Render Systems said:kirk johnstone said:ironmonkey said:evening all,quick question about top coat render.I laid up first coat before christmas and the the weather came in,i am going to second coat this week,my question is whether to damp down or uni-bond first coat to control suction.What do you think?
do both mate, give it a good soak down then pva it. did you use waterproofer in the first coat?
Hmmm well now... young chap you shouldnt need to do anything to the scratch coat in this weather as it will be damp anyway. also you never put pva onto exterior render the suction should have been controled with a waterproofer in the scratch coat... also your method seems a bit ridiculous as if you did pva it and then watered it on to it would be like a bloody waterfall running down the wall old bean...
