Many homeowners use blackboard paint in the kitchen, utility rooms or play rooms. While blackboard paint is typically painted over wood or plasterboard, it can also be painted over glass. Applying blackboard paint to glass is easy to do and does not require the use of a painting primer. In just a few short hours you can transform a piece of glass into a functional blackboard.
Clean the glass with a cloth. Remove any dirt and debris from the glass. Dry the glass with a dry cloth.
Lightly rough up the glass with fine-grit sandpaper. Wipe away the sanding dust with a damp cloth. Dry the glass with a dry cloth.
Tape off the area where the chalkboard paint will be applied with masking tape.
Apply blackboard paint to the glass with a paintbrush. Coat the entire glass area with the paint. Remove the masking tape immediately after painting. Let the paint dry as per manufacturer directions.
Prime the blackboard by rubbing the side of a piece of chalk over the entire surface. Wipe off the chalk with a blackboard eraser. After priming the glass, you can use the blackboard as normal.
