Fanciful Mural for Baby’s Crib / Accent Wall

December 23, 2022
Typical textured wall in new homes in suburban Houston has been skim-floated , sanded smooth , and primed with Roman Pro 977 Ultra Prime wallpaper primer .
All ready for baby Noah! The parents-to-be will spend the weekend bringing in the crib and other furnishings .
This is a 4-panel mural . Here I’ve laid out the panels , to ensure correct placement , and get accurate measurements .
We had some ” issues ” and I wasn’t completely happy with this product / vendor . For starters, they custom-printed custom-sized the material to the exact dimensions I had asked. Problem is, these panels are intended to be overlapped and double-cut ( spliced ). That means losing an inch on every seam . The company should have accommodated for that by providing us with four extra inches. They did not, so I had a real math and juggling match trying to plot how to get enough paper to cover the width of the wall.
The grey colors go nicely with the current trend toward greys and beiges ; the rest of the home follows this color scheme .
i thought this was going to be a pre-trimmed non-woven / paste the wall material. I was caught off guard when I discovered it was a textured vinyl on a paper backing , untrimmed and had to be double cut . See other post and/or do some Searching here for more info on this DC process . I think a better material would have resulted in better seams . But – wallpaper is meant to be viewed from about 5′ away, and from there, the wall is perfect.
Remember the picture of the panels laid out on the floor . The panel on the far right had a cool train near the top. It was a prominent feature in the scene . But, as you see in this photo, that train was cut off by the door. So all you see over the door is blank sky . I really liked that train, and so did the mom . I wanted to put it where she could see it .
So I took the bottom portion of that last panel and found the train. I used a straightedge to cut the bottom edge, and then used a scissors to trim around the top of the train and its trail of smoke .
Vinyl is slick , and wallpaper paste won’t adhere to it. So I applied special paste designed to grab ahold of vinyl. Then I placed it over the door , butting it up against the right where it meets the adjoining wall.
But – dangnabit! I forgot to take a picture of it finished! It looked great. Over the door was no longer all that dead-air blank space. Now there is a streamlined train with wisps of smoke , heading toward the distant castle !
I’m not going to mention where this was purchased from, because it’s one of the sites that I hope people will steer away from – a place that sells batteries , jewelry , fishing tackle , and – oh, yeah – wallpaper, too,,, you’re just better off with one of the established companies that specializes in wallpaper .

Bringing India to Houston

July 4, 2020


One of the homeowners has familial ties to India, and he wanted their new home to reflect that feel. Presenting “Peacock Garden,” which perfectly conveys the feel of rural parts of that country, while complimenting the colors of their dining room.

This wallpaper is 54″ wide – which is about as wide as I am tall! Since I don’t have scaffolding, I used two ladders, set close together (not pictured), so I could walk back and forth between them to augment my wingspan.

The paper was untrimmed – had a selvedge edge that had to be roughly trimmed off by hand. Next, a perfect pattern match was achieved by overlapping the seams on the wall and double cutting – an industry term for splicing. The process requires special tools, and takes a good bit of additional time. Do a Search here to find related posts.

The material is a durable non-woven, which meant that I could install via the paste-the-wall method. Eliminating paste from the back of the paper made each 54″ x 10′ strip much lighter and easier to get to the wall.

The contemporary home is a new build in the Montrose neighborhood of Houston.

This wallpaper pattern is by Zoffany, and 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.

Warping Wallpaper – Grasscloth

June 17, 2020

Well, this was a first for me. I can’t say that I remember having a grasscloth that stretched and warped out of shape this badly.

What’s odd is that, after I pasted and booked the wallpaper, it was perfectly lined up and flat. It was only after the paper had sat for the resting period, and then I unfolded it and took it to the wall, that it started warping out of shape.

My first strip laid against the wall nice and flat, but did not line up against my laser level’s red beam, moving to the left the farther down the wall the strip went. The subsequent strip to its right, naturally, would not butt up against the first strip. However, this second strip did line up against the laser plumb line, on both the right and left sides. So I left it on the wall.

But I had to tear off and discard that first strip.

I had problems with many of the strips. As you can see, there was major warping and wrinkling. I was unable to smooth out most of these warps.

Some of my colleagues have suggested that my trimmed edges were not straight. And I admit that I sense that my ($200!) straightedge is not true (perfectly straight). But a 1/8″ discrepancy over a 9′ drop should not result in wrinkles of this magnitude.

