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.
This wall has a texture on it that will look bad under the new wallpaper, and it will also interfere with adhesion. So the wall needs to be skim-coated / skim-floated to smooth it. But the current paint on the wall is glossy, as you can see on the right side of the photo. The smoothing compound is sticky stuff, but it (like many coatings) cannot be trusted to adhere to a shiny surface. I say it’s like the toy Colorforms … the new material will kinda stick – but not really stick . But if the surface is dull , or matt finish , the new coating will be able to grab ahold and adhere . To make this wall surface dull , I’m rolling on a primer that will dry with a flat / matt finish . There are various primers out there that will adhere to a glossy surface and then dry flat. But I’m using my trusty wallpaper primer , Roman Pro 977 Ultra Prime . Yes, this is a wallpaper primer . But it also checks all the boxes … it sticks to just about anything , it dries quickly, especially with a fan blowing on it, and it dries with a matt finish that wallpaper paste – and smoothing compound – will adhere to. At $70 or more per gallon , yes, this stuff is expensive . But it works , it’s low odor , it’s already on my truck , and it saves having to carry around an assortment of of primers and materials. Here’s my smoothing compound. Sheetrock brand Plus 3 joint compound used for working with drywall . Note that quick-dry formulas , nor spackling compound , are not suitable and won’t hold up under wallpaper . You can search here for my other posts to see more about the smoothing process for textured walls .
Wallpaper is to go on the top 2/3 of the walls in this large dining room. But the walls are textured, and that texture will show through the new paper. Which looks pretty bad , IMO , especially since most the design is plain white background. So here I am applying a skim-coat by skim-coating / skim-floating the wall to smooth over the texture.Close up. A lot of people use a wide broad knife or drywall taping tool . But I prefer the control I have using this trowel . There will be ridges and valleys and imperfections . But tomorrow, when the smoothing compound is dry , I will sand everything smooth . I have to say, I’m pretty darned good at smoothing walls . 🙂I like to use the Plus 3 Joint Compound by the Sheetrock brand. It’s much easier to sand than the standard joint compound . Do NOT use the ” quick set ” version – coatings such as primer , paint , or wallpaper don’t like to adhere to this stuff . It’s made for small patches , not covering entire walls. BTW, for short, we simply call this ” mud .”Once the walls have been sanded smooth , all the dust vacuumed up, and residual dust wiped off the walls with a damp sponge , then I will apply my favorite primer, Roman Pro 977 Ultra Prime , made specifically for use under wallpaper .
This wallpaper in a Houston Heights townhome’s breakfast area was hung by “the contractor’s guy ” and he ran into some problems. First, I suspect the wall had not been adequately coated with a primer designed for use under wallpaper . This may be a large part of why the paper has come loose from the wall in places, and shrunk and gaps at the seams. The wallpaper is an old-fashioned British pulp material , which is quite different from the non-woven material that this company usually prints on. If the installer was not familiar with hanging a pulp, yes, he can have a tough time of it. There are other issues that the homeowner is unhappy with, such as tears, slices, patches, and, of course, these un-stuck seams. I’ve posted more pics previously, if you can Search to find them. My task is to get the paper off and then prep the wall for hanging new material. Most of the paper pulled off the wall easily. But there were areas where the guy had used a stronger adhesive to try to hold the edges down. Those would not come off the wall without causing damage to the wall. So I pulled off the top, inked layer and left the paper backing on the wall. This stuff is porous and will bubble when coated with a water-borne primer , and with wallpaper wet with paste. So I sealed these areas – I sealed the entire wall, in fact – with Gardz (by Zinsser ). This stuff is pretty incredible. It’s a thin, watery primer / sealer that soaks into the surface and binds loose components together, then dries hard and solid . Latex paints and other water-based products (usually) won’t penetrate it, so won’t cause the underlying material to re-wet, expand , and bubble . Just a note … due to pandemic and other supply chain related shortages , Gardz has become difficult to find. This can was about 1/4 full and I had it sitting behind my trash can, intending for weeks to toss it out. Now I’m glad that I procrastinated! Once the Gardz sealer was dry, I skim-floated over it with joint compound , a.k.a. ” mud .” In most areas of the wall, my skim coat was as thin as possible, but I did have to make it much thicker over the areas with the paper backing stuck to the wall. I set up three fans , and also used my heat gun , to get the smoothing compound to dry. I like the Plus 3 version made by the Sheetrock company. It sands easily and doesn’t make too much air-borne dust. It took a couple of hours to dry. Then I sanded it smooth , vacuumed up the dust with my Shop Vac , used a damp sponge to get residual dust off the wall , and then let the wall dry once again.Finally I applied a coat of my favorite wallpaper primer, Pro 977 Ultra Prime by Roman. I used a paint roller to roll it on to the main areas, and an angled trim brush to cut in around the ceiling and moldings. Here is the wall all smoothed and primed . Originally I had planned to strip , prep , and hang this half-wall all in one day. But ended up the prep took more time than I anticipated (about 8 hours ) , so we’ll let the primer dry overnight and save the wallpaper installation for another day. The wallpaper pattern is called Strawberry Thief and is by the famous William Morris designer from the very early 1900’s . I’m sure seeing a surge in interest in his patterns, particularly this one. Do a Search to see other jobs I’ve done with it.
