Crown Molding Insulation

Crown Molding will need to be sealed on all sides. 2 coats of oil base primer is recommended and 2 latex finish coats after insulation.Caulking the molding to the wall and ceiling will make your work look clean and sharp tape off the wall and ceiling allowing a 1/16 of an inch between the tape and crown.Before you caulk then pull the tape off as soon as your second finish coat is on. Learn to Cope your crown will give you a much better job after insulation.Adding a block of wood and gluing to the back of your joints on long runs will keep your joints from separating.
