• Masking tape
• 2" bristle brush
• Gel stain (use a top quality exterior gel stain)
Madero’s stain kit includes all of the required

CLEANING & PREPARATION
Choose an area that is dust free, well ventilated
and has adequate lighting. It is important
that the temperature be within the stain
manufacturer’s recommendations.
1. Place the door flat on padded saw horses or
other supports.
2. Trim or scrape any factory sealant that has
seeped out from seams or window trim.
3. Mask off any areas not to be stained, including
glass and the door jamb.
4. Wipe the door thoroughly with a cleaning
solvent, mineral spirits or an all purpose
cleaner and allow to dry.
2. “Pull” the stain with a clean lint-free rag or
cheese cloth by gently rubbing with varying
pressures in the direction of the grain. This will
help accentuate the grain pattern in the door
or component.
3. While the stain is still wet, gently go over the
doors with the 3” bristle brush to remove any
streaks or lap marks. The brush can be dabbed
in corners and crevices where there is heavy
stain accumulation. Keep the brush clean
during this process by using a rag to remove
stain from the bristles.
4. As recommended, the first stain application
should be applied in a light coat. If a darker
colour is desired, wait a minimum of 8-12
hours for the stain to dry before applying a
second coat.

STAINING
Stir the stain thoroughly to ensure proper
product colour and consistency. It may be
beneficial to practice staining a small area of the
door. This will allow familiarity with the process
and ensure shade and colour accuracy. The
practice area can be cleaned with solvent prior
to staining the door. For best results, adhere to
the following steps:

SEALING / PROTECTING
Depending on conditions, wait at least 8 to
24 hours (possibly longer) to allow the
stain to dry properly before applying the
Spar-Marine Varnish.
1. Using a 3” bristle brush, apply the varnish
in the direction of the grain in the same
panel sequence as used in the stain
application.
NORMAL MAINTENANCE
By exposure and weathering from sun,
moisture and air pollutants, a well finished
exterior fiberglass door will be affected.
Normal maintenance is to reapply the
topcoat approximately every two years.
2. A minimum of 2 coats is recommended,
allowing 6 hours drying time between
coats. Brushes can be kept clean with
solvent or mineral spirits.
