please help - we have built mdf boxing in to cover the concealed cistern and pipework etc - no need for it to be waterproof - but used pva to seal it to be safe rather than sorry. Found that tiling was a problem and the adhesive wouldn't set. Would scoring the mdf mean that the tiles will hang properly? Or do we need to buy the waterproof cement backed aquaboard? and start again? At that crucial stage - so prompt responses would be great - many thanks.
