Exterior Kolour Dye is a semi transparent dye formulated using very fine pigments designed to penetrate and color exterior and interior cementitious surfaces. Exterior Kolour Dye creates a unique, multi colored patina like effect that unlike paints, will not crack, chip, or peel. Exterior Kolour Dye is available in 28 standard colors but can be combined to create an unlimited color palate. When used properly it can create a mottling or marbleized effect very similar to acid stains.
