     All Wood Doors by Lag Design®

•  Do not walk on any door units. Some units contain glass.
•  Avoid dragging doors across one another and keep doors clean.
•  Store flat on a level surface in a dry, well ventilated building.
•  Doors should be conditioned to average prevailing relative humidity of the locality before hanging.
•  Doors should be delivered to the building site only after the concrete, plaster, stucco, sheet rock work and paint are completely dry.
•  Doors should not be subject to extreme or rapid changes in heat or humidity. Avoid sudden changes such as forced heat to dry out a building.
  If the doors are to be stored on the job site, all ends and edges must be sealed with an effective quality oil-base sealer in order to prevent undue moisture absorption.
1.  Doors should always be stored flat and in clean, dry surroundings. Cover the pallets with plastic to protect from dirt, water, and abuse. If stored for long periods, doors should be sealed with a non-water based sealer or primer unless they are individually wrapped.
2.  Doors should not be exposed to excessive moisture, heat, dryness, or direct sunlight.
3.  Doors should always be handled with clean hands or while wearing clean gloves.
4.  Doors should be lifted and carried, not dragged across one another.
Finishing Options
Because LAG DESIGN® doors are crafted with only the finest materials, you can choose from a wide variety of stain or paint possibilities. Paint dealers have a broad selection of color chips on hand to demonstrate the look you can achieve when finishing LAG DESIGN® doors.
If you choose paint instead of stain, you can apply either oil-base or latex resin-base paints over an oil-base primer.
Latex/water base primer may contribute to raised grain. Take care in following the finishing instructions provided. Also, be sure to evaluate the conditions your door must endure, such as direct exposure to severe climates, before deciding on the specific finish to use.
Preparation for Finishing
•  Before applying the first coat of finish, sand the entire surface with 5/0 sandpaper (180 grit). This is to remove fingerprints, handling marks, any raised grain and will help insure a more uniform finish.
•  Adjust or align components if necessary before finishing. Wood panels and other components “float” and may be moved if necessary. Be careful not to damage the door.
•  Clean door thoroughly after sanding with a cloth to remove all dust or foreign material. Avoid using compressed air to blow off door as moisture or oil in air will cause spotting. Avoid using caustic or abrasive cleaners.
•  Hang door before finishing. Then remove to finish properly.
•  When staining, a wood conditioner may be used to help achieve a more uniform finish. (Be sure to follow manufacturer’s instructions closely.)
•  All surfaces of the door must be properly finished. The edges (top, bottom and sides) should be coated with each and every coat of finish that is applied to the faces of the door.
Exterior Finishing
1.  Stain-and-Clear Finish
When staining, a wood conditioner may be used to help achieve a more uniform finish. (Be sure to follow manufacturer’s instructions closely.) The first coat of stain may be a combination of stain and sealer which colors the door and seals the surface. It is available in a wide range of colors. The stain-and-sealer should have an alkyd-resin base. Under no circumstances should a lacquer-based toner or any other lacquer-based finish be used on exterior doors.
  The second and third coat (two top coats minimum) may be a solvent-borne (oil-base, alkyd resin-base, polyurethane resin-base) or a water-borne (latex resin-base) clear finish. On doors that are glazed, the finish used should be flowed from the wood slightly onto the glass. This will provide assurance against water leakage and protect the glazing compound from drying out.
The advantages and disadvantages of solvent-borne vs. water-borne clear finishes are as follows:
Solvent-Borne Advantages:
Faster drying, harder and more water
resistant. May be applied under
variable weather conditions.
Subject to ultra-violet degradation and not as flexible or durable as water-borne clear finish.
Water-Borne Advantages:
Very flexible, greater ultra-violet resistance, and good exterior durability.
Cannot be applied below 50°F, long drying period required, and may not fully cure for several weeks, Water-sensitive until cure is complete. Note: Do not sand between coats of latex clear.
All stain-and-clear finishes will perform measurably better if protected from the direct effects of sunlight and weathering, and refinishing will not be required as frequently.
2.  Paint Finish
Either oil-base or latex resin-base exterior grade paints may be used with success on doors. Oil-base paints offer more resistance to the passage of water (liquid and vapor) than latex resin-base paints, but the latter have better durability and color retention.
Doors should be sealed with a good quality oil-base primer followed by two top coats of either an oil-base or latex resin-base paint. Of course, both primer and top coat should be made by the same manufacturer and be designed to be used as a combination.
Note: Where possible exposure to direct sun or rain is a factor, doors should be sealed with a premium quality oil-base primer followed by two top coats of a premium quality oil-base paint.
3.  Caution
LAG DESIGN® cannot evaluate all the available paints and stains, nor the customers’ specific application requirements. Your paint dealer should know of suitable finish systems that give satisfactory results in your region. It is highly recommended that top quality finishes be selected, and the application instructions on the container be followed explicitly.
