Frontier20 Sand Riser Limestone Look Porcelain Moldings 12x48

Frontier20 Sand, 12x48, a porcelain Riser with a limestone face. Frontier20 is the 20 mm outdoor programme, thick enough to be laid dry on gravel, sand or pedestals.

Real limestone is porous enough to stain and needs sealing on install; the porcelain version skips both. This is the upright face of a step, sized to sit under the tread and finish the flight.

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 2.58 sq ft, 1 piece.

Production is domestic, from the Mount Pleasant, Tennessee plant.
