Prevent tracking dust out of the work area! The mat's adhesive surface captures dust on contact – simply peel away the top sheet to expose a new surface! Each ZipWall® Mat Starter Kit features a durable, reusable, non-skid base and includes a pad of 30 clear adhesive sheets. The base is 25″×37″ and the mat is 24″×36″. Slip-resistant backing holds the base firmly in place on carpeted floors and on smooth floors like vinyl, concrete, and tile. The base is portable and does not damage the floor surface. Adhesive sheets are individually tabbed and numbered so you always know how many are left. When the top sheet gets dirty, simply peel it off to expose a clean one. Large adhesive surface removes dust from shoes, casters, and wheels. A 4-pack refill of 30 sheets each is available. The EPA recommends the use of tacky mats to help comply with its Lead Renovation, Repair and Painting Rule (RRP Rule), which requires that renovation firms use precautions to ensure that all personnel, tools, and other items are free of dust and debris before leaving the work area. According to the EPA Inspection Manual for the RRP Rule, “tacky mats may be put down immediately adjacent to the plastic sheeting covering the work area floor to remove dust and debris from the bottom of the workers’ shoes as they leave the work area.”
