The roof of my house is leaking, and the top of the wall is moldy after waterproofing. How long does it take to dry? Can latex paint be dried without shoveling?

In your case, it is very likely that the leaking roof wall did not dry completely when redoing. After painting the wall finish, the water in the wall will not volatilize, and water vapor will form on the wall skin. If it is wet for a long time, it will become moldy. If you want to do it thoroughly, you must shovel off the brushed latex paint and waterproof putty, so that the exposed wall can be dried four months after it is dried in summer. Wait until autumn, then make a wall.

Note: Be sure to scrape off the wall paint to dry.