Interior Finishing
1.  Stain-and-Clear Finish
When staining, a wood conditioner may be used to help achieve a more uniform finish. (Be sure to follow manufacturer’s instructions closely.) A solvent-borne finish system is recommended for interior doors and may be a lacquer-based system. For best performance, a minimum of two clear top coats should be used over stains.
2.  Paint Finish
  Doors should be sealed with a good quality oil-base primer followed by two top coats of a solvent-base or latex enamel.
Fitting and Hanging
•  When hanging door, allow adequate clearance for swelling of door or frame in damp weather. Allow approximately 3⁄16" clearance for swelling when the door is installed in fully dry conditions. Jambs must be plumb.
•  Trimming and beveling for custom fitting is possible on all four edges of the standard door. Each door may be trimmed up to 31⁄2" from the bottom, 1⁄2" from each side and 11⁄4" from the top.
•  Caution must be used to avoid impairing the strength of the door when fitting for locks. Allow at least 1"of wood back of mortise.
•  Use three hinges on doors up to 7' in height and four hinges on doors over 7'. Hinges must be set in a straight line to prevent distortion.
•  Jambs and stops must be set square and plumb.
•  For best performance, any exterior door should be installed under an overhang or with protection. If an overhang is not feasible, finishing the door in a light color may help prevent excess heat build-up in the door.
•  Immediately after cutting and fitting (before hanging), seal all cut surfaces and ends of door with an effective quality sealer. See exterior and interior finishing recommendation for complete instructions.
•  Prior to exterior exposure, doors should be finished with complete finish system.
•  To minimize heat loss and save energy, use weather stripping.
Field Finishing
1.  Inspect your door(s) immediately and notify your dealer or LAG DESIGN® if there are any problems. Do not cut, trim or finish the door before careful inspection. Once the door has been altered in any way, it cannot be returned to the manufacturer for replacement unless defects occur that are covered by warranty.
2.  Prior to finishing, insure that the building atmosphere is dried to a normal, interior relative humidity. Insure that the doors have been allowed to equalize to a stable moisture content.
3.  Remove all handling marks, raised grain, glue smears and other undesirable blemishes by completely block sanding (with the grain) all surfaces with a 100 to 150 fine grit abrasive.
4.  Seal the door on all six sides immediately after removal from the plastic wrap.
5.  Water-based sealer or prime coats should be avoided. Water-based top coats should only be used over surfaces that have been completely sealed. Defects caused by failure to seal all six sides of the door will void its warranty.
6.  A first coat of a thinned clear sanding sealer followed by light block sanding, will minimize subsequent handling marks and promote the uniformity of subsequent stain coats.
7.  Some species react unfavorably with certain finishes causing dark stain spots (blotching). Where possible, the species/finish combination should be tested prior to finishing the doors. Notify your finish supplier or door supplier immediately if any undesirable reaction is noticed. Do not finish the door until the problem is resolved.
8.  In order to prevent blemish magnification, avoid dark stains, especially in Maple and Pine where we recommend only clear coating whenever possible.
9.  Follow finish manufacturer’s recommendations carefully to achieve the desired results on the following: color uniformity, finish build, gloss, and to reduce the frequency of refinishing.
10.  Be sure the door surface being finished is satisfactory in both smoothness and color after each coat before applying the next coat.
1.  The structural strength of the doors must not be impaired in fitting to the opening or in applying hardware.
2.  Use a minimum of one hinge for each 30" of door height on all LAG DESIGN® doors. When using three or more hinges, they are to be equally spaced.
3.  Allow adequate clearances between door edges and door frame for swelling.
4.  All hardware locations, preparations for hardware, and methods of hardware attachment must be appropriate for the specific door construction.
Your LAG DESIGN® door has been handcrafted to last for years to come. But, like any fine piece of furniture, its finish will require some simple, periodic maintenance to keep it looking great and provide proper protection against the elements. Regular finish maintenance is also a requirement of the warranty that’s included with every door.

Here are some signs to watch for that indicate it’s time for some simple, easy-to-perform maintenance:
1.  Hairline cracks in the top coat of finish.
2.  Changes in the color of the finish.
3.  Changes in the texture of the finish, such as flaking or scaling.
4.  Dullness or chalkiness in the finish.
If you live in a severe climate or your entry receives a lot of direct sunlight from a southern or western exposure, you’ll want to examine your door’s finish often.
Finishes on interior doors last for many years. However, inspect the condition of the finish at least once a year and refinish as often as needed to maintain the protective integrity of the finish.
Depending on the conditions, you may also need to refinish the door more frequently.
Insure that doors swing freely, do not bind in the frame, and that all hardware remains functional.
