Cut potlight out too large for retrofit fixture, help?
So I made a slight mistake and cut the hole for a potlight a little larger than I should have by about 1/2" all around, so 1" diameter wider than it should have been.
This is not changeable as while it is a retrofit light, it's going inside a IC safe housing. The hole in the housing if the perfect diameter so the clamping side of the light will be within the sheet metal. I'm primarily concerned with the outer edge of the light where the retrofit light will be clamped from.
I was planning on using the setting-type 90 compound for initial fill and taping, would I just run a ring of this compound around the hole to fill it up?
The same question goes for a couple of my electrical boxes and light fixture boxes where I cut the hole maybe 1/4 to 1/2" too wide around in some cases. Mud around and it should stick?
