Wooster’s innovative roller gauge system is designed to make spreading, gauging, and back rolling coatings easier. These patented end caps control the mil thickness of the coating being applied—essentially replacing the squeegee process. The roller gauges work with roof coatings, floor coatings, epoxies, urethanes, anti-skid floor toppings, vapor barriers, and metallic finishes. Use Wooster Roller Gauges with 3/16-inch nap Wooster paint rollers; please be advised that utilizing different nap height covers will provide varying results. They’re easy to use! Simply roll out the coating until the gauges emit a chatter noise on the floor. Each gauge is color-coded for quick selection.
