Exposed Aggregate and Broom Finishes are products we have been providing our customers for 28 years. They are very popular with our customers.
An Exposed Aggregate finish is done by first ordering the right mix from the Concrete batch companies, after laying the concrete and sealing it up we let the concrete sit undisturbed for several hours until the concrete starts to set to the point where it is difficult to manipulate the surface. We than spray a retardant on the surface. This allows the body of the concrete to completely set up while the surface is still soft. At the proper time we wash the surface off using a garden hose and lots of water.
The final result is we have washed the sand and cement off the surface to create an Exposed Aggregate finish.
Broom Finish? There really is not a lot to say here. This product is everywhere from City Sidewalks to back yard Patios to Tennis Courts. A very popular low cost product used for many different types of applications.
