THIS PRODUCT IS NOT AVAILABLE FOR SALE IN CALIFORNIA
Polyprene® is a rubber, universal roof repair cement used for flashings, seams, pitch pans, cracks, splits and making various repairs on EPDM/PVC/TPO roofs. We offer a special Polyprene® with extra agents that provide maximized adhesion specifically for EPDM/PVC/TPO roof repairs. Polyprene® for EPDM/PVC/TPO offers a water-tight and long-lasting seal. The heavily-fibered, high-solids content prevents mud cracking, making it ideal for pitch pans as well as to seal seams, cracks, around vibrating rooftop equipment, skylights, vents, flashings, and more. Polyprene® for EPDM/PVC/TPO is available only in heavy brush grade.
- Quickly and easily reinforces critical areas
- All rubber, fiber reinforced — stays flexible and won't crack when cold
- May be used with or without PolyCore™ reinforcement, as needed
- Can be applied thick, in one layer, without threat of mud cracking
FAQs
Q: How do I fix blisters in my roof surface?A: Fix blisters by making an “X” cut, laying flaps open to clean/dry out, then fill and tamp closed and add more Polyprene® to cover all edges.
Q: What do I do if I have seams with a larger than 1/16” width?
A: When working with Polyprene®, gaps being sealed should be no more than 1/16” in width. However, we have a strong solution for larger gap sealing. PolyCore™ membrane nap can be applied to cover original gaps of more than 1/16” before applying Polyprene®. This reinforces the gap and allows for a clean, water-tight seal.
