Abstract: A method and system for treating calcium-based stone having a surface to be treated for corrosion and stain resistance is provided. The system comprises a sanding unit to sand the surface of the calcium-based stone with a grit size of 40 to 100 to promote coating adhesion. The system further comprises a coating unit to coat the surface of the calcium-based stone with a predetermined amount of a coating material for corrosion and stain resistance defining an uncured coating on the surface. The system further comprises a curing unit to cure the uncured coating on the surface with a photo-initiator defining a cured coating on the surface. The system further comprises a polishing unit to polish the cured coating on the surface with a grit size of 1000 to 3000. The system further comprises a buffing unit to buff the cured coating on the surface with a fabric defining a treated surface of the calcium-based stone.
