3 Inch EPDM Splice Tape
Used For: 3 Inch EPDM seam tape is used to join two pieces of EPDM membrane when it is not practical to complete the roof in one piece. e.g. "L" shaped Roof
Installation Notes:Ensure your two pieces of EPDM membrane that you wish to join are overlapping by 75 mm (3"). Fold back the top layer and apply Classicbond rubber primer to both surfaces. Wait until the primer is dry to the touch and then, leaving the backing film on the splice tape starting at one end stick the tape down onto the bottom EPDM membrane.
Use your hand to smooth down the splice tape ensuring there are no creases. allow the top membrane to fold back into position and then peal away the backing film pulling at a 45 degree angle while smoothing the top membrane over the seam tape with your hand. Use Seam Roller to apply pressure
Bonding to other surfaces: The seam tape can be used to join the EPDM rubber membrane on to both TPO and PVC roofing systems. The tapes are often used to repair damaged TPO and PVC as a cost effective alternative to replacing the whole flat roof. When joining the rubber membrane to uneven or granular built up roof surfaces, such felt or Asphalt, we recommend the use of a Termination bar and water cut off mastic (water block)

EPDM Rubber roofs have a 50 year life expectancy.
EPDM has been in commercial use since the 1960s. And many of those roofs are still around today.
Yes, EPDM Membranes require the substrate to be dry prior to installation. This is so the the adhesive & primers can effectively bond the rubber to roof deck. EPDM products will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of the membranes.
Yes, ClassicBond membrane holds the British Board of Agrément certificate, No. 11/4853 (issued to Flex-R Ltd). It also holds fire ratings for each of the thicknesses available.
We recommentd a minimum tempereture of 5 degrees C for EPDM installation. This is due the the WBA adhesive being water based and lower temperetures may cause the adhesive to freeze over and fail.
