Packaged in pre-measured repulpable bags for accurate and convenient coloring of concrete. 11 standard base colors provide 44 color options by varying the number of bags per cubic yard. The Select Grade Integral Color represents dosages ranging from 1 bag of a single base color for two cubic yards of concrete to three bags of a single base color for one cubic yard of concrete. By varying the bag dosage, each base color can produce 4 different colors. Do not open bags. Simply toss the dissolving bag(s) into the mixer. This eliminates the mess and inaccuracy associated with the handling of loose colorants. The color chart approximates the color of cured and sealed concrete designed with medium gray Portland cement. Local materials, finishing techniques, texture and method of curing and sealing will affect the final color.
