Different Runs – Different Materials

February 25, 2023
Due to a mix-up in terminology, the homeowner originally received just four single rolls (two double roll bolts ) of wallpaper .  They needed eight total single rolls (four doubles ), so two more double roll bolts were ordered.  Being unable to get the same run number , we anticipated a slight difference in shade .  But didn’t expect that the two new bolts would be thinner than the two original bolts . 
What the heck is up?! 
The selection book says this is a non-woven product, and a paste the wall installation method .  Yet the label on both the original and the new rolls says to paste the paper.  Even more puzzling, the instruction sheet included inside the rolls says that it’s  non-woven material , and to paste the wall. 
It’s important for the installer to know what material he’s working with, so I needed to know if this was PTW or PTP .  Usually, non-woven paste the wall are thick and hard to tear , due to their 20% polyester content .  The fat roll felt and acted like a non-woven .  But the thinner roll was thin and crispy and easy to tear.  I sure thought it was a paper material , which would require a different installation technique .  In recent months, I’ve had this same manufacturer send several rolls of the a particular pattern , but some were non-woven, and some were paper.  So I thought we might be experiencing this again.  It’s important to know what you’re working with, because different materials require different installation techniques.  If a DIY ‘er follows the instructions to paste the wall , but it’s actually a paste the paper material, he’s going to encounter a whole lotta mess – and ruined paper . 
Here I used my 24” wide straightedge to tear off a strip of wallpaper from the roll of thin material.  This answered my question.  See the little fibers ?  Those are indicative of non-woven papers, and their polyester content .  Once I saw this, I was certain that it was, indeed, a non-woven material / paste the wall . 
So this material was easier to hang than traditional papers, because no need to paste , book , and let sit for a few minutes.  There are other pluses, too, to NW papers, and most of us professionals like hanging them.  But I wasn’t 100% pleased with the thin version of this non-woven material.  For one thing, its stiff, crispness made it difficult to manipulate, and prone to crease . Also, notice the splotchiness of the paper.  This showed up on the dry paper, right off the roll.
But paper that has been pasted and hung on the wall showed even more splotches .  This is scary, because there is a issue called blushing or staining , where the paper looks like it’s wet , but never dries out.  Do a Search here to learn more.   This happens mostly with non-woven papers , and is tied to certain types of paste .  Which is why I don’t use those pastes!  So curious as to what is causing this slight discoloration.
I believe the spots were just due to moisture .  As I worked my way across the wall and time went on, the paper I had hung first had a chance to air out and dry.  The blotches disappeared . 
 
I’m curious as to why the difference in material.  Maybe the manufacturer was using different factories?  In different countries? Or supply chain issues / material shortages meant that their usual substrate and inks were not available .  Or just trying to cut costs?  Saving money isn’t a bad thing.  But it is, if it cuts down on the product’s quality. 

Slight Problems With Katie Kime Wallpaper

January 11, 2023
There were eight double roll bolts of this wallpaper , to cover a large powder room in Houston.
Four were rolled so the pattern came off the top of the roll, and four were rolled the opposite way, with the bottom coming off first. This Katie Kime brand is custom-printed , so you can assume that all these rolls are from the same run , or batch . But maybe not - why are some forward and some backward ? Possibly the company substituted some returned goods, or some old stock they had sitting around the warehouse, for half of this order.
I didn't want to risk putting strips of slightly different shades on the same wall. So I had to carefully plot the room so I used the "forward" rolls on some walls, and the "backward" rolls on the others. This does eat up additional paper , so good thing I always have the homeowner purchase a little extra.
Also note the crease in the roll on the right. There were a few other creases in other rolls.

