Sheetrock Repair After Removing Wallpaper


I’m trying to find a suitable fix for sheetrock that has been damaged by aggressive wallpaper removal. I’ve encountered this problem several times lately due to changing trends and homeowners wanting to save money by doing their own wallpaper removal. In several places, a layer of two of the sheetrock paper has been taken off. The sizes of such damaged areas vary from a few square inches to a couple square feet. Within a few minutes of skimming such areas with mud, the paper absorbs moisture and blisters or bubbles. I’ve also tried a sealer on them first only to have it blister the same way. I’ve had some success on small areas by smearing wood glue on the damaged portions and allowing to dry before mudding. Anyone know of a great tip for tackling such an issue on the larger areas?

  1. I have always primed damaged areas with an oil base primer, Kilz or Cover Stain, allow to dry for a few hours then do the mudding. This works fairly well with little or no bubbling. One thing; make sure to saturate the paper and especially any open (exposed) sheetrock. Plus give it time to fully dry, coat it too soon and there will be bubbles.

    What sealers have you tried? Water based primers will always cause some bubbling. I also use setting mud, typically 45 minute but do use 20 minute for small patches. I think the setting mud (powdered) works better than all-purpose.
