Abstract:
1. A method of coating a tufted, porous athletic turf backing having a top face and an opposing bottom face, and having yarn tufts that form grass blade-simulating piles projecting from the top face and parallel rows of backloops along the bottom face, the method comprising: selecting a coating material to bond the yarn to the backing; and spraying a wide-area shower of discrete droplets of the coating material over the bottom face in multiple spray passes, wherein, for each pass, the axis of spray is at an inclination angle of less than 45 degrees to the plane of the backing, sprayed coating material droplets discretely deposit against the bottom face, and sprayed coating material droplets deposit against the proximate sides of backloops, but are considerably shielded from depositing against their distal sides and over small areas of backing adjacent those distal sides.
