The Wooster Brush Co. has added a green, 16-millimeter roller gauge to extend its product line. These tools make a challenging application—controlling mil thickness—more precise. Their design helps with spreading, gauging, and backrolling roof and floor coatings, epoxies, urethanes, anti-skid floor toppings, metallic fin- ishes and vapor barriers. The four roller gauges in the line are color-coded to the dif- ferent mil-thickness depths they’re designed to achieve; the colors are yellow, 4 millimeter; red, 12 millimeter; green, 16 millimeter; and blue, 22 millimeter. Wooster-exclusive roller gauges are recommended for use with 3/16-inch nap Wooster roller covers; using different nap-height covers will provide varying results.
