Thompsons One Coat Damp Seal White 2.5Ltr 4.3 5 9 9
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
Does what it says on the tin using again having used before with exceptional long lasting results compared to similar products 3 Oct 2014
Excellent Product Surprisingly easy to apply. I used a roller and obtained a good solid smooth coat. I was very impressed with the final result. Good and solid in a few hours and proved to be an excellent base for emulsion. The only warning on this is that the stated coverage is somewhat optimistic. I used 2.5 litres to cover a 5m wall. That's about 5m² per litre, not the stated 7m². Certainly did the trick though and was well worth the expense. No sign of any marking to date. This is an excellent, easy to use product. 27 Aug 2014
