Description
Professional grade polyurethane sealant engineered to withstand adverse weather conditions and cure to a flexible, weather-resistant seal.
The Geocel 3300 Professional Grade Polyurethane Sealant is a single-component, high-performance formula that delivers reliable adhesion across a wide range of common building substrates — including stone, masonry, ceramics, wood, steel, aluminum, asphalt, BUR, concrete, fiberglass, vinyl, and more. Primerless adhesion on most substrates means faster application and fewer steps on the job site.
The moisture-cure formula stays flexible with minimal shrinkage and a non-sag consistency that holds in place during application. Paintable and non-corrosive with no TDI (toluene diisocyanate) — a safer, cleaner choice for professional contractors.
