Hardwall Meets Plasterboard on External Corner

Postby Dickyp234 » Mon Jul 25, 2016 5:23 pm


Long time reader, first time post..

I have recently dot and dabbed a chimney breast wall with plasterboard. When pulling out the old fireplace surround it pulled off some plaster on the corners and on the perpendicular walls and has gone back to brick.

I have levelled the plasterboard with the level of plaster on the side walls (i will skim theses walls and the main chimney breast wall) but in places there is a lip where the old plaster has come off.

Will it be ok to use hardwall in there and level it up with the edge of the plasterboard?

Forgive me for asking a stupid question but from my understanding hardwall won't bond to plasterboard so should I expect to see cracking on the corners or will the bead hold it all together?

I have thought about using bonding but won't I have to PVA the bricks?
