Our solvent-based interior dye is formulated using extremely fine molecules of color designed to penetrate and color any cementitious surface. Interior concrete dye was created for use with polished concrete, but can be used as a base color or touch up for concrete that has received integral color, dry shake hardeners, acid stains or even as an overlay to itself. Solvent-based dye is perfect for concrete graphics or stenciling. Concrete can be polished to almost a mirror surface bringing out the vibrant color and depth possible with these colors.
