Custom Building Products has expanded the color palette of its Prism SureColor Grout line with the addition of 10 new colors. These new hues - Fawn, Summer Wheat, Sandstone, Tobacco Brown, New Taupe, Light Smoke, Charcoal and three grays - bring the number of color choices to 22. Prism SureColor Grout features the proprietary CustomLite Technology, which uses a cellular aggregate composed of 100 percent recycled material in lieu of the typical sand. This technology makes the grout up to 30 percent lighter than traditional grouts, Custom Building says.
