The improved top dressed synthetic turf according to the patent invention provides thatch like fibers to retain top dressing and particularly the rubber or resilient particles in the dressing. The grasslike surface is formed by polyethylene co-polymer slit fibers more than two inches in height tufted through a fiberglass reinforced backing. The thatch zone fibers are dense and texturized so that they will contract to only about one inch in height after curing.
