interior Painting newly built house ?
"josepea" wrote in message
om... I want to paint my living room walls. The house is newly built-only six years old. The walls were painted initially with what can only be described as a powdery matt paint. If you brush past the walls then you get the powdery stuff on your clothes ! I've tried to wash down the walls with sugar soap and some of the powder paint has come off revealing bare plasterboard.Any advice on how to prepare the walls for painting ? Josepea Wash down to remove majority of poor quality paint, as you have already tried in places. Then seal the walls by brushing on a primer coat of PVA/water mixed as per instructions on the can. PVA is available from most / all diy chains, builders merchants and even the local Wilko style places. Once the PVA has sealed the plasterboard then paint as normal. HTH, Jon |

I'm just wondering, is the all-curing PVA really appropriate for this application? I ask because I have recently had a whole house skim-plastered, which I followed up by painting the lot with 1:4 PVA prior to applying vinyl silk emulsion which I'm now doing. However, the PVA'd walls are now quite shiny and impervious and I have to say I'm a bit concerned how the emulsion is adhering to its substrate; doesn't seem that great to me. I'm worried it's all going to fall off. Previously I've used dilute emulsion to prime the plaster, which seemed to work better TBH. Blasphemy! Stoooone him!! I suspect you may have used it too neat. I wouldn't personally PVA fresh plaster, not really much point. Some people like to apply watered down emulsion first, I just paint it. Never had problems doing it that way. As for this situation, powdery surfaces are a real nightmare, and really the only way to cure is to stick it all together. PVA will do this well. -- Grunff |

Lobster wrote in message I've just been investigating my newly emulsioned paintwork further; there's little doubt that if you scratch at it, the paint readily peels off the plaster. Omigod. I've already done several rooms completely; looks fab, but clearly won't for long. I've had problems with Dulux emulsion. Crown is "thinner" but seems to cover and adhere better What are the panel's suggestions for the few remaining rooms, in which the newly skimmed walls have already been treated with 4:1 PVA? Is there a way I can undo its deleterious effect before painting? Sanding off a few microns and then doing it again with dilute emulsion? Yeeuch. IME a coat of 4:1 water/pva doesn't create a film over new plaster but subsequent coats may well do. In this case the first coat of paint should be applied sparingly so that it looks more like a wash. Once the initial bond is there the 2nd coat normally takes well. |

HTH, Jon I've justed visited Wilko and read the instructions on the back of their PVA. It actually says it is not suitable to be used as a primer prior to painting so now I'm confused ! Josepea |

Do you mean to dilute the first layer, or just brush it out very thinly (against mfr's advice on the tin, incidentally!) Thanks David |

Suck it and see really. Whatever it takes to get a film of some kind that you can't easily scratch off with your fingernail. Bear in mind that emulsion paint takes a couple of days to dry fully. As long as you can still smell the paint, there are solvents evaporating off and they're the ones to do with film formation and the eventual toughness of the paint. |
