.DESCRIPTION AND USES .
Pro Finisher Water-based Sanding Sealer is a fast-drying, high-
performance sealer designed for use under Pro Finisher Water-
based Polyurethane where a clear, colorless finishing system is
desired. Pro Finisher Water-Base Sanding Sealer flows evenly to
fill wood pores for a smooth, sealed surface with minimal grain
raising. Pro Finisher Water-based Sanding Sealer can also be
used over a previously stained floor. Note: Pro Finisher Water-
Base Sealer will darken white oak floors. Always test on a piece
of scrap wood or in an inconspicuous area before applying to the
entire floor.

..SURFACE PREPARATION .
Surfaces must be clean, dry and free from old finish, wax, grease
and dust. To remove grease, oils or adhesive use a rag
dampened with mineral spirits. Sand area smooth beginning with
#100 grit sandpaper and progressing through #150 and #220
grits. Remove all sanding dust and dirt with a vacuum or tack
cloth. For hardwood floors, use NOFMA or NWFA accepted
methods or see Pro Finisher Professional Finishing Techniques
for sanding details. Final wipe the surface with a clean, lint free
cloth to pick up any residual dust.
Pro Finisher Water-based Sealer may raise the grain of the wood
to some extent. Smooth down raised grain using an oscillating
buffer with #120 or #150 grit screen. This will also abrade the
surface of the sealer to ensure adhesion of the finish coat. After
abrading sealer coat, thoroughly vacuum surface and then mop
with a water-dampened, lint-free cloth to pick up any residual
dust.
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

.PRODUCT APPLICATION .
Apply when air and surface temperature is between 60°F and
80°F (10°C and 27°C). Substrate moisture content should not
exceed 12%. Warmer temperatures will accelerate and colder
temperatures will prolong the dry time of this product. Do not
apply if humidity exceeds 85% or when temperature is within 10°
of the dew point.
Stir thoroughly before use and frequently during use. Do not
shake container or bubbles will form in sealer. Apply product
using synthetic pad or Universal Applicator. Apply in direction of
wood grain in smooth, level strokes at a rate of approximately
500-600 square feet per gallon. Do not over-work sealer. Coat
only a few board widths at a time, being sure to keep a wet edge.
Allow sealer to dry 1-2 hours before sanding or recoating. Note
that Pro Finisher Water-based Sealer may darken white oak
floors. Always test on a piece of scrap wood or in an
inconspicuous area before applying to the entire floor.
DRY & RECOAT TIMES
Dry and recoat times are based on 70°F and 50% relative
humidity. Lower temperatures, higher humidity and heavy or
multiple coats will prolong dry time. In most cases Pro Finisher
Water-based Sealer will dry to touch in 30-45 minutes and can
be sanded or recoated after 1 hour. Allow 24 hours for light traffic
and 7 days for full cure.
COVERAGE
One gallon of Pro Finisher Sanding Sealer will cover
approximately 550 square feet (51 m
2
) on smooth, dense woods
such as maple and 450 square feet (46 m
2
) on porous woods
such as oak. Application may vary due to the porosity of the
substrate and the method of application.
CLEAN-UP:
Clean application tools and equipment with soap and water.
