WAXIE Diamond Guard S Sealer A non-yellowing urethane based sealer, which functions as a sealer/barrier/bonding primer under WAXIE urethane floor finishing systems. It also works to enhance gloss and depth-of-image (DOI) of the final finish. This sealer equalizes and stabilizes high surface tension on the floor and acts as a bonding primer for the WAXIE Diamond Guard RF Urethane Floor Finish with the difficult-to-adhere surfaces that are typical of flexible laminates on the market today. When used on VCT, WAXIE Diamond Guard S Sealer acts as a barrier primer, preventing the WAXIE Diamond Guard RF Urethane Floor Finish from penetrating the porous surface of the VCT tile. Additionally it acts as barrier for plasticizer migration that keeps the VCT from migrating through the WAXIE Diamond Guard RF Urethane Floor Finish, which will cause gloss degradation. WAXIE Diamond Guard S Sealer can reduce strip-out times by 30-50% and is a dramatic time saver (aid in strippability) for future removal of WAXIE Diamond Guard RF Urethane Floor Finish. One gallon can cover 1200-1500 square feet.
