A non-skid decorative plastic floor covering comprised of a decorative plastic base having a plurality of slip-resistant elements positioned on the base with a clear or translucent wear layer overlying the slip-resistant elements and the exposed intervening base. The slip-resistant elements comprise particles, preferably inorganic and rounded, embedded in a cured plastic matrix, the particles being distributed throughout the matrix in a substantially abutting relationship with the upper-most layer of particles protruding from the matrix such that the protruding particles impart a rough, irregular non-skid surface texture to the wear layer overlying the slip-resistant elements.

A method of manufacturing a non-skid decorative plastic floor covering comprising: (a) providing a plastic base as a liquid matrix; (b) applying elements in a preselected pattern to the base, said elements being of a depth and breadth such that when elements are applied to the base and embedded therein, there is curable base material in an amount sufficient to bind together the elements embedded in the base material in substantially abutting relationship but in an amount insufficient to cover the uppermost layer of elements allowing these elements to protrude from the base material; (c) said elements are rounded inorganic quartz particles and have a Moh hardness greater than about 4 and a particle size distribution such that none are greater than about 715 microns, about 80% are between about 300 and 595 microns and none are smaller than 150 microns; (d) embedding said particles throughout the base material in a substantially abutting relationship with the uppermost layer of particles protruding from the base material; (e) curing the base material; (f) applying an overall clear or translucent curable wear coating to form a continuous film over the cured base material having the protruding particles in an amount such that a rough skid-resistant texture is imparted to the coating by the underlying protruding particles; and (g) curing the wear layer.
