3M Nomad Ultra Clean Matting 4300 is a disposable, dust collecting floor mat consisting of 40 sheets coated with a pressure sensitive adhesive. High tack surface removes dust and small particles from shoe soles and trolley wheels. When the top layer is contaminated, it is then simply peeled off to expose the next fresh adhesive layer ready for immediate use. The mat can be laid directly onto any clean floor surface and being low profile it does not need any edging or frame. It is designed to help protect clean areas where cleanliness and hygiene are critical factors.
