Jungle Paneled Installation, Italian Product, for a Nursery

June 22, 2019


The top photo shows a sample panel of the wallpaper taped to the wall of the nursery. You can see the sharply sloping ceiling line to the right.

The mother-to-be fell in love with the jungle theme and the colors of this paper. She bought it on-line from an Italian company. Unlike most wallpapers that come in rolls, this product came in sets of panels, each of which was 27″ wide x 39″ long. In the second photo, you see the first three tiered along the left, and the next two strips positioned to the right. Other panels will be filled in above and below, and to the right.

Precious little information was available on how to install this product … and what there was came in Italienglish, which was little help. There was a brief on-line video, plus you could read the experiences of previous DIY clients in the customer reviews section. In such cases, you have to use the scant available information, along with your own experience, to decern an install method.

Turns out, this is similar to the old-school paper murals that come in panels and call for powdered paste. Except this company did not include paste (as most do), nor were the panels meant to be overlapped.

Luckily, I have sources for wheat, cellulose, potato starch, and other powdered wallpaper adhesives. These are mixed up on-site, are less aggressive as far as stickiness goes, and are more wet than the pre-mixed pastes used for most installations today.

More wetness, along with the particular type of paper these murals are printed on, means that the paper will absorb more moisture and can expand substantially. This is why most of these types of murals are designed to be overlapped at the seams. The seams of this product, however, were meant to be butted … which means that when that paper dries, it could shrink, and that could result in gaps at the seams.

Because the mural came in panels instead of continuous strips, the edges of the strips could not be lined up exactly perfectly, neither vertically nor horizontally. And this was exacerbated because each panel absorbed paste and expanded differently from the others, so there could be a difference in width or height between panels of as much as 1/8″.

This meant that there were some pattern mis-matches between strips. It also resulted in some seams overlapping. I left before the paper was completely dry, but I imagine there are areas where the some seams gap, too.

But I tend to overthink things, and fret about minute details that most people never see. The bottom line is, the accent wall looks fantastic, and will set a theme for the new baby’s room.

Note that this paper gets really wet when it’s pasted, and so you see a bit of blotchiness in the photos. This will disappear and the paper will be much lighter and brighter when it’s all good and dry.

The product is also not really technically a “mural.” But it comes in panels like many murals do, so I’m using that term for simplicity’s sake.

Besides the special paste, because this product was printed on a rather flimsy paper, I used a softer brush to apply the paste (as opposed to a roller), and I used a soft, long-bristled smoothing brush.
The video showed the guy using his hands to attempt to smooth the paper into place. If you looked closely, his finished wall had a lot of bubbles and wrinkles. My long soft smoothing brush was much more appropriate.

From Humid Houston to the Sunny Shores of the Mediterranean

August 22, 2018


If you’re stuck in the city but long for the warm shores of an exotic land, what do you do? How about using a scenic wallpaper mural to fool the eye into believing you’re in Paradise?

I hung this on a wall in a garage in inside-the-Loop Houston near Montrose and downtown. It will be surrounded by automobiles, bicycles, lawn equipment, and all manner of “garage stuff” – but, boy – what a view! The homeowners plan to have a big party later this year, and will use the decorated garage as an extended dining area.

This is the typical, old-school, 8-panel photo mural that has been popular for decades. After the “palm trees swaying over a tropical white sand beach” scene, Mediterranean themes like this are the most popular. But these days, you can get just about anything, even custom made from your own photos, and sized to fit your wall.

Most of these murals are 12′ wide by 9′ high, but this one was 13′ 8″ wide by 8′ 3″ high. It was smaller than the wall all-around, so I placed it more or less in the center, and also balanced on the stairs to the left (not pictured).

The mural comes in eight panels, and is hung with four panels across the top, and four across the bottom. Unlike regular wallpaper, where the seams are butted, these seams are overlapped by about 1/4″. The top photo shows just four of the panels (two top and two bottom), rolled up and laid out on the floor. It’s essential to plot and double-check like this, before you grab pieces and paste them and go to stick them to the wall.

These murals are printed on a somewhat flimsy, plain paper type material. They come with special powdered cellulose paste. I’ve always used the provided paste with these murals. But since this was going in a garage and would be exposed to heat and humidity, I wanted something a bit stronger. The instructions mentioned that, alternately, a traditional pre-mixed wallpaper adhesive could be used. So I used my go-to, Sure Stick Dynamite 780 paste.

The 780 is not as liquid as the cellulose, so it wetted-out the material differently from what I was accustomed to. It is also more aggressive, so it was a bit harder to unfold the booked sheets; too much tugging could cause the delicate paper to tear.

The cellulose paste always causes bubbling. (These disappear as the mural dries. But, still, they are unsettling.) I was happy that the pre-mixed paste did not produce any bubbles, and also allowed the paper to be more stable, with fewer wrinkles and waves. The paper did expand once it got wet with the paste, as much as a full inch per panel, so even with the 1/4″ overlap at seams, it ended up being nearly 14′ wide.

This is a paper mural, and not very durable. The homeowners plan to use a sealant, or perhaps will cover it with huge sheets of Plexiglas, to protect it. How it holds up in the humidity and heat of Houston remains to be seen. They had a similar mural (different scene) up for close to 10 years. I didn’t hang it originally, but I did some touch up and repaste a few years ago. Eventually, though, it succumbed to the elements and had to be removed. This time around, I’m hoping that my use of a wallpaper primer, along with a stronger paste, will help keep the mural nice and tight to the wall for many years to come.
