Are overlays resistant to stains and spills like oil and grease?
Yes, once the floor or any surface is sealed the surface can be impervious (not allowing entrance or passage) to many chemicals including: salt, petrochemicals, UV radiation, and water. This makes decorative concrete flooring an excellent choice for any interior or exterior especially driveways and garage floors. Of course you don’t want to leave any spills on the surface for a long period of time.
