How to primed the walls for painting?

Primer is called the basis of high quality, which is used for a variety of finishing works. Use of this material is necessary in order to remove dust, dirt or degrease the surface.

  • The main tasks of this material can be called degreasing, dedusting, as well as providing high adhesion for surfaces thatare subject to processing. In addition, the priming of walls for painting provides the possibility of uniform application of coloring compounds and glue. Priming can be safely called an indispensable part of quality repairs.

    Why the priming of walls

    is necessary. The primer covering the surface allows to save paint coatings due to the increase of adhesion. This provides additional durability and water resistance to all products that are strengthened with it.

    Protecting treated surfaces from bacteria is also another challenge with which primer blends successfully cope. They contain special additives that prevent the multiplication of various harmful organisms. And if the appearance of mold was noticed in the room, then do not forget to walk on it with an antibacterial primer, and you will get rid of it with a high probability.

    In principle, it does not matter what type of work will be performed, the treatment of the walls with a strengthening mixture can be called an indispensable stage if you have to put the tile, paint, etc.

    Surface types

    Typically, when doing repairs, paint drywall, plaster, wallpaper for painting. Despite the fact that the plaster is a moistened coating, ready for subsequent finishing works, experts recommend priming it before applying the paint. This is due to the fact that the surface treated with a primer will not crack and crumble, due to the reinforcing polymer components.

    In addition, plaster is a porous material that can absorb a lot of liquid and therefore priming will help reduce the consumption of the coloring material.

    Types of primers

    Modern manufacturers of building materials offer consumers a huge number of different types of primer mixes, which differ in their characteristics, depending on the purpose.

    Depending on the field of application, the primers can be divided into several varieties:

    • alkyd( used for surfaces of wood and metal walls);
    • acrylic( universal and perfectly suited for a variety of surfaces);
    • aluminum( used only when working with wooden surfaces);
    • polyvinyl acetate( used only before the application of paints and other coatings having a special composition or for priming concrete surfaces, wood or plaster);
    • silicate( used for processing sand-lime bricks or decorative plasters);
    • epoxy( used if necessary deep impregnation of concrete surfaces).

    Based on the classification given above, it can be noted that before choosing a mixture, it is necessary to determine the material of the surface that will be processed.

    How to choose a primer

    When choosing a primer, you need to pay attention to the manufacturer, the cost and the accompanying characteristics of a technical type. The deeper is the level of absorbency in the substrate, the better this material will be to achieve any goals.

    The most common and often used form of such a mixture is an acrylic type primer. It is a universal material, can be used to prepare walls for painting with water-based paint and is ideal for all types of work both inside and outside the premises. And if you do not know which primer you best choose, take the universal one.

    Preparation and necessary tool

    The method of applying the mixture is universal and does not differ in any way from the application of other finishing materials. Immediately before the application of soil, any surface is cleaned of the old coating, cleaned, sanded, and also degreased. It is worth noting that the number of approaches priming the walls is always strictly individual, but it should be done at least two times.

    For primer application you will need:

    • roller;
    • brush;
    • atomizer;
    • capacity.

    In each individual case and for each specific task, various tools can be used. For example, you can apply the mixture on a brick surface with a brush, but on flat walls or plasterboard walls with a roller.

    Pulverizer is also an excellent tool for solving such problems, but is used less often, since after its use it is quite difficult to wash the entire room.

    How to primed the walls for painting

    The priming of walls before applying water-emulsion and any other paint is a mandatory step. The best option for this type of work can be called the use of a universal primer. A universal mixture has all the necessary properties and can be perfectly suitable for processing a wide variety of surfaces.

    Primer for painting the walls is applied in a certain sequence:

    • primed;
    • shpaklyuyut;
    • primed a second time.

    First of all, some solution is poured into the pallet, in order to facilitate the quality of future work. Roller is rolled in capacity, and excess material is removed using a special container.

    Do the work carefully. When priming the wall, the mixture consumption is calculated at 150 ml per 1 sq.m. After applying the layer, it makes sense to wait a bit and only after 30-50 the level of absorbency of the wall will be understood. Only after this, it will be possible to accurately understand how many layers are best used for the qualitative strengthening of the wall. After the primer has completely dried, you can start the process of painting the walls.

    It should be noted that when performing repair work and before painting surfaces, it is necessary to treat walls with a primer. But it needs to be done correctly and only by that kind of mixture that will be as close as possible to the material from which the walls are made.
