I do a lot of damp coursing in old brick houses and scratch with a 3-1 mix and top with a 4-1. But the house I am on at the moment has I kitchen extention out of a dense concrete block. Will my mix have to be weaker so it doesn't blow ?? Ta for any help
Too strong imo. It's all very well following specs to cover your back like but a lot of them are absolute bull.
Did anyone know gypsum won't guarantee any of their products on knauf or siniat boards?
I wonder why that is.......[emoji6]
Skim won't stick on MR board..[emoji42]
Need we go on?
