Coverstock is only on the top side of the absorbent pad to allow pad to instantly begin soaking up liquid, keeping the pad firmly in one place and still having the durability of the EverSoak® line of absorbents. Store near potential leaks, drips and spills in order to act fast and keep work areas safe from potential slip and falls due to fluid on the ground. CAUTION: Not intended for use with aggressive acids or caustics. Dispose of all absorbent materials in accordance with local, state and federal regulations.
