Geocel 2320 Gutter Sealant White – 3 Tubes Pack | High-Performance Sealant

Geocel 2320 Gutter and Narrow Seam Sealant

Geocel 2320 is a single‑component elastomeric sealant engineered to block air and moisture through small joints and seams. Its semi‑self‑leveling, tripolymer formula helps create a consistent bead that adapts to minor movement along gutters and roofline joints, reducing draft and potential leaks without taking on a heavy, stiff feel.

Designed for exterior use, the product offers strong adhesion to a broad range of substrates, even when surfaces are damp or oily. Its UV resistance helps maintain flexibility and color over time, while the sealant remains paintable for easy aesthetic touch‑ups. Cleanup is straightforward, and the material can be applied directly from the tube without mixing.

Where it works best

Geocel 2320 is suitable for asphalt shingles, brick (masonry), concrete, glass, vinyl, wood, sheet metal, and other common building substrates. It’s specifically intended for gutters and narrow seams where small gaps need a durable, flexible seal and where movement from weather or structural shifts is possible.

Practical usage tips
