Protected with MoldGard Technology, it actively resists mold and mildew growth in wet areas. This product is sold by the quart and weighs approximately 3.41 pounds. It is typically installed by tile setters, flooring contractors, or experienced DIYers working on residential tile projects.

PMG381QT is designed for interior use on new tile grout installation and restoration of existing grout joints. It is suitable for use in wet areas including tub surrounds, shower floors, and shower walls. It works on ceramic, mosaic, quarry, porcelain, stone tile, marble, and granite surfaces. This product is not suitable for steam rooms, areas with prolonged water exposure, or submerged applications. When working with porous stone, review the manufacturer surface preparation instructions before application, as porous surfaces may absorb grout and stain.
