Sikalastic® Clearglaze is a clear, high-solids, polycarbonate aliphatic polyurethane-based coating that protects skylights and glazings against air, rain, hail, snow, and dirt. Its transparent finish retains the appearance of the underlying substrate and still allows light to pass through. This restoration is part of a Sikalastic RoofPro System. Combining toughness with excellent adhesion, the Clearglaze provides a great alternative to expensive replacement of leaking/deteriorated skylights while enhancing the shatter resistance of the original glass. Local reinforcement can repair existing cracks with limited blurring.
