What's happened to my ceiling :-(

Soubrette

About a year ago we had the ceiling in our bathroom replastered.

We had to wait for it to dry and then paint it with watered down paint twice before covering it with a normal coat.

In the end we had to cover it with 2 coats of watered down paint and 3 coats of normal coat. We used a specialist bathroom ceiling paint which was waterproof.

A few days ago I noticed a few flakey bits over the shower (it's a cold damp old house and had no fan) so thought we'd better look at that this weekend, but in the last few days it is much worse with bits flaking off to the plaster. In all there is a line about 10cm long which is flaky which ends in a patch about 2cm square of which some has flaked right off.

This weekend we are going to sand it back and reapply the paint - as there is some bare plaster, should we water it down again? Or just apply the normal coat of paint? Will this just keep happening (2 adults and 2 older teens all taking showers every day)?

Why isn't anything ever easy, you think it's done and something else crops up

I'm no expert, but how long did you wait between applying the watered down paint and the normal paint? We're just had our kitchen walls and ceiling skimmed and will be painting it with watered down paint when all of the plaster looks completely dry, then leaving it about 6 months to paint it with normal paint.

Perhaps you didn't leave it long enough. You especially need to be careful with vinyl/water resistant paint as that doesn't allow the plaster to breathe.

:eek::eek::eek::eek::eek::eek: 6 months Why? lol thats crazy, once the plaster is dry ( no dark bits) paint it with watered down paint then just use normal paint, use trade stuff and it will go in 3 coats, 1 thin and 2 normal.

as for why your paint is flaking off i dont no there are lots of reasons just sand down and touch up then when it drys,hit it in again, job done

We just did what the plasterer told us to do madget - wait for the plaster to dry, put a couple of watered down coats on then paint with normal paint until a nice even cover is achieved, waiting for each coat to dry in between.

Curly - should I use normal paint now - or use waterdown stuff first?

Thanks

yes just use normal paint now.
condensation can get behind any paint surface and ruin it. bathrooms and kitchens are the worst by far.
make sure you have adequate ventilation in the bathroom. esp when the shower/bath is operating. that will help stop any further problems.

even opening a window will help.

That's what the kitchen people and plasterer have advised, curly. We were also told to wait the same amount of time when we first moved into our new-build house. Maybe because some of the plaster isn't skimmed - some areas have quite a lot of filling with plaster on top?

Curly

never herd of it in my life :S

when u move into new build your not supposed to touch it until the 1 year snagging is done because in this time all the water drys out of the house which means it gets a we bit smaller and moves which makes cracks and then it needs filled and painted

I too would have just have painted with thin layers of paint, until we moved into our current house nearly 10 years ago and a lot of the walls need replastering (the house was built in the 80's and had a mock tudor effect by having 3x2 pieces of batton all over the walls and ceiling and when you tried to take it out, it was held in with 6in masonry nails and brought chunks of the walls and ceiling with it). I was advised to seal the plaster with a layer of watered down pva. I've done this to every wall and ceiling and had no problems since. You can buy this on the adhesive section of the diy store. Its the white stuff that you used as glue in school. Hope this helps.
