High-pressure spray guns are not expensive and can be purchased online for about 300 yuan. It is common to find that roller brushes apply easily but erratically. The main advantages of spraying are very uniform, high construction efficiency (much faster than brushing) and good visual effects, soft and delicate feel, good quality, and wide application range. The disadvantage is that it easily pollutes the environment. When spraying, you should pay attention to the important issue of when to apply the latex paint. The advantages of painting are flexibility, simplicity and paint saving. The disadvantages are that it is easy to produce brush marks, sagging, low efficiency and uneven defects. The key issue of when to apply latex paint should also be taken into consideration when painting.

The spraying steps of latex paint are as follows:

1. First, determine the spraying time according to when the latex paint is applied, and then process the base layer. First, wipe ash and debris from the surface. If there is oil, wipe it with water or detergent. After completing all of the above, use putty to adjust the honeycomb, holes and residue on the wall, then use sandpaper to remove the excess putty after it dries.

2. Scrape the putty thoroughly on both sides. The putty should be as thin as possible the first time because it is smooth and soft. Note that the scraping standard for the second putty is the same as the first, but the direction of the second putty is perpendicular to the direction of the first putty.

3. When spraying primer, spray it on a dry, hard, clean surface, and keep the coating even during the spraying process.

4. After 4 hours of drying, you need to pay attention to repairing the first layer of the coating and entering the polishing process to trim the uneven surface. When a second intermediate coat is applied, a polishing process may not be required.

5. Shake the latex paint thoroughly before use, then open the container and stir evenly with a wooden stick.

6. When spraying latex paint on the surface, wipe off water splashes in time.

Things to note when spraying:

1. The spray gun range is large, difficult to control accurately, and dyed with other finished products, so the protection must be more complete and the protective film needs to be longer time.

2. Material loss is greater than painting material.

3. Later repairs are usually done by brushing, and there may be certain deviations in the repaired area.

4. If you use a variety of latex paint colors, the machine must be thoroughly cleaned to avoid color mixing.

5. Determine the reasonable spraying time based on the principle of when the latex paint is painted.
