Is exposed aggregate slippery when wet?

No — quite the opposite. Exposed aggregate’s textured, stone-studded surface genuinely offers better slip resistance than plain, smooth concrete, both wet and dry, which is exactly why it’s such a popular choice for driveways, pool surrounds and pathways.

The texture comes from exposing the aggregate (stone) within the concrete mix at the surface, rather than leaving a smooth troweled finish — this creates real grip that smooth concrete doesn’t offer to the same degree.

Like any outdoor surface, exposed aggregate can still accumulate algae or grime over time if not properly maintained, which can reduce grip — periodic cleaning and appropriate sealing keeps it performing as intended.
