Quickbond EPDM Primer/Seam Tape/Flashing Tape

Quickbond EPDM Primer is a solvent-based primer designed to clean and prime Rubberall EPDM Membrane. It should be noted that this is prior to the application of taped products.

Rubberall Seam Tape Primer is available in 250ml, 500ml and 1L. Therefore, the Rubberall Seam Tape Primer has an approximate coverage of

250 = up to 2m sq

500ml = up to 4m sq

1L = up to 8m sq

How to use:

• EPDM Tape Products will not adhere or perform overtime if Primer is not used. 

• As a consequence, the primer must be applied with a Scrub Pad to prepare the EPDM Membrane to receive the tape for the best adhesion.

• Finally, the solvent-based primer must be used in a well-ventilated area.

Key advantages: fast curing time, creates a stronger rubber-to-rubber bond, when used correctly, it prepares the membrane and substrate.

Primers are used to bond tapes and accessories to an EPDM rubber membrane. They are also used to clean and prepare rubber surfaces before using other various tapes. If it is not used, the surfaces will not be properly bonded together and your flat roof adhesive will have a shorter lifespan. You will also need to use a scrub pad on the EPDM membrane. This will scarf the rubber so that the two surfaces (rubber-to-rubber or seam tape) will adhere together to create a strong bond. When applying the primer, ensure that you apply it evenly to avoid pooling, and only bond the surfaces when the primer is dry to the touch.
