Re: Wallpaper Residue Painted Over
Too many variables to suggest the proper course of action, though my colleague does highlight one good method.
If there is no texture on the wall, then simply sanding and priming will do. If it's textured, then sanding may not work very well, particularly if there's much glue residue that needs to be addressed.
Assuming the worst, the walls should be scrapped to remove any excessively high spots, then floated with drywall topping compound, retextured, primed, and painted. A lot of work, yes, but the results will be pristine walls.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
