Hi everyone So, BT have been and dug up the road so bits of my house fell off prompting me to look at the ground-level rendering. Take a look
What I seem to have is multiple layers of paint over a crumbling (in parts) render. It may not be the original render though, it could be occasional repairs over the years, as the rendering higher up seems OK, mostly. Anyway, the plan is to hack away any loose bits, PVA it to prime it, then mix up a 1:6 cement:sand+plasticiser, and trowel that on, then overpaint with a gloss black exterior paint. Anyone got any better ideas? Cheers J