OK, so this master bathroom suffered a water leak, and the plumber had to cut through the drywall in the potty room in order to access the shower fixtures. Here the contractor has replaced the cut-out piece of Sheetrock. He did a really nice job. For the most part. Of course, he didn’t bother to remove the wallpaper before doing his repairs. This is vinyl paper (thick, slick, slippery, backing absorbs moisture) and really should have been removed first. But I was able to work around the patched-in area.The prep for this small room was a lot more involved than I anticipated, and required an extra day. Too complicated to get into, but there were two layers of wallpaper, and no primer by either of the previous installers. Original install dates back to the ’80’s. It took me a day and a half just to do the prep on this small commode room. The room finished. Note the stripes centered nicely on that back wall. The pattern and material were chosen to coordinate with the green stripes in the main area of the master bathroom. Kill point (final corner) over the door. I “shrank” some sections in order to get even widths and maintain the pattern repeat and match.The plumbing problem also damaged an area on this wall outside the water closet. So this area around the door needed to be replaced. The homeowners didn’t have any left over paper, so they chose something similar in color, style, and composition to the green striped paper you see to the right. Here is that transition door wall finished. We decided to use the stripe to define the ‘break’ between the two patterns. The alternative would have been placing the stripe against the door molding … but I felt that would be too repetitive, plus it would have left a cut-off section of flowers running along the side of the green stripe, and same on the opposite side of the door frame. And, yes, the wall definitely is not straight, square, or plumb. And here is that opposite side of the door frame, with the stripe running nicely along the shower tile. Some overlapping was involved in this job. Since the wallpaper is vinyl, and vinyl is slick, you need a special paste to be able to grab ahold of the glossy surface. These days, I sure don’t use often border paste, also sometimes called VOV or Vinyl Over Vinyl . But I was mighty glad to find this 10+ year old container deep in the bowels of my van. Still fresh and sticky, too!Besides borders not being popular today, these “satin” and “silk” look wallpapers are not very common. But this is exactly what the homeowners were looking for, to coordinate with the existing, 30-year-old paper in their master bath. Saved them having to replace all the wallpaper in both rooms! This paper is very economical, too. The couple shopped with Dorota at the Sherwin-Williams in the Rice Village, and she was able to track down the perfect material, pattern, and color. Now, aside from all the positive things I just said about this paper in this current application, I do want to make clear that I am not at all fond of this type material. Without getting into a long schpiel here, please click and read the page link to the right “Stay Away From Pre-Pasted Paper-Backed Solid Vinyl …. ” I will also add that I’ve developed a technique to work with these materials, and so far the installs, including today’s, have been going nicely. One double roll bolt had some of these blue mark printing defects running through about half of it. Luckily, most of these were on a section of paper that was cut off in order to turn a corner, so was discarded and not put on the wall. Exclusive Wallcoverings is the manufacturer. Usually I work with their non-woven or traditional paper products, which are quite nice. The home is in the West University area of Houston.
This is a typical wall texture provided by many builders of new tract homes in the suburbs of Houston. Wallpaper doesn’t look good hung over this texture, because the bumps will show through. And the high-and-low ridges and dips interfere with good adhesion to the wall. So this accent wall will need to be skim-floated to smooth it before the wallpaper can go up. In addition, this wall started out with a semi-gloss paint. I worry about my materials being able to stick to a glossy surface. So, before applying the smoothing compound, I am priming the wall with something that will stick to the gloss paint, as well as provide a matt finish for the smoothing compound to adhere to. I’ve discovered that my favorite wallpaper primer also works great for this purpose. It sticks to just about anything, and dries almost dead-flat. I like Roman Pro 977 Ultra Prime. I use a trowel (top) to spread on the smoothing compound. The 3″ stiff putty knife is used to knock off big-ish chunks on the wall, or bits of grit. I use the 1 1/2″ flexible putty knife to apply the smoothing compound in tight spots like around electrical outlets or between a door molding and a wall corner. The smoothing compound I use is drywall joint compound, and I like the Sheetrock brand Plus 3 version. Search hear (upper right) to see previous posts with photos of this material. Bottom of photo – trowel sticking to the wall shows you just how tacky this stuff is. Above that are blobs of the smoothing compound waiting to be spread around, and a little bit on the left initially smoothed onto the wall. At the top of the wall you see a section that I have already covered with the smoothing compound. This will dry overnight, and I will sand it smooth tomorrow. Sometimes I can float a wall, get it to dry, sand it smooth, prime, and hang the paper all in one day. But this texture is so heavy that more time is required for it to dry, so it will need an overnight sit. Some fans, plus the home’s heat and/or air conditioning help to pull moisture out of the smoothing compound and hasten dry time.
