Paint Splatters and Over-Brushing

This is baseboard in a corner of a room where I will be installing wallpaper . The blue is my dropcloth .

Wow.  Look at the paint splatters on the baseboard .  Maybe the paint was thin , or the painter was working too fast, causing paint to fly off the roller cover .  This could have been prevented by placing wide blue painters tape above the molding , or by covering the baseboards with strips of dropcloth or plastic .  Do a search here to see my previous posts about my technique .

Later, the room décor changed, and the grey paint was covered with pink paint.  Here you see where the painter let his brush swipe paint onto the top surface of the baseboard.  He did the same thing with the underside of the crown molding at the ceiling , too.  This is one of my pet peeves.  Looks so bad.  They do it because it’s easier than “ cutting a clean line .”  To do it right, all it takes is a good angled trim brush and a steady hand , and patience .  Or, use blue tape or even a trim guide to keep paint off the woodwork . 
I’ll probably take some white craft paint to color over this, before hanging the wallpaper .

Challenges With Moody Jungle Powder Room

Yesterday’s install was quite fun, but there were some unusual or challenging features to the room. Here are some of them.
First, in most areas, the chair rail had a sort of gap between it and the wall, probably then filled in with caulk. I used some craft paint from Texas Art Supply to color that in, so there wouldn’t be white showing between the dark green paint and the black wallpaper.
My usual trim guide (not pictured) is thin, designed to allow you to cut very close and tight to the edge. But in this case, I was afraid it might leave some of that gapped area showing between the paper and the wood trim.

So I used this steel plate tool, which is thicker and would allow me to get a fat cut – just enough paper left to wrap a teeny bit onto that gap area. Note that before I trim, I’m going to press that edge into the corner. I couldn’t hold the camera and hold it in proper position at the same time.
Also, you’ll notice the rolled edge at the top of the tool. That’s thicker, and allows for getting an even fatter cut, for instance, when you want just a tad of paper to wrap around a corner . Do a Search to see my previous post about this technique.

Here I’ve made the trim cut and am peeling away the excess that was trimmed off at the bottom.
See how the bottom edge of the wallpaper now wraps a tiny bit and fills the gap neatly?

Next issue – wall height. On this wall, the height is 3′ + 30.5″

But on the opposite wall, the height is 3′ + 29.75″.
This means that you can expect the ceiling to move up or down, which means that a pattern motif – let’s say one of those cute chameleons – could get his head chopped off by the descending ceiling.

Next issue – bowed wall. Here my yardstick is sitting pretty squarely against this wall, in a corner .

But as I move it up the wall a little further – wow! – that wall takes a dip to the left. And it’s quite a dip! The wall has a bow in it.
I can get my next strip of wallpaper to cover that space. But the fallout will be that pattern motifs will hit the wall at different points, which means that the next piece to be placed after that, the pattern will not match perfectly at all points.

All right. So that previous corner had a bow. This one is out of plumb. Here you see my laser level showing that my wallpaper strip is hanging nice and plumb.

But move the laser to the corner and you see that it’s out of plumb .

Here’s a better example. Again, this causes the pattern to not match perfectly in the corners.

Another shot of the bowed wall, which, for various tech reasons, due to Word Press ‘s crappy New Editor , this shot got out of order and I was not able to place it with the others under the topic.

Papering around the electrical outlet , I had to unplug my light source. There was light coming in from the hall. But this paper, as well as the paint, were so dark that I couldn’t see well to work. Enter my Big Larry flashlight .

Small enough to fit in my toolbox , but really bright and dependable for when you need it.

The pattern is called Fantasy Tree and is by Breeze and was purchased through one of the showrooms in one of Houston’s decorative / design center s. It’s a nice non-woven material , easy to hang , easy to remove , durable and stain-resistant .

What’s A “Fat Cut” ?

