Abstract: First and second mat sections are interlocked using a resilient closure strip. A layer of reinforced vinyl scrim is situated on the surface of each mat section. The closure includes two closure members each having an interengaging portion and a connecting portion. The connecting portion of one closure member is mounted on one mat section with the interengaging portion in a given orientation. The connecting portion of the other closure member is mounted on the other mat section with the interengaging portion thereof in an orientation opposite to that of the first interengaging portion with at least a portion thereof extending beyond the mat surface such that the interengaging portions align and can be interengaged by a downward force when the mat sections are situated in side-by-side relation. A coating of poly-vinyl paint is situated over each of the closure members and the reinforced vinyl scrim layer.
