Water is used to mix plaster.




Change your handle to DANGERMAN.

If it was vinyl, how can it be remedied?

Hi, on my way to work so cant offer you help at the moment, but will PM you later with advice on how to sort this, as I think I know what your problem is, and have come up against this a few times.:D

paint the wall with NEAT pva (not expensive ) and then paint again with paint mixed with pva
this will also repel moisture

That will be a serious source of future peeling.

will it not peel off like PVA does on plastic?

Yes

no it will anchor it to the wall. make sure all loose is removed first though !

No it won't. PVA will NOT seal the plaster. It will sit on the surface. When the new emulsion paint hits it it goes "live" again, loses adhesion with the wall and in due course it will peel again.

Never PVA new plaster before painting.

A mist coat (highly thinned) must be used on all new plaster or you can have problems, vinyl is a definite NO also.

A vinyl paint can be used for a mist coat but the plaster MUST be very, very dry first. Contract emulsion is best for a mistcoat. Never use Rich Matt - that doesn't stick.

I redecorated my bathroom a few years ago and have had nothing but bother since and am looking for some advice on how to remedy it.

................................. snip snip ................

I have no idea how to remedy this and am loathe to let another painter charge a fortune to not be able to fix it. Short of getting the wall replaced is there any product that can seal the wall or make the paint stick?

If not, any suggestions about a moneysaving way to fix this problem. thanks

Peeiling paint is normally down to one of three things:

1. The plaster wasn't prepared first by applying a proper mist coat.

2. The plaster had been previously papered and not all the paste had been removed

3. Some numpty has PVA'd the wall.

4. The plasterer overpolished the wall.

I suspect you have a combination of at least two of these here although as I haven't seen it so its very difficult to be certain. It looks to me as though the solution is:

1. Clean it all off (paint, paste, PVA whatever).
2. Lightly key the surface.
3. Paint with an oilbased undercoat or specialist Primer like BIN and leave it to dry completely.
4. Overpaint with your emulsion. Use quality trade paint not branded stuff from the sheds and avoid "specialist" bathroom and kitchen paint. Its all marketing hype.
5. As an alternate use eggshell rather than water based emulsion.

We have this problem too, but it's only on two walls. The paint is peeling off the 'outside walls' . We live in a Council house and have contacted them many times, but they are not interested, saying its our fault. We have had this problem for at least 5 years and we just don't know what else to do. We keep the bathroom door shut while we cook and we have windows open all day. Any help would be apreciated, thanks.

Is it possible to let us all know what the problem is as it may well help others reading this.

Cheers.
