Hi Guys,
below my three shed windows is the same size gap which at the moment is a void, well covered in roof felt at the moment.
I am planning to cover these voids up with concrete board.
I am them planning to render these with a 4-1 mix.
My question is, do I have to put on a scratch coat first, or can I just top coat straight onto the board, also will I have to wet the board first
Regards
Dave
