I have a ground floor hallway that extends up a stairwell to a landing and then to the upper floor hallway - a large space - previously wallpapered in vinyl. The surface is sound but the paper is dark and I need to freshen it up.
Due to access problems in the stairwell and time/health limitations I cannot strip the paper and then paint - I am aware this is the best solution but it is not a viable option for me at the moment.
I therefore would like to paint on top of the vinyl wallpaper. Planning to use one or two coats of emulsion.
Any advice on how to approach this? Should I treat the paper first (diluted bonder) or key the surface by lightly sanding? Or is it a total non-starter because it is vinyl?
Thanks for any advice