I think that the substrate that S&L is using is absorbing moisture from the paste unevenly, and thus creating the warps and twists.

The only way I could make this work was to do a double-cut (spliced seam). I smoothed the grasscloth onto the wall as best I could, even though both the right and left edges still presented wrinkles.

I carefully pulled away from the wall the left edge of the previous strip (having applied extra paste, to keep everything wet and “open”). Between that edge of the strip and the wall, I placed a “Boggess Strip,” (invented by a fellow WIA member) which is a thin strip of 2″ wide polyethelyne plastic, that will protect the wall from my razor blade.

Now hanging the next grasscloth strip, I then covered the underside of the right (wrinkled) edge with blue plastic tape (also invented by the same WIA genius member). This would keep paste off the surface of the strip I was overlapping it onto. Then I smoothed the paper onto the wall, allowing the right side of the strip to overlap on top of the previous strip, by 1.5″.

I worked out wrinkles as best as I could, but some insisted on remaining. I then took my EuniTool straightedge (invented by yet another WIA member), and used it as a guide, along with the red light line from my laser level, and a new, fresh razor blade, to cut a straight, plumb line between the edges of the two strips.

The grasscloth was thick, and I had to press really hard to cut through both layers. The Boggess strip prevented scoring into the wall. This is important, because an un-intact wall can delaminate under the stress of drying / shrinking wallpaper, and this can cause the seams to pop open.

Back to the double-cut. Once the cut was done, I removed the plastic Boggess strip from the wall, and the protective blue plastic tape from the edge of the grasscloth, as well as the two excess strips of paper that I had just cut off. (Do a Search here to see pics and read more about the double cut / splice process.)

I could then smooth the newly-cut edges of the two strips together.

All this takes a lot of time.

I still had more strips to hang – and each required the same procedure. You only have so much “open” time before a piece of wallpaper starts sticking to the wall and cannot be jacked around with anymore.

I had to jump to the left edge of the current strip I was working with, and add a Boggess strip behind it. And then I had to paste and book my next strip, and apply some blue tape to the area that would overlap the previous strip. Wait a few minutes for it to book and absorb the paste.

Then repeat the double cutting procedure used on the first strip.

All this caught me off guard, and it threw off my engineering of the wall and my planned width of the strips. It also took a lot more time … I spent 5 hours hanging just these 5 strips.

Bottom line – I got ‘er done … But I am definitely NOT going to recommend Serena & Lily grasscloth to future clients.

And I am VERY grateful to my WIA colleagues for inventing tools and gadgets that help with these tricky situations, which I’m glad I bought and had stashed in my van, and for sharing their knowledge and experiences so I knew what techniques I might try.

Schumacher Pyne Hellyhock Hell

March 22, 2020


Pardon my French, but we don’t call this company “Schitmacher” and “Poomacher” for nothing … With so many quality substrates and inks out there, and so many other companies making top-notch papers, why, oh WHY does Schumacher continue to use outdated materials and methods – especially when they’re crappy?!

The wrinkles here are referred to as “waffling” or “quilting.” This is caused by the wallpaper backing (substrate) absorbing moisture at a different rate from the ink on the front. This moisture causes the substrate to expand more than the ink, which creates wrinkled areas.

I had this problem with the Bibliotheque I blogged about last week. But that was not as severe, mostly because the inked area covered most of the paper.

In this Pyne Hollyhock, most of the ink is concentrated down the center of the strip, leaving large un-inked areas along the outer edges.

I was able to smooth out many of the smaller wrinkles in between the blue flowers. Others may disappear when the paper dries.

But the blank / white areas had wrinkles so big that they would not be smoothed out. See third photo. The other thing is, because this white area was twisting and warping so dramatically, you can bet that the edges of the strip will not butt up properly with the next strip.

Sometimes you can double cut (splice) seams that are not butting up correctly. But since this paper also presented the huge wrinkles, it still is gonna look bad at the minimum, and have large gaps at the worst.

A liner might help (do a Search here), but I doubt it would tame the worst wrinkles, especially at the edges. In addition, it adds more material cost and at least another day’s labor.

I did a couple test strips, employing different approaches with each. Such as dampening the front before pasting to even out the moisture distribution. Booking for extended lengths of time. Booking and then opening and repasting. Different smoothing techniques. I even got out the heat gun to speed up drying to see if the wrinkles would flatten.

