How to get reveals ready for plastering?

eamon11

Hello folks,

doing up an old house with 14 inch walls. The stone and mix they used in those days was very weak and when replacing the windows lots crumbled away. So I am left with very jagged and uneven reveals.

Any tips what to do? Idealy I wanted to use insulated slab here but there will be a hole behind some of the reveal and the stone protrudes too far out in places also.

Thanks for the replies.

Cut off the bits that stick out too far with a grinder. Fill in the bits that are too low with bonding...

thanks dilbert,

the prob is I have already covered the wall in 62mm insulated plasterboard which extends over these jagged and uneven reveals. Not so easy to get in there with a grinder or anything else. I was thinking of somehow filling up this uneven void with foam, but I would have to figure out a way of getting a straight even finish line of foam.
Can foam be plastered over?

Thanks again,

yes,foam is plastered over all the time.
