Is it okay to put PVA solution on light weight blockwork before internal S/C rendering?
When I've used s+c on thermals I've just gave the brickwork a good dampen down and let the scratch coat fully cure, ,I know a few lads use a cement sbr slurry or use fibres in the mix there's different ways personally I don't think pva is needed on the blocksThat's what the architect spect. I wanted to do it in hardwall. I'm really trying to establish if Pva solution would cause failure in bond. Thankfully the walls doesn't sound hollow when you tap them.
