Considering that this previous installer broke just about all the rules of hanging wallpaper , his job looks good, seams are tight , and it’s held up for 20 years . This is one of the typical materials we were hanging back then, a pre-pasted , paper-backed , solid-vinyl wallcovering . Not my favorite material at all (often curling at seams , especially in bathrooms and/or when installed without proper wall prep ). Thankfully, they’re not very prevalent today, outside of the lower-end market. Anyway, these are usually fairly easy to strip off the wall . All you need is water , a putty knife , and patience .But here’s a wrench in the works – the previous installer hung this vinyl paper over existing wallpaper . A big no-no! You can see the original stuff peeking out around the light switch. That original wallpaper was installed by the builder in the ‘90’s , and almost always you can bet it’s been hung directly on un-primed / un-sealed Sheetrock . This can be very difficult to get off, without tearing up the surface of the drywall. If that original paper is paper instead of vinyl ( plastic ), sometimes it’s OK to leave it on the wall , prep it correctly, and hang the new wallpaper over it. So that was my original plan. Strip off the vinyl and its paper backing, and then prep the bottom layer and hang new paper over it. But, as you can see if you look closely at the edges of the bottom wallpaper, that fuzzy manilla paper backing is telling us that it, too, is a solid vinyl material. No matter how you might prep it, we don’t want this thick , slick , plastic stuff under our new wallpaper.Back to the topic of stripping wallpaper . Done properly , it’s not a horror show. All you need is water and patience . The theory is to reactivate the old paste with water , and it will let go and the paper will come off the wall. But water won’t penetrate the vinyl / plastic layer (and it won’t penetrate the thin acrylic coating on other types of wallpaper, either ). So, the first thing you need to do is remove that top layer. These solid vinyl materials are pretty cooperative. Simply get under the vinyl with a 3” stiff putty knife and then use your hands to pull it away from its paper backing . It usually separates and comes off in fairly large pieces. The same process works for thinner paper wallpapers , too, but it helps a lot if you sponge the surface first with water , as this seems to strengthen the fibers somehow, and you’ll get that top layer off in larger chunks (instead of 1” bits). Sometimes works better pulling from bottom to top, or from right to left…. experiment and see what works best.Next use a sponge and a bucket of warm water …… to wet that paper backing . You’ll want to go over each area several times , to be sure it’s thoroughly saturated . The idea is to get it wet enough that it will reactivate the wallpaper paste underneath . Be sure to cover and protect your floor and vanity countertop .Once that paste has softened , you should be able to use your 3” stiff putty knife to gently scrape the paper backing off the underlying surface . If you’re really lucky , it will release easily and cleanly and all you’ll have to do is pull with your hands.Here you can see the original layer of wallpaper underneath. Since this turned out to be another paper-backed solid vinyl material, it also had to be removed , following the same process outlined above. Once that top decorative vinyl layer was removed , the paper backing was left stuck to the wall. I wetted it , let it soak until the paste was soft, and then gently scraped it off the wall. Doing so revealed that – what did I tell you?! – yes, the builder’s wallpaper hanger didn’t prime or seal the wall before hanging the paper. This is usually disasterous, because the wallpaper will often actually bond with the drywall surface and be nearly impossible to get off. So I was really surprised that I was able to scrape this off with absolute no damage to the drywall . No peeling surface , no gouges , not even much paste residue (I did sponge off what I could). Once all that water evaporated and the Sheetrock dried , I did some minor prep touch-ups , sanded lightly , and then applied my wallpaper primer . I like Roman Pro 977 Ultra Prime .
The existing wallpaper in this sink / vanity room of a hall bathroom is unique, because instead of coming in rolls, it came in pieces of torn paper, each about the size of a paper plate, that were placed on the wall in random ways, with the pieces overlapping each other. This was a fairly popular wallpaper option back in the ‘90’s. I’m to hang new wallpaper in this room, so my first step was to remove the torn paper. This started out seeming easy, because the paper was literally falling away from the wall – but only around the top, and only the top 5” or so. The lower areas were stuck nice and tight to the wall. What’s going on?The original installer hung his wallpaper directly on new drywall / Sheetrock , with no primer and no other prep. Turns out that, under this wallpaper, there are actually several different types of wall surfaces related to the new drywall. The main part of drywall is grey in color . But here you see a band of white running along the top of the wall, under the ceiling, about 5” wide. This is where the joint compound was applied , to smooth over joints , drywall tape , and nail heads . But the curious thing is that the wallpaper is adhering to the drywall – but not to this white band of joint compound below the ceiling line. The reason? After the drywall guys sanded this area smooth, no one wiped off the dust left over from sanding . Thus, there was a layer of dust on the wall, between the wall and the wallpaper. Well, the wallpaper paste wants to bite into a solid surface, and it can’t get a grip on dust. That’s why you see this top portion pulling away from the wall. I have a lot more prep to do in this room. But before moving forward, I took a sponge and bucket of water and wiped the dust off that top portion of wall. Now I’m assured that any smoothing compound or primer or wallcovering or other that is applied, will stick . For reference, here’s a shot of the un-primed drywall being uncovered as I strip off wallpaper in another area. This picture shows the sections of drywall , joint compound , and also paint (from overspraying the woodwork ). Wallpaper adheres to all these different surfaces in different ways. Another reason to always use a wallpaper primer – it will adhere to just about any surface, and will create a uniform coating for the wallpaper to adhere to. I like Roman Pro 977 Ultra Prime.
