Plaster, Paint and Cracks,

[DisasterZone]

Hi Guys and Gals,

Bit of advice if you could.

Over the last six months i have been looking at a crack in my bathroom ceiling. I replastered the whole lot about three months ago but, the plaster started to "bubble" a few weeks ago.

I have taken the newly applied plaster off and took the advice from elsewhere on this forum and filled my hairline crack with some caulk so i don't have to replaster again.

However, when i attempted to apply Polycell crack free paint yesterday (to the old plaster) it immediately stuck to the old plaster and within seconds peeled away whilst i was using the roller. It was like peeling away a separate piece of paper from the ceiling ie. it didn't adhere at all.

Any advice would be greatly appreciated.

I usually do things myself by more often than not it ends up taking 6 times as long and costs 3 times more than calling someone in. Why i bother i do not know!!!!

Cheers all

Just a thought - did your caulk contain silicone? (Caulk containing silicone can't be overpainted.)

I'm not sure although it claims it can be overpainted so i assume it doesn't.

The reason it flaked off is probably because its far too thick to be applied over a porous surface..(filler) try thinning it out a fair bit irst of give it a coat over ordinary emulsion..(thinned by about 20%)

Doubtful that the combination of the two will solve your problems though

Caulk wont hold a ceiling together..if its a bad crack and deep you need to find out whats causing all the grief.

Cheers bud,

Have just thinned out some emulsion and that has adhered. Will do the thicker coat the weekend,

Cheers
