This Firestone Quick Scrubber Kit includes everything you need when applying QuickPrime Plus during the seaming of two sections of EPDM liner. The kit contains 6 scrub pads and an easy-to-use holder. Simply attach the pads to the holder by using the small securing hooks on the bottom of the holder and start scrubbing the seam to allow the QuickPrimer Plus to fully grip the EPDM and provide a permanent seam for a leak-proof liner job..
