The Chamfer molding is used to terminate your porch board around the perimeter of your porch. This product was engineered to cover the exposed ends of the T&G boards. There is no need to cover the ends of the T&G boards, it is purely preferential. By using the Chamfer molding you will crate a perfect edge for your porch that matches most every architectural style.
The Chamfer molding should be glued with the Oatey PVC heavy duty PVC cement and the a trim head screw should be used every 16″. The screw holes can be filled with the DAP blend stick or a colored matching caulk. See Installation Resources for a listing of all products used to install and complete your Aeratis installation.
