im rewiring a house where the plasterer has mixed the pva and plaster 2gether rather than pva the wall first. ive never heard of this. is this an acceptable method? some of the [plaster has started to flake away already
seems strange to me, normally the magical PVA is put on the walls first to help the gear stick, I wouldn't think mixing it in would be a good idea
PVA should be applied to the walls twice. It is used to seal the surface and to slow down setting time where the background will suck the moisture out of the plaster causing ot to dry out too quick and crack. Not to be used externally tho!!!!!!
i shud change my original post to ALMOST ALL of the plaster is coming away now! customer not happy at all!
