Wall painting with water-based paint
Among the many products intended for painting walls, a special place is occupied by water-based paint, the technical characteristics of which provide a reliable, beautiful and safe surface coating. There are three main types of water-based paints:
- polyvinyl chloride;
- latex;
- acrylic.
The first type is used for painting dry rooms, the last two - in rooms of high humidity. Painting the walls with water-based paint contributes to the creation of a harmless, durable film that allows air and water vapor to pass through, that is, the wall “breathes”. In more detail about the composition and advantages of this material read here.
Correct painting of walls with water-based paint
The surface of the wall, which will be covered with water-based paint, must be carefully prepared and primed. It should be perfectly smooth, without dents or scratches, since after painting the wall, especially with glossy paint, all the flaws will be especially noticeable.
To paint the walls with water-based paint, you will need the following set of tools:
- paint roller with interchangeable nozzles;
- flute brush;
- a bucket for mixing;
- tray (tray) for paint.
It is desirable that a thixotropic water-based paint is chosen for painting, the technical characteristics of which ensure the absence of drips on the walls. Such paint adheres well to the hairy roller and brush, without dripping from them. Before proceeding to work, you should check the quality of the brushes and the roller, which should be clean, without residual old paint. New brushes should be checked by pulling on the pile: it should hold tight. If the tools are of poor quality, then painting with water-based paint will not give the desired result: on the walls there will remain stains that have come out of the brushes of the villi. Since painting the walls with water-based paint should give them the desired color, the paint is pre-tinted. For this, the purchased white paint is poured into a plastic bucket, water is added if the paint is too thick, carefully mixed with a nozzle on a drill, adding the selected coloring pigment.
Aqueous paint can be applied to the walls with a brush, roller or spray gun. In most cases, a paint roller with various nozzles that create a textured surface is used for painting. The walls are painted from top to bottom with a paint roller. The width of the vertical strip should be about 0.5-0.7 meters. Each subsequent strip should go slightly to the previous one, about 7-10 cm. A water-based paint is recommended, the technical characteristics of which show good hiding power.
To obtain an evenly painted surface, the wall should be painted quickly so that the new strip does not dock with the strip of already dried paint. For one run with a roller, an area of about one square meter should be treated. To achieve uniform color, one wall should be painted in one go, without interruption. For an even, high-quality coating, two coats of paint should be applied. The second layer is applied after the first is completely dry.
