Printing Defects – Serena & Lily Wallpaper

March 6, 2021

Obviously, the factory’s printer or its trimming rollers got off-kilter, creating this pattern mis-match at the seams.

It might have been possible to use a straightedge and razor blade to trim off 1/16″ from one edge. But since the mis-match ran off at a diagonal and was inconsistent throughout the bolt, that would have been extremely difficult and time consuming.

We sent the paper back, and requested new paper from a different run. When the paper arrives, I will visit the clients’ home before the install date to check the paper to be sure the pattern matches correctly.

What a disappointment! The walls are all prepped, the homeowners have dismantled the powder room, and were anticipating a beautiful, fresh new look by the weekend. 😦

S&L is one of my favorite companies, so this is doesn’t make me happy. But it appears that the company is quick to rectify problems with minimal hassle. New paper, from a different run, is already on its way!

ADENDUM: The new paper – from a different run – did arrive. I checked it, and it also had the same printing defects, although not as severe. Very disappointing. Interestingly enough, I have another client using this same pattern but in a different color just yesterday (March 17th). Her paper had NONE of these defects. It’s hard to understand what the colorway has to do with printing problems… But I guess that is a factory issue. See my post of March 20, 2021 to see how this finally turned out.

Repairing Damage from Remodeling

March 5, 2021

I hung this paper in a little boy’s bedroom about two years ago. Now a new baby is coming, so Son #1 is moving from the nursery to his “Big Boy’s Room” next door. In the process of the shuffle, the parents had the connecting Hollywood bathroom updated, and this involved moving a door – which meant messing up the wallpaper.

As you can see in the top photo, instead of taking the time and effort to remove the wallpaper, the workmen put their patching compound right on top of it. I don’t like hanging paper on top of paper, for many reasons. There are adhesion issues. And also, for one thing, it’s not good to have seams fall on top of seams. For another, because the new paper is somewhat thick, you would have a visible ridge from top to bottom along the edge of the new strip.

So I took a razor knife and cut roughly around the workmens’ patch. Then I stripped off the paper around it, up to the edge of the adjoining strip. I did this on both sides of the corner.

This wallpaper is of a non-woven material, and is designed to strip off the wall easily and in one piece when it’s time to redecorate. I was pretty disappointed that that turned out to not be the case.

On the other hand, I was happy that it didn’t. Stripping paper that way puts a lot of stress on the wall surface, and you can end up with delamination (coming apart) of various layers under the paper (primer, skim-float, paint, drywall).

So I used a more labor-intensive, but lower-impact method. Click my page to the right for more info on the process. I first stripped off the top, inked layer of paper. That left the white backing still adhering to the wall. I used a sponge to apply plenty of water to this backing. The idea is to reactivate the paste that is holding it to the wall. Once that paste was wet enough, the backing pulled off the all cleanly and easily.

I was really pleased that my primer from the original install held up perfectly under all this soaking and tugging. I had worried that it might “rewet” and pull away from the wall, which had been my experience with it before. I had used Gardz, a penetrating product designed to seal torn drywall. It’s also good at sealing new skim-coated walls. And wallpaper sticks to it nicely, so all the better!

One photo shows you the stripped off area next to the edge of the remaining strip. You can see the thickness of this existing strip. The new wallpaper will butt up against this, and there will be no ridge because the thicknesses of both strips are the same.

Another photo shows my stripped-off area next to the contractor’s patched area. There is a difference in height between the newly revealed wall and the patched area – and that will show as a ridge or bump under the new wallpaper.

To eliminate that difference in height, I skim-floated over the area. In one photo, you can see the wet (grey) smoothing compound. I set up a strong floor fan to assist in drying. My heat gun also came in handy.

Once it was dry, I sanded it smooth. Now you don’t see any transition between the newly exposed wall and slightly higher patched area. I applied Gardz to the all the newly patched areas. Set up the fan again. And once it was dry, I put up the replacement paper.

