The Con-Tact Brand Under Sink Mat provides a great solution for the kitchen or bathroom. The cabinet area under the sink can be exposed to moisture from dripping plumbing and leaking cleaning chemical cans and bottles. The Con-Tact Under Sink Mat is a solid vinyl material that moisture and chemical cleaners cannot penetrate. The mat protects the wood cabinet shelf which, in many cases, is made from particle board. When particle board gets wet, it swells and over time starts to come apart. The mat protects the wood from detergent and chemical stains. The Con-Tact Brand Under Sink Mat is non-adhesive. It measures 24 x 48 inches. Simply cut it to fit the size of your under sink shelf.
