The present invention relates to a polyurethane surface and more specifically to a polyurethane surface derived from the catalyzed reaction of equivalent volumes of a polyisocyanate component and an active hydrogen component. The two-component system achieves optimal gel time and cure response for application as an athletic surface having an isocyanate index between about 105 and 115. Moreover, the present invention achieves these results with a 1:1 by volume two-component system, which minimizes mixing errors during application of the surface.
