Recommended for

Granite, marble, limestone, travertine, slate, bluestone, flagstone, sandstone, concrete, brick masonry and other porous natural stone and masonry surfaces.

Common applications

Ideal for countertops, backsplashes, floors, walls, kitchens, bathrooms and other residential or commercial stone installations where strong stain protection is required without changing the natural finish.

Coverage

Up to approximately 900 sq. ft. per gallon for a single coat, depending on the porosity and condition of the surface.

Important: Antimicrobial product protection is designed to protect the treated surface and is not a substitute for normal cleaning practices. Always test in a small, inconspicuous area before full application and follow the manufacturer’s preparation and application instructions.
