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

Ultracolor Plus is suitable for ceramic, porcelain, and natural stone tiles with joint widths ranging from 2 mm to 20 mm. It can be installed both indoors and outdoors and is approved for use in pool and wet-area applications.

To mix, add powder to a clean container of water and stir until you get a smooth, lump-free paste. Allow the mix to slake briefly, then remix to a consistent texture. Use a rubber float to force the grout into joints at a 45-degree angle, remove excess grout with the float, and then wipe away haze with a damp sponge after the initial set. Follow the included grout guide for project-specific steps and cure guidelines.

Ultracolor Plus offers 20 standard colours, including Cerulean. You can adjust shade by varying the water amount during mixing to achieve custom hues, but always test a small area first to ensure color accuracy and consistency across batches.

The product is packaged as four 5 kg aluminium bags, totaling 20 kg. This packaging is convenient for large tiling projects and easier handling on-site.

Ideal for interior and exterior tiling projects, including bathrooms, kitchens, living areas, and walkways. It is also suitable for pools and other wet areas where a durable, stain-resistant grout is needed.

Once cured, the grout finish is designed to be easy to clean. Use mild cleaners and avoid highly acidic products. Regular cleaning and prompt removal of any water spots or stains will help maintain the seamless look. The grout guide provides maintenance tips specific to the product.

Ultracolor Plus has an odourless formula, which helps installation in enclosed spaces. As with any cementitious grout, wear appropriate protective gear (gloves and eye protection) and ensure good ventilation during mixing and application. Follow the product’s safety data sheet for full handling instructions.

Common issues include grout haze (wipe away with a damp sponge while the grout is still workable), efflorescence (flush with clean water and monitor moisture), and color variation between batches. If color consistency is critical, test a small area first and use the grout guide to align application techniques. Always follow standard cleaning and curing practices outlined in the grout guide.

Ultracolor Plus FA is a variant designed for faster setting and project turnaround, while Ultracolor Plus provides the standard cure and finish with a broad 2–20 mm joint range. Both share the same cementitious base and color range, but FA is optimized for quicker installs.

Keracolor S is a cementitious grout typically used for interior applications and smaller joints (often 1–8 mm). Ultracolor Plus is better suited for larger joint widths up to 20 mm and for outdoor/pool areas. See Keracolor S here: https://www.fepy.com/product/mapei-keracolor-s-5kg

Choose Ultracolor Plus for its 2–20 mm joint range, suitability for indoor/outdoor and pool/wet areas, a broad color palette (20 colours) including Cerulean, the odourless formulation for easier installation, and the included grout guide. The packaging (20 kg total) and easy water-only mixing add value for professional tiling projects.