It’s a good thing the family had paper left over from the original install. If they had had to purchase new paper, it could have come from a new Run (slight difference in color shade), and that would have meant stripping off and replacing three walls.

We had barely enough paper. The corner was out of plumb by as much as 1/2″ from floor to wainscoting, on each side of the corner. That adds up to an inch out of whack. That one inch meant we needed a whole new strip of wallpaper, to get the paper on the wall to the left to match up with that on the wall to the right.

Long story short, the whole thing turned out great. There is a bit of a mis-match in that corner, but it’s not very noticeable at all.

The wallpaper is by the Scandinavian company Boras Tapeter.

The home is in the West University neighborhood of Houston.

Printing Defect – Shading Issue

Look at the seam, which runs down the center of the page. It is clear that the right side of these strips of wallpaper is darker than the left side.

Unfortunately, this homeowner’s paper is not going up today. And she will have to wait for the company to use up its current stock, and then make a new production run. (Do a Search here on “run” to learn more.)

And then we have to hope that the new run does not have the same defect. Once the paper arrives, I will run by the store and check it, before the client picks it up.

This has to be a fluke, because York, and their SureStrip line, is one of my favorite brands.

Step 1 – Checking Run Numbers

March 28, 2020


Before you start any wallpaper project, it is important to check the Run Numbers (Batch Numbers / Dye Lot).

This means that all the bolts / rolls have been printed at the same time, and are of the same shade.

Bolts printed at different times (different Run Numbers) will be of a very slightly different shade.

They canNOT be placed next to each other on the same wall, because you will notice a subtle-but-disagreeable difference in color between the strips of paper.

So make sure that all your bolts of paper are from the same Run Number.

Note that many on-line vendors are clueless about run numbers, so this is an important thing to check, if you buy low-priced papers on-line.

All the Same Run, Please

February 7, 2020


This homeowner measured her walls and ordered paper before I came by for a consultation. As often happens, she ordered too little paper.

When the additional bolts arrived, unfortunately, they were a different run.

Run number refers to all the bolts that were printed from the same batch or dye lot of ink. The next time the manufacturer prints a run of this wallpaper pattern, the inks will be ever so sightly a different shade.

You cannot place strips of wallpaper from different runs next to one another on the same wall, because you will see the color differences for the entire length of each strip.

You can, however, use different runs on different walls, because your eye won’t notice if the run is “broken” in a corner. This method does require the use of additional paper, though, in order to match the pattern.

In this case, we had enough extra paper. I was able to keep one run on the west and south walls, and then use the other run on the north and east walls.

Grasscloth in Heights Master Bedroom

January 17, 2020


This is the 1st floor master bedroom of a nicely-remodeled-but-still-retains-many-original-details-and-all-its-original-charm 1920 bungalow in the Heights neighborhood of Houston.

The textured walls started out dark green. I skim-floated and sanded them smooth. The new wallpaper is a brown grasscloth with a faint greenish tinge, and it has a nubby texture with a lot of knots (more pics tomorrow!)

The homeowner ordered her paper before I measured the room, and I told her to get two additional double roll bolts. In the 4th photo, I am checking labels to be sure we have all the same run / dye batch; we lucked out and the new bolts were the same run as the original lot.

In the 5th photo, I have cut strips for a wall, and have them lined up and ready to paste and trim. In the background, you can see how I place bolts against each wall, as a way of keeping track of how many strips I need and which bolts I will take them from.

Because there are shading / paneling issues with grasscloth (do a Search here on those terms), it’s important to not mix strips from different bolts. That way, if there are slight color differences between bolts (as there usually are) these differences will be minimized. Still, as you see in the third photo, the three strips on the right came from one bolt, and the strips on the left came from another bolt – and there is a noticeable difference in shade. This is not a defect – it’s simply the nature of grasscloth – a product made from natural materials.

