Large Bubble found in ceiling - Help

coops1975 · 2 Nov 2006

Hi

Just noticed a Large bubble found in the ceiling, at first I thought somebody may have put there foot through it, but upon closer inspection and by pushing with my finger it looks like the redish plaster is coming away from the plaster board.

My questions are

Should I remove all of the painted ceiling plaster that has come away? I think so but I am unsure?

Second, What should I use to fill the thin plaster with ?

Will something like polyfiller multipurpose do the job ?

Cheers for all advice in advance

Is the 'Plaster Board' bare ? i.e. no paint coatings on it ?

coops1975 · 2 Nov 2006

yes, underneath the painter ceiling layer, yes the plaster board is bear as I can see where the nails hold up the plasterboard to the ceiling

Hope this answers your question

Sorry Third Eye

The plaster board is underneath and the plaster has been applied over this and then painted on top of the plaster.

There is no paint between the plaster board and the plaster layer.

The painted layer is what you would see when you look up at the ceiling.

I hope this help, many thanks for coming back

Many will disagree and some agree, however, i personaly believe that gyproc should be sealed prior to Plastering. However, the Plaster that has blistered can be caused by many reasons which i will not get into. Best thing to do is scrape off blistering plaster then dust off with a dry brush, then apply a coat of PVA @ PVA 1/5 Water mix on the blistered area gyproc and leave to dry, then apply another coat and leave to dry, then apply a mix of Gyproc Jiont filler and apply with an hawk n trowel and use a straight adge to keep the filler at the same depth of the surrounding plaster and leave to dry, then apply another coat and apply with an hawk n trowle and use a straight adge to keep the filler at the same depth of the surrounding plaster and leave to dry, then rub down in order to blend in with surrounding plaster. Then paint using correct emulsion and follow instructions..................However, hopefully the rest of the plater does not start to lose adhesion !

Many thanks for your help. Had to look up the word Gyproc but I found the filler.

Cheers
