Use And Care Manual
Preparation
Do not sand with sandpaper! If required, use #000 steel wool 
with very light pressure (weight of hand) to smooth surfaces. 
Clean up after the steel wool with a tack cloth. Then clean 
panels and sidelites by wiping with mild detergent and water. 
Rinse thoroughly, and allow to dry completely before painting 
or staining.
Use only high-quality stain. Gelled stains work best. Artist 
oils or highly pigmented non-penetrating oil-base stains can 
also be used. Gelled stains and artist oils have better application 
and working time when mixed with mineral spirits. Follow 
stain manufacturer’s instructions for best results. 
Materials Needed
•  Mineral Spirits
•  China Bristle Brushes (several)
•  Clean, Lint-Free, Cloths
•  Spar- Marine Varnish
•  Protective Gloves
•  Stir Sticks
•  Gel Stain
Read and follow all warnings, cautions and 
manufacturer’s instructions on the products 
you will be using.
IMPORTANT!
  Do not sand door or sidelite surfaces. 
  Do not use acetone or lacquer thinner. 
  Do not apply stain in direct sunlight.
Proceed as follows:
1.  Remove door panel and place it on a padded sawhorse 
or other padded surface, being careful not to mar the 
back side. 
2.  Remove all hardware from areas that will be finished.
3.  Apply a liberal coat of stain with a cloth. Work the stain 
across and into the grain. While stain is still wet, use a brush 
and long light strokes (with the grain) to feather-out stain 
for a uniform appearance. As you work remove excess 
stain from the brush with a clean cloth. Apply stain until the 
desired color is achieved.
4.  Start staining with the raised panels labeled A in FIG. 1. 
Next stain and feather the rails, item B. Then do the stiles, 
item (C).
FIG. 1 depicts a typical door 
panel. Your model may vary.

5.  Lastly, stain the door panel edges feathering with long 
brush strokes for best appearance.
6.  Use this same technique and sequence to complete 
sidelite(s) and transom options.
7.  Allow stain to dry completely before handling panel.
Hint - Color can be intensified by applying a second coat of 
stain after the first coat has completely dried and before 
applying the spar-marine varnish. To check suitability, 
perform a test application where it won’t be noticed.
8.  Top Coating: For best results, use 2 or 3 coats of Spar-
Marine varnish. Be sure to seal the top, bottom, and edges 
of the door panel. Follow the manufacturer’s instructions 
for drying time and finishing procedures.
Reapplying Top Coating
For best results, apply annual coats of spar varnish following 
manufacturer’s instructions. Re appli cation may be required 
every year. Direct sunlight and moisture will cause the finish to 
degrade faster than in an unexposed environment.
