I recommend using latex gloves because if you get this on your finger it will be all over your body before you know it.. lol ### ⭐⭐⭐⭐ Initial Feedback *by R***R on September 7, 2023* It is too early to comment on how well this product fixes the leaks on my backyard pond as It is only 2 days post installation. I’m commenting now to help others as they consider this product who may be concerned about multiple reviews stating how messy this product is. This was a concern as I considered the pros and cons of the purchase. This product is no more or less messy than any type of adhesive caulking I have ever installed. Of course if you are not careful it can be a problem. Simply take your time to get the nozzle cut to the volume you want to apply and then run your bead accordingly. I found the info online adequate to understand how to prep and apply the product. If the product performs as specified I wil change the review to 5 stars. ## Frequently Bought Together - Gold Label Underwater Sealant, 290 ml, Black - TotalPond Waterfall Foam Sealant - GREAT STUFF 99112849 Smart Dispenser Pond & Stone, 12 oz, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/23334333-gold-label-underwater-sealant-290-ml-black](https://www.desertcart.kr/products/23334333-gold-label-underwater-sealant-290-ml-black) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-07-14*
