EPDM is the acceptable abbreviation for Ethylene-Propylene-Diene Terpolymer, a synthetic rubber compound that gives high-performance waterproofing when laid in a single piece of membrane over a flat roof surface.
The membranes offer unrivalled resistance to UV radiation, ozone, alkali rains and exceptionally high or low temperatures. Studies have demonstrated that genuine Firestone membrane has an expected lifespan of more than 50 years.
No, the membrane is only available in slate grey. It can be painted with a suitable acrylic paint in some circumstances.
No, the membrane is only suitable for roofs and gutters. EPDM pond liners are available, but are manufactured using a different process to the roofing membrane.
Yes, it is possible to ballast the membrane, but you must take care to cover the membrane with a suitable medium, such as rounded washed bank river gravel and/or pavers placed on protective rubber feet.
Firestone RubberCover EPDM is a 100% cured single-ply roofing membrane manufactured from synthetic rubber compound. Its full name is Ethylene-Propylene-Diene Terpolymer.
No. If the membrane is excessively dirty, however, it can be cleaned with ordinary water and a clean rag.
Firestone QuickPrime Plus primer must be used with ALL Firestone Quickseam products in order to clean and prime the membrane before application.
Yes, but check the underside of footwear for sharp objects that may puncture the membrane.
Other than a recommended annual visual inspection of the roof, No. Once installed correctly, no specific maintenance is required for a Firestone RubberCover EPDM roofing system.
Other than sharp materials, the membrane is less resistant to oil or oil-based products. Contact with certain oil-based products should be avoided.
EPDM membrane is super-tough, yet in the unlikely event of damage, it can be effectively repaired. Different areas of damage will require a different focus for repairs.
You should always apply bonding adhesive to both surfaces - roof deck (or board) and membrane.
Yes. The surfaces will be ready to be mated together after the adhesive is applied and has flashed off. If the prepared surfaces are left open longer than necessary, debris may contaminate the surface area, or temperature fluctuations may impair application.

EPDM membrane can be adhered to different substrates, such as OSB3 sterling board or plywood timber. Smooth concrete and tissue-faced insulation boards are also suitable, but note that new concrete should be fully cured before membrane installation.
No. The surface of the roof deck must be fully dry and free of ponded water, snow, frost and ice before installation of the membrane can take place.
Yes. The surface of the roof deck must be swept clean, and be free of sharp and/or loose particles, fasteners, debris and/or foreign materials that could puncture the membrane.
No, there is no difference between the top and bottom of the standard and premium-grade membrane. Fire-rated (FR grade) membrane does have an up-and downside. There is clear wording stating which side this membrane should be laid.
No, the membrane is resistant to UV rays and ozone and requires no protective top coat.
Yes. Although it can be fitted in the rain, the minimum temperature for application of the adhesive is +5ºC and maximum humidity is 80%.
Not allowing the adhesives enough 'flashing off' time can lead to solvents in the adhesives causing bubbles or wrinkling. The wet adhesive distorts the membrane and causes a ripple-effect.
Yes. There are just a few tools required for installation of EPDM rubber roofing systems.
The use of double-skinned penetrations is required.
Yes, we recommend a range of precautions.
