Dark Surface / White Substrate

August 21, 2018


Re yesterday’s post, because it was a dark pattern printed on a white substrate, I worried that some of the white backing might show at the seams. This is especially pertinent with thick papers and with papers that may shrink as they dry.

To help prevent any white from peeking out at the seams, I used a mud-hued artists’ pastel chalk to color the edges of the paper. In the top photo, you can just barely make out the line of muddy grey chalk along the right edge of the wallpaper.

This trick worked great. The seams pretty much melted together and disappeared. However, as you see in the second photo, there were a few sections where seams shrank and opened up just a tad – a half a tad. If the paper had a white background, you would never notice. But with a strongly-colored choice such as this one, you have to be prepared to see minute gaps in between the seams.

Dark Paper Bringing Brightness to a Harvey Hurricane Flooded Home

June 28, 2018


This home in the Bellaire subdivision of Houston was flooded during Hurricane Harvey in August of 2017. Everything below the 4′ high water mark had to be cut out and thrown out. The homeowners loved the Mid-Century Modern vibe of their 1952 home, so, as the structure was put back together, they re-created everything as accurately as they could – baseboards, doors, cabinets, flooring – they even found a funky green refrigerator designed in the style of what I can only describe as an old Studebaker sedan.

When it came to wallpaper, they wanted something to reflect the vintage vibe. After much research, they agreed on two papers from the Bradbury & Bradbury Vintage ’20’s collection. This colorful bird-flowers-and-foliage-on-black pattern went in their sun room, which can also be called the piano room.

The ’20’s Vintage wallpaper collection is pretty new from Bradbury and Bradbury, which is out in California. This company produces historic-styled patterns from eras such as Art Nouveau, Art Deco, Victorian, Asian, and more, right on through into the new offerings based on designs from the “Modern Age.”

Like many higher-end or specialty and / or “boutique” wallpaper brands, this paper came with a selvedge edge that had to be trimmed off by hand (by me!). The manufacturer’s trim guidelines were spot-on, and so the edges were nice and straight, and the pattern design matched from strip to strip perfectly.

This pattern is digitally-printed on a paper substrate with a somewhat shiny surface. I found that it accepted the paste (clay paste is recommended, to mesh with the paper which is printed on a clay-coated substrate) with no protests, and, after appropriate booking time, the paper handled nicely and the seams laid down nice and flat. That slightly shiny surface also allowed me to wipe any stray spots of paste off the surface.

Because the paper was black, I did take the extra step of using a piece of black chalk to color the edges of the strips, to keep the white substrate from peeking out at the seams.

This room holds a grand piano, and is in the back of the house, where it looks out onto the patio and backyard. It gets a lot of sunlight in the daytime, and the colors in the wallpaper will really stand out, and will bring a lot of light into this very deserving home.

Hygge & West Wallpaper – Curling at the Seams

Hygge & West, an on-line company, makes some darling wallpaper patterns. But I don’t enjoy hanging their papers. Because they use ink that fight the substrate it’s printed on, which causes curling paper and “pouched” seams.

Some inks smell like moth balls, and those tend to cause the curling problems. What happens is, the inked areas absorb moisture from the paste differently from the paper backing (substrate). The substrate expands, and that causes the paper to curl backwards. The second photo shows an extreme example of that.

Usually, once the paste dries, the paper shrinks back and the seams lie flat. But you can never count on that – the first photo shows a seam that has been on the wall for an hour or so, and the green ink is still curling away from the wall. The tendency is to keep pushing the seams flat – and that can cause overworking of the seams, stretching, burnishing, or other damage.

It helps to lightly sponge the face of the paper with water before pasting the back. This helps equalize the absorption of water, and evens out the expansion rate of the wallpaper. Make sure there is paste all the way to the edges of the paper – but not past the edge or onto the surface, which could cause staining. And use a little less paste on the edges, so it will dry faster and grab onto the wall. It also helps to stripe the wall behind the seam with a roller of paste – not much, but enough to put a layer of paste onto the wall, which can be drying and tacking up, ready to grab onto the edges of the strip of wallpaper.

Jungle Book / Beverly Hills Hotel / Tropical Foliage

December 20, 2017

I hung wallpaper in this bathroom about 15 years ago. The girl has grown up and gone off to college – and it’s time for her room to get an update.

This banana leaf design is by Nobilis. Tropical greenery is a popular concept, and there are lots of manufacturers making similar patterns; you can find something beautiful at any price range.

