How to Install Wall Frames

As you put the frames on the wall, it's more important to align them relatively parallel to the elements around them—the chair rail, a wall corner, or door trim—than to check them for level or plumb. The frames go up with panel adhesive, which will hold them to the wall permanently, but quick-drying hot glue clamps them in place while the adhesive sets.

Using a caulk gun, apply panel adhesive to the four sides of the frame. Using a hot-glue gun, put a dab of glue on each corner.
