ULTRATECH GROUT CG is a single-component, polymer-modified, cement-based tile joint filling grout designed to provide durable, neat and uniform filling between tiles and stone surfaces. It is formulated with white cement, selected fillers and performance-enhancing additives to deliver strong adhesion, reduced water absorption and a smooth aesthetic finish. Unlike conventional grout mixes, it offers consistent quality, easier application and improved joint durability for both residential and commercial installations.

The product is intended for joint filling—not tile fixing and is suitable for ceramic tiles, vitrified tiles, marble, granite and natural stone installations. It performs effectively on both horizontal and vertical surfaces, making it suitable for floors as well as wall applications. Recommended joint size is up to 6 mm × 6 mm.

One of its major advantages is low shrinkage performance, helping maintain compact, crack-resistant joints after curing. The formulation also provides reduced water absorption, improving long-term durability and helping protect tile edges and underlying surfaces. Since it is a non-curing grout system, installation becomes faster and more convenient with less maintenance during application.

For application, surfaces should be clean and free from dust, oil, laitance or bond-breaking contaminants. The grout should be mixed with approximately 27–29% water by weight until a lump-free consistency is achieved and applied within the 1-hour pot life. Excess material should be cleaned after joints dry to obtain a neat appearance.