Here, I’m hanging paper from right to left, and have just come around a corner , which is in the center of the picture. You almost never wrap wallpaper around an inside corner . Corners are never straight , and the paper will buckle in the corner . And the edge will not be straight , nor plumb , and thus the next strip won’t butt up perfectly against it . And it’s also probable that the strip will torque off either up or down, causing your pattern to creep up or down the ceiling and floor lines.
The answer is to stop the strip of wallpaper in the corner , and cut a new piece for the subsequent wall.
But you can’t just trim tightly to the corner. Because most likely there will be gaps (remember I said that corners are never straight?), so some of the wall will show.
So what you do is wrap the paper just a teeny amount around the corner , and then overlap your new piece over that. This does mean that you will lose some of the pattern in that overlap.
I can’t stand that pattern mis-match, so most of the time, the way I do it, I’ll take a fresh strip of wallpaper for the next strip (to be placed on the left in the photo) and trim it so the pattern matches as perfectly as possible. But I’m getting ahead of myself. Back to the fat cut …
In the photo, I’ve cut my strip on the left 1/2″ wider than needed to fit this wall. I don’t want this 1/2″ of wallpaper under my overlapped new strip, because the leaves a visible ridge. But you do want a little underlap, because you need that to prevent a gap from showing in the corner.
So in the photo, I’ve trimmed off most of that 1/2″ and trimmed it down to an unnoticeable 1/8″. How on earth can you get a trim that thin and that consistent?!

I use this handy metal plate with a rolled edge (on the left).

This plate has bends and other edges of other thicknesses , rounded edges , won’t leave marks on wallpaper, so it has many uses.

Here’s a close up of the trim guide edge that allows for that 1/8″ fat cut .

Back side of the plate. (Don’t mind the blue tape – it’s just there temporarily.)

This edge is a little thinner , and would cut too close for use in a corner. But it does have a use if you need a trim in an area where you don’t want the paper trimmed tightly into the edge / corner.

You’re looking at where wallpaper meets crown molding. This join edge has gaps between the molding and the wall in some areas, and other areas have gunk and uneven areas. Trimming with my usual trim guide would cut too close and let some of these icky things show. So here I’ve used the thicker trim guide. As you can see, it allows the wallpaper to wrap ever so teeny much of a bit, so it covers the bad area, but doesn’t creep onto the molding.

Here’s another example, along door molding. At the top, I used my usual thin trim guide (see below). But this allowed a bit of a gap to show, due to decades’ build up of paint , caulk , dirt , etc.
So, midway, I switched to using the steel plate as a trim guide. This made the cut just fat enough that the wallpaper wrapped a hair and covered the icky area.

Here’s my usual trim guide . I’m guessing it’s about 9″-12″ long .

You can see that the edge is very thin . In most cases, this is ideal, because it allows for good, tight trims right smack into corners and edges.
That steel plate shown above was invented by a colleague in the Wallcovering Installers Association ( WIA ) . They are all the same length, but they come with three different degrees of angles , and can be used for lots of wallpaper installation tasks .

Arts & Crafts Style Frieze in Heights Bungalow

Dining room before. This bungalow in the Woodland Heights neighborhood of Houston is very true to the Arts & Crafts / Craftsman period. This style featured straight , clean lines , nature , and muted colors that mimicked those found in nature . The homeowner is a retired woodworker / carpenter and did much of the millwork you see here.

Done. The teal green is actually a little more muted than the photo shows.

From another angle.

Close-up. This wallpaper pattern is called Fir Tree .

A frieze is a wide wallpaper border , usually run around the middle or top of a room . The manufacturer is Bradbury & Bradbury . They specialize in period-inspired patterns from past eras, such as Victorian , Arts & Crafts , Oriental , Modern Age / Mid Century Modern , and more.

Bradbury prints on stock that’s about 28″ wide, and this border is about 13″ wide. So Bradbury prints two borders side-by-side , and then you need to use a straightedge and razor blade to cut them apart .

Although the border came about 13″ wide, the space between the beams was only about 11.5″ . So we were going to lose about 2″ . I consulted with the homeowner. He really wanted to see the copper metallic pine cones. We also felt the trunks of the trees were important design elements . We decided that the pattern could afford to lose more from the top , which would permit more of the tree trunks to show, all the while preserving those pine cones.
Here I am trimming 2″ off the top, so the overall height of the frieze is now 12″ . That will fill the space between the beams, and also allow a little bit to tuck down below the bottom beam (there is a gap between the wall and that beam).

The room was really dark , the wallpaper was dark , and my straightedge was casting a shadow where I needed to trim. So I grabbed my Big Larry flashlight from my toolbox and was able to see where to trim.

