It covers up to 30 sq ft vertically and 15 sq ft on flat surfaces per gallon, curing in 24-48 hours without harmful VOCs or odors. Ideal for professional-grade DIY repairs, it pairs with seam tape or geo-textile for enhanced joint protection. ## Description Liquid Rubber Waterproof Sealant is coating that is easily brushed on and cures into a waterproof membrane. It can be used in many applications where you need to create a watertight seal. Flat Roofs, Metal Roofs, Sloped Roofs, Planter Boxes, Foundations, Sheds, Basements, Metal, Wood, Concrete and more. Use Liquid Rubber Seam Tape or Liquid Rubber Geo-Textile to bridge seams, joints, vents, protrusions to create a long lasting repair or rejuvenation. Apply when temperature is above 40F/5C. Apply to a dry surface, free of dirt, loose flaky paint and coatings, oil, grease, coal tar or other contaminants. Typically cures within 24-48 hrs. Do not freeze. Store in a warm area. Do not apply in wet conditions or if rain is forecasted within 24 hrs. Not meant as a constant walking surface. Coverage - Vertical Surfaces - Apply a minimum final thickness of 1 gallon/30 sq ft (2.8 sq m). It should require around 3-4 heavy coats to achieve a 30 mil (0.76mm) (DFT) membrane. Flat/Ponding Surface - Apply a minimum final thickness of 1 gallon/15 sq ft (1.4 sq m). It should require around 4-5 heavy coats to achieve a 60-80 mil (1.5-2mm) (DFT) membrane. Apply next coat when dry to touch and nothing is wet underneath; tacky is okay. Generally 12-24 hrs between heavy coats. Amounts vary depending on surface roughness. Use all material up to achieve a long lasting membrane. Avoid hot, direct, intense sunlight during application. Remove Painters Tape while still wet. Membrane will turn brown in ponding situations due to surfactants. Will dissipate over time as the water cycles and cleans. Clean Up - Use soap and water or mineral oil to clean skin. ## Features - PROTECTIVE FINISH FOR - Flat roofs, metal roofs, sloped roofs, planter boxes, foundations, sheds, basements, metal, wood, concrete and more - HIGHLY FLEXIBLE and DURABLE - Final membrane has over elongation preventing adhesion failure, and is UV Stable stopping the sun from degrading the product - COVERAGE - Vertical Surfaces - 1 gallon/30 sq ft (2.8 sq m).3-4 heavy coats to achieve a 30 mil (0.76 mm) membrane.

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 on Reviewed in the United Kingdom 21 August 2026* Excellent done the job perfectly ### ⭐⭐⭐⭐⭐ Wow, this stuff seals and lasts *by on Reviewed in the United States 21 July 2026* 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….. ### ⭐⭐⭐⭐⭐ Paint *by on Reviewed in the United Kingdom 29 May 2026* Good quality ## Frequently Bought Together - Liquid Rubber Waterproof Sealant – DIY Leak Repair Coating for Flat, Metal & Low Slope Roofs, Foundations, Gutters & More – Flexible Protective Membrane - Black - 1 Gallon - Liquid Rubber Geo-Textile - Fix Leaks - Repair and Restore - Easy to Use, 4 Inch x 160 Foot Roll - Liquid Rubber Caulk - Hybrid Adhesive and Protective Sealant, White, 4 Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/303831937-liquid-rubber-l-r-waterproof-sealant-original-black-1-gallon](https://www.desertcart.co.za/products/303831937-liquid-rubber-l-r-waterproof-sealant-original-black-1-gallon) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-17*
