Trimming Along Bull-Nosed Edged Walls

March 10, 2020


A whole lot of new homes these days have rounded bull-nosed edges on their walls’ outside corners. These might be up to date and pleasing to the eye, but they are bugger-bears to trim wallpaper on.

For one thing, the paper is hanging over the edge, so you can’t see what you are doing or where you are trimming. Next, it’s impossible to get a correctly-positioned or straight cut – especially since you can’t see where you are cutting.

A solution to that is to use a laser level to draw a straight line that you can trim against. The problem with that is that it’s highly unlikely that the wall edge will be perfectly plumb. So if you follow a plumb laser line placed against a wall edge that is slightly off-plumb … Well, you see where we are heading.

Wallcovering Installers Association to the rescue … one of my colleagues in a distant city invented this ingenious device. It is made from the very same “bead” molding that drywall guys use when installing these walls.

I cut one to a size that’s comfortable to fit my hand. Then I cut out notches at various places. Once the gizmo is placed straddling the rounded corner, I choose the notch that corresponds to the position that I want my cut to hit.

The inventor puts a trimming knife in the notch, and then trims along the edge of the wallpaper. But I find that maneuver to be awkward. And I fear that either the gizmo or my blade will slip, resulting in a crooked cut.

So I stick a pencil point into the notch and use that to draw a line along where the cut should be made. Then I remove the guide tool and then use a straightege and razor blade to trim along my pencil line. I have the flexibility to tweak things if anything should get off-kilter.
