Method of forming surface seeded particulate

A method of producing surface seeded exposed particulate concrete having a generally flat exposed particulate surface suitable for flooring applications, the method comprising:

• a) preparing a subgrade to a desired grade;
• b) pouring a concrete mixture over the subgrade;
• c) screeding the concrete mixture to a desired grade and forming a top surface thereof;
• d) finishing the top surface of the concrete mixture with a float to seal the top surface and disposing a quantity of cement/fines derived from the concrete mixture at the top surface of the concrete mixture to form an upper surface of cement/fines concrete paste;
• e) spraying a quantity of particulate upon the upper surface of cement/fines concrete paste;
• f) mixing the quantity of particulate into the cement/fines concrete paste with a float to form an exposed surface of a depth of a mixture of surface-concentrated particulate and cement/fines concrete paste;
• g) applying a surface retarder uniformly over the exposed surface of the surface-concentrated particulate and cement/fines concrete paste;
• h) washing surface films from the exposed surface;
• i) curing the concrete mixture and paste to form a cured mixture and a cured paste;
• and
• j) washing the exposed surface to remove surface residue therefrom.
