Kids did some felt tip pen handiwork on a wall I was about to paper. I didnt think this would be a problem and painted over the drawings with some Polycell Base Coat to block it out. I papered a few days later. Within 24hours the wall was a disaster. Huge gaps had opened at the edges and bubbles had formed in all the areas where the drawings had been blocked out. I have tried to stick the paper again and again (solvite) but it simply lifts up as soon as the paper dries.
The paper elsewhere on the same wall is sound. Its just where the pen and basecoat are.
Obviously I shall have to strip the wall and start again, but what can I do to the wall to prevent it happening again. Its like its not absorbing the paste where the base coat is.
