Which is better to paint or spray? Shenzhen Curtain Wall Waterborne Ceramic Coatings

1. Painting with latex paint

For latex paint, the smoothness of the painted wall is not as good as that of spraying, and normally there will be left The painted flower print, if the painted wall looks very smooth, it is actually caused by too much water in the paint.

Adding too much water to the paint will reduce the adhesion of the paint, which is prone to paint peeling problems. At the same time, adding too much water will cause the paint to fade. When the content is reduced and the surface paint film is relatively thin, the wall surface cannot be well protected, and the elasticity of the paint is reduced, making it difficult to cover the fine cracks in the putty layer.

After brushing the top-painted wall, touch the white powder with your hands, you don't have to be nervous, most of the falling powder is Dust on the walls.

During the construction process, a lot of dust will slowly adhere to the wall, and it may appear similar after touching Powder phenomenon. Wipe the dust off with a duster or a clean towel and that will fix it. If the latex paint is of poor quality, contains too much water, and has less emulsion, the wall may be wiped with a towel for a year or two after painting, and the powder may fall off. It doesn't rub off when touched.

Second, latex paint spraying

The principle of latex paint spraying is to pressurize the paint to obtain high pressure through a booster pump (usually a plunger pump). The paint passes through the high-pressure pipe to a special high-pressure gun, and releases the pressure from the special nozzle to achieve the purpose of dispersion and atomization, and is applied to the object to be coated at high speed.

Because compressed air is not required for paint atomization, it is called airless spraying. This spraying technology was originally widely used in automobiles, aircraft, construction machinery, trains, ships, containers and other industries. With the continuous development of architectural coatings, high-pressure airless spraying technology is gradually applied in the construction industry, such as the spraying of latex paint, oil-based paint, water-based paint, resin paint, etc. and popularized abroad.

The advantages of latex paint spraying are as follows:

1. Excellent surface quality. The paint sprayed on the wall forms a smooth, dense coating without brush marks, which is unmatched by roller brushes.

2. The painting efficiency is high. The spraying efficiency of single operation is as high as 350-550 square meters per hour, which is 10-16 times that of manual brushing.

3. Delay the life of the coating. High-pressure airless spraying, which uses high-pressure spray atomization, enables the paint particles to obtain powerful kinetic energy and penetrate into the pores of the wall,  The paint film and the wall form a mechanical bite, which enhances the adhesion of the coating and prolongs its life.

4. The thickness of brush coating and roller coating is extremely uneven, generally between 35-200 microns, and the utilization rate is low. The thickness of the airless spray coating is uniform,   the thickness is about 35 microns, and the utilization rate is high.

5. Corners and gaps can also be painted well. Because the paint spray does not contain air, the paint can easily reach these parts.
