Mapei Fast-Setting Grout, 5Kg, Used for Interior and Exterior Ceramic and Stone Joints, Medium Grey - Pack of 4

It is formulated for joint widths from 1 mm (1/32 inch) up to 20 mm (3/4 inch).

It can be used on walls and floors for all types of ceramic tiles, porcelain stoneware, marble, and other natural stones. It is suitable for both interior and exterior applications.

Key features include a very fine composition for excellent workability, advanced protection against mould and bacteria, and an anti-stain system. It offers an extended open time, Polycolbond technology to limit staining and ease cleaning, and strong colour consistency with a thixotropic formulation for easy application and finishing. It also provides high water resistance and chemical/atmospheric resistance, with a 15-color range.

Ultracolor Plus 112 is part of a 15-color range, with Medium Grey (112) being one of the available colors. The product line emphasizes color consistency across batches.

Mix the grout with clean water to a smooth, lump-free paste using a low-speed mixer. Add powder gradually and mix until the desired consistency is reached. After mixing, apply the grout with a rubber float, pressing it firmly into the joints. Allow the grout to set for a short period, then remove excess grout with the damp sponge while the joints are still workable. The thixotropic formula helps it spread and finish cleanly.

Wipe the surface with a damp sponge to remove grout haze while the grout is still fresh. Avoid over-wetting to prevent staining. If haze persists after initial setting, perform a second damp-cleaning pass. For best appearance, follow up with a neutral cleaner after the grout has fully cured.

Wear appropriate PPE such as gloves and eye protection when handling cementitious products. Avoid generating or inhaling dust, wash skin after handling, and keep the product in a cool, dry place. Follow local disposal guidelines for packaging and unused material.

Keracolor S is another cementitious grout option in Mapei’s range. Ultracolor Plus 112 emphasizes anti-stain technology, extended open time, and mould resistance, making it a strong choice where stain resistance and ease of cleaning are priorities. Keracolor S is a solid, traditional cementitious grout option; the choice depends on whether you value stain resistance and extended open time (Ultracolor Plus 112) or a standard cementitious grout (Keracolor S).

Ultracolor Plus FA is another variant in the Ultracolor family, designed for similar tile grouting needs with potential differences in finish, flexibility, or water resistance. Ultracolor Plus 112 focuses on the 1–20 mm joint range and a wide color range with anti-stain properties, while FA variants may target specific performance aspects or application conditions. Check the specific FA formulation to determine the best fit for your project.

Yes, Ultracolor Plus 112 is intended for interior and exterior applications and is formulated to provide strong resistance to water, chemicals, and atmospheric agents, making it suitable for exterior and high-traffic areas in many tile installations.
