How to prime a chalkboard before using it?
To prime a chalkboard before using it, first, clean the surface with a damp cloth to remove any dust or residue. Then, rub the entire surface with the side of a piece of chalk and erase it. This will create a layer of chalk dust that will help prevent ghosting when you write on the board. Finally, wipe the board clean with a damp cloth and it will be ready for use.
