I use it on all reskims, I can get the client to paint it on for me. Then go in and just have a easier day on it. I did use pva but some walls pulled in quicker then others, with blue grit it all goes off together? Plus will be a guaranteed key!
Working now and blue grit is not blistering as much duno why. I put a thick 1st cost fairly smooth and few blisters appeared and then with second coat too k most of em out. I think the trick is to put a thick 1st coat on.
I've just used my refina spat to trowel up n it's gone in nicely guna wait another 10mins after this msg then use SP trowel in a couple of times.
Then a dry MT at end, wish me luck lol
