Clear-Seal 100% Urethane Low Gloss Super Premium Sealer

Rainguard Clear-Seal™ 100% Urethane is an exceptionally tough, durable and breathable low gloss sealer.  This product creates a hard low gloss 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 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 Low gloss and High Gloss formula in 1 gallon and 5 gallon containers. For optimal results, add Urethane Quick Cure Performance Additive. It 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 (select this option under the Performance Additive dropdown).  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.
