Concrete Floor Smooth Finish Specifications

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.
Concrete floor smooth finish specifications. 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. The form facing material shall produce a smooth hard uniform texture on the concrete. Conform to aci 301. Conform to aci 301.
Apply sandblasted finish to exposed concrete surfaces where indicated. Concrete concrete floor finishing standard engineering specification issued and types of finish nov 1966 sb 10 u this page revised nov 1983 standard nov 1983 page 1 of 4 reaffirmed 1. 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. A floor flatness rating of 40 5 and a floor levelness of 35 5 is required on newly placed concrete.
A requirement for greater slip resistance is often a driver to explore other options such as the inclusion of retardants or shot blasting. Larger grit sizes are. Blasting operations and requirements. Scope according to grit sizes shown below.
Finishes shall be performed as called out on the drawings and in referenced specifications.
