EPDM Primer is a rubber polymer water based roofing primer, and like its name; its been specifically designed for EPDM surfaces. EPDM Rubber is extremely hard to stick to without a quality Primer. This Primer does not react with atmospheric moisture allowing it to be opened and resealed for use at a later date.
Apply a minimum final thickness of 1 gallon per 250 sq ft (23.23 sq/m).
All work surfaces should be clean, dry; free of dirt, dust; debris, oils; un-adhered coatings, deteriorated membranes and other contaminants that may result in a surface that is uneven or not sound. Clean the surface with Liquid RV Smart Cleaner and wipe down with acetone prior to the application of the Primer.
- Do not use as a membrane cleaner.
- Talc, dust; oil, ice; snow or wet conditions inhibit good adhesion. Clean and dry surfaces are a necessity.
- Not to be used on TPO and PVC roof membranes.
- Install above 10C (50F) and rising
- Do not apply later in the day if Rain or Dew is forecast

Data Sheet & Safety Data Sheet
First ordered through Amazon. Waited and waited and ... after more than a month was told it was lost. Then ordered direct from Liquid Rubber website for the same price and received it two days later. Kudos. Have yet to use it.
Good easy to apply. Took three coat by roller to get pail empty.
Better have a good weather window. Only got one coat on, then had to abort. Still waiting for another weather window.
EPDM roof was badly worn out. Purchased cleaner, primer and Liquid rubber roof and it looks like new now. Cleaner was excellent and made that part of the job easier than other products I have tried. Excellent products and results.
all products(waterproof coating, epdm primer, geo-textile) were very good & technical service was excellent
