Vibrant, Chromatic colors are possible when using this grout. The material you will receive already has the color added and all you add is water.
Test for Staining, Very important: GROUT360 uses very strong pigments to achieve some colors, and these pigments may stain your tile. Some tiling materials like matte finish white tiles have a tendency to absorb the pigment color from the grout. It is recommended that you seal porous and sometimes non-porous tile with a pre-sealer prior to applying the grout. Microscopic surface cracks and pores in the tile may allow the grout color to stain the tile. Testing a small area prior to use will determine if you need to pre-seal your tiles. If your tile does stain, send us an email asking about the return options.
Color variations can occur in any Portland cement product. Slight color differences are normal.
