Hi guys. I'm new to the forum so hello .
We have recently put a new timber extension to the side of our house.
We have used cement render boards to try and make it as lightweight as possible (white ones like aqua panels 12mm thick)
My plasterer is a bit old school and he sbr'd the surface of the board and put a base/ scratch coat of cement on and then a top coat.
Needless to say it has all fallen off as the base coat hasn't adhered to the cement board.
We are now not sure what to use...
External rendering over cement board. PLEASE HELP
