TL;DR
Gutter sealant is a flexible, self-leveling or gunnable compound, usually tripolymer or polyurethane, used to waterproof gutter seams, end caps, outlets, and mitres where metal parts overlap. Unlike silicone bath caulk it bonds to aluminum under permanent water immersion and flexes with thermal movement across seasons.
What it means
Gutter sealant is a flexible, self-leveling or gunnable compound, usually tripolymer or polyurethane, used to waterproof gutter seams, end caps, outlets, and mitres where metal parts overlap. Unlike silicone bath caulk it bonds to aluminum under permanent water immersion and flexes with thermal movement across seasons. Surfaces must be cleaned of oxidation and old residue for adhesion, and a properly tooled joint lasts 5 to 20 years, making reseals a routine maintenance line on older sectional systems.
