Non-Woven Wallpaper = Fibers

May 14, 2023
A somewhat new type of wallpaper , called non-woven ( also called paste the wall ), comes with many advantages.  Because it’s made of minimum 20% polyester content , it doesn’t expand when wet with paste like papers made of wood or cellulose pulp.  Nor does it shrink as the paste dries . 
Because of this trait, you can paste a strip and take it directly to the wall , with no booking / resting time .  This same characteristic allows you to apply paste directly to the wall , instead of to the back of the paper , if you choose.  This is sometimes a little faster and cleaner than pasting the paper .  And for a simple accent wall , you can roll the material out on the floor , eliminating the need for a work table .  (Still, I generally prefer to paste the paper.)
Another benefit is that this stuff is tough and strong , and when you’re ready to redecorate , it will strip off the wall easily and in one piece, with no damage to your walls .  (So say the manufacturers. 😊 )
One test to know if you have a non-woven wallpaper is to try to tear it.  If it’s hard to tear, chances are it’s a NW .   Also, sometimes those polyester fibers are very evident , as you see here at the top of this photo.  One of my colleagues likens it to fiberglass.  He may just be right!  

William Morris ‘ Fruit ‘ on Master Bath Accent Wall

February 21, 2023
A cozy nook. The homeowner likes to spend time here, soaking and relaxing. And recovering from supervising high school athletic activities !
This is a 1939 4-plex in the Montrose area of Houston that was beautifully renovated into a single-family home. So this entire master suite is carved out of what was originally one 1- bedroom apartment .
Note my white 2′ x 4′ sheet of plywood over the claw-foot tub , so I can safely access the wall above.
The wallpaper was placed on just one accent wall , above the tile wainscoting / chair rail . During the initial Sunday afternoon consultation , both the homeowners and I felt that this pattern on all the walls of this large master bathroom would be too overpowering . So they opted for just one accent wall .
The design doesn’t have a strongly noticeable secondary or vertical pattern , but I still took the time to center the most dominant feature (the pomegranates) on the tub faucet . The faucet guy , tub guy , and tile guy didn’t get everything perfectly lined up – but nobody’s even noticing. What matters is that the finished nook looks fantastic!
Also of note is that, in this near-100 year old home, the wall was bowed , and it wasn’t possible for the tile to lie flat against the entire surface. So there were some areas where the grout was 1/4″ wide, and some areas where the wall actually overshot the tile, leaving no visible grout at all. So at the area where the wallpaper met up with the top of the tile and the uneven grout line, I made a fat cut , to try to disguise the uneven line. Do a Search here to see previous posts on fat cuts .
This wallpaper design is by William Morris , who was a strong force during the late 1800’s and early 1900’s , in the Art Nouveau and Arts & Crafts movements . His work is having a resurgence in popularity right now. Most are more symmetrical and repetitive than this example ( Google Strawberry Thief ) , but, true to the design aesthetic , all of them involve natural elements , such as plants , flowers , fruits , birds , and animals .
In this close-up shot, you can see the raised ink of this print , which gives a slight textured feel .
The manufacturer is Morris & Co. Usually M&C prints on a user-friendly non-woven material . But in the last year or two I’ve come across more and more M&C that are printed on the old-fashioned, traditional, what we call a British pulp substrate .
Non-wovens are strong , durable , stain-resistant , humidity – resistant , easy to install , and easy to remove when you redecorate . Pulps , on the other hand , are just the opposite . Do a Search here to see my previous posts.
None of this is a deal-breaker. The installer just needs to know what he’s getting into, before taking on the project.
We hunted. This particular pattern was not available by any vendor in the NW material. Maybe it’s COVID , or supply chain issues , or maybe it’s a British thing (even though many American and Canadian companies are printing the Wm Morris designs ). Couldn’t find any outfit offering Fruit in non-woven.
At any rate, the paper went up beautifully, and the basic paper material will hold up well, even if the homeowner steams up the room on her long tub soaks , and the pattern is lovely in the vintage home with new tile , tub , and faucet .

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 .
The home is in the Woodland Heights neighborhood of Houston .

