How to even out suction on mixed backgrounds . Doing a bungalow with grey plaster and shiny paint on most walls .grey plaster very porous paint not at all. How would you deal with it . PVa isn’t doing the trick. Blue grit and similar products don’t kill suction. Any suggestions?
Hi all . Got a bungalow to skim 1960. Walls are grey plaster and shiny paint so background has mixed suction. How would you prep for suction control and key. Blue grit and similar backgrounds don’t control suction. Any ideas
