There's quite a few of these on my daughter's new build. They deliberated over chiselling
a flat on the wall. But decided against it. Now looking for options to hide the messy sealant...was thinking of mounting a shadow plate behind the main body of the lamp, around the square section. Like an "n" shape dropping in from the top and pu adhesive to the back, top, of the lamp body. Maybe 40mm projection either side, so the messy sealant is behind it and in the shadow, could use aluminium or stainless, powder coated to match the lamp.Any other ideas?
