Removing Creases from EPDM Membrane
In this tutorial, we’re going to show you how to effectively remove creases from EPDM membrane.
Step One
Lay out the creased EPDM membrane and smooth onto a flat working surface.

Step two
Using a heat gun, gently heat up the surface of the EPDM membrane and smooth out the creases using a silicon roller.

Take care not to burn the EPDM!
Step three
Work quickly and efficiently across the creased area without remaining in one place for too long.

IMPORTANT: Only use a heat gun, never a naked flame!
Step four
Apply gentle, yet firm and consistent pressure to the roller to remove the creases.

Step five
Flip the EPDM rubber membrane over.
Step six
Apply bonding adhesive to the membrane underside, and to the roof substrate.

Step seven
Wait for both surfaces to tack off, before using the silicon roller to fully secure the membrane to the substrate.

And you’re done.