The powder room in this 1990’s home in the Houston Heights is being updated, and that means replacing the wall-to-wall vanity. Here the vanity has been ripped out. The areas where the backsplash was adhered to the wall have pulled the top surface of the drywall off. In addition, the plumber had to cut out a section of drywall in order to gain access to the pipes, so he can install the new faucet and handles. You can see the connections roughed in. You can’t hang wallpaper over this mess. First of all, it way too uneven – all those bumps will show under the new wallpaper. And the outline of the ” trapdoor ” will leave a big square ridge under the paper. Thankfully, the plumber secured the panel with drywall screws – most plumbers just leave you with a chunk of drywall floating in space, or even just an empty hole. Back to patching issues … in addition, the torn areas of drywall will absorb moisture from the wallpaper primer and / or paste and expand, creating bubbles that will show under the new paper. I needed to fill in dips and gouges, even out high areas, and prevent bubbling drywall. Gardz by Zinsser to the rescue! This is a penetrating sealer that soaks into porous surfaces and then dries hard, binding them together and creating a stable surface, as well as resisting moisture from water-based top coatings. This picture doesn’t look much different, but here the torn drywall is a little darker, indicating that the Gardz has soaked in and dried. The surface is now ready for a skim-coat. But first, the trap door needs to be addressed. I covered the cut areas with four strips of self-adhesive mesh drywall tape (no photo). Then I went over everything (wall to wall) with joint compound (commonly referred to as mud ) (no photo). Because of the thickness of the high and low areas, this had to be a thick coat of smoothing compound, and would take a long time to dry. So I went to the jobsite two days ahead of our install date, to do these initial repairs. And – no – you can’t use quick set or hot mud or 5 or 20 minute mud to do these repairs. These products are intended for repairs of small areas. Top coatings like primers, paint, and wallpaper paste do not stick well to them. Don’t let a contractor sweet-talk you into letting him use any of these to smooth a large area of wall.Here is the wall after my first, heavy, coat of smoothing compound. I use Sheetrock brand’s Plus 3.The bubbles you see just left of center show that Gardz didn’t 100% do its job of sealing out moisture, as a little expansion and blistering has occurred. Not a biggie. These will disappear when the surface is sanded. There is usually not a problem with these re-appearing.When I got to work two days later, the smoothing compound had dried. I sanded pretty smooth. Then vacuumed up the dust on the floor, and then used a damp sponge to wipe residual dust off the wall. This is important, because no coating will stick to dust. The wall still wasn’t perfectly smooth, so I did another skim-coat. This was much thinner, so didn’t need a lot of time to dry. I used a fan and my heat gun to speed things along. Once that was dry, I sanded it smooth, vacuumed and then wiped off all dust. Then rolled on my favorite wallpaper primer Roman Pro 977 Ultra Prime. I have the paint store (Murphy Brothers in central Houston) add a little blue tint, so I can see it when I apply it to the wall. What a transformation! Now this wall is ready for wallpaper!
