Frontier20 Montauk Black Mix + Slate Look Porcelain Pavers 24x48

This is the Frontier20 Montauk Black Mix +, in a slate face. Frontier20 is the 20 mm outdoor programme, thick enough to be laid dry on gravel, sand or pedestals.

Slate is split rather than sawn, so its face has a shallow cleft texture, and that texture is pressed into this tile. Mesh backing holds the layout, which is what makes a mosaic practical on a shower floor or a backsplash.

The body is 20 mm and the edges are rectified, so it lays with a tight grout joint. The surface is matte. One box covers 7.75 sq ft, 1 piece.

It is made in the United States, at Landmark's Mount Pleasant plant in Tennessee.
