Why Geocel Gutter Sealer Should Always Be in Your Truck

Seal It Once. Don’t Go Back.

Leaks at seams, joints, and outlets are one of the top reasons for callbacks. If you’re using cheap sealant, you’re gambling with your work. Geocel Gutter Sealer 2320® is a jobsite-proven tri-polymer formula built to stop air and water in their tracks—and stay flexible over time.

It grabs onto metal, masonry, vinyl, and even damp or oily surfaces. It’s paintable, UV-resistant, and compatible with asphalt shingles, making it the right sealant for real-world installs.

Built for the Jobsite, Not the Shelf

• Strong adhesion even on damp or oily surfaces
  

• UV stable — won’t crack or chalk in the sun

• Paintable — blends with any trim or fascia finish

• Semi-self-leveling — fills gaps without sagging

• Cleans up easy — no fight at the end of the day

• Shingle safe — won’t damage roofing materials

Whether you’re sealing gutter seams, downspout outlets, or miters, this is the stuff that holds.

Specs That Matter

Where Pros Use It

• Gutter seams and end caps

• Miter joints (box, strip, and extreme)

This isn’t just for gutters—it’s for any part of the exterior that needs sealed tight and sealed fast.

FAQs

Can I use it on wet surfaces?
Yes. It bonds to damp or oily surfaces without issue.

Is this compatible with asphalt shingles?
Yes, it’s specifically formulated to be shingle-safe.

Do I need special tools to apply it?
Nope. Standard caulking gun works just fine.

What’s the difference between this and regular silicone?
Geocel 2320 is a tri-polymer that bonds better, holds up to UV, and stays flexible. Silicone doesn’t do all that on aluminum or under paint.
