A fast-drying, high-viscosity EPDM and TPO membrane primer that promotes uniform coverage. Intended for use with seam and splice tapes, cover tapes and self-adhering flashing. Primer does not react with atmospheric moisture allowing it to be opened and resealed for use at a later date.
How to use Seam Tape Primer:
Rubberall EPDM Tape Products will not adhere or perform overtime if Seam Tape Primer is not used.
As a consequence, the primer must be applied with a Rubberall 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 of Seam Tape Primer: 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 the only bond the surfaces when the primer is dry to the touch.
