Vibrant, Chromatic colors are possible when using grout from Grout360. The material you will receive already has the color added and 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 have a tendency to absorb the pigment color from the grout. White tiles with matte surfaces or unglazed porcelain finishes are the ones we see that have the most staining issues. It is recommended that you seal porous and sometimes non-porous tile with a grout release/pre-sealer prior to applying the grout. Microscopic surface cracks and crazing 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 after testing, send us an email asking about the return options. Some stains can be removed by using a cleaning product called Goo Gone.
