Pumping concrete puts a lot of strain on the equipment, especially if the concrete is a harsh or complex mix. The more you can do to improve the performance, efficiency, and durability of your concrete pump, the less likely you are to need expensive repairs. That’s where Fritz-Pak Slick-Pak can be very useful. This high-viscosity concrete pump primer has been shown to reduce wear and tear on pumping equipment by lowering line pressuring and lowering the risk of a concrete plug in the line during the job. When properly mixed, Slick-Pak improves the pumpability of concrete. Since its creation over 20 years ago, Slick-Pak has become THE standard for concrete pump priming admixtures. The unique formula is formulated to evenly coat the inside of the pipe in a thick, gooey material that will allow the concrete mix to flow through the pipe without drying out. And it comes packaged in our signature water-soluble bag for easy dosing and use at the job site.
