ShimmerStone® is not a regular tint base that can be tinted with a paint formula. We have created our own set of 15 Color Concentrates that can be used to create 90 pre-formulated hues. These colorants are highly concentrated and are 5 times stronger than universal colorants. They can be used to tint ShimmerStone, Venetian Plaster, primers, paints, and glazes as well. When tinting ShimmerStone do not exceed 4oz. of our Color Concentrates.
