	CONCRETE COATINGS
	** NOTE TO SPECIFIER ** Kemiko Concrete Stains; Concrete Coatings. . This section is based on the products of Kemiko Concrete Stains, which is located at: PO Box 1109 Leonard, Texas 75452 Tel: (903) 587-3708 Fax: (903) 587-9038 E-Mail: sales@kemiko.com Web: www.kemiko.com . Kemiko Stone Tone Stain transforms an ordinary concrete slab into a luxurious floor that resembles marble or glazed stone. When concrete is stained and scored Kemiko creates the appearance of expensive flooring at a fraction of the cost. Unlike paint, Kemiko Stone Tone Stain reacts with the minerals present in the concrete giving it the look and feel of natural stone. Each concrete slab accepts the stain in varying degrees of intensity creating stunning, multi-hued color variations and an uneven surface that looks perfectly aged..Kemiko Stone Tone Wax or Sealer can be applied to further enhance depth of color and provide surface protection. We look forward to assisting you or your client in creating beautiful, durable, and affordable stained concrete projects.
