Product Overview

Gorilla's Window and Door Sealant is a 100 percent silicone, waterproof sealant designed for both interior and exterior use around windows and doors. It forms a flexible, durable seal that resists mold, mildew, shrinking, yellowing, or cracking over time. Within about 30 minutes of application (for typical bead size and optimal conditions), the sealant becomes water-ready, though full curing takes longer. It adheres well to surfaces such as glass, metal, wood, and vinyl, it's temperature-resistant (spanning well below freezing up to hot summer heat) and meets ASTM C-920 Movement Class 35 for flexibility and joint movement. While it provides excellent durability and reliable weather protection, it is not paintable, and surfaces should be clean, dry (not wet or frozen), and free of oil or contaminants for best performance.
