C. CONCRETE FINISHING <br />1. After striking -off and consolidating concrete, smooth the surface by <br />screening and floating. Use hand methods only where mechanical <br />floating is not possible. Adjust the floating to compact the surface <br />and produce a uniform texture. <br />2. After floating, test surface for trueness with a 20 ft. straight edge. <br />Variations exceeding one-third inch for any two points within 10 feet <br />shall not be acceptable. Distribute concrete as required to remove <br />surface irregularities, and refloat repaired areas to provide a <br />continuous smooth finish. <br />3. Work edges of slabs, gutters, back top edge of curb, and formed <br />joints with an edging tool, and round 10-1120' radius, unless otherwise <br />indicated. Eliminate any tool marks on concrete surface. <br />4. After completion of floating and when excess moisture or surface <br />sheen has disappeared, broom finish sidewalks by drawing a fine - <br />hair broom across concrete surface, perpendicular to a line of <br />pedestrian traffic. <br />5. Do not remove forms for 24 hours after concrete has been placed. <br />After form removal, clean ends of joints and point -up any minor <br />honeycombed areas. <br />D.

If no joint sealer, place top of <br />joint filler flush with finished concrete surface. <br />(4) <br />Fumish joint fillers in one-piece lengths for the full <br />width being placed, wherever possible. Where more <br />than one length is required, lace or clip joint filler <br />sections together. Pieces shorter than four inches <br />shall not be used unless specifically shown as such. <br />(5) <br />Protect the top edge of the joint filler during concrete <br />placement with a metal cap or other temporary <br />material. Remove protection after concrete has been <br />placed on both sides of joint. <br />(6) <br />Fillers and Sealants: Comply with the requirements <br />of these specifications for preparation of joints, <br />materials installations and performance, and as <br />herein specified. <br />C.
