Grasscloth on Bookshelf Backs – Railroaded

July 29, 2021
Before, with my primer in four cubbies, two more to go, and my fan set up to get it to dry faster.
Finished.
“Railroading” means the paper was run horizontally, instead of vertically. With grasscloth, this means the reeds ran up and down, instead of sideways. This technique eliminated seams (run the usual way would have given us a seam smack down the center of the shelf area – a decorating no-no).
I was able to slide the edges of the paper under the back side of the wooden shelves. No trimming needed. And no gaps showing between the wall and the shelves.
For this stiff grasscloth material, instead of my softer, natural-bristle smoothing brush (right), I chose a stiffer, plastic-bristled brush.

Manufacturer is York, a very good company.

Coloring Edges of Wallpaper to Prevent White Backing from Showing

July 22, 2021

When hanging a dark wallpaper, sometimes the white edges of the substrate will show at the seams. Other times, the paper may shrink a tad when the paste dries, and teeny gaps may appear, again, showing white at the seams.

So I will often run a stick of chalk along the edges of the strip of wallpaper – applying from the back, to avoid getting color onto the surface.

It’s important that you use chalk, and never oil pastels. Oil products may bleed into the wallpaper, and cause visible staining on the surface.

Preventing White From Showing At The Seams

Chalk pastels for coloring the edges of the wallpaper. (Do NOT use oil pastels – they stain wallpaper.)
Craft paint from the hobby store used to stripe the wall where the wallpaper seams will fall. Note the red vertical line from my laser level, which serves as a guide. I use a small square of dampened sponge to wipe on the paint. Be sure to let it dry before hanging the paper.

Manufacturers have a bad habit of printing dark wallpapers on white substrates. Since wallpaper expands when it gets wet with paste, and then shrinks as it dries, you have the potential for the white edges of the paper showing at the seams. There is also the possibility that the white wall behind the paper will be exposed, too.

To minimize these chances, I use chalk pastels to color the edges of the wallpaper, and diluted craft paint to stripe under where the seams will fall.

Overlapping At The Seams

June 30, 2021

Re my previous post … the strips on this 6-panel mural are intended to be overlapped, by about a full inch.

There are advantages to this. Since wallpaper shrinks as it dries, it an result in gaps at the seams. Overlapping the seams prevents that.

Wallpaper that is drying and shrinking is also tugging at the wall behind it, which puts stress on the surface. If that surface is unstable, this tension could cause the layers inside the wall to give way and pull apart, resulting in open seams and a delaminated sub-surface. Overlapping the paper redistributes and minimizes the tension, and it also eliminates an open area where the two sides of the seam could pull away from the wall.

A disadvantage of the overlap method is that you can see the cut edge of the paper (see photo), and you also end up with a 1″ wide ridge running under the paper the full length of each seam. In this case, with such a busy pattern, you are not going to see that ridge.

Clipper Ships / Battle Ships Mural

Manufacturer is Rebel Walls, from Sweden. I like their products.

A baby boy is due in a few months. For his nursery, Mom wanted an action-packed, historic nautical look. She found this mural on RebelWalls.com

Usually you see a mural on one accent wall. But here we have two companion murals on opposing walls in this nursery. I think it works swimmingly! 🙂

The mural was custom-sized to fit each wall. The website also allows the option to choose which portions of the design you want. So Mom chose to put the largest battleship on the main wall that you see when you walk into the room. A smaller ship and quieter scene was plotted to go on the opposite wall.

I will note that, on both murals, the company did include some motifs that were not on the customer’s order sheet. That changed the dimensions and placement of the ships on the wall. It all worked out O.K., though, with the stormy vessels positioned perfectly on each wall.

Custom-sized to fit each wall, the murals came in 8 panels, plus one panel that was just 4″ wide. It was a non-woven material, which is designed to strip off the wall easily and in one piece when it’s time to redecorate. It can be hung via the paste-the-wall method, which is what I did today. It can also be hung the traditional way, which is to paste the paper. The seams are virtually invisible.

This home is in the Garden Oaks / Oak Forest neighborhood of Houston.

“Her Room” Goes Bright & Colorful

Walls smoothed and primed, ready for wallpaper
Flowers, birds and – COLOR!
Reminds me of this Pierre Frey which I hung in a nursery a few weeks ago.

Home office, craft room, veg-out room – whatever the “official” description, this room in the front of the house belongs to the lady of the house. She loves birds and flowers and bright colors, and was thrilled to find this wonderful wallpaper pattern on Anthropologie.

Most of Anthropologie’s papers are by York, in their SureStrip line, which is one of my favorites. The material is pre-pasted. I like to sprinkle water on the back and then spread it around uniformly with a paint roller, and then book for a few minutes in a plastic trash bag.

The paper goes up beautifully and the seams are invisible. SureStrip is designed to pull off the wall easily and in one piece when it’s time to redecorate.

Paint Pulling Off Wall Where Tape Was Removed – Surface Stability Test

May 12, 2021

It’s important to have a stable surface under wallpaper.

