Scratch Finish: While still plastic, texture concrete surface that has been screeded and bull - floated or <br />darbied. Use stiff brushes, brooms, or rakes. <br />1. Apply scratch finish to surfaces indicated and to surfaces to receive concrete floor topping and <br />other bonded cementitious floor finishes. <br />C. Float Finish: Consolidate surface with power- driven floats or by hand floating if area is small or <br />inaccessible to power driven floats. Restraighten, cut down high spots, and fill low spots. Repeat <br />float passes and restraightening until surface is left with a uniform, smooth, granular texture. <br />1. Apply float finish to surfaces indicated, to surfaces to receive trowel finish, and to floor and slab <br />surfaces to be covered with fluid - applied or sheet waterproofing, built -up or membrane roofing, <br />or sand -bed terrazzo. <br />D. Trowel Finish: After applying float finish, apply first trowel finish and consolidate concrete by hand <br />or power - driven trowel. Continue troweling passes and restraighten until surface is free of trowel <br />marks and uniform in texture and appearance. Grind smooth any surface defects that would <br />telegraph through applied coatings or floor coverings. <br />1. Apply a trowel fmish to surfaces indicated and to floor and slab surfaces exposed to view or to <br />be covered with resilient flooring, carpet, ceramic or quarry tile set over a cleavage membrane, <br />paint, or another thin film- finish coating system <br />2. Finish surfaces to the following tolerances, according to ASTM E 1155 (ASTM E I I55M), for <br />a randomly trafficked floor surface: <br />a. Plant Floor Slab on Grade: Specified overall values of flatness, F(F) 35; and of levelness, <br />F(L) 25; with minimum local values of flatness, F(F) 24; and of levelness, F(L) 17. <br />E. Broom Finish: Apply a broom finish to exterior concrete platforms, steps, and ramps, and elsewhere <br />as indicated. <br />1. Immediately after float finishing, slightly roughen trafficked surface by brooming with fiber - <br />bristle broom perpendicular to main traffic route. Coordinate required final finish with <br />Architect before application. <br />F. Trowel and Fine -Broom Finish: Apply a partial trowel finish, stopping after second troweling, to <br />surfaces indicated, to surfaces to receive resinous flooring, and to surfaces where ceramic or quarry <br />tile is to be installed by either thickset or thin -set method. Immediately after second troweling, and <br />when concrete is still plastic, slightly scarify surface with a fine broom. <br />3.10 MISCELLANEOUS CONCRETE ITEMS <br />A. Filling In: Fill in holes and openings left in concrete structures, unless otherwise indicated, after <br />work of other trades is in place. Mix, place, and cure concrete, as specified, to blend with in -place <br />construction. Provide other miscellaneous concrete filling indicated or required to complete Work. <br />B. Curbs: Provide monolithic finish to interior curbs by stripping forms while concrete is still green and <br />by steel - troweling surfaces to a hard, dense finish with corners, intersections, and terminations <br />slightly rounded. <br />CAST -IN-PLACE CONCRETE 033000- 13 <br />
