European Red is composed of crushed brick dust and is ideal for top-dressing existing natural clay courts and ClayTech courts. It has also been used as a cap on top of existing Har-Tru courts to seal off the green and leave the fiery red/orange finish on display. This rich red product leaves its mark in a way no other surface can. Not just on the clothes and the ball but in the heart of a tennis player. You can purchase European Red Clay from 10-S Tennis Supply in 55 lb. bags. Please call for pricing.
