Is it okay to paint the wall in rainy days?

Although rainy days have little effect on wall painting, we should also pay attention to extending the drying time of the wall after the first painting. Generally speaking, the normal interval is about 2 hours, and the rainy days can be appropriately extended according to the weather conditions.

Many process steps in decoration have a "technical intermission time". For example, cement needs a 24-hour solidification period, and every time putty is scraped, it has to go through a drying period, and it can be scraped again after each drying. The paint also needs to be dried thoroughly every time before being brushed for the second and third time. Therefore, in rainy days, the intermittent time of this technology will generally be extended, so we must wait patiently.

Precautions:

1, for wood products, brush varnish or nitrocellulose paint when mixing oil. Try not to brush it in rainy days. Because a layer of water vapor will condense on the surface of wood products in rainy days. If you paint at this time, water vapor will be wrapped in the paint film, which will make the surface of wood products turbid.

2. If the painted wall is often exposed to the sun, it is easy to make the wall color fall off and the white wall turn yellow. In addition, exposure will also lead to heating of the wall, and the temperature of the wall will drop after painting, and the paint surface will crack. Therefore, it is necessary to avoid exposure of painted walls.
