Treatment for Warped Outside Corner

November 15, 2020

The wall to the left is behind the toilet.  You can’t see it, but there is a wall to the right of the toilet that then wraps around that outside corner you see in the center of the picture.

Wallpaper, especially a stiff non-woven material like this, does not like to wrap around corners.  Most corners are not absolutely plumb, so wrapping around them throws the paper off-plumb, or even causes wrinkles and warps.  The next strip of paper will not butt up perfectly with a warped edge.  

This corner was way worse than the typical corner, because it actually had a bow in it, so it was nowhere near straight.  There was no way that wallpaper would wrap around the corner without warping and going off-plumb

My solution was to split the paper vertically and wrap just 1″ of the paper around the corner.  Then I would cut a new strip of paper, split it vertically, making sure to match the pattern at the corner’s edge, and overlap it on top of the wrapped 1″ piece.

The only problem is that the 1″ wrapped piece had a thickness, so it would leave a visible ridge under the new strip, the entire length of the wall.

So I took some joint compound (like plaster or putty) and used a 1 1/2″ flexible putty knife to run it along the cut edge and wall, evening out that little difference in height.

Once it was dry, I sanded it smooth and primed it with Gardz.  

The ridge is gone, no bump will show, and I am ready to proceed with hanging the new strip to moving to the right.
