Product Description

Venlac Flat Black with an ultra-hard, scratch resistant finish, allows you to create a unique writable erasable surface. Can be applied to wood, terra cotta, paperboard and hardboard. It is mostly used in school boards and for better performance Black Oxide should be added.

Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with a commercial detergent, or other suitable cleaning method. Rinse with fresh water and allow to thoroughly dry. Remove loose paint and rust with a wire brush or sandpaper. Lightly sand glossy surfaces.


Stir thoroughly. Thinning is not required. Use a good quality synthetic brush designed to give a smooth finish. Avoid excessive brushing or rolling. Use light, even strokes to ensure an even flow and the smoothest finish. Dries to the touch in 30 minutes and to handle in 2 hours. Fully dry in 2-4 hours. May be recoated after 4 hours.

After 3 days, the chalkboard finish is ready to use. Before writing, condition the surface by rubbing the side of a piece of chalk over the entire surface and erase. This will leave a coat of chalk dust that will provide the best erasability. Chalkboard can be wiped clean with a damp cloth. Wait 7 days after painting before wiping it down. Repeat conditioning step after cleaning.
