Question: how long do you have to wait for chalkboard paint to dry before using it?
Answer: You need to give it three days to dry. According to the P&G website, chalkboard paint should dry for up to three days before you use it. Then, when it's finally dry, you'll want to rub chalk over the entire space and then erase it thoroughly with a dry towel. Once you do this, the surface will be ready to go.
