How to use:-
Before you apply your Premium Grade Rubberall Seam Tape, ensure that your two pieces of Rubberall EPDM membrane that you wish to join are overlapping by 3”/75mm. You have to fold back the top layer and apply the Premium Grade Rubberall Primer Plus to both surfaces and wait until the Primer is dry to the touch. Leaving the backing film on the Seam Tape, start at one end sticking the tape down onto the bottom piece of Rubberall EPDM membrane using your hand to smooth the tape down ensuring there are no bubbles or creases. Then allow the top EPDM membrane to fold back into position and then carefully peel away the backing film pulling at a 45 degree angle while smoothing the top membrane over the seam tape with your hand and for extra pressure, use a Seam Roller.
The Premium Grade Rubberall EPDM Seam Tape can be used to join the EPDM rubber membrane on to surfaces such as TPO and PVC roofing systems and can also be used to repair damaged PVC or TPO roofs which can prove extremely cost effective rather than replacing the whole Flat Roofing system. If you are adjoining the Rubberall@ EPDM membrane to Asphalt for instance it is adviced that you use a Termination Bar with Rubberall Water Cut Off mastic.
