Some Technical Information on Liquid Roof and Liquid(R)

pricing_canimage

Weatherometer-2000 hours (ASTM D4459-8-03)

Pot Life-9;4-10 hours depending on temperature.

Cure Rate-(18-24) hours to touch;48-54 hours to walk on and 3-7 days full cure.

 

Liquid Roof and Liquid Rubber need temperatures above 55 degrees to cure. The temps can go below 55 but the product will not begin curing again until the temp’s go above 55 degrees.

Chemical Resistance-Cured EPDM rubber is resistant to acids, alkalis and polar solvents

Cure system-Two-component Peroxide initiated

Heat Resistance 302 degrees F (150 degrees C)

Mixing The Catalyst With Liquid Roof

 

Physical Properties

The physical properties of Liquid Rubber(R) are typical of its EPDM chemistry. The outstanding characteristics include:

Extreme high resistance to penetration of water. Ultra Violet and Ozone stable. Excellent long term aging properties.

Very broad temperature tolerance range (from 300 degrees F to minus 62 degrees F). Acid and alkali resistant

Withstands ponding water even when not cured

Spreading Rate A 20 mil dry film will result when liquid is applied at the rate of 42 sq. ft per gallon on a smooth surface.

A rate of 45 sq. ft allows for average roughness.

Weight/gallon 8 pounds (mixed)

Tensile 680 psi

Elongation 180-200%

Brittle Point -62 degrees F

Cure Mechanism-This rate is determined by temperature and the availability of oxygen. Oxygen is necessary to activate the catalyst, which promotes peroxide decomposition at lower temperatures. The cure mechanism in EPDM Liquid Rubber(R) will vary from active to inactive determined by temperature. Broad day-night temperature swings in spring and fall will not compromise the final physical properties of the Liquid Rubber(R) membrane.

      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.

      Hi Everyone, I completed my project and it was much easier than I thought, I wish I had done this years ago, and glad I chose this coating versus the other offerings out there. I will send you 2 more emails, this is the start of cleaning, next is primer, the third is the coating. Hope they are worth of a gift card. Thanks