This one long wall used seven strips from three bolts, so a color difference could be expected. On the other, narrower, walls, all the strips came from the same bolt, so the color differences were minimized. When I had to use different bolts on the same wall, I was able to place the “break” over a door or window, with only 1′ of color difference. That’s a lot less noticeable than the 8′ you see on the long wall in the photo.

This wallpaper was bought through Sherwin Williams. There is no brand name on the label.

More photos tomorrow!

Same Run? Different Color?

July 18, 2019


Top photo. Look carefully. You are looking at the start of a printing run on two separate bolts of paper. On the bolt to the left, the color looks pretty uniform.

But on the bolt to the right, you can see a horizontal line where the background has been colored. It’s faint, so look closely. In addition, you can definitely see that the paper on the right is darker than the paper on the left.

If there were more fish present, you would also see that on the right, the greys are a little darker and the reds are a little stronger. There are also more brown speckles in the background of the grasscloth on the right.

What happened was, too little paper was ordered (a simple mix-up between rolls and yards), and so more had to be ordered, and then custom-printed.

The interior designer stressed to the manufacturer that the new paper had to be the same run number (all bolts printed at the same time out of the same batch of ink). The manufacturer’s reply was that their precision printing and ink-mixing was such that there would be virtually no difference in color between what we had already, and what they would print fresh and send to us.

As you can see, that is not the case. Although these differences are minor, if strips from these two bolts were placed next to one another on the wall, the color difference would be pretty noticeable.

So, accommodating for this color difference, we lost about three yards of (expensive) wallpaper.

Need a Little Reading Material in the Bathroom? ??

November 2, 2018


What fun wallpaper! This is very similar to grasscloth. But, instead of using natural grasses and reeds, this material is made of strips cut from magazine pages, rolled and folded into long narrow strips, and then sewed onto a paper backing. In some of the columns, you can actually read the words!

There is a similar product made from old newspapers – appropriately named “Yesterday’s News.”

I hung this in a powder room in a new, contemporary home in the Rice Military neighborhood of Houston. The homeowner, Cristin Wells, is an interior designer http://www.wellsdesignedhome.com/ who recently moved here from Chicago (not far from my hometown of St. Louis!), and brings her sophisticated playfulness here to the Bayou City.

This product is similar to grasscloth in that the seams are very visible. So I engineered the room to have seams fall evenly spaced on each wall, which we call balancing, and which gives a pleasing effect.

In addition, the material can be shaded, or paneled, which means there can be a noticeable color difference between strips, even if they come off the same bolt. In the third photo, you see how I have rolled the paper out on the floor, to check for shading / paneling, so the homeowner will be aware of this issue, and so I can plot how and where to use the various strips.

Indeed, before consulting with me, the homeowner initially purchased two bolts of paper; when I measured the space I told her that she needed five more. The additional bolts arrived in a different run. Run and batch and dye lot numbers are important – all bolts from the same run or batch were printed at the same time with the same batch of ink, and will generally be pretty much the same shade. Papers from a different run will be a slightly different shade, and will be very noticeable if placed next to one another on the same wall. This is true even with this recycled magazine page material – see the third photo – although instead of printing with ink, the ladies who manufacture this stuff (usually in China or somewhere in Asia) are grabbing handfuls of magazine pages. As you can see, color variations are still quite possible / probable.

In addition to the 10′ high ceilings, the room had a few features that made the install tricky. One was a deeper than usual vanity, which was difficult and somewhat dangerous to reach over to access the wall. This was also a “floating” vanity, which hung suspended on the wall with a short space underneath it that wanted to be covered with wallpaper. Contorting myself under a 30″ deep vanity into a 5″ high space to stick a couple of strips of paper to a rear wall that no one would ever see questioned my sense of reason – but I could not imagine leaving the wall unpapered, so I “got ‘er done!” Sorry, no photo.

