This is recommended to keep embers from wildfire from getting into your crawlspace and setting your house on fire. ### ⭐⭐⭐ Hard to Apply *by on Reviewed in the United States 15 December 2022* This stuff is really thick and not easy to spread. We went through a ton of gloves finishing our project. We needed it for our firewall to pass inspection and it did do the job. ## Frequently Bought Together - HIlti 2101531 FS-ONE MAX 10.1oz Tube (1 Tube) firestop fire Protection Systems - HIlti 2116245 Firestop Cable Disc CFS-D 1" firestop fire Protection Systems - 3M Fire Barrier Moldable Putty Stix MP+, Red Color, One-Part, Re-Enterable, Intumescent, 1.45 in x 6 in --- ## 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.jp/products/741624121-hilti-2101531-fs-one-max-10oz-tube-1-tube-firestop](https://www.desertcart.jp/products/741624121-hilti-2101531-fs-one-max-10oz-tube-1-tube-firestop) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-29*
