Lythic Solutions has the new Duet Colors that are combined with Lythic Densifier. Duet Colors are water-based dyes that are specially formulated to be mixed into Lythic Densifier for deeper penetration and more effective bonding. The densifier becomes a permanent part of the concrete, and bonds the color right into it. Duet Colors are non-flammable, eliminating the hazards of solvent-based dyes. They are also free of solvent odors, minimizing interruption of normal activities. Dyes are available in 25 colors that enhance and showcase the natural character of the concrete.
