    Hi lads,

    The folks are painting one of the rooms in their house and the paint that they're painting over is peeling off when applying the new paint.

    The wall was originally painted with a matt paint but the new paint is soft sheen. Is this what the problem is?

    Would anybody know how to go about stopping the old paint peeling off?

    Any help and advice greatly appreciated.

    Thanks.

    Was the room used to keep a tumble dryer in or is it damp?

    No, no tumble dryer.

    I don't think it's damp either. Its a stud partition separating two rooms. The other side of the wall is being painted as well but they're not having the same problems with that side? I'm open to correction but if it was dampness would it not be effecting the other side?

    Thanks for the reply.

    The paint that was used in that particular room might have been bad.

    Usually if the paint is peeling off, its due to damp or condensation on walls.

    Using sheen over matt would not cause this.

    Yeah it's possible the paint wasn't the best.

    Is there anything you would recommend to solve the problem?

    Your going to have to scrape all the flaky stuff off I'm afraid, there's no other way around it.

    There's only certain parts of the wall that are flaky. When these areas are flaking we scrape if off back to the skim finish but when we paint over it you can notice the parts that were scrapped away compared to the parts that were okay and it looks awful.

    If you can understand that is there anything you would recommend Michael?

    Thanks for your help so far. It's been very friendly.

    I'm afraid the only thing you can do is scrape it back to a solid edge. Fill it with polyfilla (may need a couple of fills). Then sand it back. And touch up the patches with emulsion a few times.

    One last question, after I scrape it back to a solid edge, fill it in and sand it, do you think I should polybond the wall?

    No way.

    You can get owatrol that goes into emulsion for flaky walls. Ask for it in your local paint shop.

    If you thin the paint you're putting up a little it won't 'pull' as much at the old paint. Probably take an extra coat but save a lot of frustration at the same time

    The plaster is very dry where the paint is peeling back. Its a straightforward solution. Scrape and sand all the loose paint off. Add 20% water to the first coat on the exposed plaster. when dry flush fill around the areas where you can see a difference in the paints. Once the filler is dry, sand it smooth and touch up with the watered down paint. You may need to fill it again at this stage. The key with filling is to build it up in layers as opposed to putting a load of filler on. Once you've finished sanding the filler, touch it up again with the watery paint and leave to dry. When dry paint out all the walls as normal. Job done.
