Rated 5 out of 5 by from Excellent product Thompson damp seal is a excellent product, I've had a problem with a damp wall & this seems to have cured it, it's quite thick but easy to apply & being a one coat it goes a long way, I have tried different damp seals in the past but this is definitely the best.

Rated 4 out of 5 by from Very effective I used this in a cold cupboard against an outside wall and it worked a treat. It is not the easiest paint to apply but I really only needed one coat .There is no sign of any dark or mottled patches coming through. I would definitely recommend it.

Rated 5 out of 5 by from Excellent product Very happy with this product. It covers all damp stains and stops them coming back. The only thing is that its very heavy/ thick to paint with, so used a good quality paint brush.
