Meg Braff Bad Printing Job

November 15, 2022
The homeowner very much loves this simple, tone-on-tone shore bird pattern for her dining room – just the top , above the chair rail / wainscoting. Here I’m plotting where to best situate the pattern on the wall , between the chair rail and ceiling , while keeping the most important pattern elements and motifs intact . (no cutting off birds’ heads at the ceiling , nor at the wainscoting ) I’m also checking the pattern match .
It quickly became evident that the pattern match, as laid out by the factory, was incorrect . Match it at the bottom (by my thumb ), but as you move up , the pattern goes a little out of whack . This is actually not all that bad , and is considered acceptable – the industry standard allows for up to 1/8″ – 3/8″ mis-match .
Hand-trim screen-print materials such as this are particularly notable for pattern mis-matches .
For the record, they’re also known for curling edges , puckering , waffling , and other issues that make them difficult to hang , as well as questionability as to how long they’ll perform on your wall before wanting to resort to that curling at the seams .
More pattern mis-matching .
But the situation got worse . These high-end screen prints often come with an unprinted selvedge edge that has to be trimmed off by hand , with a straightedge (the blue metal thing ), a razor blade – and a steady hand.
If the trim guide marks printed on the material by the company are ” off ,” then you’re supposed to ” trim to the pattern .” This means that you find the design element on the left edge of the paper and then find the corresponding element on the right side, and place your straightedge so that your trim cuts will result in the two edges matching up perfectly. (Or at least within that 1/8″ -3/8″)
At this point, the white lines in the design – let’s call them ‘grapes’ – are abutting my blue straightedge , and should meet up perfectly with the corresponding white lines on the grapes on the opposite side of the subsequent strip of wallpaper.
But, unfortunately, with this material, that didn’t work. If I lined my straightedge up with the pattern design elements , as in the photo above this one, by the time I moved down a few feet , as you can see in this photo , the pattern begins moving away from the straightedge . The white grape outlines do not butt up against my straightedge.
The likely reason is that this material has been printed on the bias . That means that the artisan at the factory got his screens out of whompus , for lack of a better term.
” Trim to the pattern .” OK. So here I’m placing my straightedge at 1/8″ away from the ” hook ” in this design .
Still the same distance from the “hook.” But the white lines are starting to move away from the straightedge.
Here they’ve moved farther off. With this design, from a distance , you could maybe live with the white lines not meeting up perfectly.
But what you couldn’t find acceptable is that the tan area between these white elements would be growing wider diagonally as you move both up and down the wall. Look at the photo. You can see the tan area growing larger .
But it gets worse as it spreads farther … As that tan section grows wider like a “V” or a wedge as you move up or down the wall, it additionally pushes the design motifs at the top of the ceiling or at top of the wainscoting either up or down along the horizontal lines of the ceiling and wainscoting .
So not only do you get a widening tan line between each seam , you also get the birds’ heads moving up or down from where they’re supposed to be positioned below the ceiling or above the wainscoting .
I spent an hour and a half trying different placements and trimming methods . I knew the client loved this pattern and that she was willing to accept reasonable flaws in the pattern match and positioning.
But even given that, I wanted her to have a good looking dining room – not one with uneven spacing between strips, or grossly irregular positioning along the horizontal lines in the room.
I even consulted with several (five!) “high-end” installer buddies of mine. No one had a ” tip ” for making an improperly printed design fall correctly on the wall. In fact, all five of them said it couldn’t be done.
I determined that this material was unhangable.
As mentioned, I tried to find an installer buddy who could make this work and get this client’s dining room done in time for Thanksgiving dinner. But no one wanted to take it on.
I don’t know if the manufacturer will replace the paper or refund the $ spend. Manufacturers are usually keen on saying that “it’s the installer’s fault .” I can say that I’ve had similar issues with Meg Braff papers in the past.
The homeowner really loves this pattern. It’s possible – but not assured – that purchasing the same design but in a different run will yield a better factory printing job.
Just a note that printing defects , curling seams , wrinkling / quilting , and more, are somewhat common with hand-screened wallpapers . And here’s another reason why I’m happiest when clients stick with middle-of-the-road, or slightly upper priced , wallpaper options . Email me and request my Info Pack (or see the link on the right) for more information and brand name recommendations.
Sad to bow out and leave this client with an unpapered room, and no viable solution or direction . But better that than to take on something that I can’t assure will look good. I hope she tells me what she ends up doing and how all this turns out.

