In general sandstone paving is not slippery if it is well maintained. There are a great deal of finishes available in this material, each with different natural slip resistances. The natural riven surface of hand split sandstone paving has the best slip resistance. This slip resistance reduces as the surface of the sandstone becomes smoother, such as honed or polished.
Different types of Indian sandstone and their slip resistance:
Riven – excellent slip resistance
Honed – average slip resistance
Polished – low slip resistance (Only possible on very hard, less porous stones).
