Apply either oil-base or latex resin-base
paints over an oil-base primer. (Latex or
water base primer may contribute to raised
grain). Take care in following the finishing
instructions provided. Be sure to evaluate
the conditions your Woodgrain door must
endure, such as direct exposure to severe
climates, before deciding on the specific
finish to use.
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. See note (1) and (2) below.
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.
Solvent-Borne Disadvantages: 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.
Water-Borne Disadvantages: Cannot be applied below
50º F, long drying period required, and may
not fully cure for several weeks. Watersensitive
until cure is complete. Note: Do
not sand between coats of latex clear.
All stain-and-clear finishes will perform better if protected from the direct effects of sunlight and weathering, and refinishing will not be required as frequently. www.woodgraindoors.com 34 35 www.woodgraindoors.com
2. Paint Finish
Either oil-base or latex resin-base exterior grade paints may be used. Oil-base paints offer more resistance to the passage of water (liquid and vapor) than latex resin-base paints. Latex resin base paints have better durability and color retention.
Doors should be sealed with a good quality oil-base primer followed by two topcoats of either an oil-base or latex resin-base paint. 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
Woodgrain Doors 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.
Please do not use metal objects, (razor blades etc.) to remove caulking compound or paint and varnish residue, it is known to scratch the tempered glass. Please do not use compressed air to blow off wood doors, as condensation in the air lines may cause irregular finishing results.
Interior Finishing1. Stain -and-Clear Finish
When staining, a wood conditioner may be used to help achieve a more uniform finish. (Be sure to follow wood conditioner manufacturer’s instructions closely.) A solventborne 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.