William Morris Pattern Makes for Welcoming Entry

August 20, 2022
Originally simply painted a rather dull and lackluster sorta orange, the homeowner chose this pattern to both brighten the entryway and make it feel welcoming.
Entry door wall primed and ready for wallpaper.
I love the columns on either side.
The black door and molding really stand out against the wallpaper.
The mom / grandmother described this as “elegantly soft.”
There will be artwork hanging on the walls, so it was important that the wallpaper pattern not overwhelm or take center stage. This Willow Boughs pattern will form a perfect backdrop for other focal points.
Close up.
Closer up, showing the light textured surface of this material.
The designer is William Morris , dating back to the late 1800’s and early 1900’s and the Art Nouveau and Arts & Crafts period. Morris & Co. is the manufacturer.
Morris makes two types of wallpaper – non-woven and the traditional British pulp . It’s important that this homeowner took my advice and selected the non-woven option. NW is much easier to work with. But also, since it has a high polyester content, it’s designed to strip off the wall easily when it’s time to redecorate . It also is stronger and more stain-resistant than most other types of wallpaper . That’s good, because this family has three little kiddies running around!
The home is in the Braes Heights neighborhood of Houston .

Period Wallpaper in Tower Grove House / Missouri Botanical Garden

July 28, 2022
Authentic furniture, and reproduction wallpaper reflecting the styles and tastes of the time.
This is a William Morris design , and reflects the Arts & Crafts and Art Nouveau design movement.
I believe this is also William Morris .
In the study , similar to the William Morris Willow Bough .
These wallpapers were probably made by the Morris & Co. brand. Their patterns are very popular right now.
If you go shopping, be sure to look for the non-woven or paste the wall material , not the historic British pulp paper.
This is the home of Henry Shaw , botanist. It was built in 1849 , with additions and changes over the years.

Finished Wall Re-Do – See Previous Post

July 26, 2022
Here’s the wall after I stripped, sealed, skim-floated, sanded, and primed it.
Finished. The birds in the pattern balanced nicely with between the ceiling line and the wainscoting.
I had more success with this install than the previous guy, due to proper prep, and also the material used this time was the user-friendly non-woven , rather than the old fashioned pulp type wallpaper the other guy had to wrestle with.
Strawberry Thief is a very popular pattern right now, and comes in many colorways. Do a Search here to see my other installations of this design.
There were some issues at the top of the wainscoting where the painters had used tape to mask off areas, long with caulk, an it left a rather large (1/8″) unpainted area between the wood molding and the wall. I filled this in with joint compound and primed it, and wallpaper would have adhered just fine. But that would have left a white gap between the wallpaper and the green molding.
I rummaged in my truck for the best matching paint I could come up with, and painted over the white edge. This would have left a bit of a thin brown line between the wallpaper and the green molding. It would have looked OK, but I had an idea to get rid of the gap altogether.
If I had used my regular thin straightedge (the red one), it would have let me trim the bottom edge of the wallpaper nice and close to the wall. But that would have left the aforementioned brown line showing.
So I used the metal plate you see at the upper right of the photo as a trim guide. It’s thicker than my red straightedge, and so gives a fat cut that leaves more wallpaper and less of that brown line.
In fact, the left edge, as you can see, is rolled, and that creates an even thicker edge to trim against, leaving even more wallpaper at the bottom of the cut. See the photo just above, to see how the wallpaper now completely covers the brown line.
These metal plates have a lot of other uses. They are made and sold by a fellow member of the Wallcovering Installers Association . She makes a lot of other cool tools, too. If you are interested, send me an email. wallpaperlady@att.net
The wallpaper design is by William Morris , a famed artist of the Arts & Crafts / Art Nouveau periods . The brand is Morris & Co.
This label is EXACTLY the same as the pulp material the original installer worked with – save for that one word non-woven . Be sure you get the non-woven version, which is also called paste the wall .

Wall Prep Ahead of Wall Re-Do

July 20, 2022
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.

Romantic Vintage Look Rose Bedroom Accent Wall

June 26, 2022
Textured wall has been skim-floated smooth , primed , and ready for wallpaper .
This pattern is called Smoky Rose and also London Rose . Both are appropriate!
Charcoal on an off-white background . Up close, it looks like water color strokes.
The wallpaper is by House of Hackney . Most of their wallpapers are the user-friendly non-woven material. This one surprised me being a British pulp. This is a rather old-fashioned basic paper material with no protective coating. It’s brittle when dry and gets soggy when wet with paste, making it tear easily or to drag when the razor blade runs across it. Definitely takes a different approach during installation .
I was lucky enough to have hung a pulp just the day before, so was in good practice!
Although not resistant to stains and tricky to work with, I do like the matt finish and how the paper dries tight and flat to the wall.

