All exposed surfaces (including the top, bottom, side edges and the hardware cutouts) must be stained and sealed no more than 30 days after installation.
- Prior to finishing, remove all debris, oils, and any other materials the unit may be exposed to during handling and installation. This is achieved by sanding the entire door with proper care by a professional to ensure no sanding marks.
- Depending on the stain material/stain manufacturer chosen, all directions must be followed including application and sanding techniques between clear coats in order to ensure proper appearance and stain coverage.
- All exposed surfaces of the door must be sealed, including the top, bottom, side edges and the hardware cutouts.
- It is imperative and will void any warranty of the door unit if a product is used that is intended for interior use and does not contain a UV inhibitor.
- Exterior surfaces, including the top, bottom and sides of the door must be finish coated with a good quality exterior grade paint or topcoat. At least three (3) coats of exterior grade topcoat with a UV inhibitor must be applied.
- Dark opaque stains as well as dark colored paints in installations with high sun exposure will not be covered under warranty as cracking, splitting, and warping are at high risk in this application.
- Most finishes on exterior doors deteriorate due to exposure to elements. To ensure exterior doors receive the protection required, inspect the condition of exterior topcoat at least once a year and recoat as often as needed to maintain the protective stability of the finish.