Special Paste for Special Paper

July 22, 2020


Most wallpapers can be hung with standard wallpaper pastes. But some papers are more delicate or have special characteristics (silk, vintage, non-woven, prone to curling seams,) and thus call for special pastes.

When certain pastes are used, non-woven wallpapers like this one can display “blushing” or “staining,” which look like wet spots that never dry.

This manufacturer, Rebel Walls, has included a box of paste that is specially formulated to work with non-woven material. It is a powdered potato starch-based paste that is mixed with water on-site, allowed to set up, then mixed again, and then it’s ready to use.

To be honest, I probably wouldn’t use this paste. With the propensity of non-wovens to blush and stain, the less moisture you introduce, the better. So I would opt for a pre-mixed clear paste, such as Roman’s 838 or SureStik 780. But beware – some other types of clear pre-mixed pastes will stain (880, 234) and probably clay pastes will, too.

Humidity in Bathrooms – Not Good for Metal Light Fixtures

June 7, 2019


This is the same bathroom that showed the curling / delaminating wallpaper seams, probably caused by humidity.

This photo is of the base of an over-the-mirror light fixture. See the little dots? I believe these are specs of rust starting to work their way out through the finish. Most likely also caused by humidity.

Keep heat and A/C systems running, limit steamy showers, keep the exhaust fans on, and keep doors open!

Soft Mattress Ticking Stripe in an All-White Bathroom

April 24, 2019


With just paint on the upper walls, this all-white bathroom was simply … too white. The addition of a soft stripe, in the shape of a classic mattress ticking pattern, was just enough to add some warmth and definition to the space.

While I like the pattern, I am not fond of the material, nor the brand. Norwall is one of the lowest-priced manufacturers out there, and … you get what you pay for. This is a solid vinyl wallpaper with a paper backing. The vinyl surface sounds attractive to homeowners, because it is a tad more stain resistant than other papers, and because it repels water.

The bad news is that humidity (such as when someone takes a shower, or splashes water on a seam) tends to find its way behind the seams and into the paper backing. That paper then swells and pushes away from the wall, causing the seams to curl.

Over time, the vinyl top layer can actually separate (delaminate) from the paper backing, leaving curled seams that cannot be reattached.

In addition, the seams are always a little “pouched” when the paper is installed, and never lie completely flat. It’s also common for this material to bubble or blister as it dries … I call it “burping” … or more properly termed off-gassing as the air released by the drying paste tries to find an escape but is trapped by the vinyl surface. So you have to keep going around the room chasing out bubbles. Really small ones usually disappear as paper dries.

Type in key words and use the Search feature here (upper right corner) to read my previous posts about these topics.

This was the first time I’ve encountered a Norwall solid vinyl paper-backed product that was not pre-pasted. Maybe the manufacturer has figured out what made it’s wallpaper so crap…py… er… disappointing. To be honest, the paper I worked with today (which had to have adhesive applied by hand/paint roller) went up with fewer problems than usual. There were still blisters, and still seams that were not as flat as they should have been. But overall, it was better than I expected. This is not the same as being “satisfactory.”

Only time will tell how this product stands up to humidity in a family bathroom.

This is a new-but-classic-looking home in the Woodland Heights neighborhood of Houston. The interior designer is Stacie Cokinos of Cokinos Design.

UPDATE: This paper had only been up for a few months when the homeowner called me to say that some of the seams were curling. As expected, this was due to humidity / moisture…. either splashing water or the housekeeper’s damp rag running along the top of the chair rail. Or possibly humidity from showering.

Either way, some of the seams were starting to curl away from the wall, and were on their way to delaminating. I was able to tack down the curls. But if the paper starts to delaminate (vinyl layer separates from paper backing), there is no cure for that – at least, not anything that looks good.

Whoops – Somebody Painted Over Old Wallpaper – And It’s Peeling Up

February 23, 2018


This wallpaper is in the potty room of a Hollywood bathroom in a newish home in Bellaire (Houston). Instead of stripping off the original wallpaper, someone decided to just paint over it.