More William Morris Strawberry Thief in Houston Heights Hall Bathroom

June 24, 2022
Because I feared unstable walls in this 1920’s bungalow in this neighborhood (do a Search for previous posts), before hanging the decorative wallpaper, first I hung a non-woven liner paper on all the walls. That’s the white material you see in the photo.
The liner was hung horizontally so its seams can’t line up with the decorative paper. The idea is to disperse tension from drying wallpaper and changes due to humidity and etc., so as to deflect tension away from sketchy wall surfaces, and thus prevent delamination of multiple unstable layers deep inside the wall. Again, do a Search here to learn more.
Finished vanity area, with pattern centered on the light fixture.
Corner shot.
This colorful and symmetrical pattern is quite popular; I’ve hung it a number of times just this year.
Englishman William Morris designed wallpaper and fabrics during the late 1800’s and early 1900’s.
The styles then were Art Nouveau and Arts & Crafts. This design reflects a bit of each.
Wallpaper expands when it gets wet with paste, and then can shrink just a tad as it dries. The liner helps prevent that, but you can still end up with teeny gaps at some seams.
To prevent the white backing from showing through, I run a stripe of dark paint under where each seam will fall.
I use matt finish craft paint from the hobby store, diluted with a little water (in the orange bottle cap) and smeared on the wall with a scrap of sponge. Use a ruler or level and a pencil to mark where you want to stripe the dark paint.
Remember to allow for that expansion as the paper absorbs moisture from the paste. Meaning, if the paper is 20.5″ wide, and expands 1/2″, you’ll want to run your line at about 21.” And make sure that your painted swath is about an inch wide.
I also run a bit of dark chalk along the edges of each strip, to prevent the white substrate from showing at the seams (no photo).
Morris & Co. makes this iconic Strawberry Thief.
Interestingly enough, most times when I’ve hung a Morris paper, it’s been a non-woven paste-the-wall material.
Today’s option was a surprise – a traditional British pulp . This is a pretty basic and somewhat old-fashioned type of substrate . Sort of like construction paper, or the pages of an old family Bible .
The paper is very fragile , and can tear easily. You have to keep using new razor / trimming blades, because the material dulls blades quickly, and when dull they will drag and tear the paper.
Pulp papers also require a soaking / booking time after pasting , to allow time for the material to absorb the paste , soften a bit, and expand . The edges of the strips like to dry out , so I’ve learned to dip about 1/4″ of the booked ends ( booked means the pasted side of the wallpaper strip is folded onto itself, bottom edge folded up and top edge folded down to meet in the middle), into a bucket of clean water.
Then it goes into a black plastic trash bag to soak and relax for a few minutes before hanging. I use this opportunity to paste the next strip.
Non-woven wallpapers have advantages, because they do not expand when wet, and therefor you can get accurate measurements. They also can be pasted and hung immediately, with no waiting time. Alternately, you can paste the wall .

Another Installer’s Problems With British Pulp Paper

May 31, 2022
Scroll down a few posts to see where I hung this exact same pattern, and coincidentally just a few blocks away. I had absolutely no problems. Yet this poor installer struggled and ended up with many dissatisfactory issues.
In this photo, you see where the wallpaper has shrunk at the seams and left a gap, some tears, and a patch to cover a mishap.
More tears and gaps.
Paper coming lose from the wall. Not taking primer or paint with it. But you can see the adhesive clinging to the back of the paper. I’m suspecting this is clay adhesive. Nothing wrong with clay, but I prefer one of the vinyl-based adhesives.
Not sure what the guy used as a primer (if any).

This is the popular Strawberry Thief by William Morris , usually sold by Morris & Co. I’m believing the problem here is the material on which this pattern was printed.

The site from which this was purchased called it a ” heritage ” paper. It is, indeed, made of what we call a British pulp material. Old-fashioned, it is. These days, most wallpaper coming from the U.K. is printed on non-woven stock. The paper I hung a few days ago was non-woven.

Pulp wallpapers have a nice look. But they have no protective coating, so become soiled easily. They soften when wet with paste and tear easily, and can also shred under the razor blade while trimming. They expand when wet with paste, and then shrink as they dry, which often results in gaps at the seams.

Even skilled installers can have difficulties when working with this stuff. In fact, on the private Facebook page of the Wallcovering Installers Association ( WIA ), we have just been discussing this very same topic.

I believe this previous installer had a few shortcomings, such as lack of skill and maybe used the wrong or no wallpaper primer. But I think the real and unsurmountable culprit was the substrate.

Moral: If given the option, choose a non-woven material. They are made with minimum 20% polyester content, and thus are resistant to shrinking, tearing, and tension at the seams. Many other advantages, too. Non-wovens are also referred to as paste the wall .
