Hi all. I've got an internal opening through a thick stone wall. I've built a frame to plasterboard sides and help out the aging lintels, but need to finish to the old plastered wall.... As you can see in photos it's, er, far from plumb!
Will filler stick to expanding foam? Could I potentially shape the foam and then fill?
Any other ideas gratefully received!
