How primed wall.

to repair the room with his hands, it is important not to forget about such an important event, such as priming the surface before painting or wallpapering.At the same time it does not matter what kind of material is the basis of the walls or ceiling, as well as some texture and shape is required to handle the site.Therefore it is necessary to further consider how to prime the walls and ceiling of the room properly.However, it is best to start with a mixture, is used as a basis, that is, directly to the primer.

What is priming?

This is a special part of the solution, whose main function - processing of varying the surface before applying the paint on it or wallpaper.Work with the primer is very convenient, since the material lies perfectly on any land, creating a kind of film on it.To understand why primed or that place, it is important to remember that without this dye solution can be absorbed very bad, and after the drying result can be far from ideal, because the surface will dazzle lines and stripes poorly applied composition.

Do not forget that there are several kinds of mixtures, so you should focus on the difference between them, the purpose of each of them and to determine not only how to prime, but it's better than doing.

types primer

in accordance with the composition to distinguish between lime, oil, alum, emulsion and other coats, so you should consider only the most common ones.

mixture on the basis of lime has a great range of features and is used as in the interior decoration and outside buildings.The main function of a primer - preparation for subsequent surface finishing brick and plaster or concrete.

Applying alum solution is not as widely spread as lime, as this material is suitable only for the preparation for adhesive application.

manufacture and storage of mixtures on the basis of copper sulfate is carried out strictly in wooden containers or containers made of plastic, as the steel tank can rust.This primer is applied to interior decoration, usually plaster, or coating the surface of concrete to subsequent adhesive or lime coloring.

oil composition as it becomes clear, is used only in conjunction with an oil paint, which is the main component of this mixture (the primer is required to dilute the varnish).

main purpose emulsion solution - diluting the thick consistency of paint.

What is priming?

Many owners during repairs often wonder about whether primed walls of the room, or you can completely do without this procedure.However, this work has two very important points, considering that, we can conclude that primed the wall before wallpaper or before painting definitely need:

  • this mixture allows the coating (wallpaper, paints, decorative plaster) a strong bond with the surface being treatedpreventing the emergence of a variety of visually recognizable defects;
  • using primer can be a special way to clean a certain area by getting rid of dirt and dust, thereby improving the adhesion properties of the walls and their absorption capacity.Due to these factors, paint or other finishing material can be applied freely, and the coating liquid is absorbed evenly and firmly join hands with the wallpaper wall.

Tools for priming

We must not forget that many priming mixtures are too toxic, so use them for the treatment of concrete surfaces is impossible.As a rule, the main types of solutions for walls appear acrylic, polystyrene compounds.

To understand how to properly prime the surface of one or the other, you want to first have available a specific set of tools required for the job.These include:

  • roller with fine nap;
  • small brush;
  • roller tray;
  • sponge;
  • bucket;
  • respirator (compulsory subject required when working with paints for compliance with safety regulations).

process of priming

Application fixing composition, as well as any other work on the interior design requires compliance with certain sequence.The algorithm is being primed or that the surface is as follows:

  1. For starters need to thoroughly clean the desired area from dust and dirt, and then wipe it with a sponge soaked in water.
  2. After this primer should be poured into a specially designed roller tray and begin to apply it to the surface.
  3. It is important to lay down a thin layer of the mixture, and the need to respect the proportionality, preventing the accumulation of a large amount of solution in one place, otherwise it can be a cause of divorce.
  4. Through small brush can be treated inconvenient places, such as corners, but it also should be monitored closely to ensure that the damage layer of the mixture was uniform.
  5. Prerequisite to the result of the work was positive - to the surface to dry.

Features priming drywall

Some owners are firmly convinced that it is not necessary to prime the drywall as he and so is flat and smooth.However, this is not true, since in that case, for example, by changing the wallpaper to remove the old coating can be achieved only with a part of the base gypsum.

Decide how primed plasterboard walls, it must be remembered that apply alkyd formulations prohibited because they can easily damage the layer of material.This will lead to the appearance of bubbles on the surface and peeling paper, which certainly will not have a positive impact on the reliability and quality of work.

Since primed plasterboard wall should be in a special way, and that the process can work to some extent, differ from the standard.It is important to pre-diluted in a basin mixture is applied with a roller from the top down throughout the area to be treated.Minimum application thickness thus should be 0.03 mm.

Drying time of primer

order to best facilitate the task of consumers, manufacturers usually specify the required time the primer is dry right on the pack, so just before priming the surface, you need to read the instructions.But in order to protect themselves from potential trouble, it is recommended once and remember these terms.

acrylic-based primer should dry for at least 3-4 hours, while oil solutions require the whole day.Furthermore, it should be remembered, and an optimal temperature, which should be about 25 ° C.The result is a good drying and, if such a parameter, as moisture will be equal to 65%.

Provided that the above values ​​are lower, then, accordingly, the time required for drying the mixture to increase by 2-3 times.The surface can be checked by touch, but too much trust in this method it is not necessary, since the minimum humidity primer may simply not notice, and to work with a wet basis, as we know, absolutely not.

Additional recommendations on the use of a primer

A variety of such mixtures allows you to buy absolutely any part of, for example, has an antiseptic effect and helps get rid of harmful microorganisms and mold.To perform the entire procedure, you must first process the desired surface with hydrogen peroxide or vinegar diluted in water, then leave for a while to dry.Thereafter a primer may be applied.With significant lesions wall fungus is allowed to repeat all manipulations again.

We should not forget that the mixture can be applied only on a prepared surface, which should be properly leveled and covered with reinforced mesh.It is important to get rid of any remnants of the old plaster.

If you plan to priming under the wallpaper, are heavy, the best solution is to purchase a part of the acrylic-based, which is not only well-align the desired area and prevent the formation of mold and mildew, but does not give bubbles appear and firmly hold the wallpaper on the wall.

Following all these guidelines, you can ensure reliable and high-quality coverage of any surface and forget about the need for any interior decoration.
