503 Gray Pigment is an epoxy-based liquid colorant used to tint the epoxy mixture gray, providing an even, gray color base for the final finish system.
Add to the mixed resin/hardener at a rate of approximately one teaspoon of pigment to 8 fl oz of epoxy.
More pigments will increase opaqueness and mixture viscosity.
One 4 fl oz bottle will tint approximately 1.5 gal of epoxy.
