Rectifying a Mistake

July 2, 2021
Whoops! This wallpaper strip ended up too short. I suspect I forgot to add the 3″ extra for trimming at ceiling and floor. Sure would like to avoid replacing this whole strip.
I could have spliced a piece in horizontally. But that would have left a (slightly) visible horizontal seam, as well as put stress on the wall if the razor blade scored the surface. So I opted to patch in a piece. To disguise the patch, I cut along the design, and discarded the bottom piece.
Then I used scrap paper and cut along the same part of the design, making sure to leave a thin part of the design that would be overlapped (don’t want any gaps showing).
This patch was placed under the piece on the wall, with the top piece overlapping from above (less noticeable when viewed from above … the direction of lighting also affects this). Once all pieces were smoothed into place, it’s intact and homogeneous, and, best of all – undetectable.

Going For More Of The Same

February 9, 2021

I hung the original wallpaper in 2014, when the house was first built. The PEX water lines used in the home (flexible hoses instead of PVC pipes) were new at the time. Tragically, after a few years, the lines used in this home failed and caused leaks all over the house. Replacing all the water lines required cutting holes in MANY places throughout the home.

You can see in the photos where the plumbers cut out drywall and then patched it back in. This company actually did a good job of removing the wallpaper in the areas of their repairs.

Unfortunately, with the amount of wallpaper that was left over from 2014, I was not able to do repairs. The entire room had to be repapered.

The homeowner loved the pattern and wanted to keep it. It was still available, so she bought enough to repaper the room.

For various reasons, the original wallpaper was much more difficult to get off the wall than I expected. I could have gotten it off – but it would have taken about two full days.

So I opted to hang over it. It’s important to skim-float over the seam areas. First, because the seams will leave a little ridge that will telegraph through and show under the new paper. But also, because as wallpaper dries, it shrinks and puts tension on the seams. There is always the potential that this tension will cause the the surface below to pull away from the wall, and especially so if there is a weak area such as a seam. So you always want to avoid putting a seam on top of a seam.

So I skim-floated (do a Search here to learn more) over the seams, as well as over the patched areas left by the plumbers. See photos. Then I sealed the walls with Gardz, a product that penetrates and seals porous materials – like drywall joint compound and like this traditional British pulp wallpaper. Because it soaks in and dries hard, it helps to prevent moisture from paint or wallpaper paste from soaking through, and thus prevents bubbling of the underlying surface. That’s why this product is primarily used for sealing torn layers of drywall.

Although a bit glossy for my liking, Gardz is also a good primer to hang wallpaper on.

Interestingly, the expansion rate of the new wallpaper was a bit less than the original, and so the seams fell about 1/4″ to the right of the original seams. This reduced the worry of seams falling on top of seams and causing lifting.

It was a complicated room, and the paper was thick and stiff and difficult to work with. Prep took one day, and it took me two additional days to hang the paper (16 single rolls – 8 double roll bolts).

The wallpaper is in the line of Nina Campbell, by Osborne & Little, a British company. While most British papers these days are printed on an agreeable non-woven substrate, this one is a traditional, old-school British pulp … thick, stiff, difficult to fit into turns and angles, easy to tear, easily stained, non-malleable, plus the factory’s trimming roller blades must have been dull or wobbly, because the edges were not cut perfectly straight, which meant the seams had some “gaps and overlaps.”

Still, the finished room did look pretty darned good – even if it looks exactly the same as it did in 2014.

But that’s exactly what the homeowner wanted. So all is good and mission accomplished!

Fixing Weird Things That Happen To Wallpaper

December 6, 2020

The top photo shows a stain on the wallpaper that is probably related to a rain or hurricane event a few years ago.

Water stains (and also other substances, like rust, blood, ink, oil, tobacco, tar, cosmetics, and more) will bleed through wallpaper. So, before patching the area, it is imperative to use a stain blocker to seal the problem. My favorite is KILZ Original oil-based.

KILZ will seal off the stain all right. But wallpaper won’t stick to it. So, in the third photo, you see where I have primed over the KILZ with a wallpaper primer (tinted light blue, for visibility). It’s not necessary to prime the entire wall area to be patched, because this type of wallpaper will stick to itself with just plain old adhesive.

The striped pattern made for an easy repair. I took a straightedge and sharp razor blade and trimmed along the striped design, creating a long skinny patch. See fourth photo. You can also see the strip pasted and booked (folded pasted-side-to-pasted-side).

