Slick-pack is a dry powdered pump primer and pumping aid packaged in a patented, ready-to-use, water-soluble bag. Slick-pak is uniquely formulated to provide the concrete pumper with a cost-effective replacement for premium priced grout, primer slurries or bagged cement primers. Additionally, slick-pak functions as a concrete pumping aid by reducing line pressure, which enables the placement of hard to pump mixes and increasing the range of pumpability. Slick-pak is also environmentally safe and compatible with all conventional concrete materials. Slick-pak contains no bentonite, cementitious materials, soaps or air entraining agents.
