The formulation behind Keratrax MS has been used to manufacture synthetic equestrian surfaces for more than ten years. The expected lifespan is highly dependent on the level of maintenance. The wax itself will not ‘dry out’, however if organic matter is allowed to contaminate the surface, or water containing silt is used to water it, the whole surface will appear to dry due to the large increase in surface area of the particles and the absorbent nature of organic materials.
