Thick glue with a good seal. Top notch. ### ⭐⭐⭐⭐⭐ Review *by R***. on 10 September 2025* Great price for how much you get. Very sticky. Easy to use. I use on my hvac registers after cleaning them up. Keeps attic air out. Seems like quality product. Very strong. Does its job by making an airtight seal. ### ⭐⭐⭐⭐⭐ Review *by C***0 on 1 September 2022* There's no better tape period, this is the real deal. Quality product, pricy, but worth every penny. I had multiple air bleed connecting seams, did my entire basement ductwork with 100 feet and some left over to do a few more seams. Get some little scissors to cut it with, makes life easier. The utility blade crumples the corners a bit, which makes it trickier to get the backing off. Hope this helps! ## Frequently Bought Together - Hardcast 304099 Foil-Grip 1402 Mastic Duct Sealant 2" x 100' - Nashua 365 Polyethylene Coated Cloth Professional Grade Duct Tape, 55m Length x 72mm Width, Metallic - Rolled Mastic Duct Sealants Foils 3'' X100 --- ## 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.kr/products/390248018-foil-grip-1402-mastic-duct-sealant-2-x-100](https://www.desertcart.kr/products/390248018-foil-grip-1402-mastic-duct-sealant-2-x-100) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-30*
