Ultracolor Plus Max is an ultra premium, fast-setting, polymer-modified, nonshrinking grout that offers rich and vibrant colors with maximized color depth and color consistency. This fine-aggregate grout can be used for joint widths from 1/16" to 3/4" (1.5 mm to 19 mm). Ultracolor Plus Max includes DropEffect technology for reduced surface absorption, helping to repel water, dirt and grime from penetrating grout joints. It is also specially formulated with MAPEI’s High-Hydrated Cement Technology (HCT) to provide advantages over traditional grout, such as eliminating efflorescence and increasing stain resistance.
