How often do you wonder about the need for certain events during repair at home? I will never do something if I do not understand why it is generally necessary. And once again, deciding to paint the walls of your room, and not to punish the wallpaper as usual, in front of me, I got up completely explained by the question: why do you need to grind the surface during the preparation of walls under painting? To understand this question, a longtime friend, and a part-time professional painter, Vadik. Since the coloring of various surfaces today is one of the most popular design options, I will talk about the technologies of working with your own hands and choosing a primer for concrete, plastic and drywall.
Grinding for walls
Objectives of the use of primer solutions
Independently sting the walls under painting
In fact, the primer plays a big role for high-quality repair in his home. It is due to it that it creates the opportunity to extend the life of the finish and even improve its quality. It does not matter how much the way you purchased paint. If the basis for it was incorrectly prepared, no one will give you guarantees for a long service life. It should always be properly prepared by the walls, after which it is painted by various LX.
Vadik explained in detail to me why you need to apply soils for the walls, and now I share this information with you:
- The main advantage of using primers before painting is to improve the properties of adhesion, that is, the grip of paint or other finishing materials with the surface
- If there are particles from the wall of the wall due to mechanical exposure, the paint will not be able to cope with such a problem. That is why it is necessary to primitive the base, connecting these particles among themselves
- This event reduces the absorption property of moisture to the surface. Therefore, the primer is needed for plaster and putty
- Soil allows to reduce paint consumption during surface staining. It is very beneficial on the basis of the cost of the LKM
- Stains that cannot be removed from the walls can leak through the layer of paint, while the appearance of the finish is worsening. Thanks to primers, a film is created that does not pass such stains.
Important! Without priming walls before painting, you will have to apply the LX at a minimum of two, or even three layers. The ground, on the contrary, will allow painting the surface in 1 layer. So think about whether you should save on preparation to be embellished on the painting of concrete, plastic, plasterboard or metal surfaces.
- The use of water-repellent mixtures allows you to protect the surface outside the house or in bathrooms, where there is always a high level of moisture
- Anti-grapple protection, which is available in many mixtures, protects the walls not only from the negative effect of water and moisture, but also from the concomitant manifestations of mold.

Thanks to fungicidal additives, the soil not only prevents the fungus, but also fights with it on damaged areas
Preparation for water-level paints and acrylic primers
Grounding for walls under painting
Acrylic primer is used before painting wood. Due to this composition, the protection of wood increases against negative influencing factors. Like other species, the acrylic mixture can significantly reduce the flow rate of the paint or varnish used, if you have doubts, I count before painting, how much you have to use LKM, when applied in 3 layers and in 1 layer. From the difference you can take away the cost of the primer composition and get your savings. The acrylic mixture can be applied both by spraying and paint brushes.
If you decide to arrange the walls of water-level paint, then applying the soil before painting is considered a mandatory procedure. You can choose a soil for walls on an alkyd or water basis, in any specialized store, the sales consultant will help you decide on paint and soil.
Important! Staining Water paint walls are very common, due to the simplicity of application and low cost per paint material.
The use of primer in front of the waterfront paint has its advantages:
- Improves the strength of the coverage and service life
- As the adhesion usually increases
- Significant reduction in paint consumption
If you are blunting the ceiling, then you need to use a brush, not a roller, since the second tool will not allow you to get to hard-to-reach places. The peculiarity of staining with water-level paint is that it consists of particles of polymers, which evenly dry out only thanks to the soil layer.
Preparation of concrete bases, plastic and drywall
Ground the walls under painting with your own hands
Preparation of walls from concrete is also a mandatory event before staining or other types of finishing works. Due to the high level of porosity, concrete is able to absorb a large amount of moisture, which further accelerates the process of material destruction. Primer creates a protective layer for concrete, preventing excessive absorption of moisture. In addition, due to the smoothness of the coating, the adhesion of the walls with paint decreases, only the soil can solve this problem.

Choosing an antiseptic composition, you can protect the surface of concrete or drywall from the manifestation of mold and fungus. For the floor of the concrete you need to take polyurethane soil, and for the wall - acrylic, organic or water based. As everyone knows, for staining drywall, not only priming, but also to put the surface. Having spent putty work, pick up a small penetration soil, which I said earlier. As part of such mixtures there are antiseptics. For the surface of the drywall, it is important before making paint, remove all dust and dirt.
The main difference of plastic on other bases is the property of elasticity. That is why the soil must be special for him with good elasticity. Many car enthusiasts are chosen for plastic soil Kaparol. Having a white color, it can be written on your own to the shade you need. Let's consider the advantages of this soil for plastic objects:
- There is a possibility of modeling
- Almost odor
- After complete drying, you can grind the surface
- Environmentally friendly
