With a larger particle size, this surfacer gives players a clear visual and physical warning that they are nearing the fence. The 3/8” minus particle size also allows for the best drainage of the three warning track blends. This mix is preferred by teams who want to have a distinct ‘crunch’ underfoot as an indication that the fielder is nearing the wall. The Warning Track Surfacer comes in Mar-Co’s signature red colour, giving your ball field a professional look.
