Our house is quite old and was renovated (badly) before we bought it. It obviously should have been replastered in lime but wasn't and now we have patches where paint just won't bond to the walls and everytime it gets damp the paint lifts and falls off. Is it the paint or the plaster that's the issue?
Having the whole house replastered isn't an option at the moment so what's the best course of action to take?
I want to use chalk paint for breathability but if it's the plaster that needs to come off there is no point wasting money painting.
All ideas welcome!

I would imagine the first step to take is to discover why the walls are damp in the first place, is it only on outside walls? If so could be leaking guttering, soli pipes etc maybe try leaving the damp areas unpainted until it dries out complete, paint doesn't generally like wet areas. |

He's spot on the man  |

By damp I'm talking from the inside, general steam from kitchen/bathroom/utility, not leaks or damage to the exterior. The upvc windows aren't helping the ventilation issue I know but it's a work in progress. |

some of the paint has peeled off in my bedroom and it's not a damp problem it is condensation because i've had it checked out. it's just the damp peels off the paint, and it only comes off where there are corners
i painted it onto prepared plaster using normal paint. but in the bathroom i used bathroom paint and it hasn't peeled off, does have mould on it (showing there is condensation damp still).
where's it peeling off? |

Plastic Windows and solid walls are a crap combination. You need ventilation.
The best system would be a whole house one that extracts the heat from the air so you don't lose it outside. |

You'd have been better off rendering the walls!.
Old solid walls nearly always attract moisture from outside to inside. The fact that you've got modern sealed windows and doors won't help |

Most people unfortunately still belive in the myth that upvc windows "cure" condensation, when it actuality what they they do is transfer the condensation to the next coldest spot |

If its condensation can you get in the habbit of putting the windows on vent lock? I have one of my bedroom and kitchen windows on vent all the time. In winter i open them fully instead for 15 mins evey day.xx |

New windows and vent. system are on the to do list but with a 4 storey house it's probably going to require selling a kidney or two  |

It's happening on interior stud walls too, just small patches that absolutely won't hold paint for more than a few months before it falls off again  |

Condensation is caused by air temperature and humidity, there linked if your room is 22 degrees and has 50% humidity for every 1 degree loss in temperature humidity increases roughly by about 10% and vice versa.
Most of the humidity/condensation problems inside are caused by modern living, kettles, cooking, showering, dishwashers, clothes washing/drying, were constantly introducing vapour into the inside of the house, this is then trapped by modern house building methods, it will and has to condense at some point on something (coldest spot used to be windows).
There are some very nifity extractors that have air exchanges built into them that will remove damp air but retain the heat but even these have there limits where outside humidity in this country can remain high in winter anyhow.
Other than that it's really a dehumidifier. |

"I wouldn't use chalk paint on your walls "
Totally unsuitable for bathrooms or kitchens! There are several paints on the market which are specifically designed for such high humidity areas... |

i just use mould remover and keep things away from the walls when i can, and leave the windows open. it helped a fair bit. there is a lot of condensation from drying washing, showers and just having a house full of people. i'm not bothered about the paint coming off, it's only at the top of the walls and i'll leave them as they are. was worried it was a damp problem from outside but it got checked for that and it isn't so i'm not too fussed.
we had a flood 2014 so that didn't help either. |

From what I've read they are not really suitable for period houses though and just encourage mould. |