This Brooklyn Toile wallpaper by Flavor Paper on an accent wall in a nursery went up beautifully. The contractor had added new Sheetrock to one wall, and painted the other, old/original wall. I skim-floated both walls and sanded smooth, primed, and hung the wallpaper. Perfect! (Search here to see my original post.) But within less than a month, the homeowner contacted me and said that the wallpaper was ” coming off the wall .” It was a 1920’s bungalow in the Woodland Heights neighborhood of Houston. And therein lies the brunt of the problem. The wallpaper itself is not ” coming off the wall .” What’s happening is that the wall surface itself is coming apart – or, delaminating . This is because multiple layers of paint and other substances on the wall may not be compatible. A probably scenario: In 1920 oil-based paint was used. Later someone rolled on a coat of latex paint. Then the homeowners redecorated and used gloss paint. Then some ” flippers ” who had watched too much HGTV slapped on more paint without bothering to de-gloss or prime first. And somewhere in the mix you’ve got cheap paint and dust and other incompatible materials.Over time, and especially when stress is put on the wall surface, such as when wet wallpaper paste dries and the paper shrinks, this stress can tug at the wall and actually pull these layers apart. There are other contributing factors, too, such as humidity, temperature, and location. I find it interesting that the worst parts of the affected seams were toward the top of the wall. This speaks of heat, humidity, and forced air (either hot or cold) coming out of the air vent just to the right of this wall. This photo is of the area over a door, very close to the air vent. See how thick that is? It’s not just the wallpaper. There are several layers of wall coming apart. Some layers are clinging to the back of the wallpaper, and some are staying stuck to the wall. Multiple layers, many years of coatings on this wall. Easy to see the many layers. The paper itself, my blue primer, my layer of smoothing compound, paint, more paint coming off the wall. Then multiple layers of paint and texture still clinging to the wall. This shot is just below the ceiling.Same thing happening at the baseboard at the floor. Layers of paint separating from the wall in chunks. Some pulled off easily, and some I had to chop off with my 3″ putty knife.Most of the paint and unstable surface material clung to the back of the wallpaper. This pile is just three strips – only half the wall. But it’s thick and stiff and heavy because of the paint stuck to the back of the wallpaper. There was so much and it was so heavy and bulky that I had to carry it out to my van in two trips. When I got home, it totally filled my trash bin. Here’s the wall once all the other layers came off. Brushing my hand over it revealed a layer of dust. No wonder the paint and other coatings wouldn’t stick. Nothing sticks to dust. It’s like flouring a cake pan… The paint or wallpaper will kinda stick – but won’t really stick. Paint on top may be fine. But add a little stress from drying / shrinking wallpaper, and you may end up with layers that pull apart. Wiping the walls with a damp sponge removed a lot more dust. But the wall still felt chalky. Whatever type of paint this was, it was not holding together. I had to stabilize this chalky surface. Enter Gardz, a wonderful product – Gardz is a thin, penetrating sealer that soaks into porous surfaces and binds substances together. It dries hard and creates an intact surface. The darker area in the picture is where I’ve rolled on a test area. Gardz is thin like water, and it runs and drips and splatters. It’s imperative that you cover floors, countertops, and baseboards, and roll carefully, and roll upward rather than downward, to minimize runs and drips. A microfiber roller holds the liquid well, and reduces drips. Gardz is made by Zinsser. No photo of the finished wall, but I was very pleased with the stability of the surface. No more chalk or dust. Now, there still could be unstable or incompatible layers deeper inside the wall. (Latex paint over oil without proper prep.) But for now I feel pretty confident that this wall is solid and will hold up to the next process in preparation for getting the new wallpaper up.
Always save the leftovers from your wallpaper install! I hung this textured vinyl faux silk ” Wild Silk ” wallpaper by Thibaut ( # 839 T 344 ) at the beginning of the pandemic, a year and a half ago (April 2020 to see my blog post). Since then, the house had significant shifting of the foundation, which caused damage to the drywall over doorways. Here the homeowners’ ” guy ” has very skillfully cut into the Sheetrock, replaced studs inside the wall, and closed up the hole, leaving everything amazingly smooth, with no damage to the surrounding wallpaper. I don’t think I’ve ever seen a contractor do work this well.I didn’t get pictures of my “during.” But here is the area right after I used left over scraps to replace the missing piece. I used a double cut / splice to to meld the two strips together at the bottom. (sorry, no pic). It was tricky getting the replacement strip of wallpaper in there, because the new strip expanded and twisted differently from the original wallpaper. Too difficult to explain here, but the bottom line is that the new strip was too wide for the space, plus the pattern drifted and so would not line up on the left side of the new strip. All this is evidence, I believe, that, with time and weather, the wall continues to shift and stretch. I did a lot of tweaking and twimming and touching up with pastel. All said and done, it turned out great. The white line you’re seeing is fishing line hung from the ceiling – not the wallpaper. 🙂 Still, there was a bit of a white line at the edge of the original strip on the right side. (not pictured) This was caused by the contractor either abrading from overworking or from smoothing compound infiltrating into the edge of the wallpaper. Either way, it was extremely minor, and unavoidable. Still, it left a pretty noticeable white line along 18″ of seam area. In the photo above, I have used chalk pastels to color the edges and even out color differences. From three feet away, you can hardly see it! Here are the artist’s pastels I used to disguise the white area. They’re from Texas Art Supply (right around the corner from me!) I also used these chalks successfully on a 2″ circle of wall where someone had either abraded the surface by rubbing, or possibly bleached the area. No pic of that, but I was very pleased with how it turned out.