But I never got a result that I felt was acceptable. And certainly not what this family deserved, nor worth the price they paid for this so-called high-end brand.

It’s not often that a paper beats my butt, but I did end up throwing in the towel on this one.

Too bad, because the homeowner and interior designer really love the pattern, which is one of Schumacher’s most popular. Right now, it’s undecided if they will see if one of my buddies wants to tackle it, or if they will choose something else.

This was to have gone in the dining room of a newly renovated home in the Woodland Heights of Houston.

Bibliotheque Install Details, Pt I – Hand Trimming, Overlapping

March 18, 2020

Like many of the higher-end brands, this Brunschwig & Fils wallpaper had to have its selvedge edge trimmed off by hand. Unfortunately, they did not provide trim guide marks. Double unfortunately, I tried using the pattern as a guide, but, for a lot of reasons, this was a big fail – the edges looked like they had been trimmed with a hair curling iron. 😦

How, then, was I going to get good seams?

I was preparing to double cut (splice). But for many reasons, this was not presenting as a good option.

Then I got the idea to overlap. This turned out to be the perfect solution!

The edges of the “bookshelves” were not straight, so, instead of using my straightedge as a trim guide, I grabbed a new razor blade and free-handed my cuts along the design. (see top photo)

Then, after measuring, pasting, and booking my strips, I positioned them on the wall by overlapping one “shelf support” on top of the previous one. The second photo shows one strip being placed thusly.

Overlapping like this does leave a ridge under the wallpaper. But it is not very noticeable, especially since my design motifs were perfectly aligned.

What’s even cooler is that this overlap added a bit of 3-D to the room, which is what you would have if you had real wood and books in there.

Another advantage is that I could tweak the spacing if needed, to plumb up a strip that might have started going crooked.

Faux Agate Kill Point Over Door

December 1, 2019

When you hang wallpaper around a room, the last corner virtually always ends up in a pattern mis-match, because the last strip will be split vertically to fit gap between it and the first strip that was hung. The pattern on it won’t line up with the pattern on the first strip that it is butting up against. Difficult to explain.

Anyway, as you see in the first photo, if I had let this be the last corner (the kill point), the horizontal lines would not line up as they do in the photo, and there would have been an 8′ high, eye-jarring mis-match of lines.

So I chose to put the kill point over the door, an area that is only 7″ high, and that not too many people look up at.

The pattern came together over the door pretty nicely, but the design on the left piece was a bit higher than the design elements on the piece on the right, so there is a bit of a mis-match.

If I could bring the design on the left down a little, it would match up much more nicely with that on the right.

To do that, I took a straight edge and a razor blade and trimmed off a wedge-shaped sliver of paper from the left edge. The wedge was wider at the bottom than at the top. This created a gap at the bottom of the strip. When the strip was positioned to where it butted up against the previous strip, closing that gap forced the upper portion of the strip to lean downward, which brought the horizontal lines on the left strip down to where they met up nicely with the horizontal lines on the right strip.

At this point, the left strip is overlapped on top of the strip on the right. The thickness of the under-lying strip shows as a ridge under the upper layer of paper. I would have been OK with this, because the strip is over the door where no one is going to be looking.

But I thought I could make it look better.

So I did double cut. A double cut is a paperhanger’s term for a splice. Before cutting through the two strips of overlapped paper, it’s important to protect the wall, because if the wall gets scored into, when the wallpaper dries and pulls taught, the layers of paint and drywall and etc. inside the wall may give way (delaminate), and leave irreparable curls at the seams.

In this case, I used a few layers of scrap wallpaper placed behind where I would make my splice. So when I cut through the two left and right pieces of wallpaper, my razor blade did not go all the way down to the wall surface.

Once the cut was made, I removed the cut-off remnants on either side of the cut, and smoothed the remaining paper into place. As you can see, the pattern now lines up pretty darned well.

There were still a few lines that didn’t match up, so I took my trusty No. 2 pencil and drew a few “enhancements.” Voilà!

Good Catch After a Mistake

November 19, 2019

Whoops! Somebody (me 😦 ) cut a wallpaper strip to 6’24” instead of 6’34”.

This William Morris wallpaper is expensive, and I didn’t want to just throw away the too-short piece. So I figured a way to use scraps to save it.

At the bottom of the too-short strip, I trimmed horizontally along an element of the design. From the scrap pile, I found a piece with a corresponding pattern, made sure it was the right length to reach the baseboard, and then trimmed the top horizontally to match up with the design on the piece already on the wall.

