- 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™ 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.
- Let dry 4-6 hours. Then lightly sand entire surface with fine sandpaper (220 grit) to ensure an even finish and proper adhesion. Remove all dust.
- 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 14m2 per 946ml
Note: Above dry times are based on good ventilation, temperature of 25°C 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-coloured wood surfaces. Always spot test on an inconspicuous area to ensure satisfactory results. For light-coloured wood surfaces, we recommend protecting with Minwax™ Polycrylic™ Protective Finish.
- 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 30cm 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 25°C 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-coloured wood surfaces. Always spot test on an inconspicuous area to ensure satisfactory results. Minwax™ Polycrylic™ Protective Finish is recommended over light-coloured 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.
CLEANUP: For easy clean-up, use lacquer thinner following the manufacturer's safety instructions.
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.
