Ultracolor Plus grout is a mortar made from a mixture of special hydraulic binders, selected aggregates, special polymers, waterproof additives, organic molecules, and pigments. Ultracolor technology is based on a special, self-hydrating hydraulic binder that ensures perfect color uniformity through two innovative technologies developed by MAPEI: BioBlock® and DropEffect®.

BioBlock® technology involves special organic molecules distributed to form a highly effective, anti-alkaline, fast-hardening and drying polymer mortar with DropEffect® waterproof technology and mold resistance. It is designed for joints with a thickness from 2 to 20 mm.
