Hi guys,
I'm chewing on life's gristle at the moment. Whoever painted the pebble-das hed wall I'm preparing didn't prime it properly, so the existing paint has adhered poorly and is grudgingly and patchily flaking off as I attack it wi th a wire brush, knocking off poorly embedded pebbles in the process as wel l. Whoever thought up pebble-dashing and especially the concept of over-pai nting it should be shot, I reckon. Anyway, after the old paint has been removed, the render & shingle undernea th are exposed and the surface is dry and powdery. It therefore needs primi ng. Am I alright to just use PVA 5:1 with water for this purpose, or do I r eally need to splash out on Sandtex's fancy and expensive stabilising solut ion? Advice and/or moral support from a fellow sufferer at this trying time would be nice.
Cheers.
