I have a large room with 3 red brick walls and 1 plasterboard wall. The brick walls are fairly straight, do I need to get them bonded 1st or is it possible to multifinish straight on to p.v.a-ed walls?
If the answer is no could you briefly explain why not? many thanks in advance

Hi,
You cannot apply finish plaster to a bare brick wall.
The walls no matter how good condition they are in must be rendered or have a floating coat(undercoat plaster such as thistle browning) applied before finishing.
The main reason for this is that finish simply will not cope with the various salts etc etc in the wall, and also a skim coat will not cover the indentations of a bare brick wall, it is far to thin.
Under no cicumstances put finishing plaster straight onto these walls........!
PLEASE....