Once that sat and relaxed for a few minutes, I took it to the wall and appliquéd it over the damaged area, going the full height.

There was a very slight color difference between the paper that had been on the wall for 20 years and the paper that had been in a dark closet. Had I placed the white area of the patch next to the white area on the existing paper on the wall, the color difference would have been noticeable. But trimming along the blue stripe gave the eye a logical stopping point, and so the color difference is not detectable.

In the finished photo, you would never guess there had been anything amiss with this wall.

I used this same technique to patch over the bug-bite holes in yesterday’s post.

And another good reminder that it’s always best to order a little extra wallpaper, in case of the need for repairs later. Store the paper in a climate-controlled space … not the garage or attic.

The wallpaper is by Schumacher, and appeared to be an old-school pulp paper material.

Dog Tear Repair

February 5, 2020


Textured wallcoverings are tempting to dogs and cats, and this couple’s King Charles spaniel puppy had some fun with a couple of areas of their kitchen wallpaper. It is an embossed vinyl on a paper backing, made to mimic a woven grasscloth.

An applique a half inch higher than the tear, and the full width of the wall, was the least noticeable way to repair this. The thickness of the material made it more difficult to disguise the patch, but the finished job looked very good.

The third photo shows “border paste” – also called vinyl over vinyl (VOV) – which was called for in this instance. Vinyl wallcovering is somewhat slick, and most adhesives won’t stick to it. So you need this special formula.

In addition, because the patch was exhibiting curl at the top and side edges, and because I wanted something with quick tack, I used clear caulk (not pictured) along all the edges. This sets up quickly, and holds very tightly, even on glossy surfaces.

Patching Gap Around Light Fixture

November 8, 2019

The original light fixture had a rectangular base. The new one had a base that was barely larger than the electrical box. The electrician ended up with a slight gap on the left side of the box.

The wallpaper would most likely bridge that gap and look just fine. But since there was a slight difference in height between the wall and the base of the fixture, I wanted to close the gap to minimize chances of a visible pooch or bubble around the fixture.

I bought some drywall repair kits, and ended up using the one that had a thin aluminum mesh patch. I cut it to fit around the electrical box, using a few scraps to fill in gaps.

I then used drywall joint compound (“mud”) to smooth over the area. It took two of these skim coats, and a lot of time holding my heat gun to get everything to dry. Once sanded, it was nice and smooth.

A coat of Gardz penetrating sealer / primer, and the patched area was ready for wallpaper.

Elapsed time: Two hours.

This saved the homeowner having to hire “a guy” to do the repairs – and most likely, I would have had to “fine tune” whatever he did, anyway.

Repairing a Printing Defect

September 5, 2018

This custom-made “Meadow” wallpaper by Peter Fasano was very expensive, so I was disappointed to find a good number of printing defects in the material. I think it is digitally-printed, which is equally perplexing, because that process is much more precise than screen or block printing.

Either way, I encountered blurred ink, streaks, streaks of red running through the black & white print, and voids, like you see here in the top photo. This is one that I didn’t catch when I was hanging the paper (and you get to a point where you can only replace so many strips of paper, or you won’t have enough to do the whole room). The homeowner spotted it a few days later, so I went back to fix it.

Replacing the whole strip was too complicated (for many reasons) and would have used too much of their left over paper, and splicing in a patch would have damaged the wall surface, leaving it open to the possibility of curling edges. So I chose to do a patch. I could have simply cut a patch out of paper that matched the pattern of the flowers in the photo, but that would have placed a somewhat thick patch on top of the exisiting wallpaper. This would have been pretty unnoticeable, but I knew it would look better if the patch were thinner.

So I soaked the scrap of patch paper in water, and then worked carefully to remove the paper backing. Most wallpaper is made of at least two layers – the printed, inked layer, and the paper backing. Once I wet the paper backing, I was able to carefully and slowly peel the paper backing away from the inked top layer. See third photo. This process is a lot more delicate than it sounds.

Then I cut this patch to match the design on the wall, so the patch (now called an appliqué) would be as small as possible. See fourth photo.

Then I pasted the appliqué and applied it over the flawed area. Smoothed into place and wiped free of excess paste, the patch is invisible. See last photo.

Repairing Water Stains from Flooding During Hurricane Harvey

May 2, 2018


This home in Bellaire (Houston) received damage from flooding during Hurricane Harvey in August 2017. Water stains appeared on a small area of the wallpaper just above the baseboard in this powder room. Luckily, the homeowners had saved the paper left over from the original install, so I had material to use for the repair.