Being a contemporary styled home, the window was recessed with a 1/2″ return,. This meant that I had to bring the paper to the edge of the window, and then wrap a mere 1/2″ around an outside corner. The paper was thick and didn’t want to make this turn, and, when it did, it didn’t want to stay stuck – it kept trying to lift up. Wetting the paper helped soften it so it was more agreeable to making these turns, and in some areas I also used a razor blade to make light horizontal slits in the material, right on the edge of the corner, to reduce tension and allow it to turn more easily. Sorry, no photo.

Speaking of making cuts … This stuff was thick and hard to cut, so it took a lot of pressure and several swipes to make many of the cuts, even with a brand new razor blade. When I trimmed the material horizontally at the ceiling and floor, the strings that held the folded magazine pages to the backing were cut also, and they came loose. That meant that there was nothing holding the folded magazine pages to the paper.

It turns out that each of those horizontal strips of folded magazine pages contained about 6 layers of paper, each folded accordion-style. Threads were sewn on to hold them to the backing. But once the threads were cut, the accordion-folded papers unfurled, spread apart, and pushed away from the backing. So when you looked at the ceiling or floor lines, you saw a puffy ridge running the width of the strip.

What I ended up doing was to go up to the ceiling and then down to the floor edges, gently pry apart the fanned layers, and use wallpaper paste to adhere them to one another. I had to get sufficient paste behind each of the six layers, for the entire 3′ width of each strip, press them back together, hold them until the adhesive tacked up – all without getting any paste on the paper or on the ceiling.

All of the above added a lot of time to this job, and I didn’t leave until 9:30 p.m. But the room looked great when I was finished. From its initial uninspired dull grey paint job to the colorful and quite unexpected recycled magazine pages covering the walls, this powder room has experienced a major transformation.

The wallpaper is by Seabrook, which has been purchased by York. Both are wonderful brands.

Same Run – But Color Difference

June 8, 2018


One of the first things the installer does before starting a wallpaper job is to check the run numbers, to be sure it is the same for all the bolts of paper. This means they were all printed at the same time with the same batch of ink, so they will all be uniform in color.

Both these bolts are from the same run. But look closely, and you will see that the blue lines on the strip to the right are darker and thicker than those on the left. If these two strips of paper were placed next to each other on the wall, the difference would be very visible.

I am glad I noticed this before I started cutting any strips. I set aside the errant bolt, and hopefully won’t have to use it (I always have my clients buy a little extra, for repairs later and in case of instances like this). If I do need to cut into this bolt, the bathroom has a lot of choppy areas that are on separate walls where the color difference won’t be noticeable.

Minimalizing Color Variations by Hanging in Sequence

May 13, 2018


Because grasscloth is a natural fiber product, it is known for certain inherent features, namely a pattern that cannot be matched, visible seams, and color variations such as paneling (one strip is a slightly different color from the one next to it), shading (different colors within the same strip), and edges that are lighter in color than the center of the strip. Just do a Search here to see pictures and read stories.

This manufacturer (Thibaut) has taken steps to minimize one of these issues. First, you want to be sure that all your bolts were printed at the same time, from the same run or dye lot (see label). Next, when a whole lot of wallpaper is printed at one time, the ink color can change ever so slightly from the beginning of a run to the end.

So Thibaut lists not only the run number, but the sequence in which the bolts were printed. On the label, this is referred to as “Shade.” The instructions are very specific about cutting and hanging strips of paper in the order they come off the roll, and using consecutive rolls in their proper order.

However, for this 11 bolt living room, I got 8 bolts of Shade series 4 (#’s 1-8), and 3 of Shade series 5 (#’s 7-9 … and what happened to the first six?!). These obviously were not printed in consecutive order! And they were all mixed together in the boxes. Good thing I checked the labels and noted the Shade numbers, before I cut anything up.

Luckily the layout of the room worked so that I was able to keep Shade 4 and Shade 5 on separate walls, so any slight color difference would not be noticeable.
