How to block stains from showing through paint or wallpaper

Before you start

Our stain block works best if your room is above 10°c. Open the doors and windows for added ventilation and put down dust sheets to protect your furniture from paint. Always wear a mask to avoid inhaling the fumes.


  1. Shake the can until you hear it rattle and then carry on for another minute.
  2. Hold the can 20-30cm away from the wall or ceiling and spray from side to side for an even finish.
  3. Wait 10 minutes for the first coat to dry.
  4. Apply a second coat and wait 10 minutes again for it to dry. After the second coat, assess the stain and apply a third if it’s still visible.
  5. Wait 24 hours for the paint to fully dry before decorating over.


Wait until the paint is completely dry before you cover it with paint or wallpaper. This isn’t intended to be a top coat, so you should cover it.


To clean the aerosol, turn the can upside down and spray it for a few seconds. Wipe the nozzle with a damp cloth.
