This is What You Get When You Ask the Painters to Wrap 1/4″ of Paint onto the Wall to Be Papered

March 22, 2022
A quarter inch of new pink paint from the sidewalls underlapping onto the wall where I will be hanging a mural will ensure that none of the original tan wall paint will peek out of the corner. All it takes is 1/4″ , which is what I asked the painters to provide.
As you can see, someone has a little problem with his measurements and math. This swath is more like 2″-4″.
Not a biggie. It’s a matt finish paint, and won’t be difficult for either my smoothing compound or wallpaper paste to adhere to.
My first task in this room is to skim-float the wall to smooth over the orange peel texture. That task took a lot longer than hanging the wallpaper!

The Big Easy On The Walls

March 5, 2022
West wall smoothed, primed, and ready for wallpaper.
The homeowner used to live in New Orleans, and she tells me that signs like this are very common in local convenience stores and neighborhood dives. Transplanted to Houston, these signs are very dear to her heart as a reminder of her roots – and the funky lifestyle in the Big Easy.
She wanted the signs recreated somehow to cover the walls in their newly-renovated powder room in the Houston Heights. I suggested she contact rebelwalls.com , who custom made the paper and sized it specifically to fit each wall in the room individually. I measured and made drawings, and a designer named Simon at RebelWalls laid it all out.
North wall before. This is the wall with the toilet and sink.
There were a couple of glitches, the first being that the strips were printed about 10″ longer than I requested. No biggie – I’d rather have too much paper than come up short.
But the main glitch being that I had asked for this “sign” to be centered over the toilet, which meant that the center of the sign (I used the middle fleur-de-lis) would land at 17.5″ from the wall to the left. But somehow it got printed to where the left edge of the pattern was 17.5″ from the wall … That left a whole lot of white space between the wall and the design, and also pushed the words too close to the mirror, which will hang over the sink to the right.
After careful measuring, calculating, and testing, I determined that if I used my straightedge and razor blade to take off a 12″ wide slice from the left side, the “sign” would move to the left such that its center would fall over the mid-point of the toilet.
VoilĂ ! As you see in the photo, now the words are nicely balanced on this section of wall, and will not crowd the mirror which will be hung to the right.
The rest of the wallpaper moving to the right is unprinted, so as to leave a blank slate for the mirror to hang on. Here you see that wall, and also the wall to its right. This east wall has the same sign, but in a smaller scale, sized to fit the narrower wall. It’s also placed at a different height
Graphic designer Simon used my drawings and measurements to get the words nicely centered on this wall. The area above the door to the right (not visible) is left blank.
Here is the west wall (on the right) abutting the south / window wall.
The bull-nosed / rounded edges / corners such as you see around the window are really a pain with wallpaper, especially when they go both around the sides and the top, and can lead to some impossibilities. Too complicated to get into here. But I was pleased with the way this worked out. And the placement of the pleated shades toward the front of the opening helped a lot, too.
One interesting thing to note is that the thickness of this non-woven wallcovering (along with the joint compound I used to smooth the textured wall) is enough that it narrows the space inside the window just a tad,,, and that makes it a bit tight for the shades to fit back in,,, and that opens the potential for abrading the wallpaper as the shade is raised and lowered over time.
Another point … even though the widths of the wall spaces to be covered were different, we requested that the size of the font on the “sign” lettering be the same on the west wall and the north / mirror wall, and ditto for the window wall and the door wall.
I also made sure that the “signs” started at the same distance from the ceiling. This then ensured that each “sign” would land at the same distance from the tile below it.
Synchronizing the size of the fonts as well as the spacing between ceiling and tile helps immensely to lend a feeling of unity and order to this room.
I spent a full 2 1/2 hours plotting, measuring, testing mock-ups, and going back to the drawing board, before I ever cut any paper.
Prior to that, there were two visits to the home to get measurements and kick around options with the homeowner. In addition, she spent countless communications with the manufacturer and with our specific designer.
All this futzing is important, because, with murals, there is no second chance. There’s only one of each panel, and if one gets screwed up, there are no more to pull off the bolt, like you’d have with regular rolled goods.
RebelWalls is the manufacturer. I’ve had lots of great installs with this company.
What was inside our box, including Simon’s dimensions and lay-out.
Basic installation instructions. Ours was a bit – a whole lot – more complicated, because it covered not one but four walls. In our case, it worked best to have each wall be a separate mural, so to speak.
RebelWalls includes free wallpaper paste. I prefer to use my own pre-mixed vinyl adhesive, which is SureStik Dynomite 780. Recently bought by Roman, so the name has changed to just 780.
Certain pastes have been known to ” stain ” non-woven wallpapers (areas look wet but never dry out). I think that a high moisture content in the paste has a lot to do with this. So I’m hesitant to use a powdered paste that needs to be mixed with water.
I’ll squirrel away that RebelWalls powdered paste for another, better suited job. For this home’s install, I’m sticking with my tried and true 780.
A coupla more notes.
One, this project was a study in vision, desire, anticipation, and patience. The homeowner first contacted me in July 2021. It took nearly eight months to come to fruition. Granted, they had a whole kitchen remodel in the middle, which also included an update to this powder room. But just speaking for the wallpaper, there were several site visits, many emails, and then innumerable communications with the design team at RW.
In fact, since I’ve hung lots of RebelWalls and am familiar with their process, I thought I could lay out the design. But this project of separate “sign” motifs for each wall section was taxing my skill set. Finally I laid down my pencil and paper and said, “Stop doing what you yell at your clients for doing, which is trying to do something you don’t have expertise in! RebelWalls has designers who are trained to figure all this out. So let THEM do the math and placement and calculating and layout.” So we turned it over to them, and within a short time they had it all worked out perfectly (except for those few glitches I mentioned). Their customer service was amazing.
All this was crucial to ensuring that mural pieces fit the wall perfectly and that the final product looks stunning.
I also want to mention that the RebelWalls quality is excellent. It’s a non-woven material which has many advantages (too numerous to go into here, but you can Search). The seams melt together like butter and are invisible – even on areas with all that bare white space with no pattern. On a simple accent wall, you can paste-the-wall to hang it. In this (and most) cases, I pasted-the-material, which gives more flexibility and also ensures that paste gets into hard-to-reach areas – like behind a toilet.
In addition, the non-woven material is designed to strip off the wall easily and in one piece when you redecorate.
The company offers scores of patterns, from cute to sophisticated, and, as we did this time around, can make custom creations.
Super customer service, too.

