INSTALLATION
1. The utility or structural strength of the doors must not be impaired in fitting to the opening, in applying hardware, in preparing for lights, louvers, plants-on or other detailing.
2. Use a minimum of two hinges for 1-3/8" doors up to 80" in height, three hinges for all 1-3/4" doors and all doors up to 84" in height and four hinges for doors over 84" up to 96" in height.
3. Clearances between door edges and doorframe should be a minimum of 1/16" on the hinge edge. For latch edge and top rail, the clearance should be 1/8" (+0", -1/16").
4. All hardware locations, preparations for hardware and methods of hardware attachments must be appropriate for the specific door construction. Templates for specific hardware preparation are available from hardware manufacturers, NWWDA or DHI.
5. Pilot holes must be drilled for all screws that act as hardware attachments. Threaded to the head screws are preferable for fastening hardware to non-rated doors and are required on fire-rated doors.
CLEANING AND TOUCH-UP
1. Inspect all wood stile and rail doors prior to hanging them on the job. Repair noticeable marks or defects that may have occurred from improper storage and handling.
2. Field touch-up shall include the filling of exposed nail or screw holes, refinishing of raw surfaces resulting from job fitting, repair of job inflicted scratches and mars, and final cleaning of finished surfaces. Field repairs and touch-up should be the responsibility of the installing contractor.
3. When cleaning door surfaces, use a non-abrasive commercial cleaner designed for cleaning wood door or paneling surfaces that does not leave a film residue that would build up or affect the surface gloss of the door finish.
ADJUSTMENT AND MAINTENANCE
1. Ensure that all doors swing freely and do not bind in their frame. Adjust the finish hardware for proper alignment, smooth operation and proper latching without unnecessary force or excessive clearance.
2. Review with the owner/owners' representative how to periodically inspect all doors for wear, damage and natural deterioration.
3. Review with the owner/owners' representative how to periodically inspect and adjust all hardware to ensure that it continues to function as it was originally intended.
HOW TO STORE, HANDLE, FINISH, INSTALL AND MAINTAIN WOOD DOORS
Preface: Improper storage, handling, finishing and installation of wood doors may result in severe damage to the doors. The following guidelines will help maintain the high-quality products supplied by wood door manufacturers.
A. Storage and Handling
1. Store doors flat on a level surface in a dry, well-ventilated building. Doors should be kept at least 3-1/2" off the floor and should have protective coverings under the bottom door and over the top. Covering should protect doors from dirt, water and abuse, but allow for air circulation under and around the stack. Avoid exposure to direct sunlight.
2. Do not subject interior doors to extremes of heat and/or humidity. Prolonged exposure may cause damage. Buildings where humidity and temperature are controlled provide the best storage facilities (recommended conditions 30%-50% RH and 30 deg F to 90 deg F).
3. Do not install doors in buildings that have wet plaster or cement unless they have been properly finished. Do not store doors in buildings with excessive moisture content - HVAC systems should be operating and balanced.
4. Doors should always be handled with clean hands or while wearing clean gloves.
5. Doors should be lifted and carried when being moved, not dragged across one another.
B. Finishing
1. To ensure uniform moisture exposure and dimensional control, all surfaces must be treated equally.
2. Before applying first finishing coat, remove all handling marks, raised grain, scuffs, burnishes and other undesirable blemishes by block sanding all surfaces in a horizontal position with 120, 150 or 180 grit sandpaper. To avoid cross-grain scratches, sand with the grain.
3. After sanding, clean entire door with a cloth, removing all dust and foreign debris. (Avoid caustic or abrasive materials.)
4. A thinned coat of sanding sealer should be applied prior to staining to promote a uniform appearance and avoid sharp color contrasts or a blotchy appearance.
5. All exposed wood surfaces must be sealed including top and bottom rail ends. Cutouts for hardware in exterior doors must be sealed prior to installation of hardware and exposure to weather.
6. If necessary, adjust components before finishing. (Wood panels can float.) Carefully realign with a wood block and hammer.
7. Before finishing, hang the door. Then remove to finish properly. Door must be dry before finishing.
8. Certain species of wood contain chemicals that react unfavorably to some finishes or to foreign materials in the finishing system. Where possible, test your finish prior to application and eliminate the use of steel wool on bare wood, rusty containers or any other contaminate.
9. Avoid dark colored finishes if door is exposed to direct sunlight. This will reduce the chance of warping, veneer checking or sunburn.
10. Doors with clear glass require special care. Finish should flow from wood slightly onto glass to prevent water leakage and protect glazing putty.
11. Oil-based sealers or primer coats provide the best base coat for finishing. If a water-based primer is used it should be an exterior grade product. Note: Water-based coating on unfinished wood may cause veneer splits, highlight joints and raised wood grain, and therefore should be avoided. If a water-based primer is desired, please contact the finish supplier regarding the correct application and use of these products.
12. Be sure the door surface being finished is satisfactory in both smoothness and color after each coat. Allow adequate drying time between coats.
EXTERIOR FINISHING
A. Stain and Clear Finishing
1. To color and seal, make first coat a stain-and-sealer with alkyd-resin base. (Lacquer-based toner and lacquer-based finishes are not for exterior doors.)
2. Second coat may be solvent-borne (oil-base, alkyd resin-base, polyurethane resin-base) or water-borne (latex resin-base) clear finish. A marine-grade varnish is recommended on all wood exterior doors.
3. Stain-and-clear finishes perform better if protected from sunlight and weathering. (Refinishing will be required less frequently.)
B. Paint Finish
1. Seal door with a quality oil-based primer and at least two topcoats of oil-based or latex resin-based exterior paint.
2. Exterior door finishes may deteriorate with exposure to the environment. Inspect finish at least once a year. Refinish as needed.
Caution: JELD-WEN can't evaluate all available paints, stains or application requirements. Consult your paint dealer for systems best suited to your region. Select top quality finishes; follow instructions.
INTERIOR FINISHING
A. Stain and Clear Finishing
1. For interior doors, use a solvent-borne finish (lacquer-based may be used). If using a brush, preseal prior to staining. For best results, cover stains with at least two clear topcoats.
B. Paint Finish
Seal with a quality oil-based primer. Apply two topcoats of latex or solvent-based enamel.
