Bomanite Color Hardener

Bomanite Color Hardener is a dry-shake material for coloring and hardening concrete flatwork, and is specially formulated for use in the installation of Bomanite and Bomacron cast-in-place colored, textured and imprinted concrete paving and flooring. Bomanite Color Hardener is a blend of three principal ingredients: mineral oxide pigments, cement and graded silica aggregates. Special conditioning admixtures are also included to improve workability. Bomanite Color Hardener is used in residential, commercial and municipal applications. Two grades of Color Hardener are available:

Regular Grade: This grade is recommended for all applications except areas subject to exceptionally heavy pedestrian traffic or heavy road traffic in freeze areas. Appropriate areas include residential driveways, patios, pool decks, entryways, walkways, showroom floors, lobbies and medians.

Heavy Duty Grade: This grade includes specially graded Emery (aluminum oxide) to increase wear resistance. It is normally recommended for installations that are expected to receive exceptionally heavy wear, including vehicular entrances, theme parks, plazas, crosswalks, street sections and high-traffic sidewalks.

Bomanite Color Hardener is the most effective coloring method to achieve your desired results in the installation of Bomanite and Bomacron. This method can also be utilized for other specified colored concrete applications including salt finishes, broom finishes and rotary finishes. A greater variety and intensity of colors are available by using this coloring method. Color hardener can be formulated to create a wide variety of hues from soft pastels to vivid blues and purples, which is difficult to achieve with other coloring methods. Bomanite Color Hardener also improves imprinting, while providing increased durability, wear resistance and fade resistance. Bomanite Color Hardener is applied by specially licensed, trained and equipped Bomanite licensees.
