Polished surface (terrazzo)
Polished surface is obtained by treating concrete surface with diamond grinding disks of different coarsenesses. The depth of the finishing is 1.5-5 mm and, if needed, the surface may also be polished as the final finish. Due to different and colourful aggregates, this surface is also called mosaic concrete or terrazzo. This is an exclusive method used for finishing external wall elements or stairs, half-paces and concrete floors.