It’s not clear if they painted over the inked, vinyl / acrylic – coated surface, or if they peeled off that surface coat and then painted over the remaining paper backing.

Not that it would make a lot of difference, but they probably did not prime or seal the surface, either.

Either way, as you can see, the various layers failed, and the wallpaper seam let go of the underlying surface, resulting in the “popped” seam you see in the photo.

This probably has to do with a lot of factors, including an improperly prepped surface (read above), latex paint adding moisture that could cause the underlying surface to expand and swell, and humidity from the shower and the window allowing moisture to enter the edges of the wallpaper.

Once humidity enters the edges of wallpaper, it can cause the paper to expand and then pull away from the underlying surface. This can result in curled seams.

This is what you see in the photo above.

Wallpaper and YouTube Don’t Mix

December 31, 2017


This West University mother of young children went to YouTube for some primers on how to hang wallpaper, and then, along with hubby, spent a 3-day weekend tackling the powder room redo project. They didn’t do a horrible job (first three photos), but there were some things that must not have been covered on YouTube.

First, and probably most important, the walls should have been primed with a product designed for wallpaper.

Second, seams should be butted, not overlapped.

Third, wallpaper should not be wrapped around the door moldings, but trimmed at the base.

Fourth, I’m not sure what’s going on with the cuts at the baseboard. I think the room had seen a number of redecorating efforts, and that the baseboards took a bit of a beating in the process, leaving a surface that wasn’t smooth and wasn’t willing to hold on to wallpaper.

I stripped off their wallpaper, patched bad spots, sanded the walls, then primed with Gardz, a penetrating sealing primer that bonds together porous surfaces and that is also a good base to hold wallpaper.

The rest of the photos are of the room after I hung the new paper.

This product is a pre-pasted, paper-backed, solid vinyl material. It happens to be one of my least favorite kinds of wallpaper. The homeowner chose it because she has young children and the vinyl is reputed to be more water-resistant and durable than other types of wallpaper. If she had consulted with me before she bought her paper, I would have steered her in another direction.

It’s true that the vinyl surface is resistant to water, and it’s more resistant to stains than a paper-wallpaper. But that doesn’t make the product wonderful.

The main problem is the paper backing. This stuff is not horrible, but it does have a reputation for curling a tad at the seams (do a search on my blog for previous posts). Humidity (such as in a bathroom with showering) can cause increased curling at the seams. Any water that falls on a cut edge of the paper (along backsplashes, seams under hand towels, etc.) can wick into the paper backing and cause it to expand, which will cause the seams to curl.

To reduce the potential for seam curling, I used a special pasting process (rather than following the manufacturer’s instructions). And I ran a bead of caulk along the top of the backsplash (see 4th photo – the caulk will be clear when it’s dry) to prevent splashed water from wicking up under the wallpaper.

My trim cuts along the baseboard looked better than the homeowners’, but I still felt the baseboard was compromised somehow and that wallpaper did not have a good surface to grip ahold of. So I ran a bead of caulk along the top of the baseboards, too.

This wallpaper is by Exclusive Wallcoverings, a British manufacturer. It is a faux grasscloth, and, unlike true grasscloths, it is pretty water- and stain-resistant, and it has a pattern that can be matched. In fact, the close-up photo above shows a seam – and I’ll bet that you can’t find it! The pattern number is FD44143

Next time around, when a mom has concerns about her kids touching or splashing the wallpaper, I would suggest she consider one of the newish non-woven products. Or, better yet, a scrim-backed (woven fabric-backed) solid vinyl product, such as something from the Thibaut brand Texture Resource line, particularly Volume 4. Everything in that book is beautifully textured and realistic, and virtually indestructible. Do a search here to see my previous posts.

Stay Away From Paper-Backed, Solid Vinyl Wallpapers

December 6, 2017

Solid vinyl wallpapers are often marketed as “kitchen and bath” papers, because they are somewhat more washable than other types of wallpaper, and because splashed water will run right off the vinyl (plastic) surface.

However, I find just the opposite with these solid vinyl papers, particularly the pre-pasted, lower-priced ones.

The seams generally never look great to begin with. Then the porous paper backing tends to absorb moisture, such as humidity in a steamy bathroom. When the paper absorbs moisture, it expands, and when it expands, it has nowhere to go but to push away from the wall – causing a curled seam. Often the top vinyl layer even starts to delaminate from the paper backing.