I have no idea what happened to the font in the section above, nor do I know how to get it back to the original. All I know is that I HATE this “New Editor” that WordPress foisted on us a few years ago. Perfectly HORRIBLE. And their Customer Service doesn’t care. Anyway … moving on …
Note the horizontal smudge next to the top of the capitol. Since this Austin Toile pattern has a 25″ pattern repeat, discarding this piece ate up minimum of 2′ of material (x 24″ width = 4 square feet) and potentially more, to get the correct pattern match.
Usually this brand prints on a nice non-woven / paste the wall substrate. But, like other manufacturers, Katie Kime has had supply issues obtaining raw materials . During the height of the Pandemic , they resorted to printing on some positively awful stuff. Extremely heavy , thick , un- pliable , stretched to the extent that the pattern wouldn’t match properly, and more. One was completely un-hangable and had to be sent back. I can’t find all my posts re those challenges, but here is one:
https://wallpaperlady.wordpress.com/2021/07/21/katie-kime-tough-install-today-draft-messed-up-delete/
But they’ve since gone back to printing on their usual stock, and I’ve not had problems lately. So when I first picked up this box of 8 double roll bolts, I was surprised at the weight of it. Also the paper had a shiny surface and was obviously composed of vinyl . I couldn’t tell if the substrate was non-woven or paper . I feared they had gone back to printing on that bad material , or perhaps were using up what they had in the back of the warehouse .
There were no instructions included, nor any information at all – not even a brand name! Although I could find instructions on-line, you can’t be sure these are current and applicable to the rolls in the box. KK has amazingly good customer service , and you can usually get intelligent answers via phone or on-line chat … but my call to them went to voice mail , and then we got disconnected, so I gave up.
After hanging the first few strips, I figured out that this was a flexible vinyl on a non-woven substrate, so that part was good. However, the thickness of the material interfered with getting good, tight, flat seams , as you can see somewhat in the photo. The seams aren’t horrible, but a better non-woven without the vinyl usually produces almost invisible seams.
The surface was shinier than usual. Shiny tends to show every imperfection in the wall underneath. Here the thickness was a bit of a help, as it helped cushion any slight dips or pimples on the wall.
There was also an odd orange discoloration about 1.5″ long on the edge of one strip. Very faint, but I could see it, and sometimes these things end up catching your eye. I also worry that it might be some substance that will bleed into the paper and cause a larger stain over time. Of course, this popped up after I had hung a very difficult piece in a tight spot, and then hung the subsequent strip. In other words – no way was I taking it off the wall and re-doing. I cut out a design motif and pasted it over the area.
Another thing I was unhappy with has happened a number of times with KK paper. The pattern will match perfectly at the top of the wall, but begin to slide up or down, creating a mis-match , as you move down the wall. I think that a lot of it has to do with the vinyl material, because it’s stretchy. The weight of the paste and the vinyl will cause the bottom section of the strip to sag. This simply doesn’t make sense, though, because, if the paper is going to absorb moisture from the paste and expand (which many papers do), each strip should do so at the same rate, right? But not.
I finally deduced, correctly or not, that the pattern gets distorted as it’s wound into a roll. So my theory is that if you take your 10′ strips from the same position in each roll, the pattern should match. In other words, take a 10′ strip from the top of roll #1. Take your next strip from a brand new roll #2. Third strip from roll #3. Obviously, this leaves a whole lot of unused paper. For shorter areas like over doors, where it’s harder to see, and where you can fudge the pattern a bit, I used the paper from the insides of the rolls, again, roll #1 next to roll #2, etc. But this doesn’t work on every instance, so you’re gonna be stuck with many areas where the pattern doesn’t match perfectly across the seams. The solution is to match the pattern at eye-level , and then allow it to go off as it moves toward the ceiling and floor.
There were other issues with this paper that were disappointing to me. But not overwhelmingly awful. Most homeowners would not notice. But I sure hope that this was a one-time issue, and Katie Kime will go back to its former good-quality, non-woven material.

Tile Comes In Runs, Too

December 24, 2022
See the difference in color between the tile square in the bottom left and the others?
Look closely, and you’ll see that the tile above it is also slightly darker than the tile to its right.
These tiles obviously came from a different run , or batch . Just like wallpaper , tiles that are made at the same time with one batch of pigments will be ever so slightly different in shade from tiles made from another batch or run. That’s why it’s important to check the run number on the label , so only tiles (or wallpaper !) from the same run are used next to one another.

More Disappointments in York Wallpaper

December 16, 2022

Large creases spanning the width of the bolt were found in several places – luckily just in one bolt / double roll of the wallpaper .
Most non-woven wallpapers are strong and durable . But some versions, such as this one, have a surface that creases easily. You have to be careful while handling it during installation . Here we see that even the manufacturer has problems with it, because these creases were deep inside the roll and caused by the factory.
Also, very common with York – printing defects . Here I have laid two different bolts of paper on top of each other, to compare the printing. Look at the green leaves on the left side. Note that the ones on the far left are closer to the edge of the wallpaper . But the ones to the right are a bit further back from the edge .
Curious, because both bolts are from the same Run (do a Search here to read more about Runs). Obviously, the factory’s trimmers / cutters or the printer mechanism have gone off track and skewed the trimming / printing .
so these two rolls cannot be used next to each other, because the pattern doesn’t match correctly , as you see here. (Also note the creases on the right.)
Actually, with this busy pattern, we could have gotten away with this slight pattern mis-match . (With the homeowner ‘s consent, that is.)
But we were lucky that I had suggested she purchase a little extra paper . So we had three rolls of the version on the left, and two rolls of the one on the right. I was able to plan out the powder room so that I used the three rolls on three walls, and then kept the last long wall for the two bolts of paper on the right.
Note that sending this material back was not a viable option. These issues are pretty common with York products, so we’d likely just be getting the same thing all over again. Disappointing, because, until just a few years ago, York was a very dependable , quality brand .
The pattern is called Wildwood and is by Rifle Paper , which is made by York .

