Buddy Rhodes Signature Color Series is a series of ultrafine concrete pigments that are used integrally in concrete mixes in order to produce a wide color range. The standard color range is based on one pound (bag) of pigment per bag of any of the blended mixes, but you can double that dosage for richer colors, reduce the amount of pigment for lighter tones, or blend the colors for various hues. The pigment is also used in conjunction with the Bone Paste Plus paste for filling voids in your finished concrete piece.
