Patent ID: 8246269

Claim:
A method of producing surface seeded exposed particulate concrete utilizing a material spraying device to enable spraying of particulate at distances greater than ten feet from a sprayer, the concrete generally covering a large surface area greater than 10′×10′ and having a generally flat exposed particulate surface suitable for flooring applications, the method comprising: a) providing particulate having a mean diameter size of about ⅜″; b) preparing a subgrade to a desired grade; c) pouring a concrete mixture over the subgrade, the concrete mixture defining a generally horizontal upper surface; d) while a finger impression can still be made in the upper surface of the concrete mixture and the material spraying device is remote from the upper surface to be sprayed, continuously spraying the quantity of particulate with the material spraying device through air upon the upper surface of concrete mixture until the large surface area greater than 10′×10′ is covered with particulate; e) distributing the provided particulate upon the upper surface of the concrete mixture with the material spraying device wherein a level of uniformity of the distributed particulate is greater for the material spray gun than by shovel when particulate is distributed over the wide surface area greater than 10′×10′.
