PF-435 - MATTE Technical Data: Prior to applying Precision Polyurethane, sand the floor according to NWFA / NOFMA specifications. Fill all cracks and holes with Precision Full Trowel Wood Filler or Precision Wood Patch. Natural finish floors should not be sanded finer than 100 grit sandpaper or screen. For stained floors, sand and edge with 100 grit sandpaper then hand sand edges using 60 to 80 grit sandpaper. Vacuum the entire floor as well as the adjoining areas. Sanded floors should be tacked with a lint-free cotton cloth dampened with mineral spirits or paint thinner. Block off any direct sources of sunlight hitting the floor. Seal the floor according to label directions using Precision Quick Dry Sealer or Precision Penetrating Stain in selected colors. Stains other than Precision stains must be tested for compatibility. DO NOT apply Precision Polyurethane over floors sealed with wax, non-drying oils, shellac or stearated sealers. TIPS: MIXING: Stir product before and, occasionally, during application. Ensure that all ingredients are completely mixed. DO NOT shake polyurethane product to avoid bubbles in finish. APPLICATION AND COVERAGE: For best results, the room and the product should be between 60ºF and 80ºF. Precision Polyurethane can be applied with a natural bristle brush, lambs wool applicator, short nap mohair roller, or a T-bar applicator at the spread rate of approximately 500 square feet per gallon. Allow to dry at least 8 hours* or overnight. When dry, abrade with a used 100 grit (or finer) screen or abrasive pad with fine sandpaper strips. Be sure to hand sand all areas not reached with machine. Vacuum floor thoroughly and tack with a lint-free cotton cloth dampened with mineral spirits. Apply the next coat of polyurethane. For high traffic areas, screen as above and apply additional coats. *Note: Low temperatures, and/or high humidity will retard drying. CLEAN UP: Clean applicators and equipment using paint thinner or mineral spirits. RECOATING EXISTING FLOORS: Clean the floor with Precision Wood / Laminate Cleaner Spray according to label instructions. DO NOT apply over floors with wax, oil, grease, shellac, or stearated sealers. Abrade old finish with 100 to 120 grit screen. Prepare and apply additional coats of Precision Polyurethane as previously instructed. PACKAGING: TECHNICAL DATA
