Mapei Ultracolor Plus Manhattan Grey 5kg

Yes, Mapei Ultracolor Plus Manhattan Grey is specifically suited for use with porcelain tiles and is listed as suitable for both floor and wall applications, making it one of the most versatile options in the Ultracolor Plus range. The Manhattan Grey shade works particularly well alongside mid-tone and cool-toned porcelain tiles, providing a neat, contemporary finish. It is also compatible with underfloor heating systems, so it is a reliable choice for porcelain-tiled floors with UFH.

Mapei Ultracolor Plus Manhattan Grey has a pot life of 20-25 minutes once mixed, so it is best to mix only as much as you can use in that window to avoid waste. You should wait 15-30 minutes after application before finishing and cleaning the joints. Light foot traffic is possible in approximately 3 hours, which means tiled floors can be carefully accessed on the same day in most cases.

Based on the stated coverage of 1kg per 1.33m² for 100mm x 100mm x 8mm tiles with 3mm joints, you would need approximately 7.5kg to grout a 10m² floor at that tile size – meaning this 5kg bag would not quite be sufficient on its own for that area. However, coverage increases significantly with larger porcelain tiles, as bigger tiles mean fewer and shorter joint lines. We recommend calculating your exact joint dimensions or using Mapei’s coverage guidelines for your specific tile size to determine how many bags you need.
