additive

[jb20406]

got a bit of internal rendering to do in me utility room after ive damp proofed it, can anyone recommend a good, cheap waterproofing additive, the walls are piss wet at the moment, protimeter nearlly blew up when i tested it but hopefully the ultracure will sort that. i know the words "good" and "cheap" dont usually go together but you never know.

if u got wet walls paint waterproof membrane on and attach 2x2 or 2x1 pressure treated timber battons and board it if u dont wanna render it

You probably want to use SBR

There is some good info on it on the uk spreads website.
