Description from Claybrook

Product Information
These kit-kat style terracotta mosaics are the largest of the five available, ideal for walls or floors and even suitable for wetter areas like showers when sealed correctly, unusual for natural clays similar to these. Use as a kitchen splashback as a distinctive feature.
Made from a unique Italian clay called Galestro. This clay is only found near Florence, in the valleys off the Ema and Greve rivers.
A distinctive coloured terracotta. These mosaics feature a brushed surface and tumbled edge, creating a beautifully varied surface texture.
Samples are not sealed.
Requires the surface salts removing, before being sealed. The recommended products are Ema Easy Remover and Ema Easy Sealer. In some cases the additonal application of Ema Easy Wax, further protects the floor and makes it easier to clean. Please refer to the Claybrook Terracotta Installation Guide for guidance.
We strongly recommend an experienced Terracotta fitter is employed.
Tiles should be unpacked and dry laid prior to installation to ensure any natural variation, between sheets is evenly distributed across the floor or wall.
If you are not using the Ardex FL grout that we recommend and sell, please test your chosen grout on the tile surface before installing.
