Paint cracking and peeling off interior walls

The house is 400 yrs old with very thick stone walls. Some walls have been covered in plaster and painted, and in some areas this paint has cracked and is peeling. The house is very exposed and in the last few years there has been much flooding in the area, though the house did not flood. The cracking and peeling has mainly occurred around a bathroom window and above radiators. There is also some black staining appearing in corners of outside walls. We are hoping to decorated and will need something that breathes and is hardwearing. We appreciate any suggestions you may have.

    Good Morning

    From what you have explained above its sounds like you have built up moisture within the walls, this is leading to an increase of hydraulic pressure and forcing the paint from the walls.

    For a breathable and hard wearing paint we would recommend the Beeck Internal Mineral Paint range and in particular either the Beeck Maxil or Beeck Sensil, these have excellent vapour permeability and scrub resistances.

    It is worth noting that paint alone may not address the issues, as the paint is only as good as the surface that it is applied too. If you have a render/plaster that is not breathable you will still likely have issues here, as the moisture will be unable to fully escape.

    If you wanted to discuss this in more detail and run through the suitable products in more detail please give me a call on 01208 79779.

    Good Afternoon,

    We own a property with solid 800mm thick stone walls in Devon which are predominantly limestone, the majority of the property has been rendered externally and plastered internally with a range of plaster types and seem to take any paint without any trouble but in one area of the property which has no external render and no interior plaster the paint begins to discolour over a number of months.

    We have tried wire brushing old paint off in case there was a reaction there before painting with 'breathable paints' but this doesn't seem to make any difference. The walls appear dry and doesn't seem to suffer from condensation so we are not sure if there could be another reactions taking place, would any of your paints be more suitable? the 'breathable paint' we have been using was only recommended by a local builders merchant and not a specialist lime paint or similar.

    Any advice would be welcome?

    Kind regards,

      Hi Michael

      It is very difficult to say without seeing the wall and the discoloration.

      Does it only discolour? or is there any growth or damage to the surface finish (flaking, cracking, blowing etc.)?

      Would you be able to send me any pictures of the effected areas?

      Kind Regards
