How to Fix Old Chalkboards
- 1). Lightly sand the chalkboard to remove any chips and glossy surface area.
- 2). Clean the chalkboard. Mix the water and soap together at a 10 parts water to 1 parts soap in the bucket. With the rag, apply the soap and water solution to clean the chalkboard. Let the surface dry.
- 3). Apply a thin, even layer of primer onto the chalkboard. Use the nap paint roller to apply the primer. Let the primer dry for at least two hours.
- 4). Stir the chalkboard paint thoroughly with the paint mixing sticks.
- 5). Apply a light, even coat of chalkboard paint on the chalkboard with the nap paint roller. Wait four hours for the first coat to dry. Apply the final layer of chalkboard paint. Let the final coat dry for three days before using the chalkboard. Wait seven days after painting the chalkboard before cleaning it down with a damp cloth.
