Thoroughly clean the wall that you are going to cover with chalkboard paint. Repair any holes or scratches on the surface of the wall.
Cover the edges of woodwork on the wall with painter's tape to prevent the primer and paint from adhering to the wood surfaces.
Coat the wall with a layer of stain blocking latex primer according to the directions on the product label. If you are using a spray chalkboard paint, consult a professional salesperson to see if the primer is compatible with it. Allow to dry thoroughly according to product instructions.
Paint the wall using a roller, sponge brush or spray can. Coat the wall with an even layer of good quality chalkboard paint. Add a second layer for a longer-lasting surface.
Dry the chalkboard paint for at least one full week before conditioning it for use.
Condition the chalkboard painted wall by rubbing a piece of chalk over the surface. Hold the chalk between your thumb, ring finger and pinkie to apply it horizontally to the painted wall. Rub chalk over the entire surface.
Wash the conditioning chalk off of the chalkboard paint surface with a damp cloth. It is now ready for use.
