WARNING! Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead. Exposure to lead dust or fumes may cause brain damage or other adverse health effects, especially in children or pregnant women. Controlling exposure to lead or other hazardous substances requires the use of proper protective equipment such as a properly fitted respirator (NIOSH approved) and proper containment and cleanup. For more information, call the National Lead Information Center at 1-800-424-LEAD (in US) or contact your local health authority.
- Surface must be dry and free of old finishes in poor condition, paint, wax, grease, polish, dirt or other foreign matter.
- Sand to obtain a smooth uniform surface. Remove all dust with a cloth dampened with mineral spirits.
- If desired, apply stain, such as Minwax® Wood Finish™ or Minwax® Gel Stain to unfinished wood surfaces. Follow directions for application and dry times.
- Stir Minwax® Fast-Drying Polyurethane before and during use to eliminate settling on the bottom of the can. Stir to rotate the product from the bottom to the top of the can. NEVER SHAKE.
- Apply a THIN coat of Minwax® Fast-Drying Polyurethane using a high-quality natural or foam brush.
- For floor projects, use a square buff orbital or disk-type sander with 220 grit sandpaper or the equivalent grit pad or screen (specifically designed for sanding between coats). Do not use a belt or drum-type sander for sanding between coats. Follow the sander manufacturer’s directions for your type of project.
- Apply second coat. If third coat is desired, repeat step 6 before application.
- After final coat, allow 24 hours before light use.
When used on hardwood floors, use a lambswool or synthetic pad applicator or natural bristle brush and maintain a wet edge to avoid lap marks. For maximum durability, we recommend three coats. Avoid heavy traffic and replacing of furniture for 72 hours after final coat. When replacing furniture, do not slide. Do not install rugs or clean floors for 7 days.
CLEANUP: Use mineral spirits or paint thinner following manufacturer’s safety instructions.
COVERAGE: Approximately 125 square feet per quart.
Note: Above dry times are based on good ventilation, temperature of 77°F and 50% relative humidity. Lower temperature, higher humidity, lack of air movement or application of thick coats will extend drying times. Always test tackiness between coats. Do not sand or re-coat when surface is tacky. Slight ambering may be experienced when Polyurethane is applied over light-colored wood surfaces. Always spot test on an inconspicuous area to ensure satisfactory results. For light-colored wood surfaces, we recommend protecting with Minwax® Polycrylic® Protective Finish or Minwax® Ultimate Floor Finish.
DANGER: Rags, steel wool, other waste soaked with this product, and sanding residue may spontaneously catch fire if improperly discarded. Immediately place rags, steel wool, other waste soaked with this product, and sanding residue in a sealed, water-filled, metal container. Dispose of in accordance with local fire regulations.
CAUTIONS: CONTAINS ALIPHATIC HYDROCARBONS.
Contents are COMBUSTIBLE. Keep away from heat and open flame.
VAPOR HARMFUL. Use only with adequate ventilation. To avoid overexposure, open windows and doors or use other means to ensure fresh air entry during application and drying. If you experience eye watering, headaches, or dizziness, increase fresh air, or wear respiratory protection (NIOSH approved) or leave the area. Avoid contact with eyes and skin. Wash hands after using. Keep container closed when not in use. Do not transfer contents to other containers for storage.
FIRST AID: In case of eye contact, flush thoroughly with large amounts of water for 15 minutes and get medical attention. For skin contact, wash thoroughly with soap and water. In case of respiratory difficulty, provide fresh air and call physician. If swallowed, call Poison Control Center, hospital emergency room, or physician immediately.|

- The surface must be dry and free of old finishes in poor condition, paint, wax, grease, polish, dirt or other foreign matter.
- Sand to obtain a smooth, uniform surface. Remove all dust.
- If desired, apply stain, such as Minwax® Wood Finish™ Stain, to unfinished wood surfaces. Follow directions for application instructions and dry times.
- Shake Minwax® Fast-Drying Polyurethane vigorously for two minutes. Shake for 10 seconds occasionally during use.
- Protect adjacent areas from overspray. Wet overspray can be removed with mineral sprits.
- Hold can vertically 12 inches from surface. Depress button fully and spray using an even, sweeping motion with slightly overlapping strokes. On unfinished wood, apply sufficient material to seal open joints, edges and end-grain.
- Apply thin coats to avoid runs and sags. Recoat within 2 hours. If unable to do so, wait a minimum of 72 hours, then lightly sand and recoat.
- Apply at least three coats on unfinished wood and two coats on surfaces already finished.
- After final coat, allow 24 hours before normal use.
Note: Above dry times are based on good ventilation, temperature of 77°F and 50% relative humidity. Lower temperature, higher humidity, lack of air movement or application of thick coats will extend drying times. Slight ambering may be experienced when Polyurethane is applied over light-colored wood surfaces. Always spot test on an inconspicuous area to ensure satisfactory results. Minwax® Polycrylic® Protective Finish is recommended over light-colored wood surfaces.
- After each use, clear valve by holding can upside down and spraying until only clear gas comes out.
- If spray button becomes clogged, wear eye protection, wipe off button opening with lacquer thinner- Do NOT stick pin in spray button opening.
Frequently Asked Questions
What is the best way to select a sheen?
Sheen choice is a personal preference. Satin sheens reflect less light and gloss sheens reflect more light.
Is one sheen more durable than the others?
No. The additives that distinguish satin from semi-gloss and gloss do not compromise the durability of the finish.
What can be done to avoid bubbles in the finish?
There are four ways. First, stir, don't shake, the can. Second, use a high-quality, natural bristle brush. Third, work the finish into the wood, but don't create excess foam. Fourth, "tip-off" the finish before stopping, carefully running the brush at a 45-degree angle the length of each board in one unbroken movement. This will burst and smooth out any bubbles that may have been created.
Should Minwax® Fast-Drying Polyurethane be sanded between coats?
Yes. A light sanding (#220 sandpaper) will remove any fine particles of dust that have settled on the finish while it was still wet. Light sanding also helps abrade the surface, improving intercoat adhesion.
Why does Minwax® Fast-Drying Polyurethane sometimes take longer to dry than the instructions indicate?
The drying time is affected by the amount of moisture in the air, the air temperature and the thickness of the coats. When humidity is high, temperature is low, or coats are thick, it takes longer for the film to dry.
What is the best way to determine how many coats of Minwax® Fast-Drying Polyurethane to apply?
If you look closely at the wood in bright, direct light, you should not be able to detect any dry spots. If you do, an additional coat is necessary to protect the wood.
Does Minwax® Fast-Drying Polyurethane need to be waxed?
No. Wax does provide an extra layer of protection, but it will prevent you from applying an additional coat of Minwax® Fast-Drying Polyurethane in the future without first removing the wax. Instead, we recommend using Minwax® Wood Cabinet Cleaner to keep wood clean and looking beautiful.

Prevent Bubbles in the Finish
To minimize brush marks and bubbles, "tip off" each section of your project. Hold the brush at a 45-degree angle and lightly run the bristles over the entire length of the wood.