Bradbury uses inks that are quite delicate , and can be scratched or marred simply by brushing with my smoother brush , or my plastic trapezoid squeege smoother tool . Metal – like a trim guide or scissors – will also leave marks on it . Here I’ve wrapped tools in microfiber towels and baby socks , to soften contact with the wallpaper .
Bradbury inks and substrates can be finicky, and it’s important to use the paste recommended by the company for the particular colorway that you’re hanging . In this case, I had to use clay – based paste .
The inks and substrate aren’t always compatible , so when you add wet paste to the back , it can cause the substrate to absorb moisture and swell , while the inks on the surface are holding tight. This will result in wrinkles , warps , and bubbles on the surface . We call this quilting or waffling .
One trick is to lightly sponge clean water onto the inked surface. This will allow the surface to absorb moisture and expand hopefully at the same rate as the backing , hopefully eliminating wrinkles and bubbles .
On this install , I still had problems with uneven expansion . And with the paper drying out before I could get an entire strip up on the wall. So, while I was pasting the back, I also sprinkled a little water on the back and mixed it in with the paste . This did seem to even out moisture , and also help the material remain moist and workable during the installation .
In addition, I also had trouble with the edges of the paper drying out before I could get a full strip up on the wall. Part of this was because it’s winter time and the furnace was blowing hot air into the room and drying out the paper. My counter-attack was, again, to sprinkle a little water onto the back, to hydrate the material more. Also, once I had pasted a strip and rolled it up (see below), I dipped the edges into about 1/8″ of clean water. And then wrapped the pasted material in a plastic trash bag and allowed to book for a few minutes before hanging . This is standard procedure with wallpaper. Actually, what worked better was to paste, book, bag, and then just before hanging to dip the ends into water. This seemed to keep everything wet and workable better and longer.
Despite all this, some small bubbles did remain in the paper. As the paper dried, though, they flattened out.

When you book a strip of wallpaper, customarily you fold the top 1/3 down and the bottom 2/3 up. This keeps paste from smearing all over everything, and makes each strip shorter and easier to handle. And allows you to get the top section of the pattern lined up with that on the previous strip , before unfolding the bottom section and working that against the wall.
But it’s a little different handling a narrower border that’s maybe 12′-15′ long. What I do to make this manageable is to book the material in accordion pleats . See photo. Then I can unfold just a small section, work it into place, and then move along the strip, smoothing just a small section at a time against the wall.
Actually, with this install, I positioned my sections against the wall temporarily, to get the whole 15′ strip up there. And then went back and smoothed each section against the wall, working out bubbles and warps , and ensuring that the frieze was pressed tightly against the wall at both top and bottom .
There were four strips around the top of this dining room. On each strip I used a different install method. By the time I was done, I had learned how the material wanted to be treated.
The homeowners are in love with this period-authentic look for their vintage bungalow. The husband said it was like Christmas, because they had waited for so long to have this room completed, and now it’s finally finished and beautiful!

Tools For Double-Cutting / Splicing

I mentioned in yesterday’s post that double-cutting was needed for that vinyl mural installation. This type of trimming is often used in commercial vinyl jobs (hotels, hospitals). Above are some tools that help make it go more smoothly.
~The clear plastic tape on the right is made of polystyrene plastic. It’s flexible, but thick enough that you can’t cut through it with a razor blade. It’s used to ” pad ” the wall under where your cut will be, so it goes from ceiling to floor. It’s wide enough that you can straddle where your seam will be, and have 2″ or so in which to make your cut. This stuff is really important, because you never want to score into the wall surface, nor even into the primer . If the wall surface becomes un-intact , then when the wallpaper paste dries and the paper shrinks a bit, it puts stress on the seams. If the wall is not intact under those seams, the wall surface may give way and you end up with a ” popped ” seam. It’s not the paper coming loose – it’s the wall itself coming apart, and is difficult to repair.
~The roll of thin blue tape is used to keep paste off the wallpaper. You put it on the under side / pasted side of your second strip where it’s going to overlap onto the strip that is already on the wall , which is the area where your splice cut will be made. This blue tape can be used for other purposes, too, when you want to keep paste off the ceiling , for instance, or your last corner where the last strip meets up with the first strip.
~That metal tool is a 20″ long trim guide. It has a non-slip strip under the left edge, and a point at the top to get right up against the ceiling. The handle makes is super easy to hold and manipulate . This comes in both shorter and longer lengths.
~All of the above were invented and are sold by members of the Wallcovering Installers Association . Contact me if you are interested in purchasing.
~And, of course – razor blades. When I D/C, I usually hold a single edge blade in my fingers. But some installers use a snap-off blade in a holder. Whatever works best for you!
~Once your trim cut is made, of course, you need to remove the two tapes, the cut-off strips, and then smooth the two pieces back into place.

