Do not apply cement grout other than that created by the rubbing <br />process. <br />2. Grout -Cleaned Finish: Wet concrete surfaces and apply grout of a consistency of thick <br />paint to coat surfaces and fill small holes. Mix one part portland cement to one and one- <br />half parts fine sand with a 1:1 mixture of bonding admixture and water. Add white <br />portland cement in amounts determined by trial patches so color of dry grout will match <br />adjacent surfaces. Scrub grout into voids and remove excess grout. When grout <br />whitens, rub surface with clean burlap and keep surface damp by fog spray for at least 36 <br />hours. <br />D. Related Unformed Surfaces: At tops of walls, horizontal offsets, and similar unformed surfaces <br />adjacent to formed surfaces, strike off smooth and finish with a texture matching adjacent <br />formed surfaces. Continue final surface treatment of formed surfaces uniformly across adjacent <br />unformed surfaces unless otherwise indicated. <br />3.11 FINISHING FLOORS AND SLABS <br />A. General: Comply with ACI 302.1R recommendations for screeding, restraightening, and <br />finishing operations for concrete surfaces. Do not wet concrete surfaces. <br />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. <br />Repeat float passes and restraightening until surface is left with a uniform, smooth, granular <br />texture. <br />1. Apply float finish to surfaces to receive trowel finish and to be covered with fluid -applied <br />or sheet waterproofing, built-up or membrane roofing, or sand -bed terrazzo. <br />C. Trowel Finish: After applying float finish, apply first troweling and consolidate concrete by hand <br />or power -driven trowel. Continue troweling passes and restraighten until surface is free of <br />trowel marks and uniform in texture and appearance. Grind smooth any surface defects that <br />would telegraph through applied coatings or floor coverings. <br />1. Apply a trowel finish to surfaces exposed to view or to be covered with resilient flooring, <br />carpet, ceramic or quarry tile set over a cleavage membrane, paint, or another thin -film - <br />finish coating system. <br />2. Finish surfaces to the following tolerances, according to ASTM E 1155, for a randomly <br />trafficked floor surface: <br />a. Specified overall values of flatness, F(F) 25; and of levelness, F(L) 20; with <br />minimum local values of flatness, F(F) 17; and of levelness, F(L) 15. <br />b. Specified overall values of flatness, F(F) 35; and of levelness, F(L) 25; with <br />minimum local values of flatness, F(F) 24; and of levelness, F(L) 17; for slabs -on - <br />g rade. <br />c. Specified overall values of flatness, F(F) 30; and of levelness, F(L) 20; with <br />minimum local values of flatness, F(F) 24; and of levelness, F(L) 15; for suspended <br />slabs. <br />d. Specified overall values of flatness, F(F) 45; and of levelness, F(L) 35; with <br />minimum local values of flatness, F(F) 30; and of levelness, F(L) 24. <br />3. Finish and measure surface so gap at any point between concrete surface and an <br />unleveled, freestanding, 10 -ft.- long straightedge resting on two high spots and placed <br />anywhere on the surface does not exceed 1/8 inch. <br />CAST -IN-PLACE CONCRETE 033000-16 <br />
