Hi there I have to plaster over some semi shiny paint with little to no suction.after reading some reviews I've seen bonding agent which I will try but do u need to pva after bonding agent has dried,will then skim with thistle multifinish,thanks
 
No, but read the instructions carefully on the agent some not suitable for no suction surfaces.. Boom boom
 
If its only a small area then Wicks bonding agent is ideal as its packaged in a small tub. Anything larger a tub a bond it will be your best bet.
 
Will sanding the walls have the same effect I.e take the shine away from the paint or is it not worth the risk,as it's a hole room.thanks
 
i would pva the walls, the bond it types need to be applied the day before.
the pva needs to be mixed just right, not to wet, not to strong, open the windows, leave for a while while you get the rest of your gear set up. if it is still to wet put a sponge over the walls, then skim.
