COMPATIBILITY: Bona All Court® is not recommended over shellac, lacquer sanding sealers, fillers or stains containing stearates. Oil modified finishes will have a slight ambering effect over light colored surfaces. Bona All Court will adhere to most finishes after proper preparation and dry times. ALWAYS PREPARE A SAMPLE OR TEST AREA TO DETERMINE COMPATIBILITY, APPEARANCE AND DESIRED RESULTS.
SANDING AND FINISHING NEW FLOORS: 1. Sand and prepare floor using MFMA-accepted methods.. 2. Make your final cut with 100-120-grit paper. Screen with 100-120-grit screen. 3. Vacuum thoroughly. 4. Tack with mineral spirits. 5. Apply sealer and finish system (see finish directions).
THE BONA COURTLINES® PAINT SYSTEM: Bona All Court is a 4-coat system, 1-2 coats of a Bona oil- modified sport sealer, CourtLines paint (if desired) and 2-3 coats of Bona All Court.
MIXING INSTRUCTIONS: Remove lid and stir thoroughly before using. DO NOT THIN.
FINISHING: 1. Apply Bona ALL COURT with a heavy weight T-bar applicator. Go with the grain of the wood applying a thin, uniform coat. 2. BE SURE YOU ARE USING THE RECOMMENDED COVERAGE OF 600 SQ FT PER GALLON. 3. Avoid leaving puddles of excessive amounts of finish on the floor. 4. Allow first coat to dry thoroughly (approximately 8-12 hours). High humidity and/or low temperature conditions will extend dry time while increased ventilation and airflow will reduce dry time (recommended conditions of 65-80°F (18°-27° C)/40-60% relative humidity). 5. For proper adhesion, abrade between coats of finish. Allow final coat to dry a minimum of 72 hours before use.
