FAQs About Firestone RubberGard
1. What is EPDM?
EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e. ketones, esters, and alcohols).
2. What is the maximum size sheet for EPDM membrane?
Sheets as large as 50 feet in width are produced mostly for use in ballasted and mechanically fastened applications. Narrower widths are also produced to offer applicators greater flexibility in positioning membrane.
Narrower sheets are also produced without factory seams (seamless) for use primarily in adhered and mechanically fastened applications. The major advantage of seamless material is the elimination of factory splice T-joints that occur when factory seams intersect with field splices. This reduction in T-joints significantly increases the potential for watertight performance by eliminating potential "water channels" into field splices.
Both narrow and wide sheets are manufactured in varying lengths from 50' to 200'.

3. Are temperature limitations associated with the installation of EPDM roofing system?
In accordance with ASTM standard D 746, EPDM membrane has a brittleness temperature of -49° F. While the membrane will remain flexible and pliable in extremely cold temperatures, adhesives, flashings and tapes should be kept at room temperature (hot boxes are usually used on the rooftop to rotate adhesive cans and rolls of flashing). Although roofing contractors may select not to work in sub-freezing temperatures due to safety concerns, many EPDM installations have taken place in temps below 20° F.
4. Can EPDM be coated or painted?
Acrylic coatings are available that can be applied directly to a prepared EPDM surface. Preparation usually consists of cleaning the EPDM with a pressure washer and a detergent solution or wash. Latex-based paint products can also be used, however, the EPDM manufacturer should be contacted prior to application to ensure compatibility and continuation of warranty coverage.
5. How do I seam 2 pieces of liner together?
There are seam tapes like 3 inch double sided seam tape to seam to sheets of rubber together. There is also 6 inch and 12 inch flashing for detail work around vents, air conditioning and ventilation units and other large penetrations. There is also a rubber pipe boot for pipe penetrations that fits 1 inch up to 6 inch pipes.
