THE CITY OF SUNNY ISLES BEACH <br />PROJECT NO. 21-1011 <br />BUILDING DEPARTMENT RELOCATION TO ANNEX <br /> <br />Project No. 21-1011 November 2024 033100 Structure Concrete-12 <br />period. <br /> <br />E. Verify compatibility of floor treatment materials with mastics and finish <br />materials to be applied to floor. <br /> <br /> <br />F. Where floors are to be covered, apply one coat of dissipating curing <br />compound, applied immediately after finishing. <br /> <br />G. Where floors are not scheduled to be covered, apply two coats of curing and sealing <br />compound, with first coat applied immediately after finishing and second coat just <br />before final acceptance of building except where floor covering materials are to be <br />applied. <br /> <br />H. Apply a non-slip aggregate to stair treads and landings, and ramps not <br />scheduled to receive floor covering, in accordance with manufacturer's <br />instructions, trowel to a hard finish, and treat surface with liquid hardener <br />without sealer. <br /> <br />3.7 REPAIR OF VERTICAL SURFACE DEFECTS <br /> <br />A. Upon stripping of forms, vertical surfaces shall be inspected for defects caused by <br />surface air voids, honeycombing, form tie holes, peeling, and fins. <br /> <br />B. Surface air voids shall be repaired with a unit packaged mixture of sand and <br />cement mixed on job site with water and a unit of acrylic. Mixture shall be brushed <br />uniformly on to surface and into voids. Where surface is to be exposed, surface <br />finish of repair shall match adjacent surface. <br /> <br />C. Honeycombed and other defective concrete shall be removed down to sound <br />concrete and patched to match adjacent surfaces. <br /> <br />3.8 FINISHING OF FORMED SURFACES <br /> <br />A. After removal of forms and repair of defects, surfaces of concrete shall be given <br />finishes specified below. <br /> <br />B. When finish is to match a sample furnished to Contractor, sample finish shall be <br />reproduced on an area at least 100 square feet in size in an inconspicuous location <br />designated by Engineer/Architect prior to application in the specified area. Application <br />of finish shall not be made until approved by Engineer/Architect. <br /> <br />C. Rough Form Finish: Surface left with texture imparted by forms; form facing material <br />not specified; tie holes and defects shall be patched; fins exceeding 1/4-inch shall be <br />chipped or rubbed off. <br /> <br />D. Smooth Form Finish: Surface produced by form facing material shall be a smooth, <br />hard, uniform texture on concrete; forms may be plywood, tempered form grade <br />hardboard, metal, plastic, paper or other acceptable material capable of producing <br />finish; arrangement of facing material shall be orderly and symmetrical with number <br />of seams kept to practical minimum; forms supported to prevent deflection and to <br />maintain tolerances; tie holes and defects shall be patched; all fins shall be <br />removed.
