Technical Specifications of Liquid Roof and Liquid Rubber


Liquid Rubber is designed as an easy-to-apply process and boasts a weatherometer-200 hours. It has a pot life of 4 to 10 hours depending on the temperature. Cure rates are dictated by availability of oxygen and temperature, but—assuming curing is available—it requires 18-42 hours to touch and 48-54 hours to walk on. If Liquid Rubber is allowed to cure uninterrupted, it takes 3-7 days for a full cure.

Both Liquid Rubber and Liquid Roof require a temperature of at least 55° F in order to cure. If temperatures drop below that temperature, the curing will stop and re-start once 55° F+ temperatures resume.

Liquid Rubber and Liquid Roof strongly resist acids, polar solvents and alkalis by utilizing a two-component curing system that’s kickstarted with a heat resistance of 302° F.

Keep in Mind: Mixing the Catalyst and Liquid Rubber

Remember that curing requires both a minimum temperature and oxygen. Oxygen initiates the catalyst for peroxide decomposition. How quickly your application cures depends on the temperature. However, even if temperatures fall below 55° F, the end result will not be impacted.

What is Liquid Rubber?

Liquid Rubber is truly the liquid version of EPDM, and the physical properties are similar. You get the benefits of traditional EPDM like a great resistance to water damage and penetration. Liquid Rubber also stands up to UV and ozone damage and has fantastic anti-aging properties. This product can withstand temperatures that range from 300° F to -62° F, so it’s suitable for almost any environment. It easily handles ponding water and resists both acid and alkali. When spreading Liquid Rubber, the ideal rate is 20 mil. dry film at 42 sq. ft. per gallon for smooth surfaces. You can expect one gallon of mixed product to weigh 8 pounds, have an elongation of 180-200%, a brittle point at -62° F and tensile at 680 psi.

      EPDM is amazing. My RV roof was a disaster. I have been battling leaks for a few years now and no other product would stop the leaks or even last more than a few months. Everything else would peel up after awhile. I used the EPDM with the primer. It rained a week later. Zero leaks! The product goes on easy and covers well. No cracks no bubbles. I am very satisfied and would recommend this product to anyone. The are so many products out there and skepticism runs high…. Read more

      Just a great product, went on easy and looks great. Just completed my 35 Bus, cut in the rap around sides and around the ACs and vents. Spent the hardest time on cleaning and prep. If you are looking for a product to seal your RV stop looking !!!! David R. DLincolnton GA

      Let me tell you this stuff if fantastic. I replaced my roof several years ago and white rubber was not available at the supply company, it was out of stock and I had to replace the rubber as I had ripped the old off. The black rubber made it miserable in here. I did a lot of research looking for a good quality coating that would last and hold up to the elements. I found your product and was convinced, so I ordered and have now applied. I did not… Read more

    • 5000 sq ft concrete roof

      5000 sq ft concrete roof. Prep work consisted of power wash of roof and preparation of seams as see in “before” picture. Approximately 7 sets of ProFlex primer was used and 28 Pails of Liquid EPDM Rubber. Cost per sq ft approx. $1.66 . Life expectancy is 18-20 before a recoat is needed.

    • Kim Stonecipher-Furr

      Hello Greg, Here are the photos, three before, during and after per your request: I will say that your product surpassed our expectations and saved us a huge $7,000 new roof cost. We had no leaks and but were informed during a free roof inspection that we needed a new roof by a local rv establishment. I discovered your website and bought your products just to be on the safe side. We applied the primer as well as the liquid roof. It is definitely something that both genders are able… Read more
