Abstract
An improved surface seeded exposed aggregate concrete and method of use is disclosed characterized by use of small, rounded aggregate, preferably sand, being broadcast over the upper surface of the concrete. The broadcast aggregate is mixed into the cement paste derived from the concrete matrix by magnesium hand floats and finished by hand sponging. A surface retarder and vapor barrier is than applied to cover the concrete surface for approximately four to twenty four hours. Subsequently, any surface film is washed from the surface of the concrete and the concrete is cured by fogging or soaker hose. Approximately thirty days later, the surface residue is removed from the concrete with a stem/acid wash providing an exposed aggregate concrete having extreme flatness and high wear resistance suitable for high traffic areas and improved asthetics resembling stone, granite or marble.
