Concrete floor smooth finish specifications.

Conform to aci 301. Floors are classified based on the intended use of the floor see the table below that was adapted from aci 302 1 r 04 concrete floor and slab construction. When finish is not indicated provide smooth form finish as specified above. The arrangement of the facing material shall be orderly and symmetrical with the number of seams kept to the practical minimum.

The best degree of concrete floor flatness and levelness should be strived for since the floor finish may enhance imperfections such as high and low spots resulting from placement and finishing. Finishes shall be performed as called out on the drawings and in referenced specifications. Conform to aci 301. Each class includes what aci 302 calls special considerations and suggested finishing techniques.

The most prevalent texture or finish for internal exposed concrete floors is polished either power trowelled for a smooth solid appearance or diamond ground to expose the aggregates. The form facing material shall produce a smooth hard uniform texture on the concrete. A floor flatness rating of 40 5 and a floor levelness of 35 5 is required on newly placed concrete. Apply sandblasted finish to exposed concrete surfaces where indicated.

Scope according to grit sizes shown below.
