Hello everyone first time on here as I have problem which I need your help with. In my lounge I have blown/live plaster on about third of a wall vertically the width of lining paper. I recently repointed the bricks outside and now no damp is finding it way through to the paper lined plaster. I have removed some of the lining paper and the plaster and cement behind that is crumbling and much of it has reverted to a dust like substance-can I use PVA mix to stabilise the remaining cement on the wall which is left behind the actual plaster which I have removed, and then buy some ready mixed skimming plasterto replace the old plaster? You will appreciate that I need to make good the wall to achieve a good bond for the repair. The house was built in 1931. thank-you all Miles Dexter
yes by all means use pva to seal the plaster,you mentioned the cement render has crumbled as well,I recommend you use limelite plaster to fix the problem.
