3 Inch EPDM Seam Tape
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)
What is The Life Expectancy of EPDM Rubber Roofs?
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.
Can EPDM Withstand Hard Impacts From Outside Conditions? Such As Branches Falling On It Or A Bird Pecking On It?
Along with a life expectancy of 50 years and beyond, EPDM rubber can stand up to quite some force from outside elements, in our video below we explore what different objects falling on the rubber will do to it and how much damage it takes to actually penetrate the membrane! Prepare to be surprised!
How Long Does It Take To Install A ClassicBond Roof?
Generally, installing a ClassicBond roof can be a very quick job if you have basic knowledge about the preparation and the correct steps to take.
Some factors will affect the installation time such as the current substrate, size and type of roof; along with if there is any detail work required such as skylights.
Our friends over at RoofScout have made a great video showing you exactly how long it takes to install ClassicBond on a freestanding, timber-boarded log cabin.
For Sam, it took him just under a 1hour and 30minutes. He did install this roof alone and installed edge trims which make a difference to the installation time.

Is Classicbond EPDM BBA Certified?
Yes. ClassicBond EPDM holds the British Board of Agrément certificate, No. 11/4853, issued to Flex-R Ltd. The BBA carries out assessment, testing, approval and certification of products and systems for the construction industry against national requirements, internationally recognized standards or other relevant technical specifications, reviewed and reissued every 3 years.
The ClassicBond system is also fire rated, the 1.2mm EPDM has a fire rating of EXT.F.AB and the 1.5mm EPDM membrane is fire rated to EXT.F.AA. Fire rating is carried out on a variety of deck surfaces and it is important to seek the certificate that relates most accurately to your roof structure.
What Temperatures Can A Rubber Roof Be Installed In?
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.
