Ronseal Damp Seal Aerosol

Our One Coat Damp Seal permanently blocks damp stains on walls and ceilings. You can even put it onto damp walls. It lets trapped moisture escape without causing any more damage.

When it's dry you can paint or wallpaper over it. 

Before You Start

Make sure your room is above 10°c. Open your doors and windows for ventilation. Put down dust sheets to protects anything you don't want to get paint on and mask the surrounding areas to avoid overspray. 

Prep - Newly plastered walls: If you've had your walls and ceilings plastered, leave it to dry for 7 days. Then seal it before putting on our Damp Seal Paint.  

Prep – Previously painted walls: Get rid of any loose paint or plaster by giving it a quick sand. If you've got mould, get rid of it by using our 3in1 Mould Killer

Leave the paint to fully dry for 24 hours before you start to decorate.
