Plastering

What to do about repeat plaster blowing in an old house?

Every 3 years or so, the plaster blows near the bottom of the wall. It is an old house with no foundations and slate floors.
Is it possible to use something that will withstand the dampness, to stop it recurring?

Knock all the loose plaster off the walls about a 1.000mm up inject with dry zone you can get this from Travis Perkins when walls have dried out plaster with gyproc hard wall backing coat then use renovating plaster to finish. Job done

Hi if the house has no foundations then this would suggest it is an old house, it would seem that the wrong materials are being used or have been in the past. I would look at the substrate of the building and use the correct materials on it to rectify the problem and do not inject with a damp course treatment but use a traditional Lime plaster which would deal with your damp problem.
