Whimsical Arabian Nights Dance in Powder Room

January 13, 2023
You’ve got to look at this close-up, to notice the antelope and flames / foliage .
You gotta make a decision … The light sconces (they are currently removed, but you can see the electrical boxes where they will be placed) were centered on the vanity top, but the faucet was off-center by about an inch. So I chose to center / balance the pattern on the sconces and countertop. The mirror will be hung between the two light fixtures, so we’ll end up with a pleasing, balanced look. The faucet isn’t exactly in the middle of the design motif, but no biggie – there’s going to be a mirror there, anyway.

Although the website specs said this is a pre-trimmed non-woven material , that was incorrect. Turns out it had an unprinted selvedge edge that had to be trimmed off by hand . Here I’m using my straightedge and razor blade to remove this selvedge. This takes precision and a LOT of time .
The manufacturer usually provides trim guides to help you know where to cut. But it’s usually better to trim to the pattern – determine an element in the design motif that will meet up with the corresponding motif on the opposite side of the strip when the strips are hung on the wall, and use that as your guide . Be sure to trim off the trim guide marks, or they will show on the wall.
The pattern is called Arabian Nights and is by Relativity Textiles . I’ve never worked with this brand before. I was not pleased . In addition to the incorrect information about the pre-trimmed paper , the mfgr’s specs said this was printed on a non-woven substrate . It was not. It wasn’t even printed on standard wallpaper stock . Instead, it was a pulp material – This is a sort of old-fashioned wallpaper , and is very brittle and prone to tearing and dragging (your trimming knife or razor blade will get snagged and you’ll end up with a ” chewed ” jagged cut, instead of a crisp cut . It also tears easily. It also has no coating, so it’s not stain-resistant … Not good in a busy household with a 3-year old toddler , or anyone splashing water or soap or air freshener .
It was also difficult to hang . Applying wet paste to the backing causes the substrate to absorb moisture and expand at a different rate from the ink on the surface. So you end up with wrinkles , waffling , and quilting .
Sponging a light bit of water on the front before pasting helps even out the moisture differential and ease installation . I’ve never before encountered a pulp that had this type of ink on the surface. One clue for this bad stuff is when you open the package and it smells like moth balls . Once I figured out how to work with it, , it went OK – although tedious . The seams did look very nice.
BUT … all this effort would have been unnecessary and the finished room would be more durable if the mfgr had printed on a non-woven substrate (as their on-line specs stated) and had used standard inks instead of this weird , smelly , high-end stuff. In fact, the material would have cost the homeowners a whole lot less $ if it had been normal ink on a non-woven backing .

Heavily-Inked Papers Need Extra Moisture

August 13, 2022
Something smells like moth balls ! Some high-end hand screened wallpapers are printed with what we call stinky inks . These inks often fight with the substrate they’re printed on. The backing of the wallpaper will absorb moisture from the paste and expand , but the ink on the surface won’t, so you end up with what we call waffling or quilting . Wrinkles in the wallpaper in between the printed inked areas. Do a Search here to see photos and read more about this.
You can reduce or eliminate this by evening out the moisture between front and back. It’s as simple as taking a very lightly damp sponge and wiping the front printed surface of the wallpaper. Then paste the back as normal , book (fold pasted side to pasted side), roll up, place in black trash bag for a few minutes.
Now the wallpaper should be relaxed , and the wrinkles should be evened out . Now you’re ready to hang wallpaper !
This pattern is called Les Touches and is by Brunschwig & Fils , a higher-end designer type brand .

Stinky Ink = Curling Seams

March 25, 2018


Some higher-end wallpapers are screen-printed with an ink that smells like moth balls. We call this stinky ink. And it’s a stinker to work with – because the edges curl badly. The inked surface of the paper absorbs moisture from the paste differently from the backing, so the backing swells and expands, pushing the inked surface away… resulting in curled edges. The top photo shows the edges curling on the pasted and booked strip, and the second photo shows the edges curling on the wall. I tried a lot of tacts, but could not get the seam to lie down.

This paper has a selvedge edge that is to be trimmed off by the installer(straight edge and razor blade and a steady hand). When I tried this standard technique, the seams curled and would not lie flat.

So I tried another approach. I put the pasted but un-trimmed paper on the wall, and then used the double-cut technique. A double cut is essentially a splice – you position one strip, then position the next strip, overlapping an inch or so of the second strip vertically over the edge of the first strip, all while lining up the pattern.

More clearly, you’re overlapping the left edge of the new strip onto the right edge of the existing strip.

Then, using the custom-made trim guide tool seen in the photo, and with a strip of 3″ wide heavy polystyrene plastic (called a Boggess strip, after the guy who invented and sells it) on the wall to protect it from being scored, I used a new single-edged razor blade to carefully cut through both layers of wallpaper.

In the third-to-last photo, I am removing the excess paper left at the seams after this trimming. In the second-to-last photo, I am smoothing the paper back into place. It’s also important to wipe off all paste residue left on the surface of the paper.

Who knows why, but this technique results in nice, flat, tight seams, with edges that do not curl.

Same paper, same paste, same wall – but no curl. Go figure.

Double-cutting takes more time, patience, material, and equipment. But when it’s called for, it might be the salvation for a contrary paper.

New Wallpaper in the Wallpaper Lady’s Bathroom

Last week, I stripped off a decade-old botanical and bird wallpaper pattern from my master bathroom, and replaced it with this “Raspberry Bramble,” by Bradbury & Bradbury (http://bradbury.com/), a California-based company that specializes in patterns true to the Art Nouveau and Arts & Crafts and Victorian periods, along with some Mid-Century Modern and other designs.

This B&B wallpaper was a little tricky to work with. For starters, it has to be hand-trimmed (see photo) to remove the selvedge edge. My go-to pre-mixed adhesive is not a good choice for this material, so I chose a potato-starch paste available from Bradbury, that comes powdered and is mixed with water on-site.

This particular pattern has a lot of ink (smells like moth balls!) on the surface, and, when paste is applied to the back, the backing absorbs paste and swells at a different rate than the inked surface, resulting in wrinkles and bubbles and twists, plus the curled edges you see in the photo, which can prevent the seams from lying down properly. The moisture differential can cause the paper to continue to swell on the wall, causing wired (overlapped or puckered) seams.

I’ve hung a good amount of Bradbury & Bradbury papers, but had never encountered the degree of bubbling and curling as with this paper.

The solution to all this is to mist or damp-sponge the surface of the paper, which puts moisture on the front, and allows the front and back (wet by the paste) to absorb moisture more evenly. Then the paper is folded loosely (booked), and also rolled up like a newspaper. This helps push the curled edges back down. Then the strip of wallpaper is placed in a plastic trash bag to sit for 10-15 minutes, much longer than the booking time for most papers.

All of this took more time, but it resulted in smooth paper with flat seams.

My plan for this room is to achieve a 1700’s French chateau look, so I am also darkening and stenciling my vanity, which has a new “Noche” travertine countertop, will be hanging some frilly antique wall clocks, period artwork, a beautiful chandelier, and adding other features.
