PRODUCT APPLICATION
READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING PROJECT
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.
APPLICATION
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%. Stir contents before using and frequently during use. Do not shake container. The finish contains flattening agents that can settle and require frequent stirring during use. Use full strength. Do not thin.
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.
