Care & Finishing
Failure to follow any portion of these instructions voids any manufacturer warranty. These instructions may be updated from time to time. The most updated version is available on Masonite.com.
HANDLING AND STORAGE 1. Do not walk on or drag doors and handle with clean gloves. 2. When products are received, they must be inspected immediately for quality, including correct size, machining, and finish (if factory finished). 3. Unfinished doors and frames must be finished within 3 days of delivery to job site with a national brand interior or exterior grade paint or stain. 4. Prior to installation, the door/unit shall be stored so that it is not exposed to the elements or allowed to sit in a damp area or standing water (must be between 25% - 55% relative humidity and 50 degrees F (10 degrees C) – 90 degrees F (32 degrees C)). 5. When storing door slabs, keep the doors stacked horizontally and fully supported on a level surface. Do not lean the doors vertically against a wall or other structure. When stacking doors, keep the top door covered at all times with a cover sheet, plywood or cardboard. 6. Masonite ships certain products with spacers. In order to prevent product distortion, it is required that the packaging spacers remain until the product is removed to be hung. 7. Pre-hung door units should be stored vertically and secured to avoid accidentally falling over. HANGING 1. Leave one-eighth of an inch (1/8”) between the door and jamb to allow for seasonal variance. 2. The maximum amount to cut off the height is one (1) inch with a maximum of:
elements as described below. Sun, rain and snow can break down the finish on your door and cause performance issues so the doors must be installed in accordance with the industry standards as shown below. Failure to follow these steps voids manufacture warranty.
a. If your door faces north or east, the minimum required overhang is equal to one half of the distance from the sill to the overhang. If your door faces south or west, the minimum overhang requirement is equal to the distance from the sill to the overhang. See illustration.
b. North or East X = ½ Y c. South or West X = Y
d. Where X is the length of the overhang required and Y is the distance from the bottom of the door to the base of the overhang.
8. Do not hang inside of a non- vented storm door as this will cause heat build- up and void the manufacturer warranty.
9. #9: Exterior doors must be installed in a location protected from exposure to direct sun or rain under normal conditions
PREPARATION FOR FINISHING 1. Machine and hang the door before finishing, assuring a proper fit. Then remove the door slab from its opening to properly finish. Finish immediately after this step. 2. Doors must be sealed prior to installation of hardware or exposure to moisture and weather. Apply finish behind hinges in bores and mortises. 3. All doors must be sanded prior to finishing. For wood grained finishes, wiping the entire door with a damp cloth prior to sanding will produce the smoothest finish. Sand the entire surface by hand using 220 grit sand paper. This is to remove handling marks, fingerprints, and residues that may prevent a satisfactory finish. Dark stains tend to magnify blemishes and variations in wood grain. If you are staining your door a dark color, extra care needs to be given during the preparation process. This may include the need to closely inspect the door for any imperfections, dirt, residue and glue. Additional sanding may be required to assure a high quality finish. 4. Clean the door thoroughly with a dry or tacky cloth to remove all dust and foreign materials. Do not use compressed air (as water may be in the lines) or abrasive or caustic cleaners on the door. 5. It is the finisher’s responsibility to assure all glass is protected prior to finishing by properly covering glass before applying paint or stain.
a. One-half (.5) inch off of the top b. One (1) inch off of the bottom 3. The maximum amount allowed for trimming the edges is one-half (.5) inch, one-quarter (.25) from either side.
4. Doors that are less than 7’ tall must have three (3) hinges. Doors above 7’ tall must have four (4) hinges and a multi-point locking system is recommended. 5. Screw holes must be pre-drilled to prevent splitting and stripping. 6. All drill bits and blades must be sharp to prevent splitting and cracking. 7. Unless a Torrefied species is chosen, all Masonite Exterior Wood doors must be protected from the
