Tested to withstand temperatures from -37°C to +40°C, it offers long-lasting durability and superior adhesion on a variety of materials, making it ideal for professional-grade waterproofing and sealing projects. ## Description FLEX SEAL LIQUID is a patent pending, proprietary formulation that starts out as a thick liquid and dries to a super strong, flexible, watertight rubberized coating. FLEX SEAL LIQUID can be brushed, rolled, dipped or poured to create a high performance protective rubber barrier that blocks out air, water and moisture on a variety of surfaces and objects. Once cured, FLEX SEAL LIQUID forms a durable, breathable, weatherproof, non slip barrier that's resistant to rain, snow, sun, wind, hail, air, moisture, UV degradation, extreme temperatures and natural weathering. HOW TO BRUSH, ROLL, DIP, POUR Protective clothing is recommended. Stir can well, do not shake. Make sure the surface is clean, dry and free of grease, oil and dirt. For better adhesion, scuff surface with sand paper or steel wool. Coverage will vary depending on amounts of coats used. 1 Large 16oz - approx. 20Sq. Ft., 1 Jumbo 32oz - approx. 40Sq. Ft., 1 Gallon can - approx. 150Sq. Ft., Brush or roll FLEX SEAL LIQUID using an even sweeping motion. Apply several even coats until the surface has been completely covered and ALL cracks and holes have been filled. Allow FLEX SEAL LIQUID to dry 24 to 48 hours and apply additional coats as needed. Always brush or roll over a larger area than just where the leak occurred. Dip object directly into the FLEX SEAL LIQUID make a slight swirling motion. Once the surface has been coated, remove and let any excess drip back into the can. Hang or clip the object in the same vertical position as it came out of the can and let dry. Pour FLEX SEAL LIQUID directly on the surface allowing gravity to take FLEX SEAL LIQUID into cracks, holes and hard to reach areas. Continue to pour until the surface has been covered and all cracks and holes have been completely filled. Review: The liquid in a can is great for waterproofing outdoors. I have used it on the skylight curbs and gutters on my sunroom. Has not shown any signs of wear or cracking during the past 3 years. Has withstood +40 celsius to minus 37 celsius. The liquid version of this product is better than the spray version. Review: Very good, clean/dry concrete surface, it adhered and dried very well. ## Features - Causes serious eye irritation. - Causes skin irritation. - May cause an allergic skin reaction. - May cause damage to organs (Blood, Cardiovascular system) through prolonged or repeated exposure. - made in china ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01GFYA482 | | Batteries Required? | No | | Batteries included? | No | | Colour | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (660) | | Date First Available | 18 Aug. 2016 | | Included components | Gallon Flex Seal Liquid | | Item Package Quantity | 1 | | Item Weight | 5.13 kg | | Item model number | LFSBLKR01 | | Manufacturer | Swift Response, LLC | | Material | Rubber | | Part number | LFSBLKD01 | | Product Dimensions | 19.69 x 16.51 x 16.51 cm; 5.13 kg | | Size | 1-Gal | | Specification met | Not Applicable | | Style | Protective | ## Product Details - **Brand:** Flex Seal Liquid - **Item dimensions L x W x H:** 19.7 x 16.5 x 16.5 centimetres - **Item weight:** 5.13 kg - **Material:** Rubber - **Style:** Protective ## Images ![Flex Seal Liquid Rubber in a Can, 1-gal, Black, LFSBLKR01 - Image 1](https://m.media-amazon.com/images/I/51N-aPdMziL.jpg) ![Flex Seal Liquid Rubber in a Can, 1-gal, Black, LFSBLKR01 - Image 2](https://m.media-amazon.com/images/I/51OjdrX9UcL.jpg) ![Flex Seal Liquid Rubber in a Can, 1-gal, Black, LFSBLKR01 - Image 3](https://m.media-amazon.com/images/I/51P5gZJNBEL.jpg) ![Flex Seal Liquid Rubber in a Can, 1-gal, Black, LFSBLKR01 - Image 4](https://m.media-amazon.com/images/I/51QEDuNSMmL.jpg) ![Flex Seal Liquid Rubber in a Can, 1-gal, Black, LFSBLKR01 - Image 5](https://m.media-amazon.com/images/I/51eBfQyz9gL.jpg) ## Questions & Answers **Q: Can this be used in 1" space between concrete slabs on a driveway?** A: Yes many people have had great success using Flex Seal Liquid to fill in cracks and holes in their driveway.You can pour it right in to fill the spaces. **Q: Can this product be used to seal cracks in an asphalt driveway?** A: Yes Flex Seal Liquid can be used to fill in cracks in asphalt. **Q: What temperataures are the best for application of Flex Seal?** A: Flex Seal liquid temperature range is from -0 degrees - 250 degrees Fahrenheit. **Q: How much area can a 32oz can cover?? please and thanks** A: Thank you for reaching out!
