Thinking forward to a job I have coming up I thought I would ask if any one has a good working solution for the following.
I have a large property to give a full redec to its built in the 90s. The client wants to remove dado rail which has wallpaper underneath, make good, and finish in emulsion. Now my usual approach to painting previously wallpapered walls is to line them. My reasoning is that no matter how well one washes off the paste from the wall, there is a residue impregnated into the plaster. Painting over with emulsion could result in crazing.
So any suggestions for a good sealer/ primer that would fix the paste residue and take emulsion finish?
Of course I may have an issue with different textures showing through as above the dado is in emulsion and the paper is on bare plaster.
I am looking for an alternative to lining the walls cos they are in good order. And lining the walls will add considerable cost to the project for my client.
