DIRECTIONS FOR USE:

BEFORE USING, READ ALL DIRECTIONS AND MATERIAL SAFETY DATA SHEET # 90441 FOR SATIN AND #90401 FOR GLOSS FOR THIS PRODUCT.

DIRECTIONS FOR USE:

PREPARATION:
ABRADE AND RECOAT OLD FLOORS

1. Be sure floor is completely free of wax or oily residue. 2. Clean floor thoroughly with Bona Swedish Formula Hardwood Floor Cleaner. 3. Abrade surface with a Bona CPS4000 All Purpose Pad before finishing. 4. Vacuum thoroughly. 5. Tack with mineral spirits. 6. Apply finish (see directions).

NOTE: BONA WOODLINE POLYURETHANE 450 will adhere to most stains and finishes after proper preparation and dry times. ALWAYS PREPARE A SAMPLE OR TEST AREA TO DETERMINE COMPATIBILITY.

SANDING AND FINISHING OF NEW FLOORS:

1. Sand floor using NOFMA-accepted methods. 2. For a neutral or stained floor, make your final cut with 80-grit paper and screen with 80 - 100-grit screen. 3. For an unstained, natural floor make your final cut with a 100 - 120-grit paper and screen with 120-grit screen. 4. Vacuum thoroughly. 5. Tack with mineral spirits. 6. Apply sealer and finish system (see finish directions).

FINISHING: STIR WELL BEFORE USING!

1. BONA WOODLINE POLYURETHANE 450 is a 3-coat system. For a neutral floor begin by applying 1 coat of Bona WOODLINE 1101 SEALER or Bona WOODLINE DS-NEUTRAL STAIN according to label directions, followed by 2 coats of Bona WOODLINE POLYURETHANE 450. For a stained floor apply Bona WOODLINE DS-STAIN according to label directions, followed by 2 coats of Bona WOODLINE POLYURETHANE 450. For an unstained, natural floor apply 3 coats of Bona WOODLINE POLYURETHANE 450. 2. Apply Bona WOODLINE POLYURETHANE 450 with a lambswool applicator or brush at the coverage rate of 500 sq. ft. per gallon. Thicker application rates may adversely affect flow, leveling and drying times. Go with the grain of the wood. 3. Allow each coat to dry thoroughly (approximately 12-24 hours). Periods of high humidity and/or low temperatures will extend the drying time considerably. 4. For proper adhesion, abrade with a Bona CPS4000 All Purpose Pad between coats of finish. Allow final coat to dry a minimum of 24 hours before use and avoid heavy traffic for 72 hours.

NOTE: Bona WOODLINE POLYURETHANE 450 is not recommended over shellac, lacquer sanding sealers, fillers or stains containing stearates. Polyurethane finishes will have a slight ambering effect over light-colored surfaces.

Curing: The curing process takes approximately 14 days. The floor may be walked on after 24 hours, but the floor is susceptible to scuffing or marring prior to completion of the curing time. Do not replace athletic or walk-off mats until finish is fully cured. Cleaning with water or detergent is not allowed during the curing process.

Clean-Up: Clean application tools and equipment with mineral spirits.

Storage and Disposal: Keep container closed when not in use. Do not transfer contents to other containers for storage and disposal. Do not return used material to original container; reapply or dispose of. In case of spillage, absorb with inert material. Dispose of contaminated absorbent, container and/or unused contents in accordance with local, state and federal regulations.

DANGER: RAGS, STEEL WOOL OR WASTE SOAKED WITH BONA WOODLINE POLYURETHANE 450 MAY SPONTANEOUSLY CATCH FIRE IF IMPROPERLY DISCARDED. IMMEDIATELY AFTER EACH USE, PLACE RAGS, STEEL WOOL OR WASTE IN A SEALED, WATER-FILLED METAL CONTAINER.
