Skylight Sealer
High-Performance Transparent Coating & Sealer for Skylights and Panels
Skylight Sealer is a two-part fluoropolymer urethane coating that delivers a tough, clear, and UV-stable finish for skylights, roof panels, and architectural surfaces. Engineered to extend surface life without yellowing or haze, this gloss-finish sealer provides excellent chemical, abrasion, and weather resistance while flexing with surface movement.
Skylight Sealer is fast-setting, easy to apply, and designed for use over previously coated or painted substrates. With strong adhesion and a low VOC formula, it's the go-to solution for preserving skylight clarity and restoring visibility—without sacrificing durability.
