British Gypsum said that only Universal One Coat was the only product that would be guaranteed to be used on that type of block. It was hollow terracotta from Poland. I think the customer thought they were saving money when buying it. It's 3 years into the build & not even half done & my guess is there's at least £200k been spent on it so far. They've went through builder after builder with this project. I said I'd try a day with the stuff. Never again. I said to go back to BG & ask if it can be dot & dabbed. If so, I'll do the rest of the build
It's got to be dot and dabbed looking at the state of the walls, never used one coat...
