Guidelines for Care of Architectural Millwork Doors
HANDLING & STORAGE OF DOORS
​
-
Upon delivery, inspect doors for any noticeable defects. Do not install or finish doors with defects.
-
Handle doors with clean hands or gloves to avoid oil stains.
-
When storing, lay flat without any twisting pressures. Protect both the top and bottom of doors with plywood or cardboard. Cover doors with plastic to protect from dust and light.
-
Do not store doors in damp areas. Storage area should be dry and well ventilated.
-
Do not store in high humidity conditions, such as freshly plastered buildings.
​​
FITTING & MACHINING OF DOORS
​
-
All machining of doors should be done before application of any sealer or finish. A door is not sealed if the installer trims the door after the painter has sealed it.
-
Excessive cutting for fitting or hardware will impair doors’ strength and life and limit warranty claims.
-
Operating door fitting clearance is 1/8” on the top, hinge side and lock side. Door bottom clearance is 3/8” to 3/4” depending on field conditions.
-
Select a fine tooth saw to avoid chipping. Ease all sharp edges with sandpaper to avoid splinters.
-
Doors between 80” and 90” should have three hinges. Use an additional hinge for every 30” of height or portion thereof. Some hollow core doors can have two hinges.
-
Exterior doors must have a projecting overhang and weather stripping for weather protection in order to be covered by this warranty.
-
Exterior doors are not intended to receive direct, sustained water.
​​
FINISHING DOORS
​
-
Check panel alignment. Panels are loose and often move during handling. If this occurs, tap into place using a soft block and hammer.
-
Sand out or fill any blemishes. Sand with grain, using 150 grit paper.
-
Clean and dust thoroughly before finishing.
​​
​
PAINT GRADE FINISH ON WOOD DOORS
​
-
Seal doors with a good quality oil-based primer and no fewer than two coats of a solvent-based or latex resin-based paint.
-
Dark exterior colors should be avoided where exposure to hot sun is expected.
-
The warranty will be voided if the two faces of the door are finished in different colors or manners.
-
Proper sanding between coats enhances the quality of the finished job.
-
When finishing glass doors, be sure to cover putty by lapping paint onto the glass to insure a weather tight seal.
​​
STAIN FINISH ON WOOD DOORS
​
-
The first coat should be a stain-and-sealer, which will both color the door and seal the surface. Use a sealer that has an alkyd-resin base.
-
The second coat may be a solvent-borne (oil-base, alkyd resin-base, polyurethane resin-base) or water-borne (latex resin-base) clear finish.
-
After sealer, finish the door with at least two coats of clear finish.
-
Semi-gloss luster gives the best appearance.
-
Proper sanding between two coats enhances the quality of the finished job.
-
It is good practice to apply stains with the door in a horizontal position. This prevents the solvents from evaporating too quickly, which is a common cause of streaks caused by stains “setting up” before clean up can be completed.
-
Stains are not water proof and should not be used on exterior doors.
​​
IMPORTANT NOTE ON FINISHING DOORS
​
-
Proper finish and maintenance will greatly add to the life of the door.
-
All surfaces must be fully painted: front, back, sides, top and bottom. The warranty is void if all six surfaces are not sealed.
