SonicBonded Mat Roll controls spills and overspray to help keep floors dry and safe. SpunBond top layer allows for better-defined perforations and cleaner, easier tear-offs. Ultrasonic bond points fuse layers of fibers together — Mat keeps its shape even when completely saturated. Top layer of lint-free SpunBond fabric provides extra strength. "Dimples" add fast-wicking power. Roll is perfed every 7.5" vertically and 17" horizontally. Heavy weight roll absorbs about 55.2 gal. per package. Measures 30 inches x 150 feet.
