Clear-Seal 100% Urethane High Gloss Super Premium Sealer

Rainguard Clear-Seal™ 100% Urethane is an exceptionally tough, durable and breathable low gloss sealer.  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 blended sealer.  It provides a nice looking high gloss finish for concrete, stone, masonry, unglazed tile and wood surfaces.  It is a water based, low VOC, single-component, self cross-linking clear urethane water based sealer.

Clear-seal is available in both a High Gloss and Low Gloss formula in 1 gallon and 5 gallon containers. For optimal results, add Urethane Quick Cure Performance Additive (select this option under the Performance Additive dropdown).

Clear-Seal is designed to increase chemical resistance, impact resistance, chip resistance, added UV protection and better absorption of the Clear-Seal.  Urethane Quick Cure Performance Additive mixes easily.  Add 2 oz of Urethane Quick Cure per gallon of Clear-Seal™ 100% Urethane. Mix 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.
