Dark and Moody Bedroom Accent Wall

August 4, 2022
The wall has been skim-floated and sanded smooth , primed , and is ready for wallpaper .
The homeowner did a great job coordinating the wall and ceiling paint with the colors in the wallpaper.
This is a room that’s made for sleeping!

At first I thought the pattern scale was too small for the large wall. But once I saw it on the wall, I really like the way it fills the space.
To me, this pattern has a sort of calico look.
Close-up shows the light texture on the paper.
This is a non-woven material, so I’m installing via the paste the wall method . Here I’ve cut and arranged all my strips in the order in which they will be hung . This is a drop match pattern , which some folks think of as A and B strips. Meaning, for instance, an orange flower appears at the top of the wall on Strip A . But the next strip, Strip B, has a yellow flower at the top. When you get to the third strip, we are back to an A and an orange flower. Next comes another B strip – and so on.
I’ve rolled the strips backward , with the top of the strip coming off first. This will prevent the printed face of the wallpaper from bumping into the pasted wall during installation .
Wallpaper often shrinks a tad when the paste dries , and this can result in very minute gaps at the seams . With dark wallpapers , it’s pretty important to take steps to prevent white from showing at these gaps. Here I’ve measured out where each seam will fall, and taken diluted black paint to make a dark stripe under each seam . I don’t make the paint full-strength, because wallpaper paste isn’t formulated to adhere to paint. I want the wallpaper adhering to the primer I’ve applied. That’s also the reason why you don’t want to roll paint over the whole wall.
Also, I have only striped some of the seam areas, and will wait until some strips are up on the wall before striping more lines. This is because wallpaper expands when it gets wet with paste, which can make it difficult to plot the exact width of each strip as you move across the wall.

I use acrylic craft paint from the hobby store, applied with a bit of sponge. I keep a small dish of water to dip the sponge into, which dilutes the paint a bit.
You also see a stick of chalk pastel . See next photo.
Besides the wall peeking out from behind the wallpaper seams , it’s also possible / probable that the white edges of the wallpaper backing / substrate will show at the seams. I take a stick of chalk and run it along the edges, making sure to apply from the backside, to avoid getting chalk onto the surface of the wallpaper.
Be sure to use chalk pastels and not oil pastels – oil will bleed and stain wallpaper. Some installers use liquid paint or markers – again, be sure to use water-based or acrylic , and never oil based or permanent markers .
BN Walls is the brand. Altogether, this was a pretty nice product to work with. It was thin and very soft and flexible (many non-wovens are not).
I wasn’t happy with all the seams, though. I believe the paper was cut with dull or wobbly wheels at the factory, because the edges seemed to not be perfectly straight . So I ended up with gaps and overlaps in some areas. Here you can see the wallpaper edges pouching up a bit due to excess paper.
But, as I mentioned, this material was quite flexible, so it was pretty easy to spread these edges apart an use a tool to push them apart and then down to prevent them from pouching up again. Once the paste started to dry, these areas held nice and tight and flat.

Narrow Strip Coming Out of a Corner – Keeping It Straight & Plumb

March 31, 2018


OK, this is a little difficult to explain, but hopefully you can follow along. I have hung paper above this door from the right and am heading toward the left, and ended in the corner. The next strip will be 9′ high, and will be narrow, having only 3″ on the wall to the left of the corner, plus 4″ wrapping around to the right of the corner and ending up against the door molding.

The problem is, a narrow strip of paper like this, coming out of an inside corner, and especially in homes with un-plumb and un-straight walls (like this one), the left edge of that narrow strip of paper is likely to not fall straight. This will be a problem when trying to get the next strip of paper to butt up against it. I didn’t want any gaps or overlaps or white wall peeking through the seam.

So I pasted up both the narrow first strip, and also the full width second strip that was to go to the left. I positioned the narrow strip, but didn’t press it firmly against the wall. (This is called keeping it open.) Then I positioned the second strip next to it, matching up the pattern, but also not affixing it to the wall.

I used my laser level to shoot a vertical line along the left edge of that second strip of paper (the red line slightly visible in the photo). This ensured me that both strips were hanging plumb. I had to reposition the second strip a bit, to be sure it aligned with the laser’s plumb line. Then I took my smoothing brush and pressed it against the wall.

Then I went back to that still-open narrow strip to the right, and maneuvered it around until the pattern matched and the two edges butted together nicely. I smoothed the 3 inches into place on the wall to the left of the corner, and then did the same with the 4 inches that fell to the right of the corner and met up with the door molding.

Beautiful!

It was actually a little more intricate than that, because of having to keep the pattern matched to the piece already in place above the door, and due to stretching of the paper as it was pulled away from the wall several times, and the shiny surface being prone to blemishes if it got creased or overworked.

It was worth the trouble, though, because keeping the edges straight meant that the seam butted together perfectly, with no gaps and no overlaps. And keeping the paper plumb meant that the whale motif at the top of the wall stayed where I wanted it. (If paper goes off-plumb, a design motif will start moving up or down the ceiling line.)

This fun swimmy pattern is called Melville and is a non-woven, paste-the-wall product, made by Cole & Son.
