Application Directions

  • Preparation 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.
  • PREPARATION
    • Surface must be dry and free of paint, wax, grease, polish, old finishes in poor condition or any foreign matter.
    • Sand to obtain a smooth, uniform surface. Remove all dust.
    • If desired, apply stain, such as Minwax® Wood Finish™ Stain to unfinished interior wood surfaces. Follow directions for application instructions 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. Do not thin
  • APPLICATION
    • Apply a THIN coat of Minwax® Fast-Drying Polyurethane using a high-quality, natural bristle 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. 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 a second coat. If a 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 a natural bristle brush and maintain a wet edge to avoid lap marks. For maximum durability, we recommend 3 coats. Avoid heavy traffic and replacing of furniture for 72 hours after the final coat. When replacing furniture, do not slide. Do not install rugs or clean floors for 7 days.

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.
