You just wash away the thin layer of surface mortar covering the aggregate by spraying with water and scrubbing with a broom until the aggregate is exposed to the desired depth. The timing of the operation is critical, however, so this method is often better suited for small jobs.
How to Do Exposed Aggregate Finish?
Exposed aggregate finish is a decorative type of concrete finishing that gives a unique, textured look to concrete surfaces.
This finish is achieved by exposing the aggregate, or small stones and pebbles, embedded in the concrete. This process is ideal for driveways, patios, sidewalks, and other outdoor surfaces.
With the right tools and materials, it is possible to achieve a beautiful exposed aggregate finish. The first step to creating an exposed aggregate finish is to prepare the surface.
Before starting the project, remove any debris from the area and clean the surface. Then use a pressure washer to remove any dirt or residue from the surface. Once the surface is clean and dry, the next step is to mix the concrete.
Depending on the type of mixer you have, you may need to mix the concrete in batches or all at once. If you are using a wheelbarrow, it is best to mix the concrete in small batches.
Once the concrete is fully mixed, it is time to pour the concrete onto the surface. Once the concrete is poured, it is time to add the aggregate.
Depending on the desired look, you can use a variety of materials, including pebbles, stones, or glass beads. Spread the aggregate evenly
