Hi all i have a 1940 property which has been rendered, we found damp in the bedroom when moving a wardrobe which looks to be coming from the corner of the window i have done a temporary repair with new mortar mix. but looking at the rendering it looks like it needs some attention, in a few places the stones have fallen off. im a bit unsure what to do for the best can you pebble dash over the top of the existing render? as it looks sound. or would painting solve my problem?
many thanks
