Whether the wall coating is sprayed or rolled
Brushing, rolling, and spraying (including air jet and airless spray) are common methods for wall paint construction, and should be selected according to specific conditions and effect requirements. Rolling is the use of roller construction, is a matte effect, the effect is similar to the wallpaper, so-called brushing, rough surface, knurling, texture, texture refers to this type of effect. It is recommended to use a short-haired roller for home decoration. It is easy to operate during construction, the pattern is relatively shallow, and it is easy to take care of daily; the large texture of the long-haired roller is easy to hang gray, and the small background such as TV background wall and corridor background is also very Pretty. It is recommended to confirm the required effect in the inconspicuous places behind the door before the large-area construction. When the drum is used, it can be diluted with little or no water. The brush is constructed with a brush and is a flat effect, but the brush will leave a brush mark. Home improvement generally uses a wool brush, which is softer and can minimize brush marks. The proportion of water added during painting is controlled between 20-30%, not more than 35%. Above this dilution ratio, problems such as powder removal, sag, floating color and bottom leakage are prone to occur. The spray is constructed with a spray gun, the surface is smooth and smooth, the hand feel is very good, and the fullness is good, which is the best plane effect. Divided into air spray and airless spray, the final effect of the construction is the same, but the paint film is thinner (20 microns at a time), it takes several steps to achieve better results; The airless spray film should be much thicker (up to 60 microns at a time) and meet the construction thickness requirements at one time. The dilution ratio of air spray is similar to that of brush, and the dilution ratio without air spray varies from machine to machine, generally less than 20%.
