Ronseal One Coat Damp Seal in white, 2.5 litre, is a brush-on damp stain blocker for interior walls and ceilings. It is the one to reach for when a damp patch keeps showing through your paint.
Ronseal says it brushes straight onto damp patches and permanently covers damp stains so they cannot ruin your topcoat. No preparation is needed and you can paint straight onto the wall, as long as it is not dripping wet. It is ready to paint over in four hours, so you can finish the job in a day. This 2.5 litre size covers up to 12.5m², a handy low-priced fix. Sort out the cause of the damp first, because covering it up will not cure the problem. Once the seal is dry, finish with your usual paint or wallpaper.
