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 old finishes in poor condition, paint, wax, grease, polish, dirt or other foreign matter.
    • Sand to obtain a smooth, uniform surface. Do not use steel wool. Remove all dust with a damp cloth.
    • If desired, apply stain, such as Minwax® Wood Finish™ Stain or Minwax® Gel Stain to unfinished wood surfaces. Follow directions for application instructions and dry times. Wait 8 hours after staining, before applying Oil-Modified Polyurethane.
    • Stir Oil-Modified 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.
  • APPLICATION
    • Apply a THIN coat of Oil-Modified Polyurethane using a high-quality synthetic bristle or foam brush.
    • Let dry 2 hours. Then lightly sand entire surface with fine sandpaper (220 grit) to ensure an even finish and proper adhesion. Remove all dust.
    • Apply a second coat. Oil-Modified Polyurethane requires a third coat; 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 synthetic bristle brush and maintain a wet edge to avoid lap marks. For maximum durability, 3 coats are required. 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.

WHERE CAN I USE WATER BASED OIL-MODIFIED POLYURETHANE?

Water Based Oil-Modified Polyurethane is ideal for use on all interior bare or stained wood surfaces including furniture, cabinets, doors and floors. It can be applied over oil-based stains like Minwax® Wood Finish™ or Minwax® Gel Stain. It also can be applied over Minwax® Water Based Wood Stain wood tones, provided the stain has dried completely.

CAN I MIX MINWAX® WATER BASED OIL-MODIFIED POLYURETHANE WITH MINWAX® FAST-DRYING POLYURETHANE?

No. The oil-based and water-based products are not compatible and they should not be mixed together. However, the results are the same—a beautiful, durable finish!

CAN I APPLY WATER BASED OIL-MODIFIED POLYURETHANE OVER FAST-DRYING POLYURETHANE OR VICE VERSA?

Yes. The two products can be applied over each other as long as the first has fully cured. Follow the directions for the product you are using. Be sure to apply each coat with only one product. Do not finish part of a surface with one topcoat and part with the other as this could result in a uneven appearance across the surface of the wood.
