  • Things To Remember When Using Exposed Aggregate Concrete ...

    If you are looking for a subtle effect, you could change the concrete mixture to provide a smoother finish by using finer sand or aggregate. However, if you want to create extra grip for a particular space, or even a bold effect on the surface of the concrete, you could add a slightly larger size of aggregate to the mix.

  • Exposed Aggregate Concrete - Decorative Pebble Finish ...

    An exposed-aggregate surface is obtained by placing concrete and then removing the outer 'skin' of cement paste to uncover decorative coarse aggregate (either batched into the concrete mix or seeded onto the surface). Because of its durability and skid resistance, an exposed aggregate finish is ideal for most flatwork including: Sidewalks.
