Coordinate fixture attachment and electrical-box access with the fixture installer.
Finishing
Supplied primed white for finish painting. Prepare joints and fastener holes, then apply compatible finish paint following the manufacturer’s coating instructions. Coordinate exterior joints and weatherproofing with the wall assembly.
