Primer for walls: what is it for, its types and features
Priming is a necessary process for preparing surfaces before applying facing and decorative materials to them. The presence of such a mixture on the walls is a guarantee of high-quality and durable repairs without nuances. Why prime the walls, what should be taken into account and what are the features of primer mixtures?
Primer: what is it for, its types and features
Asking the question why the primer of the walls is needed, first of all it is necessary to understand what it is. A primer is a material, a specialized building compound, applied to walls, floors, ceilings and even the facade of a house.
The primer can be applied immediately before painting, plastering, wallpapering, tiling and other finishing work. Facing materials laid on high-quality soil hold better. The surface on which, for example, tiles are laid, becomes less dependent on the load. In addition, the primer reduces the consumption of glue, as it impregnates all the bumps and pores.
Another function of the primer is antiseptic. Modern mixtures allow you to prevent the appearance of bacteria, mold, microbes, fungi and more.
Depending on composition
Based on the materials included in the basis of primers, they are divided into:
1. Alkyd: applied to wood before wallpapering. Can be used as an antibacterial and antifungal;
2. Acrylic: Ideal for brick, concrete, wood and plaster walls. Has a fast degree of drying;
3. Epoxy: applied to concrete and metal coatings;
4. Perchlorovinyl: universal primer that penetrates wood, brick and bare plaster;
5. Mineral: performs well on concrete or brick walls;
6. Glyphthalic: used on metal coatings in dry rooms;
7. Phenolic: they should be used for facade and outdoor work;
8. Shellac: used on wood surfaces to prevent the release of resins.
Depending on functionality
There are four main types of primer, depending on the functions performed:
1. For impregnation: provides effective impregnation of the source material before applying the finish;
2. For adhesion: creates a layer between the base and the facing material, increases their adhesion to each other;
3. For deep penetration: the main task of such a primer is to penetrate ten or more centimeters to bond a loose, heterogeneous texture, increase adhesion;
4. Anti-corrosion: prevent the formation of rust on metal surfaces.
Why prime the walls before finishing and puttying
Why do I need a primer before painting and other finishing work? Let's look at this issue in more detail.
It is not enough to use good glue or high-quality, expensive paint during repairs. This will not guarantee a good appearance of the wall finish. A primer is also necessary in order to prevent wallpaper from peeling off and falling tiles, even distribution of paint, and so on.
Use this building material for:
• Creation of a flat, smooth surface;
• Strengthening walls before applying paint and wallpaper;
• Ideal distribution of paint materials without soaking into the wall;
• Shine;
• Protection against stains appearing through the wallpaper;
• Reducing the smell of paint after finishing;
• Use of light paint materials on dark walls;
• Prevention of mold, fungus and other factors.
Why do I need a primer before puttying? During repairs and when using putty, a primer mixture is applied to prevent cracking of materials. The presence of a primer layer is a guarantee that the wall will not absorb liquid from the putty, thereby causing it to dry out.
By applying a primer layer, the surface becomes more even. As a result, the consumption of plaster is reduced, as well as the cost of finishing work.
Rules for applying a primer coat
Applying soil to the walls is an important stage of repair, which must be approached with care and responsibility.
The scheme of its application is as follows:
1. The surface is pre-cleaned from dirt, dust and debris;
2. Debris is removed from the floor with a vacuum cleaner;
3. The liquid mixture is poured into the drip tray;
4. After wetting the roller in the mixture, its residues are removed, after which it is applied to the wall;
5. Application is made in one thin layer without pockets of accumulation;
6. The processing of corners and joints is best done with a small brush;
7. After application, the primer should dry out within a day;
8. If the surface crumbles, re-apply one more layer;
9. When it dries, you can start working on the surface.
Important! Do not dilute the entire mixture from the package at once, so as not to throw away the leftovers. In order to treat the surface of the walls with a composition, a small amount of soil may be needed.
How to choose a primer
When we figured out the question of why you need to prime the walls, it's time to choose the right primer.
For its selection it is necessary to follow several rules. Firstly, the primer material is selected depending on what tasks it must perform - prepare, level the surface, improve adhesion, protect against mold, and so on.
Secondly, an important fact is the location of the surface to be processed. Conditions of high humidity, temperature changes affect not only the quality of the finish, but also the selection of the necessary soil.
You need to pay attention to the surface on which the mixture will be applied. There are separate types of primer for wood, metal, gypsum, all types of concrete and more.
Particular attention should be paid to the types of surfaces to be processed. External, facade coatings need frost- and moisture-resistant soil. For this, options with deep penetration are suitable. For interior work, it is better to choose a primer with a minimal odor, for example, based on latex or acrylic.
