Went to look at a job the other night 3 town houses having damping done, so they have chopped off metre high fair enough but then they have had a spread come in he scratch it then paint bitcumen over the top of the scratch coat!! i thought you paint in over the bricks and then chuck some sand over it as a key!! Its been lefted for 3 weeks like it and the bitcumen is like glass and as its waterproof i cant see anythin sticking to it am i wrong in my thoughts many thanks lads
