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.

      Overall, I am impressed with the results I obtained in using Liquid RV roof on my trailer. It was MUCH easier than replacing the membrane with new, and seems to have repaired my leaking roof, extending the life of my RV, as at some point, the cost of reroofing would exceed the RV’s value. Thanks in advance!

      My roof was in bad shape. I cleaned it and kept after it a few times a year. We bought the RV used, and there were signs of neglect when we bought it. It had been obviously sitting in the sun for an extended period of time without any care or maintenance. I was about to buy a sheet of EPDM and forego the labor intensive and very expensive task of replacing the sheet roof. Then I saw a video on Youtube for Liquid EPDM. So the research began. “This… Read more

      I was able to quickly find the 2 pictures I took after I patched the roof. I will continue to look for the before pictures, We have a flat roof with a channel down the middle that leads into a drain pipe system that has been our weak point area all along. Then we installed a sky light which was like adding gasoline to a fire. For years I was blaming the sky light that we installed. We even replaced portions of the sky light and sealed around it many… Read more

      The epdm rubber roof was easy to work with. I am very pleased after having a leaky roof that will be good for many years to come. Roof had mold on it so we first killed the mold with Clorox and water and scrubbed I down and then cleaned the roof with Dawn dish detergent. Attached are the before and after pictures. ThanksRick M.
