Apparently it won’t provide solace for those exposed to radiation. Or anyone in current times. New product for me? Lmk. ### ⭐⭐⭐⭐ Easy to apply *by S***Y on June 14, 2025* It works, easy to apply ### ⭐⭐⭐⭐⭐ Excellent product *by T***Y on April 9, 2023* I was skeptical at first, but this acoustic caulk did everything and more. I stay in a poorly soundproofed apartment. This product does just as great if not better than expensive acoustic treatments by lowering noise transmission traveling through the vibrations between walls. I kid not, the bass coming from my neighbors walls went down to a level that I couldn’t imagine. The noise from the loud outdoor AC lowered a bit once I applied some around the windows. I’m very happy with this purchase. It even helped lower the amount of impact noise from footsteps I was also hearing along shared walls. Well worth the spend. ## Frequently Bought Together - BOSS 826 Acoustical Sound Sealant - 29 oz Tube White - Soundsulate 1 lb Mass Loaded Vinyl Soundproofing 4' x 25' (100 sf), Made in USA, Click for Options - UberQuiet MLV Cap Nails, 1-inch, for Installation of Mass-Loaded Vinyl Noise Barriers, Small (250 pcs) --- ## 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.vu/products/442666517-boss-826-acoustical-sound-sealant-29-oz-tube-white](https://www.desertcart.vu/products/442666517-boss-826-acoustical-sound-sealant-29-oz-tube-white) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
