'Rock salt' texture is a weathered decorative finish to concrete slabs. Coarse rock salt is pressed into the concrete surface after finishing and is then washed away once the concrete has hardened. The finish may be used to replicate the subtle weathering effects on rocks exposed to the elements. A rock salt finish can be applied to either plain grey or colored concrete. Colored concrete should be integrally colored to ensure consistency of color through the textured surface. The rock salt process can be used in combination with a range of other finishes including the swirl float, swirl trowel or broomed finish.
