Adding our exclusive Ocher and pigment colors to grout can greatly enhance the beauty of tile. Ratios should not exceed 10% to the weight of the grout. Oxides will produce the darkest colors and other pigments will produce pastel colors.
Because grout base is white, only pastel to medium shades can be achieved. The color can be slightly darkened by the use of sealants that change the light refraction.
Pre-colored mortar can have additional color added to pull it in a certain direction, however that ratio should not exceed 3%. The addition of extra bonding agents suitable for grout are recommended when adding pigment.
