Levelling Plastered and Plasterboarded Surfaces
by Mike Sullivan
I attach a photo showing the other side of my infilled doorway. How do I get a crack free join between board and plaster where I have removed the angle bead? Its very rough( I have only done this on this side wall the other three are still intact.
Apply diluted PVA to the old plaster. If the wooden frame is properly prepared as previously discussed there will be no cracking, as long as there is no movement, and as long as you properly push the plaster in with firm pressure. The PVA will not only help the plaster stick, but will also help control the suction. Apply 2 coats to be sure.
