Is polished concrete slippery?

• 

Slip is very hard to describe and interpret, what someone may think is fine another person may find very slippery. Generally speaking the higher the gloss level and the flatter the surface the slipperier a floor will be especially when wet. In our opinion in dry conditions polished concrete performs just as well, if not better, than tiles of a similar gloss level. If you are concerned about slip in an area exposed to water (uncovered outdoor/pool area/ shower) either reducing the finishing level for polished concrete or adding grit to a coating system can assist in achieving better grip. The grind, etch and seal system has been designed specifically for areas requiring considerable grip and is suitable for outdoor areas exposed to weather.
