Hi, I need some help with a pointing/render job. I have a external walls that at the corner have a crack about 15mm in width at the widest point it goes right through the wall. The problem was drains and has been resolved, although i still expect some more movement. The damp has caused some of the render to blow and needs repairing. I have basic pointing and render skills but what has thrown me is reading a quote from the insurance firm which where originally going to do the job. It states supply and fit expamet mesh and render including applying pva bonding. Is this correct or over engineered? My plan was to cut back, rake out, point leaving shy to then render. Is the mesh required being as it is a corner? Never used pva in render mix, will this help flexibility? and if so do i scrap the waterproofer? And one last question, where the damp has penetrated some of the render near to ground level it has become loose (not blown) and pitted what can be done to make this look better? it's not really deep enough to get a render finish. Many thanks in advance. DAN
