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.

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 .

Another Calm and Quiet Bathroom

January 29, 2022
Textured walls have been skim-floated and sanded smooth, wiped free of dust, primed, and are ready for wallpaper.
For the master bathroom, the homeowner again chose a symmetrical, fanciful, woodland themed design in muted tones of cream on tan.
The overall look is balanced and calm.
I added the paper towel cushions to the cabinet handles on the left, to prevent them from slamming into and marring the new wallpaper.
Close-up shows the unique light texture of raised ink on this material.
The manufacturer is Schumacher, pattern name is Chenoceau. Usually I don’t like this brand, but this paper was actually pretty nice to work with. It does not have a protective coating, so the homeowner will need to be careful with splashes of water and toiletries to prevent staining, and to not let damp towels hang against the wallpaper.

Calm Forest Frolic

January 27, 2022
Before shot of sink room in hall bathroom in a home in the Energy Corridor / Briar Forest area of west Houston.
Symmetrical flora and frolicking fauna are a popular design concept in wallpaper. Just about everything in this home is white or cream or tan, so the homeowner’s choice of this muted color palette fits in perfectly and lends a serene feel to the space.
Close up. The seam at far right is still wet, and will be less obvious once it dries.
The pattern is called Design Woodland and is by Crown Wallcoverings, a British company. True to its roots, the material is what we call a pulp, which is basically wood pulp and ink … thick, stiff, turns mushy when wet with paste, tears easily, and no protective coating on the surface so my client will have to be careful to avoid splashing toiletries or cleaning agents onto the wallpaper. Even water will stain it over time.

Mysterious Spot on Wallpaper – Air Borne Substances

January 3, 2019


If you look closely, you will see tiny tan dots all over this wallpaper. This is a paper wallpaper with a very light acrylic coating, that was installed maybe 30 years ago. The installer did a very good job – although he did not remove the previous layers (2!) of wallpaper backings, and did not use a primer.

I see spots like this almost exclusively in bathrooms – where you have enclosed spaces, toiletries, and humidity.

Since these dots are most prevalent around the upper areas of the room, I think they are stains from air-borne substances. However, an alternate theory is that they could be stains leaching through from the tan backing paper that was left on the wall, or possibly from the clay-based paste that was used for the installation.

Epounding:

My theory of air-borne substances is that if you spray something into the air, such as hair spray, air freshener, deodorant, or even onto a surface, such as glass cleaner, some of the substance becomes air-borne, hangs in the air, and eventually will come to rest on the walls. This results in perfectly round little specks on the walls. (See the Page to the right, “Care and Feeding of Your New Wallpaper.”

The stains could even be coming from cooking oils that splattered into the air, got sucked through the A/C ducts, and expelled into the bathroom.

Since this paper has just a light acrylic coating and no durable protective vinyl coating, most any substance floating around in the air would be able to land on the paper and penetrate into it, leaving these spots.

Don’t get me wrong – I MUCH prefer these thin acrylic-coated papers over thick vinyls and non-wovens. You just need to take appropriate steps to protect them.

Moving on…

Another possibility is because the installer didn’t remove the previous layer(s) of manila-type paper backing left from the original wallpaper installation(s), nor did he use a primer or sealer, it’s possible that chemicals from the old tan paper backing are leaching through onto the new wallpaper.

This is why art framers recommend acid-free mats and framing techniques. The same are available for wallpaper installations – but we’re getting into some pretty high-end topics now…

Getting back to our bathroom in Tanglewood (Houston).

Another very possible cause is the clay-based paste that was used to hang the wallpaper. I have seen many, many times, a “dirty,” tan discoloration coming through from underneath the paper, which I firmly believe is coming from the tan-colored clay-based paste that many installers like to use. I have many instances validating this theory.

The only discrepancy is that stains from the paste working their way through the wallpaper would not manifest as tiny, perfectly round specks, but as more generalized, mottled areas. Unless, the composition of the wallpaper included teensy dots in the paper fibers, intended to allow for porousity. Or humidity in the room forms miniscule droplets which land on the wall and then wick the tan paste up through the wallpaper. Which sounds reasonable to me. In fact, I like this theory a lot. And I really DISlike clay-based paste.

A final idea is that the wallpaper is just old. After 30 years on the wall, materials are bound to break down, humidity will take a toll, and it will be time for a change to a fresh new look.

Bottom line: Remove old wallpaper, properly seal and prime the walls, avoid clay-based pastes and instead use a clear wallpaper adhesive.

A Really Nice Textured Faux Grasscloth

September 27, 2018


I’m not a fan of grasscloth (read the page to the right), but there are wonderful alternatives – this product is about my favorite. The layers of string on the surface provide the texture that is so popular today, while the printed pattern mimics real grasscloth. Because the design is printed, it can be matched from strip to strip, so you don’t see the abrupt breaks between panels as you do with real grasscloth. It also has a bit of a protective coating, so it is more durable than the real stuff, too.

My only complaint is that this darker colorway tends to have some shading / paneling issues. In the fourth photo, you can see that the strip on the left is darker than the strip on the right. This happened on every strip, every bolt of paper, and some were worse than others; I had to discard two strips because of this. Interestingly enough, I have hung the lighter tan version of this material and did not have the shading issues.

I hung this in the hall bathroom of a home in the Meyerland area of Houston, that had been damaged by the flood from Hurricane Harvey in 2017. The house is a veritable temple to Mid-Century Modern, and the homeowner wanted the wallpaper to be era-appropriate to the style of the home.

This wallpaper pattern is by Wallquest, in their EcoChic line, and is in the Grass Effects book. It was bought from my favorite source for good quality, product knowledge, expert service, and competitive price – Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby. (713) 520-6262 or dorotasouthwestern@hotmail.com. She is great at helping you find just the perfect paper! Discuss your project and make an appointment before heading over to see her.

Soft Seafoam Toile in a River Oaks Powder Room

September 6, 2018


I loves me a vintage home! The sink and black & white tile floor in this under-the-stairs powder room were original to the 1945 home in the River Oaks subdivision of Houston. The homeowner appreciates traditional style, and fell in love with this soft charcoal-on-seafoam toile wallpaper pattern by Stroheim & Roman. I think it’s a perfect choice!

The walls were textured and had to be smoothed before the new paper could go up. (See other posts.) The wallpaper was thicker and stiffer than most, and so the seams showed more than I would have liked. Dim lighting in the room helped with that. 🙂 It also has no protective coating, so the family will have to be careful not to touch the wallpaper (such as when clicking the light switch) and not to splash water on it (such as when reaching for a hand towel).

The homeowner held the wallpaper for a long time before contacting me to “finally” get the room decorated and the paper up. Once the paper was up, both the wife and the husband exclaimed how much they loved the look, and that they needed to find more rooms to wallpaper!
