The basic principal of SandFree® is to chemically bond a coat of urethane to the existing surface.  The bonding chemical can be clear or colored.  That means we can apply the same process to concrete!  We can change the colors of the concrete and easily apply a protective coat of finish.  Warehouses, garage floors, all concrete surfaces can be recolored and protected, at very low prices.
