Product Overview
Customs Prism Lightweight Grout
A lightweight, polymer-modified, cement-based grout that offers consistent color without mottling or shading, regardless of tile type, temperature or humidity. With dense joints that provide more stain resistance than standard cement grouts, cures quickly and develops high early-strength to accommodate grout joints from 1/16" (1.6 mm) to 1/2" (13 mm). Prism may be used for interior or exterior installations, including floors, countertops, walls, ceilings, showers, fountains and pools.