This Nobilis product is printed on a non-woven substrate. It is meant to be a paste-the-wall installation, but I preferred the flexible handle-ability I got by pasting the paper instead. In addition, because the manufacturer printed the dark paper on a white substrate, it was highly likely that the seams would show up by hair-bredth gaps.

I used a black chalk pastel to color the edges (where the dark blue crossed the seams), to prevent the white backing from showing – and they disappeared. I didn’t have a green chalk stick, so left the green leaf areas untreated … so the seams did show a bit more. But visible seams are pretty expected with dark papers, and with thick non-woven materials.

Rounded Flame Stitch in a Heights Dining Room

This dining room in a new home in the Houston Heights has traditional block paneling that reaches up 5′ high. In the first photo, you see the painted paneling, and the new Sheetrock above it. I primed the Sheetrock with a pigmented wallpaper primer (Ultra Prime Pro 977 by Roman’s), and then every surface in that room was – WHITE!

And it was – BORING! 🙂

In the next photos, you can see how wallpaper transformed the room. The pattern is small an tight and contains only two similar colors on a white background, so it is not busy or overwhelming at all.

But just look at how that little bit of pattern and color brings life to the room! And look at how the paneling and woodwork suddenly becomes noticeable and beautiful, once it is contrasted against the darker wallpaper.

The interior designer who helped bring life to this home is Stacie Cokinos. The wallpaper is in the Echo line, and is by Baker, a British company. It is on a non-woven substrate, and is a paste-the-wall product.

Unhappy – Visible Seams Today – But a Solution

I don’t often work in offices or businesses or commercial spaces, but today I did take on a job in an office park (photo 1) off Westpark & Chimney Rock in southwest Houston. It was a pipeline company that was spiffing up their offices, and everyone who worked there was positively delightful.

The wallpaper, however, was not quite so agreeable.

In the second photo, you see the painted wall before I got started. I rolled on a coat of Gardz, a clear primer. Then started hanging this small herringbone pattern by Schumacher. Although I followed the manufacture’s instructions to reverse-hang the goods (a trick to minimize color variances by hanging every other strip upside down, so you are placing the same sides of the wallpaper next to each other – it’s easier to understand if you are actually doing it, rather than typing it. 🙂 )

Anyway, as you can see in the next photo, there is a visible vertical 1/4″ wide line down each seam, between each strip of wallpaper.

I didn’t think it looked good, and the other guys working on the jobsite noticed it, too, so I called the interior designer, who called the clients. Bottom line: Although we all acknowledged that it didn’t look great, it wasn’t horrible, and besides, there would be furniture and a large painting on that wall, which would pretty much cover the white lines, as well as distract your attention to more interesting things (the oil painting).

So, they gave the go-ahead to continue hanging the paper. Still, I thought it could look better.

I was unable to remove the four existing strips, due to surface failure when attempting to pull those off the wall – Meaning, when the wallpaper, which is on a non-woven substrate, which is designed to strip off the wall easily and in one piece with no damage to the wall, when I pulled it off the wall, some of the paint came away from the wall, too, leaving an uneven surface on the wall, which would leave dips and bumps under the new wallpaper. I had Gardz’ed the wall, so I thought the surface was stable. But if the paint beneath my primer is not sticking to the drywall, or if there are many layers of paint and they are not all compatible, or dust, or crumbling paint, or who knows what, you can have layers delaminating (coming apart), which is what I had today.

Long story short, I thought the white vertical lines looked better than crumbling walls and bumps under the paper. So I left those strips up on the wall, and focused on the remaining five strips.

Since it was a pattern that allowed it, what I did was, instead of using Schumacher’s factory cut edge, I used my 6′ straightedge and razor blades to trim off 1″ or so from either edge of each 9′ strip of wallpaper, making sure to continue the reverse-hang rhythm, while also making sure the “up” or “down” angle of the herringbone pattern lined up correctly with the pattern on the strips on either side.

This was tedious, but it proved to be the right solution. If you really looked at the wall, you could still see some of the seams, and there was still a bit of white discoloration. But the overall effect was MUCH more pleasing, and definitely worth the extra effort. Unfortunately, I didn’t get a photo of the finished wall with the hand-trimmed wallpaper.

Interestingly, if you look closely at the “before” photo (#2), you can see a faint vertical white line on the painted wall, before any wallpaper even went up.  This supports the designer’s theory that the strong fluorescent light is at least partly to blame for those white lines.

The interior designer for this job is Janet Dowlearn.

