METHOD AND APPLICATOR FOR FIELD APPLICATION OF ANTI-SKID OR DECORATIVE AGGREGATE COATINGS

摘要

An applicator for applying an aggregate coating to a substrate includes an apparatus comprising a first hopper for supplying aggregate particles, the hopper in spaced relation to and above the substrate, first release means for releasing the particles from said first hopper along a first predetermined path that intersects the substrate at a first location, spray means for spraying a liquid binder material along a plurality of paths, including a second predetermined path and a third predetermined path, the second predetermined path intersects the first predetermined path above the substrate, and the third predetermined path intersects the substrate at a second location in spaced relation to the first location, and supply means for supplying the liquid binder material to the spray means; and, means for moving the apparatus in a first direction relative to the substrate. The method of the present invention includes positioning a particle supply above a portion of said substrate, the supply containing a plurality of particles, releasing the particles from the aggregate supply at a predetermined rate, allowing said particles to free fall towards said substrate, coating said particles with a liquid binder material as the particles free-fall towards the substrate, thereby producing coated particles, coating a portion of the substrate with the liquid binder material, thereby producing a coated portion, and impacting said coated particles onto the portion of substrate.
