Hard courts
Hard courts, usually made of cement or plastic, are considered "fast" surfaces, where fast, low bounces keep rallies short, and powerful, hard-serving players have a slight advantage. Hard courts can vary in speed, but they are faster than clay and slower than grass courts, which allow the ball to slide. These courts are considered the most equal for all playing styles. The US Open is played on DecoTurf, an acrylic hard court, while the Australian Open is played on Rebound Ace, a synthetic hardcourt.
The main difference between Rebound Ace and true hardcourt surfaces is the level of hardness. Rebound ace is softer (more spongy) . Consequently, when the ball bounces on this surface a large part of the ball's momentum is absorbed by the surface and reduces its speed. On a hard surface the loss of momentum is negligible because the surface provides less cushion to the bouncing ball.
The amount of sand used in the top paint also determines the speed. More sand means less speed. The amount of friction can also be altered and more friction will produce a clay court effect, where topspin is magnified. The extra grip/friction will resist the sliding effect of the ball and the resistance will force the ball to change its rotation. The extra grip provided by the surface is also dangerous because it can resist the movement of the player and can cause injury.
The ITF classifies Rebound Ace as a type two category (medium/medium fast) hardcourt.
Plexicushion
The Plexicushion substrate, a special blend of latex, rubber and plastic particles, forms a resilient layer that absorbs body shock and reduces muscle fatigue. The 100% acrylic Plexipave Surface provides consistent and uniform bounce, long lasting color, and allows speed of play specification. Plexipave Sport Surfacing Systems use recycled and post-industrial components in each of the formulations. This manufacturing choice minimizes the exploitation of petroleum and wood resources. The Plexicushion Prestige System (liquid) contains 16.5% of post-industrial or recycled products.
Plexipave
The Plexipave Color Finish System is an all-weather, durable, quick drying color surfacer that provides superior resistance to deterioration from ultra-violet rays. Plexipave is a 100% acrylic latex, color intense sports surface formulated for use over asphalt and concrete. The high performance finish coat is ideal for tennis courts, basketball courts, play areas, multi-purpose sport surfaces, light traffic pathways and walks and field houses. The Plexipave Color Finish System is available in ten popular standard colors. Custom colors are available to meet individual needs. Plexipave has been the choice of tournament installations around the world.
