I squeezed out the thick silver grey goop ... - This stuff is great! I squeezed out the thick silver grey goop on to the seems, was a little pessimistic, and finished the job in minutes. The next day came back and I had a wonderful solid seal, now very optimistic. Compared to similar products sold by big box stores (i.e. Lowes, Home Depot, etc...) this stuff out performs what they offer hands down. I only have two suggestions to the manufacturer; 1) Add a screw on nozzle, similar to a tube of caulk, where we can cut the tip to the desired thickness of the material, as well as being able to control the flow better. It's difficult to get behind a gutter that butts up to a house without this type of feature. I had to squeeze out the stuff onto my finger (latex gloves, check) and smear the stuff onto the seam. Although I may have had to still do this with a nozzle, at least with the nozzle I could have controlled placing the material onto the seam first. 2) How about making this stuff in white. Not sure about the majority of people, but where I live, the majority of gutters are white. This stuff is silver grey and you can see the stripes going around the length of my gutters. I'll have to spray paint them white when the weather permits, but it certainly would be a nice plus to your product if this was yet another task I didn't need to do. If you do make this stuff in white, please get a hold of your distributors or resellers and ask them to make it available to us. Great stuff though. Review: I cleaned the seams with mineral spirits as best I could and then wearing gloves applied the Geocel ... - This stuff works. I have gutters that are 20 years old that were leaking. My gutters go around the entire house and connect in each corner. At the corners of the house the gutters are overlapped, machine screwed together and sealed with the original sealant from 20 years ago. I tried some DAP Gutter and Flashing Sealant. The DAP product stuck to me and would not stick to the aluminum gutters. I would imagine the DAP product would work on new, perfectly clean aluminum, but lets get real that isn't the real world. My gutters are 23 feet above the ground so working with a marginal product is not acceptable. I cleaned the seams with mineral spirits as best I could and then wearing gloves applied the Geocel with my fingers and a plastic putty knife to feather the Geocel out from the seams. This stuff is somewhat thick and works better when warm, but I was able to get it to work on a 65 degree day. Bottomline: Geocel will stick to old aluminum gutters that are cleaned when other products will not and will seal the gutter seams to stop leaks. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LNX0X0 | | Brand | Geocel | | Brand Name | Geocel | | Compatible Material | Aluminum, Galvanized Steel, Copper, Pvc, Vinyl, Wood | | Customer Reviews | 4.3 out of 5 stars 409 Reviews | | Included Components | Geocel Corp. 29402 Instant Gutter Seal | | Item Dimensions | 2.5 x 1 x 8 inches | | Item Form | Paste | | Item Type Name | Geocel Corp. 29402 Instant Gutter Seal | | Item dimensions L x W x H | 2.5 x 1 x 8 inches | | Manufacturer | Geocel Corp. | | Material | Silicone | | Material Type | Silicone | | Model | 29002 | | Part Number | 29402 | | Style | Compact | | Style Name | Compact | | Surface Recommendation | Gutter | | UPC | 079239290025 | | Unit Count | 1.0 Count | | Water Resistance Level | Water Resistant | ## Images ![Geocel Corp. 29402 Instant Gutter Seal - Image 1](https://m.media-amazon.com/images/I/61DeE-f5pIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This stuff is great!

It is easy to use and once hardened, makes a very good seal. I used it to join the overlap at outside corners of a leaf shedding gutter screening product. Since it didn't harden immediately or within a few hours, I had to also screw the sections of screen together to hold it in place. This would not be a problem with sealing the seams of aluminum gutters themselves, as they must be screwed together anyway initially regardless of which type of seal was also used (to prevent leaks). It can be used in the rain or cold temperatures, which is very helpful and important. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/4426571-geocel-corp-29402-instant-gutter-seal](https://www.desertcart.co.uk/products/4426571-geocel-corp-29402-instant-gutter-seal) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-12*
