Hi there,I have a damaged section of plasterboard where sections the paper are ripped after removing the wallpaper.Should I seal it with Zinnser Gardz to stabilise the plasterboard ,or can I use a PVA solution?I undersand the Zinnser Gardz dries hard,so can I plaster straight on top of it or add a pva solution to make it tacky before plastering.
Thanks
Thanks
