Review: SHADES OF GREY - Here is my updated review of FLEX SEAL GALLON GREY product I 1hammer1 am changing my negative review of FLEX SEAL Liquid 128-fl oz Gray Dip Rubberized Coating. The SAME day that I published my negative review of this product THE FLEX SEAL COMPANY called me at home and offered a solution to my problem with the grey color WOW they wasted no time they have made me more than happy ( WHAT A GREAT COMPANY ) I have always liked their products the FLEX SEAL Liquid 128-fl oz Gray Dip Rubberized Coating is a great water proofer we have had water in our basement when it rained hard. We have done our whole basement walls and floors with this product this product will and does stand up to hydrostatic water pressure if it is applied in 2 to 3 coats, BUT we were told it probably would not stand up to normal foot traffic in our basement (NOT TRUE) we have scooted and pushed and walked all over the floor no problem unless you really scape hard on the floor but you have to apply this product properly clean the surface have no loose stuff and dry and apply 2 to 3 coats let dry well 2 to 3 days between coats also ventilate the area well. We had basement waterproofing estimates between $30,000.00 and $42,000.00 this product cost near $100.00 per gallon and we purchased 29 gallons from 1 source and 8 gallons from another source total =37 gallons est. cost $3,700.00 ( WOW BIG DIFFERANCE ) My wife and I are 80 years old and we did all the work by our self's we just took our time also after the 1st coat you do not have to wait till it is not raining to appy more coats because it stops the water from coming in, apply more coats for stronger protection and longevity I truly do recommend this product and truly recommend the FLEX SEAL COMPANY and special thanks to Ashanti Mckissic Customer Care Manager Swift Response, LLC for their super fast response to our grey color problem again thank you FLEX SEAL P.S. There are several other company's out there that could take some honesty lessons from FLEX SEAL xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx old review We have several different shades of Flex Seal Liquid grey in our basement now and we paid you almost a $100.00 a gallon here we are 29 gallons later with different shades of grey in our basement on our floor and walls we purchased these at two at a time and sometimes 4 at a time. There is no consistency of color sad.

I used the cheaper desertcart Water Sealer version previously and it leak after 1 year. ## Features - Flex Seal Liquid is liquid rubber in a can!

There is no consistency of color sad. ### ⭐⭐⭐⭐⭐ Stay Dried Forever *by D***V on 23 November 2025* Best product for my Patio Metal Awning which leaks after 5 years of installing from the installer using cheap outdoor caulking which cracked. I have had this on for 3 years and no signs of cracking. I used 1 gallon for each patio and put 3-4 coats on with 24hours in between. I used the cheaper Amazon Water Sealer version previously and it leak after 1 year. ### ⭐⭐⭐⭐ Review amendment, retraction, continue reading *by E***Y on 2 August 2023* Product was well packaged. once open, FlexSeal was dry, cured and hardened, was not usable, was not able to contact anyone, Amazon or the seller about being able to return a defective product. do not buy. buy local, at least you can return it, if something is wrong. I am amending my first review that was written out of frustration! the return process for this product is not standard and not done through amazon and is not as easy to navigate. The return/complaint must be done through the seller and therefore you have to figure out how to do that. once that was completed, I have to say that FlexSeal went way beyond what was necessary to satisfy the customer. They replaced the original defective product and added additional product in the shipment. In addition, i got an email from the company saying they were sorry for the inconvenience and gave me a refund on top of what they already did to correct the issue. above and beyond compared to most companies. I felt compelled to make the correction and a little bit like a jerk for my initial reaction. ## Frequently Bought Together - Flex Seal Liquid, 1 Gallon, Gray, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - 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 - Flex Tape, 4 in x 5 ft, Gray, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor Projects - Home RV Roof Plumbing and Pool Repairs --- ## 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.tn/products/254296113-flex-seal-liquid-rubber-in-a-can-1-gal-gray](https://www.desertcart.tn/products/254296113-flex-seal-liquid-rubber-in-a-can-1-gal-gray) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-28*
