Does anyone have any experience with TEC Incolor Advanced Performance grout? I cannot find any reviews on this product. It appears to be similar to Fusion Pro and Mapei Flexcolor CQ; I can find tons of reviews on those products. Mapei appears to get the best reviews but my client insistent on a specific color from TEC Incolor. Is this a good grout? We are buying from a reputable flooring company. Thoughts? Thank you.
