Hello plasterers, I have done a fair bit of skimming but don't have much experience of base coats/rendering.
I am going to be skimming a wall this weekend but I think it will need a bit of levelling in places to make it good. The base is a mixture of painted plaster, render and filler that has been painted with a damp proof paint. It will be coated with Wickes plaster bonding agent to give it a good key before I start.
If I use bonding coat as a base coat to build up the low areas (up to about 6-7mm in places) how soon can I skim onto it? Or can I make up this depth with skim coat? I want to get it done in a day if I can. Also, what is the best plaster to skim with, multi or board finish, I have read mixed views on multi and also that you can use board on any low suction background?
Many thanks