Grasscloth Engineering and Logistics – Technical Details Post

Grasscloth is a natural material that cannot be matched from strip to strip, so all the seams will be visible . In addition, there is usually a slight but noticeable color difference between strips / panels (called shading or paneling ) . So it’s important to plot the layout of the strips to give the most visually pleasing overall look. Usually this means balancing the width of strips so they are all equal , at least on the same wall . We call this engineering .
This wall presented particular challenges , due to the widths of the elements. Grasscloth comes 36″ wide . You can use your straightedge and a sharp razor blade and trim it down to any width you want.
The width of both the large wall spaces to the right and left of the bank of windows was 34.” The width of each window was about 35.” The width of the two spaces in between the windows was 7.”
So you’d think I could trim my panels on either side of the windows, and then over the windows, to about 34″-36″ – give or take a few inches (or fractions thereof).
But that would leave me with two 7″ wide strips between these 35″ panels. Although the look would be uniform and mirror-image from the center outward, moving from right to left you’d have: 35,” 35″, 7,” 35,” 7,” 35,” 35,” … those 7″ breaks were just not going to look right.
One option was to determine the width of the wall (189″) and make each strip an equal width. This worked out to six strips, each at 31.5″ Not good, because this would mean a seam down either far side. And since those sides were 34″ wide, that would mean a 31.5″ wide strip and a strip 2.5″ wide. Not attractive at all, and it would use up an extra strip of wallpaper.
This six strips @ 31.5″ wide scenario might also land with a seam smack in the middle of those 7″ wide interludes in between the windows. Not attractive at all.
So I decided to make the two outer strips 35″ wide. That left 119″ of wall space above the windows to be covered with wallpaper. Do some math and you get four panels of 29.75″ wide. This gave a balanced and uniform look to the area over the windows, and also prevented seams from landing between the windows.
Moving right to left, I cut and hung the full length outer strip first. Then I cut and hung the strip over the window on the right. Then I measured to find the centerpoint of the window in the middle. Turns out it was a bit less than 29.75″ away. So I trimmed that next over-window strip accordingly.
Once that was in place, I measured from that center point above the middle window out to where my left full-height panel would fall, 35″ out from the wall. Took the resulting measurement and divided by 2. Lo and behold, each of the next two panels over the window was going to be a bit wider than 30.” No problem. No one (but a paperhanger or maybe an engineer) is going to notice a 1/4″ or even a full 1″ difference in widths between this strips over the windows.
Another thing to point out … it’s important that I took measurements before cutting these strips for this second left-hand section. Because, since grasscloth comes at 36″ (and walls can be wonky), if my strips had been narrower (say, 28″), that last full-height panel on the left might have ended up needing to be 37″ wide – and that wouldn’t work because it only comes 36″ wide – plus you need at least 1/8″ to wrap around the corner.
Luckily I had the flexibility to be able to trim the panels over the windows to any width needed, to accommodate all this.
If you’ve followed all this so far, let me also toss in that we also need to figure how to get paper in between those windows. More on that below.
In this scenario, I’m moving from right to left.

Area beneath the windows needs to be treated in the same way, and preferably with widths that match what’s going on above the windows. In addition, it’s tricky because after you move across 12′ of wall space, the strips above and below the windows are going to twist and torque out of shape, so that last full-length panel on the far left might not butt up perfectly with the last strip under the windows.

