HELP!! Blown Plaster

digital_biscuit

HI All

Been stripping paper and paint off walls in our bedroom-to-be and it seems that we have two places where the plaster has blown!! One area, the largest, is about the size of a fist, could this be fixed with filler or does it need re-skimming? Also, if it can be fixed with filler do I have to remove all the plaster that isnt firmly attached to the plasterboard behind it as one side is still intact, just not fixed to the plasterboard!

Thanks for any help!!! I am in the bad books with the OH as she wanted to use lining paper!!

You should really remove any loose plaster and then either fill it or reskim depending on how big the gap is.. it doesn't sound too bad if its not much bigger than a fist , I've had blown plaster where I've had to hack off loads and then reskim. If you tap the wall you can usually hear a different sound where the plaster is blown.

Anything that isn't attached to the plasterboard needs to come off.

You can use easyfill if the area is small, don't use polyfilla etc..

I'd personally get the area reskimmed, a plasterer would know what can be salvaged and what needs to come off.

And lining paper wouldn't help if you just papered on-top of blown plaster (so you're ok there )

i had this with my house, i ended up taking it all off, the parts which didnt just pull off came off with minimal effort with a chisel.

if its that bad it might be better take it all off.

I had some patches that were up to about 8" across and I was able to fill and blend in to the surrounding plaster. Anything larger, and I had the wall skimmed. As krisdorey says, don't use Polyfilla, use Easifill. And allow small areas to dry overnight before painting, longer for bigger areas. It does tend to shrink, so you might have to do two coats.
