The paint machine is more expensive and the painter is generally not configured. The advantages of painting are: quick construction, good flatness, and poor texture. Disadvantages of paint are: paint loss, late maintenance trouble, because the late maintenance, the workers can no longer pull the painting machine over maintenance, can only use the brush, brush out with the texture of the spray is certainly different.

Brushing: Construction is relatively slow. However, the paint has a rolling texture and pattern and is easy to maintain. The disadvantage of brushing paint is that the effect of the big-faced roller coating is different from that of the inside corner and the inside of the lamp slot, and there is a difference in texture.
At present, many paint companies have promised to spray paintings for the owners free of charge, but they are basically not responsible for grassroots processing, and the primary treatment of latex paint is the most important because the grassroots problems directly reduce the final decorative effect of latex paint. In addition to the relatively large loss of paint, it is not particularly affordable.
â—† Seven Tips for Construction of Waterborne Coatings
The spraying method is one of the most important methods for the construction of water-based paints. A thin and uniform coating film can be obtained by coating the surface of the object with a spray method. For geometrical shapes, there are small holes, gaps, unevenness, and the coating can be distributed. Uniform; For spraying large surfaces, brushing is faster and more effective. However, with the spraying method, it is also necessary to master some operating techniques:
1. Use a clean water to adjust the viscosity of the coating to a suitable spray viscosity. Measured with a Tu-4 viscometer. The appropriate viscosity is generally 20 to 30 seconds. If there is no viscometer, you can use the visual inspection method: stir the paint with a rod (iron rod or wood rod) and stir it up to a height of 20 cm to stop it. If the paint is not in a short time (several seconds) Too thick; such as a break from the bucket on the edge of the line is too thin; to just stop at 20 cm high, the paint into a straight line, the instantaneous drop off into a drop, the viscosity is more appropriate.
2, the air pressure is best controlled at 0.3-0.4 MPa (3-4 kg force / square centimeter). If the pressure is too low, the atomization of the lacquer solution will be poor, and the surface will form pits; if the pressure is too large, the dripping will be easy, and the paint mist will be too large, which will waste the material and affect the operator's health.
3, the distance between the nozzle and the object surface is generally 300-400 mm. Nearly easy to hang; over uneven paint spray, prone to pitting, and the nozzle away from the object paint mist sprayed on the way to cause waste. The specific size of the distance should be appropriately adjusted according to the type, viscosity, and pressure of the paint. Slow-drying paint spraying distance can be farther, quick-drying paint spraying, the distance can be a little closer; thick viscosity can be near a little, when the viscosity is thin, it can be farther; when the air pressure is big, the distance can be farther, the pressure can be a little nearer; Closer to the farther point is the adjustment of a small range between 10 mm and 50 mm. Above this range, it is difficult to obtain a desired film.
4, the order of spraying is: first, after the first, after the outside. After the first height and then the low, the first small area after a large area. This will not cause the post-spray paint mist to splash on the sprayed paint film, destroying the sprayed paint film.
5, the spray gun can be used to move up and down, left and right, it is best to run evenly at a speed of 10-12 meters / minute, the nozzle should be straight to the surface spray, to reduce the oblique spraying. When spraying on the both ends of the object, the hand that deducts the trigger of the spray gun should be loosened quickly, so that the paint mist is reduced. Because the two ends of the object surface are often subjected to more than two times of spraying, it is the place most likely to cause sagging.
6, when the next spray to suppress a 1/3 or 1/4, so that there will be no leakage phenomenon. When spraying quick-drying paint, it should be sprayed in order. Spraying effect is not ideal.
7, when spraying in outdoor open places, pay attention to the wind direction (difficult to work when the wind), the operator must stand in the downwind direction, to prevent the paint mist from being blown into the paint film has caused an unsightly granular surface.