The grasscloth is black , and my wallpaper primer is white . It’s common for teeny gaps to appear at the seams . In this case, it’s likely that white wall would peek out from those gaps. So I like to stripe under where the seams will fall with dark (diluted) paint . This takes measuring , plotting , and also a heat gun to get the paint to dry before the wallpaper hits it, to avoid staining. You can do a Search here to read more about this technique .
Now let’s talk about getting wallpaper in between those windows.
As you can see in the photo, if I hang a 30″ wide strip, a whole lot of paper is going to be cut off and thrown away. Also, a whole lot of sticky, pasted paper is going to bump against that window molding and maybe even the window glass. A lot to clean up! And unwieldy, to boot.
My solution was to stop the wallpaper just a little below the tops of the windows. Then I would patch in a 7″ wide strip in between the windows. This is trickier than it sounds, because, if it were a paper wallpaper, I could simply cut along a design motif and overlay the 7″ wide piece. But grasscloth is thick and overlaps don’t look good. Also grass has no design elements , and the reeds of grass don’t necessarily fall perfectly horizontal , and even if you cut everything perfectly true to square , if the window molding is a teeny bit off-plumb , then your edges won’t butt up perfectly.
So that’s a good reason for striping the black paint under where the butt join will occur.

Same thing for the sections under the windows. I measured and positioned the strips so that the top edge (which I had trimmed to be perfectly horizontal) fell between the narrowest part of the windowsill molding, for less visibility.
I admit, instead of butting the two pieces, here I did overlap the 7″ wide strip about 1/4″ onto the piece under the window, right at that narrow junction. It’s only about 3″ wide, and I figured no one is going to be examining it that closely, anyway. This saved me about a half an hour of measuring, trimming, testing, repeat, repeat.
This is my second window interlude, and by this time I had realized that it’s hard to trim stiff grasscloth around intricate moldings precisely . So I used paint to fill in the edges around the window molding, just in case there might be any gaps between the grasscloth and the molding, so you would see black instead of the white molding paint. I did this with a small sponge; if I had used an artist’s brush it would have been a bit neater and tighter to the conforms of the molding. But sometimes you’ve gotta relax and realize that no one’s going to be scrutinizing the insides of moldings below shin-level.

Area over windows finished, with drapes back in place.
Turns out this particular grasscloth is so uniform in color (quite unusual, I will add), that you can’t really see the panels , nor their equal widths , anyway. I’m still glad I took the time to do all this math and trimming.

Area below the windows, done. That last seam on the left bears some explanation, too. Moving across the top of the windows, I measured that that last strip – the full-length strip – would need to be exactly 35″ wide. It butted up nicely to the last strip above the windows.
But, due to twisting , shifting , expansion , unlevel and unplumb walls and ceilings , and other factors, there is a really good chance that that last 35″ wide strip would not butt up perfectly with the last 30″ wide strip under the window . So I planned to splice these last two strips together.
Yeah, the drapes are hanging there, I coulda overlapped the two strips about 1/2″ and the drapes would have covered it. With a thin wallpaper, I probably would have done this. But grasscloth is thick, and an overlap would be visible , and also the adhesive / paste can’t be trusted to adhere as well to grass as it would to paper .
So I plotted for a splice. Instead of trimming my last strip under the window to 30″ (read above), I trimmed it to 32″ wide. That way, when I hung the last full-length strip to the left, which was 35″ wide, it overlapped the piece under the window by a few inches. Then I did a double cut and spliced the two pieces. See below for details about that technique.

Grasscloth is 36″ wide, and this wall area is wider than that. So two strips were needed. This means you’re going to have a seam, and since grasscloth seams are always visible, it looks best to plot to have the seam fall down the center. It uses more wallpaper to do this, but it looks much better than having, for example, a 36″ wide strip next to an 8″ wide strip.
As mentioned above, in case you get thin gaps at the seams, a dark stripe of diluted craft paint under where the seam will fall, will prevent white wall from showing through.

Rounded / bull-nosed edges and corners have been popular in new construction for at least 10 years. I wish they’d go away. They’re very difficult to trim around, and hard for the paper to conform to and adhere to.
It’s very hard to trim around that rounded edge, because the paper is hanging over and blocking your view, because grasscloth is thick and stiff and your fingers can’t feel through it, and because the edges aren’t necessarily true and plumb so a laser level or other level won’t help you much.

