Bridging A Gap

These are the plumbing stems for wall-mounted handles and faucet in a powder room in the Heights neighborhood of Houston. The homeowner had the fixtures removed to make the wallpaper installation easier and with fewer ” relief cuts ” in the paper. This helps to eliminate chances of splashed water hitting open edges of the paper and wicking up inside, which can cause curling at the seams.
But the holes were a tad too big for the escutcheons (decorative back plates) to cover. The hole around the left handle gaps about a half an inch outside the plate (not pictured).

I wanted to close that gap a little bit, and also to provide a firm surface for the wallpaper to stick to. I cut ” collars ” out of scrap non-woven material. This material is very strong, and won’t stretch or warp out of shape. Non-woven makes a fine substrate for today’s wallpapers. In the photo, I have placed them around the plumbing stems.
I impregnated the “collars” with Gardz, which is a penetrating primer which soaks in and binds surfaces together, and then dries hard – a lot like varnish or shellac.
Then I skim-floated the area with drywall joint compound (” mud “), let dry, sanded smooth, wiped off dust with a damp sponge, and then primed with Roman Pro 977 Ultra Prime, my favorite wallpaper primer. So this photo shows the finished task. When the plumber comes to re-install the faucet, etc., if the holes are too small, he can simply cut some away.
Now that the opening is smaller, the escutcheon easily covers it.

Farrow & Ball – Disappointing Quality

October 10, 2019


First three photos – Burnish marks from smoothing paint-coated paper to wall. Read below.

Last two photos – Fat seams caused by poor trimming and thick paper and paint. You man need to enlarge the photo to see clearly. Read below.

I’m disappointed in the quality of the Farrow & Ball paper I hung recently. (See my post from September 1st.) For a high-end brand, their quality-control is definitely lacking.

The seams are thick and dark, and many areas had to be repasted because they didn’t hold to the wall. As one of my highly-skilled, decades-long installer buddies put it: “This is a common problem caused by …… incompetence of factory trimming and poor choice of substrate. This substrate is thick and the trimming from F&B often gives us a “rounded” edge, for want of a better word.” Another installer described the seam edges as “scalloped.” You can never get a good, tight seam with thick paper and paint, and improper factory trimming.

Another disappointment was a sheen on the paper. F&B is proud of their paint, and, instead of using ink (like other successful manufacturers do), they coat their wallpaper with their paint. To get wallpaper stuck to the wall, to eliminate bubbles, and to set seams, you need to use tools, notably a smoothing brush (“sweep”) and/or a plastic smoothing tool.

No matter how gently I swiped with the brush, the paint burnished (left a sheen). Using the plastic smoother to try to coax the cantankerous seams to stay down left worse sheen along the length of each seam. I tried covering the smoother with soft T-shirt cloth, but that didn’t help. This sheen is caused by sensitivity of the paints. I hung three different F&B patterns, and had the same problem with each.
I worked as cleanly as possible, because trying to wipe even a small speck of paste off the surface left another shiny spot. The sheen was more noticeable when the paper was viewed from the side, with light hitting it at an angle.

If other manufacturers use inks that are designed to bond to paper, and that will withstand the light brushing and occasional wiping during the installation process, why does Farrow & Ball persist in using paint on their wallpaper??! Matt-finish paint is designed to be looked at, not rubbed or wiped or washed. And why use a thick, poor-performing substrate, when so many other companies have found wonderful papers to print on??

One solution for the sheen might be to coat the paper with a matt-finish varnish or other product that will even hide the shininess. As for the fat, noticeable seams, there is no solution. For now, we’re leaving everything as it is, because the client doesn’t see what I see, and she is delighted with her new wallpaper.
