Sandstone Grey Rect wall or floor tile 29x59cm by Azulev.

Sandstone is the reinterpretation of quartzite stone. Its soft press relief, along with a graphic design that enhances its texture, imbues the piece with realism and naturalness. In rectified porcelain, Sandstone, for its technical performance is an excellent indoor and outdoor option. It comes in several formats so it is a stone that can be carried on both wall and the floor.

A glazed porcelain tile with a textured matt finish. As a digitally printed stone-effect tile, the Sandstone Grey imitates real stone without the inherent variation found in natural products. Large format tiles such as this can create an illusion of space in smaller rooms because of fewer grout lines.

As a rectified tile, the Sandstone Grey is a tile which has been mechanically cut to an exact size. Tiles that are not rectified can have very slight variations in size so rectification produces exact facial dimensions with more precise and narrow grout lines when tiling.

Frost-proof tiles are an important consideration for rooms where the temperature may drop below zero such as utility rooms and conservatories. Tiles with a frost-proof glaze have a water absorption rate of less than 0.5% meaning they are ideal for such conditions. Tiles which are not frost-proof may absorb water which would freeze at zero and below, causing the tile to crack.
