Offering superior flexibility with 950% elongation and professional coverage up to 30 sq ft per gallon, it forms a durable, eco-friendly waterproof membrane ideal for roofs, foundations, gutters, and more. Trusted by contractors and DIYers alike, it resists cracking, UV damage, and adheres to most building materials for long-lasting protection indoors and outdoors. ## Description Liquid Rubber Waterproof Sealant is a premium waterproofing solution that creates a seamless, flexible membrane for ultimate protection against leaks and water damage. This professional-grade roof coating combines quality bitumen polymers with ease of use to deliver long-lasting results for any DIY or professional project. Transform your flat roof, metal roof, or low slope roof with a durable protective barrier that prevents leaks and extends the life of your structure. Our industrial-grade formula also excels at foundation waterproofing, gutter repair, concrete sealer applications, planter boxes, and more. The high-performance elastomeric membrane creates a watertight seal that stands up to harsh weather conditions. Technical Results with Simple Application: Unlike complicated roof repair systems, Liquid Rubber applies easily with standard tools - simply use a brush, roller, or sprayer. The formula provides excellent coverage and adhesion to most building materials. For flat/standing water surfaces, apply 3-4 heavy coats to achieve a 60-80 mil membrane (1 gallon covers approximately 15 sq ft). For vertical surfaces like foundations, apply 2-3 heavy coats (1 gallon covers approximately 30 sq ft). Advanced Formula for Challenging Projects: Our water-based formula contains no solvents, VOCs, or harmful odors, making it safer than traditional roof tar or solvent-based sealants. Integrated Waterproofing System: For maximum protection and longevity, use Liquid Rubber Seam Tape or Geo-Textile to reinforce seams, joints, and areas prone to movement. This approach creates a bulletproof waterproofing system that prevents leaks before they start. With millions of gallons sold, Liquid Rubber is used by contractors and professional applicators who demand superior results. Don't settle for sealants that crack and peel - choose the premium waterproof sealant that delivers lasting protection and reliability for your roof, foundation, or basement waterproofing project. Review: Quite impressed - Excellent done the job perfectly Review: Wow, this stuff seals and lasts - I had a fountain that leaked through some cracks. I tried the brand or sealant advertised on TV, you know, the bias with sealed screen door in the bottom. Seven coats, it never really sealed and lasted about 6 months. 3 coats of this stuff and a year and a half later, it’s sealed up tight. I really like this stuff. I wonder how it works as underbody protection on a car….. ## Features - INDUSTRIAL STRENGTH BITUMEN FORMULA - Create a seamless waterproof membrane on flat roofs, metal roofs, low slope roofs, foundations, gutters, concrete surfaces, planter boxes, and more.

We are sealing our new concrete pond with this product = will not have fish in** A: New concrete needs to cure as per the installation instructions. Applying any of the Liquid Rubber products or most waterproofing products prior to a full cure may compromise the curing process of the concrete. **Q: I have a black plastic pond i got from home depot. will it adhere to that material?** A: Yes, put a few coats on. Let each coat dry well (24)hrs . You can spray on inside of pond. I used a undercoating product used for undercoating cars for the outside of pond. I put 3 coats on. I let each coat dry for 2 days before applying the next coat. All worked great my pond is like new and no leaks and all of my goldfish are fat and happy! Good luck! Take your time and cover every spot even sides. Make sure the pond is very clean before u start applications. I used a ruff kitchen pot scrubber to scrub clean. **Q: Does this project leave much of an odor after it has set?** A: Haven't smelled any odor. When putting it on there is a usual rubber smell like a basketball, but it doesn't seem to last very long. And it smells just like putting rubber on, which wasn't bad. It works for me. **Q: what color is it when it dries?** A: The product is brown when it is wet and black when it dries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quite impressed *by A***R on 21 August 2026* Excellent done the job perfectly ### ⭐⭐⭐⭐⭐ Wow, this stuff seals and lasts *by G***N on 21 July 2026* I had a fountain that leaked through some cracks.
