Does natural stone require sealing?
By its nature, a stone surface is porous. Absorption may result in discoloring or staining. Immediately after installation, the granite countertop is sealed. The sealer penetrates the stone, clogs the pores and creates a virtually impenetrable surface that resists absorbing alcohol, juice, soft drinks, coffee, food, oil, cosmetics and cleaners. With proper care and commercial grade cleaners, it is easy to maintain the original luster for years.
