Never paint the walls on rainy days

Renovation lasts a long time, so it is inevitable to encounter rainy weather. Can you paint the walls on rainy days? Why is it said that you should never paint walls in the rain?

1. After the wall paint is painted, there will be a film period and a drying period. Under normal air humidity, these two processes are almost synchronized. However, if the air humidity is greater than 85% and the moisture content of the base layer is greater than 10%, it will be difficult to dry and the film will not be formed well. Later, the latex paint wall will become powdery.

So, never paint the wall in rainy days, as it will affect the formation of the paint film.

2. Putty must be applied before painting the wall. It usually takes 1-3 times, during which the normal drying time is 1-2 days. But in rainy weather, you must extend the drying period and wait patiently for 2-3 days or more before proceeding to the next step.

3. Not only can you not paint walls on rainy days, but you can also not paint wood products. Because wood materials are highly absorbent, they will become damp in rainy days, which will greatly affect the paint layer. appearance and service life.
