Review: Perfect product but follow ALL directions - This product works well. I got it for a hole that was drilled during the cable installation. I followed the directions and it was simple to use. Be very careful to use gloves and not get on any clothes. Although I read the warning, I ignored the advice and have a small spot on my coat sleeve because of my “I’m careful and won’t get any on me” careless mindset. Review: 1 can per decoy. - My decoy broke. This fixed it enough to use. This and duct tape, or should I call it duck tape since it was a duck decoy. It floats now and that's what matters. ## Features - FILLS LARGE HOLES, GAPS & CRACKS: Ideal for insulating and preventing drafts - USE INSIDE OR OUTSIDE: Can be used anywhere around the home - SANDABLE, PAINTABLE & STAINABLE: Can be sanded, painted or stained after curing - ADHERES TO: Painted and unpainted wood, concrete, cinder block, aluminum & fiberglass - SOLVENT CLEAN UP: Requires the use of a solvent for cleanup ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000UOCEUA | | Best Sellers Rank | #34,969 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #73 in Urethane Adhesives | | Brand Name | Red Devil | | Color | Off-White | | Compatible Material | Alloy Steel | | Customer Reviews | 4.2 4.2 out of 5 stars (2,942) | | Global Trade Identification Number | 00075339009123 | | Included Components | 1 | | Item Dimensions | 2.5 x 2.5 x 12 inches | | Item Form | Foam | | Item Type Name | Large Gaps & Cracks Polyurethane Foam Sealant | | Item Weight | 1.6 Pounds | | Manufacturer | Red Devil Inc. | | Material Type | Polyurethane | | Model | 0912 | | Number of Items | 1 | | Part Number | 0912 | | Style Name | Pack of 1 | | Supported Standards | UL | | Surface Recommendation | Window | | UPC | 330051248152 075339009123 | | Unit Count | 20.0 Ounce | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Red Devil - **Item Weight:** 1.6 Pounds - **Item dimensions L x W x H:** 2.5 x 2.5 x 12 inches - **Material:** Polyurethane - **Style:** Pack of 1 ## Images ![Red Devil 0912 Spray Foam, Fill Large Gaps, Cracks Expanding Insulation Polyurethane Sealant, 20 oz., Off-White, Pack of 1 - Image 1](https://m.media-amazon.com/images/I/61l5HBXB24L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: can it be used to fill cracks in old wood floors?** A: It expands quite a bit I would recommend the small gap stuff it doesn't expand **Q: If I have some erosion under my walkway will this be an acceptable fill?** A: Likely not. The foam will certainly fill the gaps, but even once it sets, it's still pretty soft. It wouldn't provide any support. It might prevent further erosion, though **Q: Is this product closed cell foam?** A: Hello, this product is considered open cell. However, our open cell count is far less than any competitive product you will find on the market. So once it's cured, it forms an air and watertight seal. Thanks! **Q: is this fire proof?** A: Hi, no it is not, if you need our fire proof foam, I have posted the link for you below.

I got it for a hole that was drilled during the cable installation. I followed the directions and it was simple to use. Be very careful to use gloves and not get on any clothes. Although I read the warning, I ignored the advice and have a small spot on my coat sleeve because of my “I’m careful and won’t get any on me” careless mindset. ### ⭐⭐⭐⭐⭐ 1 can per decoy. *by C***M on May 13, 2024* My decoy broke. This fixed it enough to use. This and duct tape, or should I call it duck tape since it was a duck decoy. It floats now and that's what matters. ### ⭐⭐⭐⭐ Good But Messy *by A***S on October 29, 2022* The foam does form a solid grip and water tight seal. I was looking for this installation ability. Unfortunately the bottle exploded on my most loved sweater and shoes at the application end. When I use super glue or caulk gel I do not have to wear a full smock and work boots. I wish the instructions had warned me more of the mess this stuff makes! After it dried I was able to trim and sand the splatters off, and it had a smooth window installation. Worth the price but needs more mess warnings! ## Frequently Bought Together - Red Devil 0912 Foam & Fill Large Gaps & Cracks Expanding Polyurethane Sealant, 20 oz., Off-White, Pack of 1 - Alabrocon Steel Wool Fill Fabric DIY Kit, Coarse Wire Wool Hardware Cloth, Gap Blocker, Keep Mice Away from Holes/Siding/Pipeline/Vents in Garden, House, 2 Pack × 10FT - Red Devil 0913 Foam & Fill Small Gaps & s Expanding Polyurethane Sealant, 12 oz, Off-White, Pack of 1 --- ## 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.dk/products/7714380-red-devil-0912-spray-foam-fill-large-gaps-cracks-expanding](https://www.desertcart.dk/products/7714380-red-devil-0912-spray-foam-fill-large-gaps-cracks-expanding) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-13*
