Mapei Ultracolor Plus London Grey – 5kg

Mapei Ultracolor Plus London Grey is listed as suitable for wall applications in bathrooms and kitchens, making it a practical choice for tiled shower walls, splashbacks, and feature walls. It incorporates BioBlock technology, which actively inhibits mould growth – a particularly important feature in humid bathroom environments. Its water-repellent surface also makes it easy to wipe clean, helping the grey tone stay looking fresh.

The product attributes for Mapei Ultracolor Plus London Grey list it as suitable for wall use, so we would recommend checking the Mapei data sheet or contacting us before using it on floor surfaces to ensure it meets the wear and slip-resistance requirements for your project. For a coordinated grey bathroom scheme, it pairs beautifully with wall tiles and you can explore our other Ultracolor Plus floor-rated grouts to match on the floor. Using the correct grout for each surface ensures lasting performance and keeps your installation warranty intact.

At the standard coverage rate, 1 kg covers approximately 1.33 m² with 100 mm x 100 mm x 8 mm tiles and 3 mm joints, so a 5 kg bag will cover around 6.65 m² at those dimensions – enough for a good-sized bathroom wall area. The anti-efflorescence formula in Mapei Ultracolor Plus London Grey is specifically designed to prevent white salt deposits from forming, which means the grey colour remains uniform and true across the entire tiled surface. Measure your wall area carefully and factor in any offcuts or wastage when calculating how many bags to order.