The reason I trimmed along the swoopy line of the design is that I wanted to eliminate a straight horizontal ridge showing under the two strips once they were overlapped on the wall. The eye might notice a wide, non-conforming, horizontal ridge, but it won’t notice a narrow overlap that follows the contours of the pattern.

I put the short strip in place, and the pattern matched perfectly.

But there was a slight sheen from above, glinting off of the cut edge of the wallpaper in just a few spots. You can just barely see this in the second-to-last photo.

So I pulled the two strips of wallpaper apart and put them back together, but reversed the sequence, overlapping the top strip onto the lower strip. Now there was no cut edge for light to catch or bounce off of, and now the overlap / ridge is completely invisible.

Note that the surface of this wallpaper was a vinyl (plastic) material. Wallpaper paste won’t stick to plastic very well (it’s too slick). There is a special adhesive called VOV – for Vinyl Over Vinyl – formulated to make this bond. But I don’t always trust it.

So I often use clear caulk, which I call Super Glue for Wallpaper. Under the right conditions, it’s a wonderful solution.

Note: There is a technique called a double-cut, which is a method of splicing two strips of wallpaper together. A double-cut eliminates the possibly-visible ridge that you get when you overlap strips of wallpaper. For various reasons too complicated to get into here, in this case, and especially down low and behind the toilet, I preferred to use the overlap-and-super-glue technique.

Fudging The Pattern To Make It Look Like It Matches

June 15, 2019


Top photo – this wallpaper has a subtle stripe pattern formed by vertical blocks of squares. As I mentioned in the previous post (below), I centered the white stripe pattern on each wall. And that meant that as the wallpaper moved its way across the wall and up over the doorways, the squares making up the pattern would be out of sequence as they met in the center over the doors, resulting in a pattern mis-match.

To further complicate things, I felt the room would look better with the white stripe also centered over each doorway and window.

My challenges were to:

~ Keep the squares positioned so the horizontal lines of the pieces over the doors aligned with the horizontal lines on the full-height strips to either side. That was harder than it sounds, because on two of the doorways, the center point where I started was 6′ away from the target I was trying to line up with. In some cases, I trimmed the edge of a doorway header strip every so slightly at a diagonal, so as to move that top line of the square up or down, so it would match up with the target line.

~ Keep the pattern inside the squares looking like they were following the original sequence. In other words, I didn’t want a tan square to land abruptly next to a white square. All those squares had to ease into one another. The pattern was a bit forgiving, because the squares were of varying widths, so the eye wouldn’t notice if some were wider or narrower than originally printed. So I used a straightedge and razor blade to cut some of the header strips apart vertically, eliminating tan or white squares as needed. I could also cut some additional squares and insert them in between strips.

If this were a thin paper-paper, I could have simply trimmed along a vertical line and then overlapped the two pieces. But this non-woven material is thick, and an overlap would show, probably even from 9′ up and over the door moldings. So I used a double-cut (splice) technique.

In the photo, you see the opening I am trying to bridge. In the next photo, I have positioned a piece of paper so that it lines up with the horizontal lines on both the left and right. This piece overlaps an inch or two onto the strip to the right. You can just barely see a bit of the blue plastic tape I am using to keep paste off the piece that it is overlapping.

Now it’s time to make the double-cut. I have placed a strip of polystyrene plastic on the wall under where my splice will take place. This will prevent my razor blade from scoring into the wall surface below. This is important, because an un-intact wall surface may give way when the tension from drying / shrinking wallpaper tugs on it, causing a popped seam.

I found a spot among the vertical lines where I could have the spacing between lines and squares look similar to the natural rhythm of the design. Using a straightedge and new razor blade, I cut vertically through both layers of wallpaper. In the photo, you see the excess paper of the top piece, along with its protective blue plastic, falling away.

Not shown is removal of the excess piece from the strip of paper on the bottom, and also removal of the polystyrene padding strip. The blue tape was also pulled away.

The last shot shows the area over the door after the spliced pieces were smoothed back into place. Perfect!

Nobody would guess that the pattern is a tad out of sequence.

And, yes, all this takes engineering, concentration, and time. There were five sections over the doors and windows, each only 13″ high. I spent more than six hours on just these five sections.

Clever Kill Point – Eliminating a Pattern Mis-Match, Damask Pattern

January 15, 2019

When you hang wallpaper around a room, usually starting in a corner, the pattern on your last strip will never perfectly match up with the pattern where you first started. So we try to hide this in the least conspicuous place – like behind a door.

