Mapei Fast-Setting Grout, 5Kg, Suitable for Durable, Water-Repellent Joints in Ceramic and Porcelain Tiles, Volcano Sand - Pack of 4

Key features include good adhesion and mechanical strength, stain resistance, suitability for tiles and natural stones, and aluminium pigmentation (Alu) to help resist discoloration. It is packaged as four 5 kg bags per box for convenient handling on larger projects.

Each box contains four bags of 5 kg each, giving you 20 kg of grout per box, which is practical for mid to large tiling jobs.

It is suitable for a wide range of ceramic tiles and natural stones, including terracotta, enamel, lava stone, travertine, clinker, micro mosaics, porcelain tiles, and other ceramic or natural stone applications within the 2–20 mm grout joint width range.

Mix the powder with clean water to achieve a smooth, lump-free consistency. Stir until a uniform putty-like texture is obtained, then allow it to rest briefly (slake) before applying to joints.

Use a rubber grout float to press the grout into the joints, ensuring joints are fully filled. After initial setting, wipe away excess grout with a damp sponge and continue cleaning to reveal the final color and texture.

Ultracolor Plus Alu is formulated to be stain resistant, and sealing is generally not required for typical interior use. Regular cleaning is usually sufficient to maintain its appearance.

Wear gloves and eye protection when handling the powder and during mixing. Work in a well-ventilated area, avoid inhaling dust, and keep out of reach of children. Wash hands after use and clean any residue from skin and eyes promptly.

Store the unopened bags in a dry, cool place away from moisture. Once opened, reseal the packaging to prevent moisture absorption and use within the project timeframe for best results.

It's well-suited for interior tiling projects such as bathrooms, kitchens, living areas, and splashbacks where ceramic tiles or natural stones are used, especially in areas with potential moisture exposure or heavy use.

Ultracolor Plus Alu emphasizes aluminium pigmentation for reduced discoloration and strong stain resistance, making it a reliable interior grout choice. Compared with other cementitious grouts on Fepy, Ultracolor Plus Alu tends to offer a balance of color stability and ease of maintenance for everyday installations.
