SURFACE PREPARATION
Previously Finished Surfaces – To ensure proper adhesion,
surfaces must be clean, dry, and free of wax, grease, oil, shellac,
lacquer, mildew, and polishes. Remove wax with a wax stripper,
shellac with a paint stripper, and mildew with a solution of 10%
household bleach and water. Old finishes in poor condition
should be removed. If existing finished wood surface or wood
floor is in good condition and free from wax or other
contaminates, you may recoat without totally sanding surface to
bare wood. If sanding is need, sand using 150-220 grit
sandpaper to obtain a smooth surface. Do not use steel wool as
rust may develop after the finish has been applied. Remove all
sanding dust using a vacuum, tack cloth, or cloth dampened with
mineral spirits.
Unfinished Surfaces – Sand using 150-220 grit sandpaper and
remove all sanding dust using a vacuum, tack cloth, or rag
dampened with mineral spirits. If a filler or putty is used, make
sure it does not contain wax and allow enough time for it to dry
thoroughly.
Stained or Painted Wood – Oil or water based stains can be
used prior to finish application for custom coating. Test a sample
area for product compatibility. If applying stain, it is not necessary
to use a sealer. Pro Finisher Polyurethane may be applied
directly over a thoroughly dry stain. If the use of a sealer is
desired, Pro Finisher Universal Sealer is recommended.
Sealing Surface – A sealer may be used as an option to initially
coat bare wood surface. It penetrates and seals the wood and
dries quickly. Pro Finisher Universal Sealer has excellent
adhesion and very fast dry time. Sealer must be dry before
applying finish.

..PRODUCT APPLICATION (cont.) .
WARNING! If you scrape, sand or remove old paint, you may
release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD
DUST CAN CAUSE SERIOUS ILLNESS SUCH AS BRAIN
DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN
SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-approved
respirator to control lead exposure. Clean up carefully with a
HEPA vacuum and a wet mop. Before you start, find out how to
protect yourself and your family by contacting the National Lead
Information Hotline at 1-800-424-LEAD or log on to
www.epa.gov/lead.
APPLICATION
Pro Finisher Polyurethane appears milky when wet but dries to a
crystal clear finish. Do not apply in direct sunlight. Use with
adequate ventilation at all times. Apply only when air (ambient)
temperature is between 60-80°F (16-27°C) and relative humidity
is below 85%. Use full strength. Do not thin. Stir thoroughly
before and during use. To prevent bubbles in the finish, DO NOT
SHAKE, do not over-brush, or apply with a roller.
Apply Pro Finisher Polyurethane using a synthetic or lamb’s wool
pad applicator, natural bristle brush, polyester brush, short nap
roller or a weighted T-bar. Apply in direction of wood grain in
smooth, level strokes. Apply thin, even coats at a rate of 300-400
square feet per gallon. Thicker coats will take longer to dry. Note:
A lamb’s wool applicator may apply finish heavier than
necessary. Allow product to dry 6-10 hours. Overnight dry is
preferred to produce a high quality appearance. Lower
temperatures and/or higher humidity may extend dry times.
Sanding between coats is not required for intercoat adhesion as
long as the time between coats is less than 8 hours. However,
sanding or screening between coats produces a smooth, uniform
surface. A minimum of 2 coats is recommended after the sealer
coat. Allow final coat to dry overnight before permitting light traffic
or use of surface. Finish will take up to 14 days to totally cure. Do
not place area rugs on floor and avoid exposure or washing for
approximately 1 week.
COVERAGE
Varies with surface porosity and will cover approximately 400
square feet per gallon.
CLEAN-UP
Clean application tools and equipment with mineral spirits or
paint thinner.
