Good, effective and easy-to-use paint for walls makes surface finishing a simple task that anyone planning a repair can take on.
Before you begin, it is worth familiarizing yourself with the basic information about applying paint and varnish coatings. Which wall paint is best for myself? How should this be used? One of the most convenient products for painting walls is latex paint.
Latex spreads very well on the surface of the wall and usually creates an intense, deep color that retains its properties for a long time. When considering various coatings with synthetic latex binders, pay particular attention to professional latex paints.
Latex has properties that affect:
- labor safety - latex binders do not contain harmful solvents and plasticizers, which, when painting and drying the walls, can release irritating substances;
- durability - they create flexible coatings that are resistant to wet cleaning, so that the walls look good even a dozen years after repair;

What latex paint to choose?
When choosing latex paint, first of all, consider what effect you want to get on the painted surface. Emulsions differ in resistance class, which is divided into five levels.
Classes I and II are characterized by the highest mechanical strength. They work well in polluted interiors, such as the kitchen or bathroom, in sunny places and on the ceiling.
They are ideal for wooden surfaces, i.e. furniture and panels. Depending on what effect you want to achieve, choose a paint with a matte, semi-matte, satin or matte surface.
How to paint the walls with latex paints?
To get started, select the right work tool. Latex paints can be applied in three different ways.
During repair, use:
- Roller - rollers with a rather short pile work best. As a result, the paint does not drain. You can also apply latex paints with a roller from a string;
- Brush - choose a brush with synthetic bristles, which is ideal for applying all water colors. A brush with natural bristles absorbs paint too quickly;
- Aerosol - uses an airless device - do not forget to set the appropriate parameters. The spray angle should be 50 ° and the pressure should be between 150 and 180 bar.
Which work tool you need the most depends not only on the type of paint.
If you are waiting to paint a wall with a large surface, it will be more efficient to use a roller or spray (after applying other equipment). Latex paint in the corners of rooms, around windows, furniture and radiators, however, it should be applied using a properly profiled brush.
How to prepare the base of the wall for latex painting?
The wall on which the product will be applied must be dry and clean to increase the adhesion of the paint to the substrate. So, if you decide that the walls in your house are poorly prepared, you will have to prime them.
Pay particular attention to:
- absorbent and dusty coatings and gypsum putty;
- gypsum and lime-gypsum plasters,
- walls made of gypsum elements;
- concrete and aerated concrete walls.
How to apply paint?
- When opening the paint bucket, mix the product thoroughly to obtain a uniform structure. Then follow the instructions.
- Dilute the first layer with water so that it makes up a maximum of 2% of the total amount of solution (per 10 l of paint with 200 ml of water).
- Apply the paint to the wall in a wet manner so that subsequent strips of the resulting coating overlap.
- Wait about 2 hours until the first layer dries - after this time it should be dry and warm. If you feel that the paint is still cold, wait longer with a second coat.
- Apply a second coat to the wall without further dilution and apply the same application method. Wait for the paint to dry completely.
- Also pay attention to issues related to room temperature. Avoid situations where the temperature in your home is above 30 ° C. Then the latex paint may dry too quickly, making it less durable and unevenly distributed.