I use this little gadget as a trim guide. It’s actually a small section of the same corner bead material that drywallers use when they assemble these walls. Cut to about 1″ long and notched in different places where you might trim along the edge of the wall.
It’s intended that you place your trimming knife in one of the notches and slide the gizmo along the edge and make your cut. I find that awkward and also inaccurate. So I prefer to use the notches as a guide and mark where I plan to trim with a pencil. Since this wallpaper is black, I used this marking pencil from my home sewing kit instead. Chalk might work, but I was afraid it might now wipe off completely.
The pink pencil line was barely visible, but it was enough for me to use a scissors to trim along the grasscloth. I like this better than using a razor blade as I can see better, and also less chance of scoring into the primer or wall. Which raises its own set of issues – do a search here to find previous posts.

Inside view of the trim guide.

Finished arch. Note the four panels of equal width above the arch. And two flanking full-height panels also the same widths.
I was lucky that there was no pattern to match, so I was able to butt my two flanking strips right up to the edge of the bull-nosed corner. No trimming needed! Then I measured the remaining width between these two strips (the area over the arch), divided by four, and cut four strips of equal widths.
I hung the two on the left, and then one on the far right. This left one strip still to be positioned to the right of center. So the pieces are going to meet over the arch, rather than the last strip falling in a corner.
Same as the last strip under the window (discussed above), it’s really difficult to get your last piece to fit in here perfectly. I’ve done it, but it takes a lot of measuring, trimming, testing, retrimming, and often starting all over again.
So I did a double-cut / splice.

A double cut involves cutting each strip an inch or so wider than it should be, and overlapping the two. Then you take a straight edge and sharp razor blade and cut through both layers. This handy tool is a wonderful non-slip guide for this process. It was invented by an installer colleague in the Wallcovering Installers Association ( WIA ) and she has them fabricated in various lengths (along with other cool tools ) and sells them on-line. Contact me if you’re interested.
Anyway, it takes a lot of strength to cut through two layers of grasscloth, so somewhat difficult for lil’ ol’ me.
You also want to be sure to not cut / score into the wall, because the tension of drying wallpaper can tug at the wall and cause it to actually come apart, leaving an open seam that’s difficult to repair.
So you’ve got to put some padding under the wall where the cut will take place. I use special strips of polystyrene (hard but flexible plastic) to pad the wall. Also invented by a colleague in the WIA , who also sells other cool tools and supplies. Contact me if you’re interested.

This black grasscloth was printed on a white substrate. If the seams aren’t absolutely tight, there can be worries about the backing showing through to the front. So sometimes we’ll take a piece of chalk or pastel (never oil pastel or permanent markers because they bleed and stain ) and run it along the edge of the paper – from the back, and taking care to not get chalk on the surface.
I do this frequently with dark papers ( do a search here to see previous posts ) but opted not to do it with this grasscloth. It wasn’t necessary, and might have stained the porous reeds of the grass. It was beneficial, though, to have striped dark paint on the wall under the seams, as mentioned above.

Ugh. Grasscloth comes 36″ wide, and this section of wall is 38″ wide. It’s not visually pleasing, nor is it easy from an installation point of view, to have a 36″ wide strip next to a 2″ wide strip. Or to use scraps and put a 25″ wide strip next to a 13″ wide strip.
So best to plan two strips of equal widths. Two strips, each 19″ wide, with the seam down the middle.
Actually, the strip on the left was 19″ wide, but I trimmed the strip on the right to 21″, because I like the wallpaper to extend 2″ over the top of the door molding. This provides a more stable surface in case of shifting foundation or walls, and less likelihood (knock on wood) of the seam opening up should the house / drywall experience shifting.
Note that design “rules” caution against seams down the middle of spaces. But it would have been more visually distracting (and used up more paper) to have made three strips of each 12.75″ wide. And would have looked even dumber to have used scraps left from other walls and put together two strips of disparate widths.
So the homeowner and I discussed during our initial consultation , and she was happy with the center seam. Once it was all finished, this particular grasscloth was so even in tone that you barely see the seams, anyway. Win-win!
This did use up additional paper, though, as noted in a previous photo above.

Getting a “Fat Cut” in Corners – Using a Euni Plate

You never wrap a strip of wallpaper around an inside corner.

Corners are neither straight nor true-to-plumb. So trying to wrap around a corner will result in a warped edge, and most likely a strip that is wonking off-plumb.