Another Reason I’m Not Thrilled With Non-Woven Papers

August 30, 2015

Wallpapers printed on non-woven substrates are becoming more and more popular with manufacturers. They are aimed at the DIY crowd, I think, because they are supposed to strip off the wall easily when you want to redecorate. (Although that is only quasi-true.) And they are often installed by pasting the wall, rather than the back of the paper, which is supposed to be simpler. (Whoever pushed that theory never put wallpaper behind a toilet or around detailed moldings.)

There are various types of non-woven substrates. I like the thinner ones OK. This particular one is thick and spongy. It’s hard to push into detailed areas or corners, making trimming difficult and imprecise. And the littlest movement or force can cause it to crease or become mashed. The crease in the photo happened when I simply picked up a strip of paper and the top half flopped forward. It’s likely that this crease will not be noticeable once the paper is up on the wall and dry. But, still, it might show.

Many of the thick, stiff non-wovens have visible seams. This one was thick, but it was soft, and I was really pleased with the seams – positively invisible.

Changing What I Did

I hung this reddish faux finish wallpaper pattern a few years ago on the bottom of the walls in an entry in a 2-plex in the Rice University area of Houston. Some workmen bopped the walls and caused damage to the wallpaper (Photo 1). I told the homeowner that I thought I could touch up the dings with paint, but she opted to have the whole room redone.

In Photos 2 & 3, I have started stripping off the original wallpaper. (See step-by-step instructions on a “How To” page on the right.) The top inked layer has been wet, and then pulled off, and you see a little of the white substrate still clinging to the wall. This layer gets soaked with a wet sponge, and it pulls off easily, with little damage to the walls. The main reason this went so well is because I prepped the walls with a good primer. When people hang wallpaper without a primer, removal can be much more difficult, time-consuming, and cause damage to the walls.

In the next shots, you see the new paper. This was hung below an oak wainscoting, and there was oak trim and oak flooring of the same color at the bottom of the wall.

At first, I was dubious about the blue color with the brown wood, but once all the walls were finished and I stood back and looked at it, it looked great!

This wallpaper pattern is by Designer Wallpapers, and was bought at a discounted price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby. (713) 520-6262 or dorotasouthwestern@hotmail.com. Discuss your project and make an appointment before heading over to see her

Flaw of the Day – Banged Edges, Dirty Edges, Spot, Blob

October 13, 2012

I hung this same paper a few weeks ago, and blogged about it. The first shipment of that order, the patern match was off, so we had to send the paper back and get a new run.

Today, this batch matches just fine. But there are a few issues … For starters, my never-ending rant about banged edges. This paper was shipped in a bag, not a box, and with no cushioning around the ends of the rolls. On a thinner paper, the banged edges usually pull flat to the wall and disappear, and with a busier pattern, they are not so noticeable

But with this very plain pattern, and the thick “non-woven” substrate, the banged edges are fairly visible. Still, these are relatively minor, and not noticeable when viewed from a distance – plus, the homeowner was very eager to finally get her bedroom finished and back together – so I went ahead and hung this paper.

The first pic shows not a banged edge, but a weird impression – probably done at the factory by something pressing into the material, or possibly during shipping. Whatever it was, the imprint is pretty visible, if you ask me. I was able to cut around a few of these imprints, but had to put a few on the wall, because there was precious little paper to play with.

In the second photo, there is a weird blob in the material. I think that something pressed against the paper during processing, and pooched that area out a little, as it seemed to have delaminated from the backing. It was farily low on the wall, and not real major, so I left this strip in place.

In the second photo, also, you can see that the seams on this thick, somewhat spongy non-woven paper are fairly visible, depending on the lighting. This was a little bothersome to the homeowner on my previous job.

A few weeks ago, I bid a job where the homeowner was looking at another thick, spongy, plain (no pattern) paper, and I told her that the seams would probably be equally visible. She listened, and decided against that sort of paper, looking instead for a thinner material printed on traditional substrate (as opposed to these new “green” non-woven materials).

People often remark that I’m too picky. But I DO see these things, even if the homeower does not. And I think that if you are spending a lot of money for the paper, and paying me good money to put it up, then you ought to get top-quality merchandise, not stained or bashed goods. Likewise, I have the responsibility to do my very best to be sure it’s put up properly and cleanly.

Moving on.

In the third photo, you see how even a small banged edge does show up when the strip is placed next to another on the wall. In addition, there is a teeny blue dot on strip on the left – lower right quadrant. This wasn’t too noticeable.

However, the first strip I put up had two brown smudges on the right edge, and they DID show up, when the next strip was placed next to it. I had to pull it down and replace it. We were very tight with paper on this job, but luckily there was enough to replace this one strip. And you can bet that I counted and measured and plotted, before going ahead and ripping that stained strip off!
