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 hazerdous 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.

Special Instructions: Minwax® One Coat Polyurethane should not be applied over red mahogany stains. Instead use Minwax® Fast Drying Polyurethane or Minwax® Water-Based Oil-Modified Polyurethane over any red mahogany stain. Minwax® One Coat Polyurethane is not recommended for use on floors because it would require more frequent recoating in high traffic areas. Instead, we recommend any Minwax® Super Fast Drying Polyurethane for Floors or Minwax® Ultimate Floor Finish for maximum durability.

Frequently Asked Questions

What is Minwax® One Coat Polyurethane?

It is a crystal clear, non-ambering protective finish that provides the same level of protection in one coat as three coats of a traditional polyurethane. It can be used over bare wood and both oil-based and water-based stains.

What are the advantages of using Minwax® One Coat Polyurethane?

One Coat Polyurethane lets you complete projects three times faster. It provides the same level of durability in one coat that is comparable to three coats of a conventional polyurethane, it dries in two hours, and cleans up with soap and water. Because it’s crystal clear, it is ideal over light-colored woods and water based stains.

Can Minwax® One Coat Polyurethane be used over Minwax® Wood Finish™ stains?

Yes, provided the Wood Finish™ stain has dried completely, which generally takes 24 hours. The only exception is over Wood Finish™ Red Mahogany Stain. The two products are not compativle so you should use Minwax® Fast Drying Polyurethane or Minwax® Water Based Oil-Modified Polyurethane.

Why does Minwax® One Coat Polyurethane appear milky in the can?

The milk-white appearance is caused by the scattering and reflection of light striking the liquid and particles suspended in it. The slight haziness disappears on the wood leaving a clear finish.
