Rated 1 out of 5 by Cant Over paint Directly I can't comment on its performance directly as I have just applied it. I can say that I have not been able to over paint it with emulsion as it says on the tin. I have just spent the last hour scraping flaking dry emulsion of the walls that would not adhere to the Damp Seal. 15 Nov 2015
Rated 5 out of 5 by IT WORKS! I have a breeze block wall that is permanently stained. This paint has worked brilliantly so far. However, the wall was so bad that it needed two coats. It's a strange consistency, tried brush, gloss roller them emulsion roller. The emulsion roller worked the best, hands down. I now have a brilliant white wall that looks better than it has for years. 10 Jun 2015
Rated 5 out of 5 by Expensive but works This paint is really expensive, but it does work, I've used on a wall where a washing machine kept leaking and the damp was terrible and in an old closet. Painted nearly 5 months ago and no damp patches. Is really hard to paint on though with a brush. Use a roller. 1 Jan 2015
