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.

      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.

    • Staff at EPDM Coatings,

      My 29, RV had a couple leaks, at the front where the aluminum and rubber roof came together under a molding, and under the radio antenna. I purchased the 5 gallon bucket. I mixed as directed, then poured mixed product into another clean bucket, scraped it clean, and mixed a few more minutes. After preparation, I applied the liquid rubber around all edges and roof fixtures, I poured small amounts out of the bucket onto the roof and distributed with squeegee or roller as needed, until product was gone and… Read more

    • Hello,

      My name is Jeremy Berkheimer and I purchased the liquid roof coating earlier this spring. I am attaching the before and after photos of my 38 sandpiper roof. This coating was awesome. It took some real cleaning before hand and a I got a bit of extra exercise spreading it but the finished product seems well worth it. Thanks!

    • Hi

      Please find attached before and after photos for my camper roof. I forgot to snap a pic of the before, so I had already started applying the Proflex primer when I took the picture. You can still see the condition of the roof though! Also, the after pic was after the newly coated roof endured it’s first rainfall.