So you cut your strip of paper vertically in the corner, leaving a tiny bit wrapping onto the new wall. See second photo.

Your next strip of paper will overlap on top of this narrow wrap.

Splitting the strip and overlapping means that you will cover up and lose some of the wallpaper design. Hence, the less you wrap around the corner, the less of the design will be lost in the overlap.

The thickness of the rolled edge of this stainless steel plate / tool is just perfect as a trim guide! Trimming against the rolled edge will yield a 1/16″ – 1/8″ wrap around the corner. So, when you overlap your next piece (the strip you split in half vertically), you are only losing a fraction of the wallpaper design.

This tool has other uses as well – some are too complicated to get into here. But the thinner edge can be used as a trim guide for regular wallpaper work. It’s shorter than most trim guides, so it can be used in small areas. The rounded edges can be used to press paper into areas, or to crease paper before trimming – without leaving marks. And the angle has a purpose – again, too complicated for here. Plus, there are other plates with different angles available, each with different uses.

This ingenious gizmo was conceived by Eunice Bockstrom, a Canadian and fellow member of the Wallcovering Installers Association (WIA). Once or twice a year, she has a metal shop make a run of these metal plates. Eunice has also invented some other very helpful tools, and they also become available when the factory makes a run of them.

We call all of these Euni Tools. 🙂

Stinky Ink = Curling Seams

Some higher-end wallpapers are screen-printed with an ink that smells like moth balls. We call this stinky ink. And it’s a stinker to work with – because the edges curl badly. The inked surface of the paper absorbs moisture from the paste differently from the backing, so the backing swells and expands, pushing the inked surface away… resulting in curled edges. The top photo shows the edges curling on the pasted and booked strip, and the second photo shows the edges curling on the wall. I tried a lot of tacts, but could not get the seam to lie down.

This paper has a selvedge edge that is to be trimmed off by the installer(straight edge and razor blade and a steady hand). When I tried this standard technique, the seams curled and would not lie flat.

So I tried another approach. I put the pasted but un-trimmed paper on the wall, and then used the double-cut technique. A double cut is essentially a splice – you position one strip, then position the next strip, overlapping an inch or so of the second strip vertically over the edge of the first strip, all while lining up the pattern.

More clearly, you’re overlapping the left edge of the new strip onto the right edge of the existing strip.

Then, using the custom-made trim guide tool seen in the photo, and with a strip of 3″ wide heavy polystyrene plastic (called a Boggess strip, after the guy who invented and sells it) on the wall to protect it from being scored, I used a new single-edged razor blade to carefully cut through both layers of wallpaper.

In the third-to-last photo, I am removing the excess paper left at the seams after this trimming. In the second-to-last photo, I am smoothing the paper back into place. It’s also important to wipe off all paste residue left on the surface of the paper.

Who knows why, but this technique results in nice, flat, tight seams, with edges that do not curl.

Same paper, same paste, same wall – but no curl. Go figure.

Double-cutting takes more time, patience, material, and equipment. But when it’s called for, it might be the salvation for a contrary paper.

Metal Leaves Marks on Wallpaper

There are some wallpapers that can be marred by metal… In the photo, I have purposely run a metal trim guide over the surface, so you can see how it looks.

The bad news is, we paperhangers use a lot of metal items – scissors, trim guide, smoother, and even things like a ring or bracelet could leave a mark, and even my expensive magnesium straightedge, which I bought because magnesium supposedly will not leave marks on paper, will, in fact, leave grey marks where it moves against the paper.

The good news is that most of the time, these marks will wipe off the surface with gentle rubbing with a damp cloth. Of course, you don’t want to overdo that.

The other good news is that, with some extra attention, it is possible to avoid most of these blemishes. Leave your jewelry at home. Blue painter’s tape will seal off the ends of the straightedge, and plastic trim guides can be substituted for metal for some tasks. And care should be taken when using scissors and other equipment to not slide it across the surface of the paper.

Trimming Grasscloth at the Ceiling

Have you ever wondered how wallpaper gets trimmed?

Here I am, using my trim guild to hold a strip of grasscloth tight against the joint between the wall and ceiling, and using a razor knife to trim off the excess.
