C2 Seal™ is a patented copolymer formulation that not only seals concrete with a rich, high glossy finish but also provides the toughness of the C2 Hard™ product, our advanced hardener and densifier for horizontal concrete. This easy to apply lithium silicate treatment penetrates and reacts with concrete, increasing hardness, denseness and durability on old and new surfaces. This copolymer formulation improves damage from water, chemical attack and abrasion. C2 Seal™ is perfect for application on standard or decorative concrete and cementitious terrazzo. It protects and enhances the color intensity of integrally colored and color stained concrete, maximizes light reflectance and eliminates the need for floor waxes, liquid polishes and conventional resin based coatings. Safer than conventional sodium or potassium silicate hardeners, C2 Seal™ will not activate or contribute to surface ASR.
