Hi all, I have a victorian cottage that has been added to over the years.It has solid,soft red walls. The chimney has been removed but the wall (no longer an outside wall) remains damp.The floor has been concreted.I have removed plaster to a metre high. What I need to do is to seal the wall and plaster/plasterboard the wall which will be behind kitchen cabinets.What I don't know is which product/plaster would be best to use. Some advise would be helpful. Thanks.
