Why Geocel 2320 Outperforms Silicone and Latex
Standard silicone caulk requires a completely dry, clean surface and a minimum 24-hour rain-free window before application. Latex caulk shrinks and cracks in freeze-thaw cycles. Geocel 2320 Tripolymer eliminates both limitations:

Frequently Asked Questions
Can Geocel 2320 be applied to wet gutters?
Yes. Geocel 2320 is specifically formulated to bond to wet or dry surfaces. Unlike silicone caulk that requires a completely dry surface, 2320 can be applied during rainfall for emergency leak repair.
What surfaces does Geocel 2320 bond to?
Geocel 2320 bonds without primers to aluminum, galvanized steel, copper, vinyl, wood, concrete, and most painted surfaces — compatible with all standard gutter materials.
How long does Geocel 2320 take to cure?
Tack-free in approximately 1 hour at 70°F/50% humidity. Full cure takes 24 to 48 hours. Cold or humid conditions may extend cure time slightly.
Is Geocel 2320 paintable?
Yes. After full cure (24–48 hours), Geocel 2320 can be top-coated with latex or oil-based paint. The aluminum gray color blends naturally with most gutter systems.
What is the difference between single, 3 pack, and box of 24?
The single is one 10.3 oz cartridge ideal for spot repairs. The 3 pack suits medium projects. The box of 24 is the contractor case offering the lowest per-unit cost for large jobs or ongoing maintenance contracts.
Does GutterAll offer contractor pricing on bulk orders?
Yes. Contact us at sales@gutterall.com or call (503) 496-7017 Monday–Friday 7am–4pm PT to discuss volume pricing on the Box of 24.

Mike T. September 12, 2025 5/5
Applied this during a rainstorm to fix a leaking gutter seam. It bonded immediately and the leak stopped. Three months later still holding. Incredible product.
Rachel S. August 3, 2025 5/5
Ordered the box of 24 for a full gutter re-sealing job. Much better than the silicone caulk we used previously. No cracking after the first winter.
Dave K. July 18, 2025 5/5
Professional gutter contractor here. This is the only sealant I trust for wet-apply situations. GutterAll had the best price on the 24-count box.