Koncentration Killer

April 23, 2021

I HATE noise. But this is probably the WORST type of noise EVER.

It’s uncanny how often these guys show up at the homes where I’m hanging wallpaper.

The racket and reverberation penetrate the walls and hijack my brain.

All this ruckus bollixes up concentration, focus, math, engineering … It leaves me with a headache, nausea, double vision,,,

“I Hate Leaf Blowers” – Google it.

Feathery Stripe in Memorial Area Entry Hall

February 1, 2020


I admit … When the homeowner first emailed her selection to me, I wasn’t crazy about the design. But once it started covering the first walls of the home’s entry – boy did I start to see her vision. It is stunning. And it’s one of those patterns that looks even better in person.

It’s a sort of a wide, scratchy stripe. The homeowner says it reminds her of feathers.

I spent a lot of time with math and engineering, and in the end was able to balance / center this pattern not just on the first wall with the front door (2nd photo), but on two other walls with doors, as well as this widest wall (1st photo). And I eliminated a noticeable kill point (no photo).

This wallpaper pattern “Plume” is by Cole & Son, and is on a non-woven backing. This means that it does not expand when wet with paste, plus there is no booking time, so you can paste it and hang right away – or you can paste the wall. I’m glad I pasted the material, because walls in this room were pretty wonky, and softening the paper by pasting it made it easier to manipulate it to match up with the crooked walls.

Non-wovens are also designed to strip off the wall easily, cleanly and in one piece when it’s time to redecorate.

I did encounter a few minor printing defects. But we had enough extra paper to work around them.

Balancing Grasscloth Panels

January 18, 2020


Because grasscloth does not have a pattern that can be matched, the seams are always visible. And, due to the characteristics of natural materials, the strips will have color variations within themselves. This means that you will distinctly see each individual panel on the wall.

Because each panel is noticeable, walls usually look better if each panel is the same width. In other words, on a wall 14′ wide, it looks better to have five strips that are each 33.5″ wide, rather than four strips that are 3′ wide and one that is 2.’

In addition, grasscloth invariably comes with edges that have been abraded during shipping. On top of that, it’s common to have color issues at the edges – either a light band, or a dark band, or irregular bands of shading along the edges.

For that reason, many paperhangers trim the edges off both sides of each strip of grasscloth. This allows the installer to trim the width to fit the wall’s dimensions, it gets rid of most of the damage caused by shipping and handling, and it reduces the shading that the manufacturer’s dye process may have left along the edges.

If you study the photo closely, you will see that all these panels are the same width.

And, while some jagged color variations do appear along some of the edges, it is not pronounced, as the darkest areas have been trimmed off.

There is still a color difference between the three strips on the right and the four strips on the left – but that is just the nature of grasscloth and its manufacturing process

As you can imagine, all this measuring and plotting and trimming takes extra time. If you’re like me and like math and geometry and logistics, hanging grasscloth can be a whole lot of fun!