This is not a “loose seam,” and it cannot be “reglued.”

Humidity is a factor, but so is improper wall prep. Usually, when there are curling seams like this, the previous installer neglected to prime the walls, and just hung wallpaper on top of the bare drywall.

In the two photos with paper curling away from the top of the baseboards and from the top of the granite countertops, it is not sticking because the surface beneath it is slick – overspray of gloss paint from the woodwork, caulk used around the top of the backsplash. Again, a primer would have prevented this.

I also like to run a bead of caulk around the top of the backsplash, to prevent splashed water from being wicked up under the cut edge of the wallpaper, which would cause curling.

I have blogged a number of times about curling seams due to crummy paper-backed, pre-pasted solid vinyl wallpapers. Choose some key words and do a Search here to read more.

Homeowner Tackled the Wallpaper Install – So, How’s That Working Out for You?

August 9, 2017

The homeowner tried tackling this wallpaper installation herself, without even consulting so much as a YouTube video. She didn’t do an all-out bad job, and the paper is still stuck to the wall after three years. But there are a number of things that were done incorrectly.

1. Walls were not primed with a wallpaper primer

2. Caulk should have been run around the top of the backsplash

3. Paper was wrapped around the edge of door moldings and not trimmed.

4. Seams were overlapped

5. Overlapped areas were not secured with a “vinyl-over-vinyl” adhesive.

6. Pattern was not matched.

7. And, last but very important – a poor choice of wallpapers.

I am not a fan of paper-backed, solid-vinyl wallpapers, especially the pre-pasted, lower-end products. Do a Search here on various terms, and you will learn a lot about the material and its poor performance. IMO

In the meantime, when I take on this job, I will remove all the old paper, scrub the walls to remove paste residue, fix any dings in the walls, prime with an appropriate primer, hang the paper properly, by matching the pattern, butting the seams, and trimming correctly along baseboards and door moldings, etc., and, when finished, I will run clear caulk along the top of the vanity and other key areas, then give the family my “lecture” about leaving the door open and using the exhaust fan and avoiding long steamy showers.

Brightly Nautical Wallpaper in a Master Bathroom

I didn’t get pictures of the original wallpaper, but it was a pre-pasted, paper-backed solid vinyl (my least favorite kind) and had been poorly installed on un-primed bare drywall. Over the 12 years it was up, humidity from the bathroom had penetrated the seams and caused the paper to curl.

This paper (not vinyl) wallpaper, hung over properly primed walls, will cling tightly to the wall and perform well for many years to come. Plus, it’s bright and pretty and adds a lot of life to the room.

One shot shows the oceanic paper in the main room, looking into the potty / water closet, which has been papered in a coordinating yellow striped pattern. I really like using two papers this way. See tomorrow’s post for pics of the potty room.

This home is in West University Place (Houston). The wallpaper pattern is #839-T-6701 by Thibaut Designs, and was bought at below retail price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.

Spring Time in a Powder Room

I forgot my camera yesterday, the day I stripped off the old paper and prepped the walls, so I cannot show you the 15 year-old wallpaper with its curling seams, due to 1.) being an inexpensive paper-backed solid vinyl wallpaper (my least favorite kind – do a Search here), and 2.) the previous installer did not prime the walls but instead hung the wallpaper directly on the new home’s bare Sheetrock, and 3.) age, heat, and humidity. The pattern, however, was not too dissimilar to this one, being a sort of “impressionistic painting” design in the same blue, pink, yellow, and green color scheme.

Anyway, the new powder room looks fantastic. The colors are similar to what the homeowner had before, but this wallpaper should hold up much better. The material is paper (not vinyl), and will hug the wall tightly. I removed every scrap of old paper and sealed the walls with a penetrating sealer named Gardz, and then primed with a wallpaper-specific primer called Roman’s Ultra Prime Pro 977.

On top of this good foundation, the new wallpaper is a pre-pasted, raised-ink paper by Thibaut, and is one of my favorite products to work with, and I also love it’s dependable performance down the road. The pattern is #6936, and is very similar to their “Augustine” hummingbird design (Do a Search here). I love the barely-discernible texture of these raised-ink papers. A unique printing process results in this effect.
