special primer, then at the stage of finishing its surface you can have many problems that will significantly slow down the pace of repair work and lead to additional costs.

What does the primer do? After complete hardening, this solution creates a thin polymeric protective layer on the floor surface, which positively affects:

  1. Increased adhesion. The deep penetration soil completely fills the pores of the concrete screed, due to which the degree of adhesion of the lining materials of various types is significantly improved. No matter how many microcracks on the surface of the screed, the solution completely level the surface for maximum adhesion.
  2. Increased moisture resistance. A thin layer of the priming solution provides a reduction in the level of moisture absorption that significantly reduces the costs of adhesives during surface finishing and excludes the possibility of fungus formation under the facing materials.
  3. Integrity protection. Special primer for the concrete surface will significantly slow down the process of occurrence of microcracks during the operation of the finished floor.

Kinds of primers for the composition and application of

If you want to get a positive result from surface treatment with soil, then you should pay special attention to the composition of such a solution, its scope and basic characteristics.

  1. Alkyd primer. Such a solution can be used to treat a wooden floor. After complete drying, the ground makes the surface rough and slightly bulging, thereby maximizing adhesion to any kind of lining material. At room temperature, the primer dries for 10-15 hours. This solution does not contain harmful to human health components, so, if necessary, it can be used to handle any living space. In order to better protect the surface, it is necessary to apply at least two coats of this primer.
  2. Acrylic primer. The primer can be used for the treatment of a wooden floor, concrete screed, plaster and even plywood. The acrylic primer mix penetrates deeply into the base of the surface, completely filling the pores and providing a high-quality adhesion of any finishing materials. Such a solution is not recommended to treat metal surfaces, since it can provoke the appearance of corrosive processes. A deep penetrating primer for a concrete floor can be used for both new concrete screeds and for a surface that has already undergone insignificant damage. The acrylic primer dries for five hours.
  3. Glyftal Primer. Such a solution is used for the treatment of metal surfaces, but if desired, it can be used for a wooden floor at normal room humidity. The soil dries better at room temperature, and full hardening is achieved literally within half an hour. Most often glyptal primer is used to improve the adhesion of the surface with enamel paints. In addition, the composition of the solution includes coloring pigments, so that by correctly selecting the color of the soil, color rendition of the paintwork can be enhanced. How much such a primer will need for a full-scale processing depends directly on the state of the surface.
  4. Perchlorovinyl Primer. A solution of this type can be used to treat any surfaces, including metal and wood. At normal room temperature, the solution dries within one hour. It is worth noting that the composition of this protective coating includes toxic components, so it is undesirable to use it for the treatment of residential premises. The main advantage of the soil is its ability to stop the already begun corrosive processes.
  5. Polyvinyl acetate primer. Best of all, such a synthetic base primer is suitable for pre-treatment of surfaces before applying polyvinyl acetate dyes. The primer dries for thirty minutes. A deep penetration solution is used to protect a concrete screed, brick or masonry. The presence of color pigment in the soil provides enhanced color rendition of paint and varnish materials.
  6. Phenol primer. Priming compositions of this type are used for the treatment of wooden surfaces and the metal floor before subsequent painting. Considering how much such soil has in its composition harmful to human health components, it is not recommended to use in residential areas. At room temperature, the solution dries in 10-15 hours.
  7. Polystyrene primer. A deep penetrating primer mix that can be covered with a wooden or metal floor before applying lining materials or paintwork. The solution contains a large number of toxic components, so it is better not to use it for processing residential premises. Such a primer is more suitable for protecting a wooden floor on a porch, porch or other surfaces that are in the open air. How much you need such a solution for the full processing of the entire area depends on the state of the surface.

Priming the surface of the floor with your own hands

In order for the chosen primer for the concrete floor to fully fulfill its function, you need to carry out work on its application in strict accordance with the technology. Following the step-by-step instructions, you will perform the surface treatment very quickly and simply.

Preparation of the

tool In order for the priming process to pass quickly, you need to prepare in advance a set of specific tools that can be purchased at any specialized store. For a quality primer application on a concrete floor you will need:

  • a set of brushes of different width and shape for processing the most inaccessible places on the floor surface;
  • for high-quality screed treatment, it is better to use a roller with a long or short nap( depending on the type of priming solution);

    Rollers with long and short nap

  • for more convenience you also need to pre-purchase a special container in which you will apply the solution to the surface of the roller and brushes.

Cleaning the room

In order to obtain a high-quality result from a single application of the primer, you must thoroughly clean the floor surface from the smallest dirt and building dust. In this case, it is best to use a construction vacuum cleaner, which will completely collect dust from the entire surface area in just a few minutes.

Applying a mixture of

This stage is not very laborious, but very responsible, because the result of its implementation directly depends on how soon you can begin finishing the surface.

  1. If you bought the mixture in dry form, then dilute it with water at room temperature in accordance with the manufacturer's instructions. If you prefer a ready-made solution, then just open the bottle and pour some of the liquid into the prepared container.
  2. Next, you need to carefully handle all the corners of the room and hard-to-reach areas of the floor with brushes.
  3. The final step in applying the primer is to treat the main floor surface with a roller. Start applying the primer from the far corner of the door and gradually move to the exit, carefully painting each square centimeter.
  4. On average, the complete drying of the primer takes from three to ten hours, depending on its composition. Do I need to primed the floor again? Of course, it is necessary! After the applied primer completely dries it is necessary to apply a second layer of a solution of the same grade to create the necessary level of waterproofing and adhesion.

Conclusions: The priming of a concrete floor is an obligatory measure, which should be properly performed before applying the finishing coat. This is the only way to ensure a quality coupling of any finishing materials and significantly extend the life of the concrete floor covering.
