Shield It creates a water- and oil-repellent, microscopic, invisible shield. It is not a surface or barrier coating, instead, it deeply penetrates and chemically bonds with the substrate without altering its appearance. It allows the substrate to breathe. Shield It does not affect slip resistance and does not degrade with UV light or wear off in high traffic areas.
