Today’s job was challenging and tedious, but a whole lot of fun. The homeowners worked in the oil patch, and love these seismic charts. Some show places they have worked, and one even shows the family property! They wanted the maps to cover the walls above the wainscoting in their powder room, in a large Victorian 1904 house in Montrose (Houston).
These were real maps, not wallpaper, so I had concerns about what adhesive to use, whether the material would tear when it became wet with paste, if a razor blade would cut it – or shred it, how much it would expand when wet, whether it would shrink when dry, and if ink marks on the paper (both printed and hand-written) would bleed. The homeowners provided me with a stack of maps to experiment with.
In the first photo, the maps are spread out on the dining room table, with the maps most important to them on the left, the maps with moderately significant features in the middle, and then a whole stack of maps that could be cut up to use as filler. They had worked out a few diagrams of where they wanted certain features, and also put yellow sticky paper with notations on the maps. In addition, the homeowner and I spent a lot of time talking about the various elements of the maps and what features were most important to the couple, placement, expectations, feasibility, etc.
Keeping their wants in mind, I plotted out where to place the various maps. It’s more complicated than it sounds, because they were not all the same size (in neither length nor width), the dimensions of the walls had to be taken into consideration, filler material had to be cut to bridge gaps, and “more interesting” sections had to be placed in prominent areas (the family estate went on the back wall – the first wall you see when you walk in).
Some of the maps were very similar, and I thought the walls looked better when there was something dividing the patterns, so I cut 2″ wide strips of filler (choosing material that had a contrasting pattern) to place between maps. You can see this in some of the photos. I also liked the look of a strong line at the point where two maps met, so, if the map didn’t have a printed line at the edge, I used a Sharpie to make one. This gave a lot more definition to the edges of the maps.
I learned the hard way that – regardless, of what they look like – lines on seismic maps are not straight, they are not parallel, and they are not perpendicular. Plus, you can plan on the paper stretching and warping. So, since I was starting from the chair rail and moving up, and I wanted specific things to run horizontally along the top of the chair rail (numbers, words, lines), it was really tricky to, at the same time, get a vertical line to run upwards equidistant from a vertical line on the adjoining map.
I know that sounds complicated. It was! It’s the kind of thing that takes a lot of time and plotting and measuring and trimming, but once it’s up on the wall, all you see is “a bunch of maps – that happen to look pretty straight.” The second photo shows my table with maps, homeowners’ sticky notes, my straight edge, razor blades – and me getting ready to trim!
Walls and ceilings are never plumb, and wet wallpaper likes to twist, so we paperhangers like to say that what’s at eye level is most important. Usually, I start hanging paper at the ceiling. But in this room, with it’s paneling hitting the wall at nearly 5,’ that’s pretty close to eye level, so that became the focal point. Meaning, I plotted the design at the bottom edge of the paper to line up with the top of the wainscoting.
This looks great, but it’s awkward to position, because, while gravity works with you when you are dropping a strip of wallpaper from the ceiling downward, it is definitely working against you when you are trying to work from the bottom upward. The most difficult sheets to maneuver were the largest, which were about 40″ wide by 30″ high.
I really thought that I wanted to use a wheat or cellulose paste with this material. These are both used less commonly, and come as a dry powder that needs to be mixed with water. Wheat paste is what wallpaper was hung with decades, and even hundreds, of years ago. It hydrates the paper nicely, is slippery, and does not create much tension between surfaces when you unbook the paper.
But when I did my tests, I found that my usual pre-mixed vinyl adhesive, diluted, worked very nicely. What worked best for these maps was to lightly sponge the back with water, then roll on a light coat of paste, which I diluted by sprinkling on a tiny bit more water as I spread the paste across the back.
I was pleased that the paper didn’t tear when I unbooked it (“booking” means folding the pasted sides together, and letting it sit a few minutes to relax, absorb paste, expand, etc.). But it didn’t like being unbooked and I didn’t like wrestling with it, so, except for the largest pieces, I tried to keep the paper flat and unfolded. The maps didn’t dry out like real wallpaper tends to do, so leaving it open and unbooked was not a problem.
The maps also responded quickly to the moisture of the paste – or perhaps it was the light sponging with water before pasting that helped. But I found that the material did not need to sit or book for much time at all.
This meant that I could move along a little more quickly. And it also meant that, as long as I brushed carefully and in the right directions, there were no wrinkles or bubbles. Usually I use smoothing brush with short, stiff bristles. But on this paper, a more delicate, longer bristled brush was better. I used a plastic trapezoid smoother, too, especially on the edges.
When the material was wet, it was a little difficult to trim, because it wanted to drag and tear. But a very sharp razor blade, and either a lot of pressure or a very light hand, depending on the situation, resulted in nice, clean trim lines.
I chose to overlap the seams. I wanted to avoid double cutting, because the process of double-cutting (splicing) seams can be hard on delicate paper (tears, stretching, stress on the wall). And the paper was thin enough that overlaps would not show much at all.
See that bull’s eye in the second-to-last photo? The homeowners tell me that is very exciting to oil-patch people. It designates the highest point, and thus the exact spot where oil is to be found.
Logos like that in the last photo were also important to the homeowners. I positioned some in key areas of the room. And, when I could not make that work with the walls’ dimensions, I improvised by cutting the logo off and pasting it over a different part of the map.
Although the job was tedious, in both the plotting and the installing, it went very well, and the clients were thrilled with the finished room.
