Preventing White Gaps

I am about to hang a finely-textured gold grasscloth with something of a metallic sheen in the space between these bookshelves, in a home office in League City, south of Houston.

I have smoothed and primed the wall, but noticed that a little of the original painters’ white paint has wrapped just a teenie bit around and onto the navy blue walls of the bookcases. It looked fine when everything was painted and you had white wall against blue shelves. But with the gold grasscloth going next to the shelves, there was the potential for a wee little stripe of white to show between the wallpaper and the navy blue shelves.

So I got out my Box of Tricks (paint bottles) and mixed two colors together until I got a pretty good match, and then used an artist’s paintbrush from Texas Art Supply to cover up the white line where the navy blue shelf meets the white wall.

This way, you won’t have any white wall peeping out from between the new gold grasscloth and the navy blue wood.

Dark Paper + White Backing = Visible Seams

September 25, 2014

Digital ImageThis dark plum-colored wallpaper is printed on a thick and spongy, white non-woven material substrate. It’s quite likely that a white line will manifest at the seams, because that white backing just wants to peep out. Some manufacturers prevent this by printing their dark colorways on a black substrate – but I was not so lucky today.

If the white edges of the paper can be colored to match the surface, it greatly reduces the chance of the seams showing. So I made a quick run to Texas Art Supply, and picked up three different “cures” for this problem: a permanent marker, a colored pencil, and a pastel (chalk) crayon.

It’s important that these coloring devices be applied from the back of the wallpaper strip, to prevent color from seeping onto the surface of the paper, which would result in a dark line along the edge of each seam, which can be as bad as seeing a white line.

The permanent marker, which usually works nicely on paper-backed vinyl papers, did not work on the non-woven material, because it bled a little onto the surface. I thought the seam looked bad, and tore the strip off the wall. Now the stress is on, because you only have so many strips that can be wasted, until you run short of paper to finish the room.

I continued to experiment. The colored pencil, which adequately colored the edges of my test sample while I was at the art supply store, once I got back to the job site, failed to add enough color to the edges of my full-length strips of wallpaper. But the pastel did a nice job of covering up the white line, while not getting color onto the surface of the wallpaper. To make sure, I wiped the surface with my dry hand, to remove any residual pastel dust.


Of course, all this would have been unnecessary, if the company had only printed their dark pattern on a dark backing!

More on Watercoloring Seams

January 8, 2013

When I hit Texas Art Supply to buy paint to color in split seams as described below, I was careful to pick colors that matched the wallpaper as closely as possible.   The thing is, some paints dry darker than when first painted on the wall, and others dry lighter.  Here’s a good explanation of that.   And we all know that you can’t go by the paper color sample the manufacturer slaps on the top of the bottle.

In the case I talked about yesterday, although the paint in the bottle matched the paper exactly, I thought it was drying a little darker, and it was enough to show as much as the white wall showing before I started.

I couldn’t lighten the paint because I didn’t have any white paint in the truck, so I improvised by mixing some clean water into the paint.  This diluted paint was light enough to color in the seams, yet still stick to the wall.  Mission accomplished!
