Whoops! Previous Installer Hung Wallpaper Over Wallpaper

Previous installer broke just about all the rules, but the paper has held up wonderfully for nearly 25 years.

I’m going to hang new wallpaper in this hall bathroom, and first must remove the existing paper. But – surprise! When I removed the outlet cover, I discovered that the previous guy hung this floral paper on top of the original paper. Ouch!

Here’s a better view. You can clearly see that other paper underneath there.

An interesting side note … the original paper looks a whole lot like the pattern I had in my powder room for many years. I loved it.

Anyway, both these papers are solid vinyl material, which is, essentially, plastic , and has a slick surface. Wallpaper paste won’t adhere well to this shiny surface. Even without taking the time to strip off the original paper, a primer should have been applied over that vinyl. Yet, as you see, this paper has hung on well for two decades.

He used regular paste, too – not something formulated to stick to a slick surface (which we call VOV or vinyl over vinyl ). Again – amazing that it stuck. And very glad that he didn’t use VOV – be cause that stuff is near impossible to get off!

Another problem with hanging wallpaper over old paper is that the seams of the bottom paper will show through the new paper.

1990’s paperhanger didn’t prime the wall , either.

To remove this wallpaper, I stripped off the top vinyl layer of both layers of wallpaper. That left the paper backing of the original wallpaper still adhered to the wall. Here I’ve soaked that backing with water , using a sponge and bucket of warm water, applied over and over again, until it soaked in and reactivated the paste. 30 year old paste!

Here I am gently scraping it off the drywall . As you can see, no primer was applied to the drywall. Gee, folks! A primer formulated for use under wallpaper should always be applied, to any surface, before hanging new paper. I like Roman Pro 977 Ultra Prime . Besides providing an appropriate surface for the wallpaper paste to bite into , easing installation by allowing slip , and withstanding the tension caused when wallpaper paste dries and the paper shrinks and tugs at the wall (which could cause seams to come loose ), a primer will seal the drywall and ease removal of the wallpaper when you redecorate down the road.

Without a primer, it’s common for wallpapers to “bond” to uncoated drywall , which makes removal nearly impossible. Like I said, I got really lucky with this one, because the original paper did come off relatively easily and with no damage to the wall surface .

The home is in Houston .
