“Bought two 5L tubs to waterproof a wall and 2 chimney stacks at parents' house. Coverage was excellent and the product soaked in very well. After 24 hours it left no residue or discolouration on the brickwork. I used a roller for some of it but a brush for most (best for getting into the pointing). In fact it went so far I took one of the tubs home with me unused, to do a wall here. Fingers crossed no more rain ingress.”