That’s because, when wallpaper gets wet with paste, absorbs moisture from the paste, and it expands. Then, as it dries, it lets go of the moisture and shrinks. When wallpaper dries and shrinks, it puts tension / torque on the walls.

If the surface under the wallpaper is not stable, the tension of the drying wallpaper can cause the underlying surface to pull away.

This photo is not showing the wallpaper pulling away from the wall. What is happening (usually) is that the paint (or whatever has been applied to the wall), has actually delaminated (come apart) from the wall.

This results in a “curled” seam, or a “popped” seam.

One way to test for this is to apply a strip of tape (blue painters tape, tan masking tape, clear Scotch tape, or other), let it sit a few minutes, and then yank it off. If the tape takes any paint along with it, you have a potential problem of the wallpaper not adhering correctly.

This is why it’s important to:

1, Before applying any coating, you must remove all dust from the wall, using a damp sponge, which must be rinsed frequently

2, Before hanging paper, a primer formulated specifically for wallpaper should be applied / rolled on and cut in to edges

A wallpaper-specific primer is designed to withstand the torque put on the wall as wallpaper dries. And it facilitates installation by allowing sufficient “slip” (maneuvering the paper) and “stick” (adhesion). The chemistry behind all this is fascinating – but too complicated to get into here.

If a wall is too “iffy,” and you don’t feel like the mess and expense of scraping off all the old paint, a liner can be applied before the actual wallpaper is hung.

A liner lessens the drying time of the wallpaper, which reduces the time there will be stress on the wall. A liner also redistributes stress on the wall, so much less chance of having seems detach from the wall.

A liner also adds additional cost to the job – for both material and labor, which may include an additional day(s).

Wild & Crazy & Fun Tiger Wallpaper

April 28, 2021
Before. The textured walls have been skim-floated and sanded smooth, and then primed.
Welcome to the Jungle!
Notice the watercolor-y look of this design. It reminds me of impromptu sketches by artists who work in “plein aire.”
“Frida” by Pepper Home

The homeowner was browsing Pepper Home’s website and was instantly smitten by this rather uncommon theme and design. It’s called “Frida.” It sure is fun!

This paper is sold by the yard, was custom-printed, and came in one continuous bolt (54 yards!). It had a selvedge edge that had to be trimmed off by hand (see future posts). The inks are clay-coated, which imparts a rich matt finish, and the substrate is way better than what many other companies are printing on.

I positively loved working with it. The trim marks were spot-on, minimizing a pattern mis-match at the seams. Once pasted and booked, the material became very supple and flexible, and it could be “worked” much better than standard brands. Even better – the seams virtually melted away (became invisible).

I ran silicone caulk along where the wallpaper meets the top of the sink. This will prevent splashed water from pooling on the sink and then wicking itself up into the new wallpaper – which could cause the new wallpaper to curl and peel away from the the wall.

The home is in the Memorial area of Houston.

Whoops! Someone Painted Over Old Wallpaper

April 21, 2021

Just looking at the walls, I had not noticed . But when I removed the light switch cover, it was clear that someone didn’t bother to remove the old wallpaper, and just painted over it.

Actually, they probably did do some prep, because you could not see seams under the paint. They must have taken steps to cover the seams.

And there was no flashing … difference in texture between paint over wallpaper, for instance, and paint over smoothing compound that was used to disguise those seams.

And there were no bubbles (caused by latex paint on top of wallpaper that absorbs moisture from the paint and swells) and only a few tiny loose areas.

Still, it would have been better if the previous guy had put some effort into removing the wallpaper, and then washing the paste off the wall and then sealing with a stain blocker, to prevent paste residue from causing the new paint to crackle and flake off the wall. Then the room would be adequately ready for paint.

Realistic, Textured Faux Brick Wallpaper Accent Wall

April 8, 2021
Textured wall skim-floated smooth, primed, and ready for wallpaper.
Starting in center to balance off-level ceiling line.
Pretty realistic!
The material has a slight texture, although it’s not visible in this photo.

Originally, the homeowner, a single guy in the Houston Heights, had a sort of Asian theme in his master bedroom. But he was ready for something more guttural and free form. Mission accomplished!

The new look is a little bit Industrial Modern, and a little Back Alley. 🙂

He has a lot of sports memorabilia, and I think that would look great hung on this faux brick wall.

The ceiling line was not level at all, which means that you can expect the bricks to not line up perfectly straight across the wall at the ceiling. Bricks would be taller on one end and cut shorter at the other end.

And so I started hanging in the middle of the wall, butting my strip up against a plumb line from my laser level. Moving across the wall, as the ceiling line starts to track up or down, by starting in the middle, you even out any wobbling of the pattern at the ceiling by spreading half of it on the right side of the wall and half at the left side.

As it turned out, the bricks stayed perfectly straight across the ceiling line.

This is a lightly textured, embossed vinyl product by Akea, a British company. I was really expecting a non-woven paste-the-wall substrate. But this was on a paper backing, which you don’t see often these days, especially with the European manufacturers.

It was thin and flexible, the seams laid down nicely, and no bubbling (bubbles are pretty typical with paper-backed vinyl goods).
