MAPEI Ultracolor Plus FA is an ultra-premium grout featuring DropEffect technology, which significantly reduces water absorption and stain susceptibility. The FA stands for Fine Aggregate, which allows the grout to be utilized in joints ranging from 1/16-inch to 3/4-inch wide. By utilizing fine aggregate, it provides the strength needed for wide joints while remaining safe for use on delicate, scratch-prone surfaces like polished natural stone or glass tile. This is a fast-setting, polymer-modified formula that resists the efflorescence commonly found in standard cement-based grouts. Additionally, it includes BioBlock technology to inhibit the growth of mold and mildew within the grout line. Because it cures quickly—often allowing foot traffic in 3 to 4 hours—it is a preferred choice for residential and light commercial projects where downtime must be minimized. Note that while it is highly durable, it remains a cement-based product and requires proper maintenance to preserve its long-term aesthetic.
