Clear Seal™ 100% Urethane Single-Part is a single-part urethane coating that creates a protective film for painted and unpainted surfaces. This product creates a hard glossy film that is more UV resistant, stain resistant, and hot tire resistant than that of Clear-Seal™ acrylic urethane. It also protects against physical abrasion and spills. For a faster cure time use the Clear-Seal™ 100% Urethane Two-Part Kit, which also increases physical and chemical resistance.


  • Impact and wear resistant
  • Single component – no mixing required
  • Gloss finish will not yellow or cloud
  • Easy application – no mixing required
  • Resistant to acids, bases, gasoline, alcohol & oil
  • May be applied at 50°F-90°F

How to Use

1) Prepare Surface

To apply, surfaces must be clean, dry, and structurally sound. Surface moisture content must be less than 15% as measured with an electronic moisture meter. Do not apply if relative humidity is greater than 80%.

2) Stir Product

Stir well for 5-10 minutes.

3) Apply Clear Seal™ 100%

Pour into paint tray. Using 3/4 inch nap roller, apply even coat to horizontal or vertical surface. For best results, apply solution in cross-hatch pattern. WARNING: Make sure surface has been completely dry for at least 48 hours prior to application. Before applying additional coats, make sure that the surface is dry to the touch.
