Epoxy based liquid colorants used to tint the epoxy mixture to provide an even color base for the final finish system. The colored surfaces also tend to highlight flaws and imperfections. Add to the mixed resin/hardener at a rate of approximately one teaspoon of pigment to 8 fl. oz. of epoxy. One 4 fl. oz. bottle will tint approximately 1-1/2 gal. of epoxy. Pigmented epoxy will degrade under sunlight-not intended as an exterior finish.
