For Step-By-Step Guides Specific to Your Project
Precut Seam Tape to desired length and fit. Remove plastic backing before applying (be careful not to stretch the seam tape when removing the backing).
Apply Seam Tape to all seams at perimeter and protrusions (vents, skylights, etc. Use pressure to activate adhesive leaving no wrinkles or fish-mouths. Overlap separate pieces of Seam Tape by at least 1 inch.
Prime detail roof areas (not the Seam Tape) with the EPDM & TPO primer. When dry (tacky when cured), apply a heavy detail coat of RV Roof Coating over the Seam Tape to encapsulate (at least 1 inch beyond the edges of the Seam Tape). Allow to dry.

Haven't used the product yet
Hey Andrew, Great to hear that your project was a success!
It only good for flat surface if there is few small bumps it will not glue with the bumpy profile it will pull away from the rubber next few dsys
The Seam Tape should conform to small bumps, but If it didn't bond then there may be some type of contamination on the surface or an existing product like silicone. The Seam Tape will not bond to silicone.
Great product and easy to apply. Holding up so far and providing water proof that is needed!
