Gemstone Pool Surfaces, Inc. is proud to announce our newest alliance with Mesa Masterbatch. In an effort to further our commitment to providing the highest level of product reliability to our customers, Mesa Masterbatch has created a technologically advanced color concentrate formula exclusively for the Gemstone ® line. The high quality, complex inorganic pigment formula is impervious to acid or alkali environments, and our formula helps make the finish hydrophobic. This helps prevent aggressive chemicals from getting into the mix and improves durability over time.
