Geocel 2320 Gutter and Narrow Seam Sealant – Clear, 10.3 fl oz, 3 Pack

Geocel 2320 is a clear tripolymer sealant made for gutter joints and other narrow seams where air and water find a way in. This pack holds three 10.3 fl oz cartridges. It is a single-component, elastomeric product, so there is nothing to mix. Once set, it stays flexible and moves with the joint as metal and wood expand and contract.

Why gutter installers like it

Gutters are rarely perfectly clean or dry when they need sealing. Geocel 2320 bonds to damp and even oily surfaces, which most caulks will not. Its semi-self-levelling consistency lets it flow into a seam and lie flat, so you get an even fill without a lot of tooling. It resists UV, so it keeps its colour and flexibility in full sun.

Substrates

• Asphalt shingles and roofline joints
• Brick, masonry and mortar joints
• Concrete
• Glass and vinyl
• Wood trim
• Sheet metal, gutters and flashing

Beyond gutters, it is useful for gaps around vents and flashing, seams in metal assemblies and narrow masonry joints. Because it is paintable, you can match it to trim or siding when the bead shows. Geocel has made sealants since 1974.

Application tip: clean off dust, oil and loose material, cut the nozzle to the bead size you need and apply with steady pressure. Smooth the bead if you want a crisp line. It cleans up easily while still wet. Follow the label for drying time before painting.
