Firestone Quickprime Plus is designed to clean and prime the EPDM membrane prior to application of Quickseam products. Quickprime Plus must be applied with a Quickscrubber Pad and Handle.
Preparation - Surfaces to be primed must be clean, dry and free of foreign materials, talc and dirt. Pre-cleaning with Splice Wash may be required. Stir Quickprime Plus thoroughly before and during use. When exposed to lower temperatures for a prolonged period of time, restore to room temperature prior to use. Pour the required amount of Quickprime Plus into a bucket for ease of application.
Application - Apply Quickprime Plus to the EPDM membrane with a Quickscrubber Pad and Handle, using long back and forth strokes with moderate to heavy pressure along the length of the area. Continue until surfaces become dark grey in colour (no streaking or puddling). Factory seams require parallel as well as perpendicular application motions along the factory seam. Allow the primed surfaces to dry completely according to the touch-push test (usually less than 10 minutes) before applying Quickseam products (3" seam tape, 6" batten cover strip, 9" formflash etc)
