Hello, I am decorating our office and when taking the wallpaper off we discovered the wall is in really bad condition. A large amount of cracks in the wall along with big chunks of plaster and concrete have fallen off.
I just want to confirm I am doing the right thing here. I am going to coat the wall in PVA 50\50 with some sand mixed in too.
Then once fully dry the next day im going to apply PVA 1\5 to the wall and wait for it to go tacky.
Once tacky, I will apply a coat of bonding plaster to the entire wall, just like plastering.
Then when this coat starts to firm up I will apply finish plaster on top, and then a second coat once the first coat has firmed up.
Does this sound right? Am I using the right thing (bonding coat)?
