Alright lads, been lurking for some time. So here goes..
Been asked to s & c an external gable end wall on a detached terrace - it's the only one in the street that's detached. The chimney breast on the downstairs internal wall is showing signs of damp - high up in the corner of the wall near the chimney there's salts coming through, there's another patch on the chimney breast and I've noticed a patch by the bay window on another wall. They don't reckon the damp is rising so they're considering having it rendered to stop the damp. The external wall (see pics below) seems to have been painted with bitumen some time ago and then painted over. Question is, will the render stop the damp (scratch coat with water proofer) and can you render over the bitumen and the paint or do you need to hack it off? Could I just SBR it then throw a scratch coat on?
