Thompsons Damp Seal

Damp stains can be difficult to cover effectively as they will often mark paint that is applied, even after the source of the damp has been dealt with. A damp seal works as a barrier to prevent the stain from marking any subsequent layers of paint or wallpaper.

This Damp Seal from Thompson is specifically designed to seal damp stains with just one coat.


  • Colour: White
  • Size: 750ml
  • Coverage: Up to 7m²/L

Simple to use, this Damp Seal can be applied with a paintbrush.