Disappointments in York Wallpaper Pt II

December 16, 2022

OK, because this CRAPPY “New Editor” that Word Press FORCED on us a couple of years ago – which is EXTREMELY difficult to use, BTW, and the Big Wigs at Word Press don’t give a flip, despite my many comments to them … Anyway, it decided to eat / delete the post I just spent 30 minutes typing up, so I’m going to have to write it all over again and try to remember all the points I had made. PISSES ME OFF, this DAMNED WORDPRESS NEW EDITOR.
End of rant. But STILL FARKIN’ ANGRY!!!
Anyway, you’re looking at images of the same pattern motif , from the same Run number (do a Search here to learn more about runs ), but two different rolls / bolts . Look at where my pencil is pointing in the top example – at the green leaf to the left of the blue flower . You’ll see the light green color shadowing , or following the dark green .
Now look at the same motif on the example below it. Here both green colors are together . Why? What’s happened is that the printing presses at the factory have gotten out of register .
The machines print each color separately , layering them on top of each other . For example, brown first, then light green, then dark green, then blue, etc. Each turn of the printing rollers has to be perfectly synced with the previous, so that the colors and motifs line up correctly .
Here, obviously, something got out of whack .
Looking at this, the mis-alignment is not a big deal. It’s a loose , cheerful pattern , and it doesn’t really matter if the colors aren’t lined up perfectly. In fact, I think it makes the pattern more fun.
The problem comes when trying to match strips from one roll up to another, because the design won’t match perfectly at the seams . That does matter IMO . See my other post tonight .
The pattern is called Wildwood and is by Rifle Paper , which is made by York .

Conflicting Information On Label

December 13, 2022
First, note that this wallpaper came in two different runs . This is bad, because each run of a printing job will be a slightly different shade from other runs. This color difference shows up on the wall and looks bad. Do a Search here to see previous posts about this.
Next, note that one label says the material is ” paste the wall ” and the other says ” paste the paper .” This is unusual, because usually Rifle Paper is always paste-the-wall – another name for a non-woven material . So why does one say it’s paste-the-paper ?
Turns out that both of these runs – and all of the wallpaper I had for this job – were paste the paper. This was totally unexpected, especially since the label as well as the specs I had scouted out on line ahead of time said paste the wall .
As far as install techniques, these two methods are completely different animals. Paste-the-paper takes a lot more time, and also is less durable if exposed to water or stains
Not a biggie for me, because I’m familiar with installation techniques of both types. But if a homeowner was trying to DIY his room and was expecting an easy paste-the-wall , he would be in for a much more difficult go-round with the paste-the-paper .

Two Runs – Bad News

December 4, 2022
Always check the Run number before starting your project. Also called Batch or Dye Lot. Wallpaper that is printed at the same time will marked with a Run number. The next time the factory mixes up a pot of ink and prints wallpaper, it’s likely that there will be a slight shade difference between the two batches. If strips from these two different runs are placed next to each other on the wall, you will see a slight striped effect, a difference in color or depth between the two strips. It may be minor, but it’s noticeable and unpleasant.
You can use two different runs in the same room – but not on the same wall. You can “break” the run in a corner, and use one run on one wall and the other run on the other wall. You won’t notice the color difference this way. But it does eat up additional paper.
To avoid ending up with two different runs, first of all, always buy from a reputable company dedicated to selling wallpaper – not an outfit that also sells boots, hubcaps, cold medicine, and whatnot. Second, check the Run number as soon as you receive your material. That way you’ll have time to return it or otherwise resolve the issue, before install day.

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.

Printing Error – Some Thick, Some Thin

September 20, 2022
See the difference between the motifs on these two different strips of wallpaper ?
The ones on the top are crisper and more distinct , with more space between the black lines. The motifs on the bottom have heavier black lines and appear a bit smudged .
Not a huge difference , but on the wall , especially from a distance , your eye would catch this.
Interestingly enough, all these rolls were from the same batch / run number (all printed at the same time with the same ink and printing press ). In fact, one roll started out “normal” and progressively got darker .
It probably would have looked OK to use this darker paper, especially since this was a powder room and you couldn’t step back far enough to see a number of strips next to each other.
But we had enough wallpaper that I could put these aside and use fresh strips with crisp ink to finish the room.
A good reason to always buy a little extra wallpaper !
The pattern is Les Touches and is by Brunschwig & Fils .

Disappointing Defects in Schumacher Sisal Wallpaper

May 12, 2022
The homeowners ordered the brown colorway. So why did they send us both brown and blue??
Look closely and you’ll see that both the blue and the black lines are different thicknesses on each of these three bolts.
Close-up showing different widths of ink.
Even before I unrolled any paper, my suspicions were aroused by this … This cut was made by a hand-held scissors, not a factory machine. That tells me that perhaps an installer sliced off a few feet and then returned the paper, for whatever reason. Now I have no idea how many feet are on this bolt, what run number it is, or why the material was returned.
In addition, the five double rolls of sisal ( grasscloth ) material had no labels, no marks, no run numbers, or other typical information.

Feather Bloom is a very popular wallpaper pattern by high-end manufacturer Schumacher. This family paid several thousand dollars just for the material to cover one accent wall in their home office. Such a disappointment that I could not get their room papered today.

Schumacher is not among my favorite brands, and this is a good example of why. LOTS of printing defects, just about every time I work with it.

But this takes it to a whole new level, because obviously there was no quality control at the factory, no oversight to ensure all rolls were from the same run, nor even the same colorway.

Folks, stay away from Schumacher! As I like to say, for every high-end brand making a cool pattern in a material that’s expensive and difficult to work with, there is someone else making a knock-off that is lower priced and better quality.
