Liquid Roof®


LIQUID ROOF® is a true liquid EPDM rubber and therefore could be described as a liquid that when cured has all the characteristics and properties of the single ply EPDM membrane that has established an outstanding performance record for over 30 years. EPDM rubbers have the best aging properties (retains flexibility longer) of all the elastomers.



Before and After
on an RV roof

Liquid Roof® is used to extend service life, seal leaks, reduce interior heat and rain noise, and stop chalking on older RV roofs. Can be applied to metal, plywood, fiberglass, sheet rubber and fabric surfaces. Liquid Roof® is applied by squeegee, roller and/or brush.

Now you too can enjoy them many benefits of a weather-tight rubber roof. Liquid Roof's® simple one-coat application saves you time and money, sealing and protecting your motorhome from water damage and fuel guzzling drafts. Liquid Roof® is available in white and covers 40-46 sq. ft. per gallon.

Liquid Roof is not just a thin coating, when cured it is a whole layer of new EPDM rubber approximately 20 mil (20 thousands of an inch) thick.

NOTE: When cured, Liquid Roof® is the same rubber that is currently on your roof!

Liquid Roof® is resistant ot Ozone and UV (Ultraviolet rays from the Sun). It remains flexible and durable in the temperature range of -60ºF to 300ºF. It is not harmed by freezing or snow. It resists ponding (standing water after a rain), and is not damaged by salt water, acids and alkalis.

The white color of the cured rubber reflects heat in warm weather thereby lowering the interior temperature. Liquid Roof® becomes waterproof immediately upon application. Should it rain shortly after application, the appearance may be altered slightly due to rain, but this does not prevent it from fully curing when dry and above 55ºF.

It is highly recommended that you do not drive your RV until the coating is tack-free to the touch. For best results wait until fully cured, (3-7 days depending on temperature).


Liquid Roof® will not cure below 55ºF
Temperatures below 55ºF after Liquid Roof® has been applied will not harm it. The curing will continue when the temperature again rises above 55ºF.
