This section specifies finishing of concrete surfaces.

1.2 - Related Work Specified Elsewhere

02512 - Concrete Sidewalks 03100 – Concrete Formwork

1.3 - Locations

Provide Class 1 finishing to all concrete surfaces.

PART 2 - PRODUCTS

2.1 - Grout

Patching Grout - 1 part portland cement, 2 parts sand.

Finishing grout - equal parts portland cement and sand.

PART 3 - EXECUTION

3.1 - Class I, Ordinary Surface Finish

As soon as forms are stripped, remove to a minimum depth of 1/4 inch, any projecting wire or metal devices used in forming. Remove fins caused by form joints. Patch all holes, depressions, small rock pockets, and form tie cones by first saturating with water and packing stiff patching grout into voids.

Repair large holes, rock pockets, spalls, and honey combs by chipping away all coarse or broken material until a dense uniform surface of concrete remains; saturate with water, apply thin layer of neat cement; pack stiff patching grout, and thoroughly tamp.

Preshrink patching grout by mixing approximately 30 minutes before using.

Float patches with wooden float before initial setting; provide neat, well blended patch.

Cure patches for 12 hours by continuous wetting.

3.2 - Class 2, Rubbed Finish

After forms are stripped and all patching grout has set, start the rubbed finish as conditions permit. Rub with rubber or wood float to remove form marks and irregularities. If the float cannot produce a smooth uniform surface, grind the surface and provide a sack finish as follows:

Thoroughly wet surfaces immediately before work. Rub or grind with medium-coarse abrasive stone, Specifications P a g e | 26

using small quantity of mortar.

Continue until form marks, projections, and irregularities are removed and voids filled.

Apply finishing grout with brush or burlap, completely filling pits, to provide a uniform texture and color.

3.3 - Class 3, Float Finish

Immediately after placing concrete for horizontal surfaces, vibrate, tamp, and strike off with screed, or templates if crowns are required. Hand finish to smooth, even surface with wood float. After excess moisture has dissipated but concrete is still plastic, check for proper grades, crowns, and uniformity. Fill or cut down incorrect surfaces; refloat for final finish. Use no mortar for leveling.

3.4 - Class 4, Trowel Finish

Prepare surface as in a Class 3 Float Finish. When water sheen has left surface, steel trowel to a smooth surface, free of blemishes. Trowel to a final finish after concrete has hardened sufficiently to prevent drawing moisture and fine material to surface. Trowel to produce a dense, smooth, impervious surface, free of defects and blemishes. Do not use mortar or other materials to facilitate finishing concrete.

Tool exposed edges with a slightly rounded edging tool.

Tool joints with a groover.

3.5 - Class 5, Broomed Finish

Prepare surface as in a Class 4, Trowel Finish. Lightly broom to a roughened finish of uniform pattern and texture.

Tool exposed edges with slightly rounded edging tool.

Tool joints with a groover.
