Got an area above a window were the backing plaster blew due to laths comming away from lintel. The centre of the lintel has droped slightly due to being 1930's. Would I be better of boarding it, then dot'n'dabing it to enable it to disguise the sag. The thickness off the plaster would allow for this. I am also wondering if pvaing the lintel would work. I know that plaster a wood don't mix, but is this the same with plasterboard adhesive? Also doea anyone know how long it takes for backing plasters to seperate from wooden back grounds. Are we talking years or decades? Ciao
