A matt blackboard paint, suitable for all porous surfaces such as stone, wood, plaster, etc. The paint forms a strong surface that is resistant to wear. After 48 hours the paint is waterproof and can then be wiped off with a damp cloth. The paint spreads very easily. This creates a very smooth surface that is suitable for writing and drawing with chalk. Make sure you apply the paint to a grease-free surface. No primer required. Apply 2-3 coats and allow to dry for 30-45 minutes between each coat. Apply the paint with a soft flat brush or smooth roller and clean with warm water. Coverage: 7 m²/L.
