This home in the Meyerland neighborhood of Houston was flooded during Hurricane Harvey, and has been redone, and is now ready for final touches, like decorating, i.e. – wallpaper!
The first three photos show how the contractor left the walls. It’s hard to conceive how anyone could think these walls are “ready for wallpaper.”
What you are looking at is where the contractor ripped off the top, inked layer of the original wallpaper. Most of them don’t realize that there is a backing layer of paper that is left on the wall, that should be removed, too. Simply soaking this with a wet sponge will reactivate the paste and allow the paper to be removed easily, and with no damage to the wall (esp. if there is a good primer underneath the paper). Read my page to the right “How to Strip Wallpaper” to see how this should be done.
Instead, this contractor left the paper backing on the wall. Some of this porous backing is exposed. Other areas have been covered with the paint that was used on the woodwork. This solvent-based paint “raises the grain” of the surface it’s applied to – see all the hairy fibers from the wallpaper backing that have gotten stuck in the paint and raised up? Some of them are more than 1/4″ high. They create a gritty feeling on the surface, like really coarse sandpaper.
The surface is uneven, and the bumps will show under the new paper. The unevenness also means that areas of the paper will not be able to contact the wall, so there will be gaps and air bubbles and poor adhesion. The backing of the original wallpaper has been exposed, and when new, wet, pasted wallpaper gets placed on top of that thirsty paper backing, it will absorb moisture, expand, and bubble.
I had three missions. 1.) Seal the surface 2.) Smooth the surface 3.) Prime with a wallpaper-appropriate primer.
I rolled on a coat of the penetrating sealer Gardz to seal the surface, so that my following treatments would not cause the paper backing to bubble. When that was dry, I skim-floated the wall with a coat of joint compound. In the areas where the hairs were 1/4″ high, the skim coat was pretty thick, and took a good while to dry. Once that was dry, I sanded it smooth, then vacuumed the dust of off the floor, used a damp sponge to wipe residual dust off the walls, and then followed up with another coat of Gardz. It will soak into the joint compound and dry hard, forming a stable surface for the new paper to adhere to.
The last photo shows the wall once I finished.

Yes! If people here in the States were lucky enough to find dual-skilled workers, they could hire one craftsman and have one-stop shopping, along with excellent work. 🙂
