    Clear Seal™ 100%  Urethane Two-Part Kit is a two-part urethane coating that creates a protective film for painted and unpainted surfaces. It comes with IsoFree™, Quick Cure additive to create 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 and has a faster cure time than Clear-Seal™ 100% Urethane Single-Part.

    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) Mix in Additive

    Add 2 oz of Urethane Quick Cure per gallon of Clear-Seal™ 100% Urethane. Mix well for 5-10 minutes. Adding Urethane Quick Cure gives the solution a 72-hour pot life. Extend pot life by adding more Urethane Quick Cure if needed.

    3) Apply Clear Seal™ 100%

    Stir solution for 1-2 minutes and 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.