But in this room, there were no “hidden corners” that would be obscured by a door. Since all four corners were very visible, I wanted them all to have their pattern match perfectly.

So I had to find another place put that “kill point,” – where the last piece meets up with the first piece. I decided to put that over the door, a 20″ high strip. I figured that would be less noticeable than a 7″ length in a visible corner.

Sorry, for some reason, my “before” photo disappeared; it was a shot of the gap over the door where the last strip was coming to meet the first strip.

In the top photo above, I have overlapped the two strips, to see how “off” the pattern match will be. I am preparing to splice these two strips together, and will use some tricks to make that pattern mis-match less noticeable.

Next, I padded the wall with some scrap paper. This means that I placed a width of scrap paper behind these two pieces that will be spliced together. This is to protect the wall from being scored when I make my splice. You don’t want to cut into the wall when doing a splice, because, when the wallpaper dries and pulls tight, it can put tension on the wall, sufficient to cause the layers to delaminate and pull apart, creating a “popped” seam.

Next, I took a sharp, new razor blade and cut through both layers of wallpaper, using the swerving lines in the damask design as a guild – a swerving cut will be less noticeable than a straight like that cuts abruptly through the pattern.

This is tricky, because you want to cut through two layers of wallpaper, but not into or through the third layer that is being used to pad and protect the wall.

Second photo – I screwed up! For some reason, I had trouble cutting through the two layers of wallpaper. I tried twice, but each time I only cut through one layer. So I attempted it one last time, making sure to push really hard on the razor blade.

Well, now the razor blade was ready to do its job … But it was too zealous … This third attempt, the blade cut neatly through both layers of wallpaper, which is good. But it also cut through the third layer of wallpaper I had put behind everything, to protect the wall. And into the wall underneath. In the photo, you can see how the drywall was scored. This is bad.

To prevent the drying / shrinking wallpaper from tugging on those cut edges of drywall, I grabbed some special paper tape I keep in the van, and placed strips over the curved cuts in the drywall. These are very difficult to see, but the paper strips are there, in the third photo.

Then I fit the two strips of wallpaper back together, smoothing them into place over the paper tape. Then I made sure to wipe off any paste residue that was left on the surface.

Now, if those two spliced strips of wallpaper should shrink as they dry and put tension on the wall, the tension will not be on the cuts in the wall, but rather on the strips of paper. The strip of paper tape will disperse the tension over it’s 1″ width, and keep it away from the weakened areas of the cut drywall. This should prevent any delaminating of the drywall, and prevent any popped seams.

In the last photo, we are back to hiding that last seam, the “kill point.” From down below, your eye will never pick out any pattern mis-match. Mission Accomplished!

Mountain Mural for a Mountain Climber

October 6, 2018


This homeowner is a mountain climber, and goes every chance he gets. He wanted to bring a little of his passion into his home, and this rear wall of his closet was the lucky spot.

A lot of the mountains and sky were cut off where the cabinets hit the wall, but you see enough of the photo to feel like you are there!

The mural is by MuralsYourWay.com (who happen to be fellow members of the Wallcovering Installers Association). It was custom-sized to fit the wall (allowing a 2″ “bleed” all around each side). It came on a heavy vinyl material with a canvas backing, and was pretty thick. That made it a little difficult to trim.

There was one seam, and that was double-cut (overlapped 2″ and then spliced). Since the material was so thick, and with the fabric backing having threads that got caught up in the seam, it was somewhat difficult to cut – I used a new single edged razor blade and had to press really hard to get through both layers. I used a thin polystyrene plastic strip to pad and protect the wall under the cut, so the drywall would not be damaged (cut drywall can delaminate and result in a popped seam.

I also used blue plastic tape on the edge of the overlapped piece, to prevent paste from getting on the face of the mural.

The wide strip on the left would have been unwieldy trying to fit around the upper and lower cabinets, and the material was prone to creasing. So, I split the strip in half vertically, so the first half went to just an inch past the cabinets. This was much easier to manipulate, and put less stress (potential damage) on the paper, plus it kept paste off the cabinets. Then I was able to easily position the short piece that went in between the upper and lower cabinets.

This is a new construction home in the Tanglewood area of Houston. I was lucky enough to work all by myself, with no other construction workers in the house. No noise, no distractions = happy.
