How to turn your surface into a blackboard

Before you start

Make sure your room is above 10°C and open a window to keep it ventilated. Cover anything you don’t want to get paint over.

If your surface is in good condition, just give it a light sand with 240grit sandpaper. This’ll help the paint stick.

How to prepare previously painted surfaces

If the paint is flaking or cracked, you’ll need to sand it off. Use 120grit sandpaper to do this. Remember to wear a face mask. Vacuum any dust and wipe with a damp cloth. Repair any holes or cracks with our Multi Purpose Wood Filler. Be careful preparing any surface that was painted before 1960, as it may be coated with lead paint.


Give it a really good stir. Then apply with a synthetic brush, make sure you apply an even coat and finish brush strokes in one direction. A second coat may be required if painting onto extremely porous substrates i.e. bare MDF. Allow 4 hours between coats.



Take off as much paint from your brush or roller as you can. Then wash them in warm soapy water. Don't empty any leftover paint into drains or watercourses. Your local authority may have special ways to get rid of unused paint. Protect from frost.
