rendering

brooks · Jan 12, 2007 8:40 pm

I have a cottage with a kitchen in a sixties extension. On an outside wall there is mold up to about a foot from the floor and about 3 - 4 feet across. I have found that the other side of the wall in a neighbours property is rendered and at the same height the render is broken leaving large gaps. I assume rainwater is getting in and being soaked up by the brickwork and ultimately causing the mold, probably helped by the kitchen environment. I am arranging to have the render repaired. Would it be reasonable to treat the inside and repaint and leave it to dry out or would it be better to replace the affected plaster which is in good condition?

Thanks

If the plaster has had constant damp/water its probably had it. I'd replace it once the source of the problem is fixed. Are you sure the mould isn't from 'rising damp'?

I don't think it's rising damp. The render on the other side of the wall has broken away at exactly the same place as mold is appearing on the inside and there is no problem either side. Anyway, hanks for your reply. I'll probably have the plaster replaced.

Fix the outside and leave it to dry thoroughly before painting inside.

Otherwise, if there any moisture is left in the wall it will try to go through the paint work and you can ad up with pilling wall.

Rising or falling damp...IMHO
