I've got a sound scratch coat up on my garden shed, it's hardened off nicely (10 days) Yesterday I started on the top coat and hit a problem, in places along the bell it's slumped and is really soft.
I have used bondit 3-1 and tried to use only just enough water to get a stiff mix but it's still slumping.
What are the problems using 3-1, have I over mixed or got too much 3-1 in the mix? It's strange that its only appearing on sections of the wall not along the whole.
I have been careful and gauged everything into the mixer 4-1 scratch, 5-1 finish and more waterproofer in the finish than in the scratch
Any ideas?
