Seen some rubbing up, once its cured get that eggshell cracking look, wondering what causes it? It hasn't happened us, but a few jobs I've seen, actually got a firm used to labour too, seems to happen them quite often. I was thinking maybe the scratch coat too strong causes it? For I mind at the time couldn't believe how strong they wanted the scratch. Normally I mix scratch at 16 shovels to a bag,
They wanted it 2 bags to 25. Thought that was unusually strong, maybe too strong, so if any movement in the blocks then the scratch coat just shelled underneath? Anyone know what normally causes it?
