CUALI® has collected the most popular and commonly used tile colors in the market and integrated them into 120 colors, can achieve the effect of “tile and seam in the same color” for most of tile. For the professional Tile Grout worker, this is a more efficient and personalized solution. We have creatively made a base material specifically for color modulation, and then made 7 color component A for the modulation. In practice, put these different color component A into base material at different ratio, then we can modulate any color.
