Method for coating a tufted athletic turf backing

A method for coating an artificial athletic turf made of a backing having a top face and a bottom face and having yarn tufted through the backing such that cut pile extends from the top face and backloops of yarn are closely adjacent the bottom face so that a porous coat is disposed over the backloops and bottom face in order to bind the yarn to the backing. Tiny droplets of coating material are sprayed onto the bottom face of the tufted backing at an inclination angle of less than 45 degrees to the plane of the backing and under conditions which cause sprayed droplets of material to bind the backloops to the backing, but not deposit along narrow areas of the backing between rows of backloops, thus, allowing the turf to remain porous.
