    What can I do with blistered paint?

    Painters & Decorators

    What can be done about blisters on paint in a living room? Does it depend on the type of paint, wall surface material, or/and extent of the blisters? Would it cost much to have a professional fix this?

    "Scrape paint and rub down back to solid paint seal with a stabiliser or Zinsser peel stop and fill once dry with easy fill sand and repaint."

    "You'll need to sand the bubble down and then fill any gaps, cracks or holes and repaint. You may need to use a primer first if the sanding goes down to the plaster and if you have a damp problem in the wall, you'll need to treat that before priming and painting.
    If the wall/room has been newly repainted, you can just work on that particular patch but if it's an old paint job, it's best to repaint the whole wall or even better, the room."

    "Hi. Blisters normally occur if the undercoat hasn't been allowed to dry before the final coat is applied.

    You can sound it down, apply some PVA at a ratio of 5 parts water to 1 part PVA.

    The following day you can re-paint.

    The cost for a professional would depend upon the area involved.

    Regards,

    Mel"

    "What I would normally do is scrap back the paint to bare plaster approx 100mm past the affected area.
    Fill and sand feathering in the filler

    However, depending how severe the blisters are this can be caused by not having a mist coat on the new plaster causing cracking and blistering

    If this is the case then all the paint should be stripped off and a miss coat applied to the plaster"

    "It all depends on what paint it is and if on woodwork or walls and if on the wall is the paint over wallpaper or over old paint or even on new plaster. Someone would need to see it to quote"

    "When I decorated my new flat I sanded walls to get a nice level finish then used tough washable paint that kids couldn’t damage and is going strong. Older Paint does flake but newer ones seem to have been designed to last longer and so far so good.
    The cost of material was not much and the time for 2 coats was about 2 days
    Per room.
    Hope that helps"

    "The first thing to do is eliminate what's causing it. By scraping away the paint and revealing the plaster or surface that's been painted first, you can then do a PH test this will tell you what chemically is going on. From there you can assess and find out, how to deal with the problem. Because all painting starts with prep and then the right primer etc.
    For example...
    If the PH of the surface, wall, woodwork is alkali, you need to prime with an anti-alkali primer first of all.
    You can also after scraping the paint off use Zinsser Gardz on drywall ...that's just one there are lots of them.
    Price
    That would depend on the size of the wall."
