The latex paint wall is dirty, and everyone will think of changing the color to make up for it. So can I brush latex paint directly when changing colors? Actually, it depends. If there is not too much foaming, mildew, peeling and other phenomena in the original latex paint wall at home, you can brush latex paint directly. However, it is necessary to polish the wall slightly with sandpaper in advance and clean it up, which is convenient for brushing latex paint and changing color.

Bubble is the phenomenon of water leakage and damp caused by building structural problems. First, scrape off the bubbles with a knife and wipe them off. When using gypsum dry powder to plug the gap, it is not necessary to fill the wall, which is as low as about 2 mm below the wall. Then wait for the air to dry before applying latex paint. When it is air-dried, you will see good results.

Moldy also needs to be smoothed with sandpaper to remove moldy parts. Then use putty to polish the uneven places, then use a scraper to scrape them flat until they are naturally dried, and then use latex paint to color them. You can achieve a good color change effect, and its quality is relatively stronger and tougher.

If the wall is dirty because of water seepage, the first thing to do is to check where the water seepage is at home and solve it. Then the part of the wall that oozes water will be cleaned up and removed, and the wall brick and cement will be visible. Then repaint, repaint latex paint and pay attention to prevent the room from leaking again. In addition, it should be noted that the wall paint is easy to empty when it meets water. Don't do some high-temperature things on the wall, such as smoking and cooking, which will easily lead to the second discoloration of the wall.
