Painting walls is a good and inexpensive way to change and refresh the appearance of a room. It is often mistakenly believed that a new coat of paint can simply be applied over the old paint, but this does not guarantee a long service life of the painted surface and the desired final result.

How to paint walls
Brush selection
When choosing a paint brush, you should consider the type of bristles.
- Synthetic bristles are durable and last up to five times longer than natural bristles. They are suitable for water-based paints.
- The natural bristle brush has a structure that allows it to hold the paint. The split ends with natural bristles help to achieve a perfect result when using solvent-based paints.
Roller selection
Large surfaces are best painted with a roller. As with brushes, it is best to choose a roller that is most suitable for the type of paint you are using. A short-pile microfiber roller is suitable for applying a smooth emulsion, while a medium-pile roller is suitable for a matte finish.
Important! Before use, remember to wash the roller in warm soapy water to remove lint.
How to paint walls correctly
Before painting, it is necessary to allow cleaned, damp surfaces to dry completely. It is recommended to choose a primer and topcoat from the same manufacturer. A hard, matte latex paint is well suited for painting plasterboard surfaces. Alkyd paints are suitable for painting walls made of boards and wooden planks.
What to do before painting walls
Before you start painting the walls, you need to perform several important preparatory tasks:
You should also:
- Remove curtains and blinds.
- Remove everything from the walls, including shelves, lights, picture hooks, and mirrors.
- Remove all nails and screws to make the surface flat.
Items left in the room should be covered with plastic wrap, and the floor should be covered with newspapers.
How to prepare a wall for painting
Before you start painting, you should prepare the walls. To do this, we recommend following these steps:
STEP 1. Sand the surfaces
Fill small holes and cracks with quick-drying putty. It is often necessary to apply putty in two layers, as cracks may form when drying, in which case the first layer of putty must be sanded. In bathrooms where the humidity fluctuates a lot, a special moisture-resistant putty is used and the surfaces are treated in accordance with the instructions of the paint manufacturer.
STEP 3. Clean the walls
Before painting, the work surface must be flat and free of dirt. Heavily soiled areas can be washed with soap or technical alcohol, but it is advisable to use a special cleaning agent that prepares the surface for painting. It is also necessary to carefully remove dust from the walls and ceiling with a vacuum cleaner .
STEP 4. Prime the walls
When painting walls, it is important to prepare the entire surface with a primer, which provides better adhesion for the next coat of paint. Apply the primer to the wall and leave to dry for two hours. After two hours, apply a second coat.
How to paint with a roller without streaks
The technique for painting walls is basically the same as for ceilings. Edges and corners can be pre-painted with a brush or narrow roller to make it easier to paint hard-to-reach areas. Next, you need to finish the areas around sockets.
The walls should be painted one by one. You should start from the top, moving down, then horizontally and finally from top to bottom.
When painting, do not allow the paint to dry too quickly, as the end result may be uneven.
