Finishing Introduction
HANDLING, JOB FINISHING AND INSTALLATION INSTRUCTIONS
WARNING – DOORS ARE NOT READY FOR
IMMEDIATE FINISH. ALL WOOD DOORS REQUIRE SANDING BEFORE STAINING OR PAINTING.
THE BELOW STEPS ARE NECESSARY TO ACHIEVE A HIGH-QUALITY APPEARANCE
1. Deliver doors in a clean truck
and under cover.
2. Store doors flat on a level
surface in a dry, well-ventilated building. Cover to keep clean but allow air
circulation. Avoid exposure to direct sunlight.
3. Handle with clean gloves, and
do not drag doors across one another or across other surfaces.
4. Do not deliver or install
doors until foundations, concrete floors and plaster or texture walls are
completely dry.
5. If the doors are to be stored
on the job site for more than one week, at least top and bottom edges should be
sealed.
6. Doors should not be subjected
to abnormal heat, dryness or humidity, or sudden changes therein. They should
be conditioned to average prevailing humidity of the locality before hanging.
7. Avoid placing a door too near
a heating register (at least 4 feet away). Excessive heat on one area of the
door creates drying out which results in warp, twist, shrinkage and checking on
the faces.
8. The utility or structural
strength of the door must not be impaired in the fitting of the door, the
application of hardware or cutting and altering the door for lights, panels or
any other special details.
9. Use three hinges per door on
doors 7′ 0″ in height or less, and four hinges per door on doors over 7′
0″ in height. Hinges should be set flush with edge surface. Be sure that
hinges are set in a straight line to prevent distortion. Allow approximately
3/16″ clearance for swelling of door or frame during future damp weather
periods.
10. Immediately after fitting,
cutting for closures, weather-strip and/or threshold and before hanging any
interior or exterior door on the job, the entire door, including the top and
bottom edges must receive three to five coats of paint, varnish or polyurethane
to prevent undue absorption of moisture.
11. Exterior finishes shall be
used on both faces and all edges of exterior doors. Where installed for outward
swing with no protection from the elements, doors must be properly protected by
flashing or other suitable means.
12. Before finishing, door
surfaces must be clean and dry, and moisture content is no higher than average.
Remove handling marks or effects of exposure to moisture by sanding lightly
with 120, 150, or 180 grit sandpaper with the grain, and clean with tack cloth
before applying sealer or finish. Sand and clean again between coats.
13. KNOTTY ALDER HAS
CHARACTER MARKS WHICH CONTAIN OPEN KNOTS, CHECKS AND COLOR VARIATIONS ALL
OF WHICH ARE NOT CONSIDERED DEFECTS. EXTERIOR DOORS MUST HAVE ALL VOIDS
FILLED ON THE EXTERIOR FACES. FAILURE TO DO SO WILL VOID WARRANTY.
14. DOUGLAS
FIR IS NATURALLY SAP LADEN WOOD AND MUST BE PREPARED AS FOLLOWS. WIPE ALL
SURFACES WITH ACETONE. THE PURPOSE OF ACETONE IS TO NEUTRALIZE THE SAP ON THE
SURFACES AND OPEN THE GRAIN SO IT CAN BE SEALED PROPERLY. NEXT, SAND ALL
SURFACES WITH 220 GRIT SANDPAPER, THIS WILL REMOVE ANY RAISED GRAIN.
15. Some species of wood contain
a chemical which reacts unfavorably with certain finishes. Where possible, the
surface should be tested for such unfavorable reaction. Application of a
quality sealer before finishing will promote a uniform appearance and avoid
sharp color contrasts or blotchy appearance.
16. AVOID DARK COLOR FINISHES,
if a door is exposed to direct sunlight. This will reduce the chance of
warping, checking, shrinkage and sunburn. Note sunburn in Douglas Fir will
result in pitch bleeding out onto the surface, which will not be considered a
defect. To remove bleeding pitch on surfaces, use a clean cloth in conjunction
with acetone and apply to surface areas affected. This may have to be repeated
several times throughout the year until the bleeding stops. The bleeding
generally occurs during the summer months and in most cases will not persist
after the first initial year of exposure.
17. Paint finish: Use
a good quality oil base primer, then a minimum of three brushed on or five
sprayed on coats of exterior oil base or latex base paint. If water base is
used, an oil base primer must be applied first. Finish all sides and edges of
door. Follow supplier’s instructions carefully. Failure to comply will void
warranty.
Stain finish: First apply
a clear sealer or a combination of stain and sealer. Follow with a minimum of
three brushed on or five sprayed on coats of exterior finish (such as
polyurethane or varnish) in gloss or semi-gloss. All exteriors must have ultra
violet (UV) inhibitors in the finish. Do not use oils or solid based stains as
the final finish. Both sides and all four edges of the door must be finished.
Follow supplier’s instructions carefully. Failure to comply will void warranty.
18. After the door is finished,
the panels may “breathe”, revealing a slight unfinished edge on the panel.
Minor touch-up with stain and sealer or paint is all that is needed to finish
the exposed edge. This is not to be considered a defect.
SPECIAL TIPS FOR BEST RESULTS
1. Exterior doors have a unique
problem in that they have many joints and seams; therefore, a lot of open-end
grains. If not properly treated, this could cause coating
failure due to excess moisture
intake. Additionally, the temperature difference that exists between the
interior and exterior can cause moisture transport, which may lead to problems.
Where there are holes or areas where the joinery meets, saturate heavily with
the coating and, where necessary, fill with a good quality polyurethane or
acrylic-based caulking.
2. If doors have little or no
overhang, we strongly suggest that doors be ordered with loose stop on one
side, with the solid stop side being placed to the exterior. A cap bead should
also be applied to the exterior. See page 6 for details.
3. Choice of gloss, semi-gloss or
satin clear top coats is for aesthetics. In general, semi- gloss and satin
finishes do not show flaws in the finish as readily as a gloss finish.
4. Semi-gloss and satin clear top
coats generally provide a warmer feel than does a gloss finish.
REMINDER
1. Check with your
paint supplier for the best quality products and follow suppliers instructions
carefully. Failure to comply will void warranty.
2. Exterior door finishes may
deteriorate quickly in extreme weather. Especially with little or no overhang
applications. Inspect the finishes of exterior doors regularly and refinish as
needed.
