Bostik and StarQuartz Industries have teamed up to roll out Bostik TruColor Pre-Mixed Grout for tile and stone applications. Available in 20 colors in Bostik’s Hydroment and Durabond lines, the premixed grout provides “unmatched color accuracy and consistency as well as stain/chemical resistance,” according to Bostik. The product also offers “green” benefits, the company adds.
