Ash Grove KolorStone Kolorflex Admixture is an acrylic polymer emulsion specifically designed to be mixed with KolorStone concrete coatings when applying the Ash Grove KolorStone system. Using this admixture creates a tenacious bond with the substrate to be coated and aids in obtaining water and crack resistance and high flexural strength. It also creates a greater resistance to freeze-thaw lifting and spalling.