Certain substances, like grease, blood, smoke, rust, ink, tobacco, and water stains will bleed through wallpaper (and also paint and other materials, too). To prevent this, the discolorations must be treated with a stain-blocking sealer. Many of these are shellac-based, such as BIN, made by Zinsser, but there are others. I prefer oil-based KILZ Original (2nd photo).

I could have just cut some wallpaper and slapped it on top of the stain. But I wanted to be sure these flood survivors wouldn’t have to look at water stains again. So I used KILZ to cover the stains (3rd photo).

The next week, I came back to do the patch. Using my self-healing craft cutting mat with angles and measurements to trim on, along with a straightedge and razor blade, I cut appliqués to paste on top of the stained paper.

It wasn’t quite as simple as it sounds, because the wallpaper had to be hand-trimmed (use a razor blade to trim off the unprinted selvedge edge). And pasting the paper causes it to absorb moisture and expand, which can throw off the pattern match. So I was dealing with factors relative to what the other guy did and the products he used, compared to my own techniques and products / paste.

It took two tries, but with careful trimming and a little touch-up paint, the job turned out great (last photo).

I also used paint to cover some stains at the top of the baseboard, and also re-pasted some loose areas in other parts of the room (no picture).

A Small Repair Today – Plumbing Issue

March 15, 2018


This couple had water damage from Hurricane Harvey, and I repapered their powder room a month or two ago. Well, recently a pipe burst, and, long story short, they had to replumb the whole house. To run the new pipes, the plumbers had to cut holes in the drywall.

The top photo shows where the plumber patched a hole with a scrap of drywall. He left some irregular areas and rough edges that would show under the wallpaper. So I skim-floated over these areas and then sanded smooth, as you see in the second photo.

There was precious little paper left, so a patch was called for (rather than replacing the whole wall). From leftover paper that matched the pattern around the drywall patch, I cut along the pattern design (third photo). This would be less visible than if I cut a square patch with straight edges.

Once I put the patch into place, lining it up with the pattern on the wall, the repair was invisible. (The gap at the bottom will be caulked.)

Patching a Hole in the Wall

This bathroom had a ceramic toilet paper holder that was recessed into the wall. It was ugly, outdated, and in the wrong place (visible from the hallway), so the homeowners wanted to get rid of it. But that left a hold about 6″ x 4″ that would leave a dent under the new wallpaper.

The homeowner was running errands, so I asked him to pick up a piece of drywall that I could use to patch in the hole. Taping and floating can take a long time to dry, and I wanted to hang paper that day, so I used a different technique.

I cut the piece of drywall about 2″ larger on all sides than the hole. Then I cut off about 2″ of drywall all around the outside edges, leaving a chunk of drywall in the center that was just the size and shape to fit into the hole. I left the top layer of paper on the drywall, which formed a sort of flap all around the center piece. In the second photo, you see me removing some of the drywall, but leaving the inner section, and also leaving the paper flap.

In the third photo, I have inserted the drywall piece into the hole, and the flap is extending 2″ all around the piece. I have floated over the whole thing with joint compound. Next I set a heater and a fan on it, to get it to dry quickly, while other parts of the room were being prepped.

Once dry, I sanded it smooth, refloated to cover minor imperfections, and sanded again, then wiped off dust and primed. The last photo shows the final patch. If you didn’t know where to look, you would never notice it!

Some people get upset when there is a fair amount of wallpaper left over after the room is finished. This Clear Lake (Houston) couple felt the same, 15 years ago when I papered their kitchen and powder room. Well, come 2016, and the 40-year-old pipes in their ’70’s era home began to fail. Bottom line – they had to have the whole house completely re-piped. And to do that, the plumbers had to cut holes here and there in the drywall. When the drywall gets messed up, so does the wallpaper. Good thing they had extra wallpaper on hand!

The plumbers did a good job of patching the Sheetrock and then floating over the joints where the new patched-in drywall met the old. But there were still some areas that I needed to refloat and / or sand smooth, and then prime, before the wallpaper could be replaced.

The 2nd and 3rd photos show the soffit or fur down over the kitchen cabinets, first with the plumbers’ patch, and then with my new wallpaper repair.

The powder room had a swirly pattern, and had four walls that needed wallpaper repairs. In this room, as shown in the 5th photo, I appliquéd the new paper over the existing paper. Cutting along the design helps disguise the patch by eliminating visual breaks.

There is even a little paper still left over, in case another calamity strikes and more wallpaper repairs are needed. 🙂
