Hello all,
I've just finished dismantling a built in cupboard in the boxroom. It's come out quite cleanly but with some plaster damage in areas (up to approx 15cm holes). The plaster is a solid surface coat with a kind of soft powdery grey substrate underneath with a texture somewhere between talc and sand - this goes back to the brick. I'd like to patch the plaster but the surface is pretty unstable, so a couple of questions...
Is this an old plaster method and if so what is it known as (apart from crap and annoying)?
Can I just stabilise it using some PVA mix and plaster onto it to patch it up and if not what should I do?
Cheers,
Buckie.

After just one coat it's miles more stable and more akin to stone than the sand it was before. I'll pop another couple of coats on it today and leave it till tomorrow and fill it in.
