Construction method of water-based paint for interior wall;

Painting the wall finish is a very important part of home decoration and the last step of wall construction.

Project environmental requirements

Different coating types have different requirements for the construction temperature, which should be controlled according to the temperature in the product description. Generally, it should be between 10 ~ 35℃, and the minimum temperature should not be lower than 5℃; When coating construction is carried out indoors in winter, heat preservation and heating measures should be taken.

Selection of coating methods for wall topcoat

There are three commonly used wall painting methods: brush painting, roller painting and spray painting. When decorating, after weighing the advantages and disadvantages of various painting methods, choose the most suitable painting method according to your own preferences.

Advantages and disadvantages of step-by-step application

Brush coating is the most primitive, generally simple, saves paint, is suitable for various shapes and paint varieties, and has low efficiency, and is not suitable for quick-drying coatings. If the operation is not skilled, the paint film will produce brush marks, sagging and uneven painting.

Roller coating is suitable for large-scale construction, with high efficiency, paint saving and small color difference. The decoration is slightly poor, and uneven roller marks are easy to appear in roller coating.

Spraying is suitable for brushing high gloss paint. Spraying speed is fast, smooth and delicate, and corners and gaps can be well drawn. Compared with spraying, it costs paint. In addition, if there are bumps, the color difference of repair will be more obvious than roller coating.

How to level the wall

Wall leveling also affects the final effect of the whole wall painting. Whether it's a new house or an old house, the wall can't be completely flat, and the angle of yin and yang can't be completely vertical. Therefore, the uneven wall should be leveled with plastering gypsum, so that the error of the wall should not exceed 3 mm. If the angle of Yin and Yang is not straight, plastering paste is needed to keep it straight with a ruler.
