The new Runyon Wet Slick polishing pads are 9mm thick tools ideal for (as the name suggests) wet polishing. These tools are designed to be run under a heavy grinder or power trowel machine. Life for these tools is on average 40,000-60,000 on good, medium hardness concrete. This ultra flexible tool series is made in Bulgaria. The Wet Slick’s unique face design features large channels, which allows water and debris to pass through easily.
