It comes ready to use so mixability is easy to get started. It's a great price. The Flex Seal is very durable, looks great and clean up is easy so removal is easy. The product seems sturdy. Review: After using every other brand out there, on a multitude of projects.....Flex Seal is hands down the winner. Yeah, I know the cheesy ads on TV bothered me too. I always thought it wouldn't be worth my money too. I've gotta say it is legit great. This gray is your average gray, so it blends well. I am a believer, try it. You do need multiple coats, and it needs 3 days to actually cure pretty hard. The longer the cure, the tougher the coating will be out in the elements. Once it's cured, you have a UV tolerate item. It does fade slightly over time, but so does everything else. This is my opinion on this spray style, nothing else. ## Features - The Colorful Way to Coat, Seal and Stop Leaks Fast! - Seeps into cracks and holes, Seals out water, lasts for years - Dries to a watertight, flexible rubberized coating - Ideal for arts & crafts, projects & hobbies, and sealing outdoor decorate items - Transform and protect virtually everything - Perfect for Gutters, Wood, RV, Campers, Roof Repairs, Skylights, Windows, and more ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00W5Y2X2W | | Best Sellers Rank | #217,726 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #42 in Adhesive Sprays | | Brand Name | Flex Seal | | Color | Gray | | Compatible Material | Rubber | | Customer Reviews | 4.5 4.5 out of 5 stars (1,071) | | Global Trade Identification Number | 00810129871937 | | Item Dimensions | 13.2 x 6.6 x 22.9 centimeters | | Item Form | Spray | | Item Weight | 28 Ounces | | Manufacturer | Swift Response, LLC | | Material Type | Rubber | | Model | FSGRYR20 | | Number of Items | 2 | | Part Number | FSSLVD20 | | Style Name | Compact | | Surface Recommendation | Roof | | UPC | 810129871937 | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Flex Seal - **Item dimensions L x W x H:** 13.2 x 6.6 x 22.9 centimeters - **Item weight:** 28 Ounces - **Material:** Rubber - **Style:** Compact ## Images ![Flex Seal, 14 oz, 2-Pack, Gray, Stop Leaks Instantly, Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More - Image 1](https://m.media-amazon.com/images/I/81+94YgwaaL.jpg) ## Questions & Answers **Q: Will it stick to outdoor wood and is it paintable?** A: I believe it would stick to wood outdoors. I can't verify that it can be painted as I've never tried to paint it. **Q: Would this work on an exterior chimney crown?** A: It worked on a brick in my kitchen so yes it would however you might want to try the Paste version as opposed to the spray. The stuff is wonderful. No house should be without it. **Q: Will this product break down the composition of styrofoam?** A: Hey there. We don't recommend using Flex Seal Spray on a styrofoam surface as the spray will cause the styrofoam to melt when it comes in contact with the spray. **Q: Does come with texture? I want to use it the floor of a motorcycle trailer** A: It has no texture. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***D on 20 February 2026* Flex Seal is great quality.
