DESCRIPTION AND USES
Pro Finisher Water-Base Polyurethane is a durable clear finish designed for coating and protecting hardwood floors and other interior wood surfaces.

PRODUCT APPLICATION
SURFACE PREPARATION
Surfaces must be clean, dry, and free of wax, grease, oil, shellac, lacquer, mildew, and polishes.
SANDING SURFACE: Sand area smooth, progressing in sandpaper grit from rough to medium to fine. For hardwood floors, use NOFMA and NHFA accepted methods or see Pro Finisher Professional Finishing Techniques for sanding details. After sanding vacuum surface and wipe with a cloth to remove all dust.
STAINING SURFACE: Oil or water based stains can be used on bare wood surface prior to sealer or finish application. Allow oil based stains a minimum of 72 hours dry time before sealer or finish application. If using water based stains follow stain manufacturers dry time directions.
SEALING SURFACE: A sanding sealer may be used to initially coat bare wood surface. Pro Finisher Water Base Sealer or Pro Finisher Universal Sealer is recommended. Pro Finisher Water Based Sanding Sealer will produce a colorless finish. Pro Finisher Universal Sealer will add a rich tone to the wood (similar to traditional oil based finish).
Sealer must be dry and lightly abraded prior to applying a finish.
Note: Water based sealer will darken white oak. To maintain clear color apply Pro Finisher Water Based Polyurethane directly over bare wood.
APPLICATION
Pro Finisher Water-Base 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.
Apply Pro Finisher Water-Base Polyurethane using a Pro Finisher Universal Applicator, Lambswool applicator pad, polyester brush, or a weighted T-bar. Apply in direction of wood grain in a pulling motion with smooth, level strokes. Apply thin, even coats at a rate of 600-700 square feet per gallon.
Allow product to dry a minimum of 1-2 hours between coats. Sanding between coats is not required for adhesion as long as the time between coats is less than 6 hours. However, screening or sanding between coats usually produces a smoother better looking finish. A minimum of 3 coats of finish are recommended. Do not apply more than two coats the same day.
Sand between coats with 120-150 grit sandpaper or maroon abrasive pad. After sanding vacuum surface and wipe clean with a lightly water dampened lint free cloth to remove all dust before applying the next coat.
DRY TIME
Dry times are based on 70°F and 50% relative humidity. Pro Finisher Water Base Polyurethane dries to the touch in 1-2 hours and is suitable for foot traffic in 24 hours.
CLEAN-UP
Clean application tools and equipment with soap and water.
