Preparation for Finishing
• When staining , a wood conditioner or sander / sealer must be used to achieve a more uniform finish . ( Be sure to follow the wood conditioner manufacturer ’ s instructions closely .)
• Fir doors should be surface treated with acetone product in advance of wood conditioner .
• Before applying the first coat of finish , thoroughly sand the entire surface of the door with 180 grit sandpaper . This crucial step helps remove handling marks , fingerprints , fiber pop , natural grain raise , possible water or liquid marks ( if exposed during shipping or while on the job-site during the construction phase ) and evenly prepares open wood pores to help produce a more uniform finish .
• Panels and TDL bars float and may become out of alignment during shipping and handling . Carefully take a block of wood and mallet and tap the components in alignment . Use caution not to damage the door or components during this process .
• Clean the door thoroughly with a cloth after sanding to remove all dust or foreign material . Avoid using compressed air to blow off the door as moisture or oil in the air may cause spotting . Avoid using caustic or abrasive cleaners .
• Hang the door before finishing it , then remove it to finish properly . Doors stored in stable climate controlled area and should be finished within 72 hours on home site
Exterior Finishing
Stain-and-Clear Finish
When staining , a wood conditioner must be used to achieve a more uniform finish . ( Be sure to follow the wood conditioner manufacturer ’ s instructions closely .) The first coat of stain may be a stain-and-sealer , a combination of stain and sealer which colors the door and seals the surface . It is available in a wide range of colors . ( Dark color finishes should not be used on doors exposed to prolonged direct sunlight , as some expansion and contraction of door parts may occur . See warranty for detail .) 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 coats ( 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 flow from the wood slightly onto the glass . This will provide assurance against water leakage and protect the glazing compound from drying out .
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 . In areas of high exposure to sunlight and weather , a marine grade top coat is recommended .
Interior Finishing
Stain-and-Clear Finish
When staining , a wood conditioner must be used to achieve a more uniform finish . ( Be sure to follow the wood conditioner 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 . All six sides of the door must be properly sealed for the warranty to apply . Woodgrain Doors have plastic film protection on the glass , removal of plastic film protection immediately after applying the finish is required . Failure to remove the plastic film at this time may cause harm to the glass and will create difficulty in removing the film at a later time . Do not use razor blades or sharp objects to remove the film or clean the glass . These items will scratch the glass .
Painted Finish
Apply 2-3 coats of either oil-base or latex resin-base paints over 1-2 coats of an oil-base primer . PRM with MDF veneer & panels or MDF router carved recommend for ANY painted door application . ( Latex or
