Old Wallpaper Could Not Be Stripped Off

The homeowner is ready for a new look, so the red wallpaper with the “broken coral” pattern has to go. I am pretty darned good at removing wallpaper, but this stuff was not agreeable with the idea.

Normally, you peel off the top, inked layer, and then soak the remaining backing layer with water until the paste loosens, and then you can either lift the paper from the wall, or gently scrape it off.

But this top inked layer came off in tiny pieces – 1/2″ square. Which meant it would take a year and a day to get the whole room stripped off. Then, on my test area, when I tried soaking the paper backing to loosen the paste, it would have non of it.

The backing would not come away from the wall. And in the tiny 1/2″ square area where I finally did get the paper off the wall, there were more problems underneath. Meaning, a gummy, rubbery substance that would not come off the wall, and that left a residue behind that was unsuitable for hanging new wallpaper on top of – it would have necessitated a whole lot of additional skim-floating, sanding, sealing, priming, etc.

I believe that the previous installer either primed the walls with RX-35, or hung the paper with VOV ( Vinyl Over Vinyl), both of which are inappropriate for this type of paper, and both of which are nearly impossible to remove, and both of which leave the gummy, rubbery residue that is so difficult to negate.

I found it preferable to leave the existing paper on the wall. I removed any loose areas (virtually none), and then skim-floated over the seams with joint compound, to remove any vertical lines that could show under the new paper. That’s the white stuff you see in the 2nd photo.

When dry, I sanded that smooth, wiped off the residual dust with a damp sponge, and then primed with Gardz, a penetrating sealing primer. This will yield a smooth, stable surface for the new wallpaper to grab onto.
