Mechanically abrade concrete surfaces by method of shot blasting to a uniform profile in accordance with ASTM D 4259 and meeting ICRI Surface Profile CSP 3. Do not acid etch. Clean prepared surfaces in accordance with ASTM D 4258. Protect adjacent finished surfaces by masking. Mask termination on vertical surfaces. Protect weep holes and drains. TERMINATIONS AND PENETRATIONS Prepare vertical and horizontal surfaces at horizontal to vertical transitions, terminations, joints, and penetrations through traffic coatings in accordance with ASTM C 1127 and manufacturer's written instructions, using accessory materials specified. At terminations of traffic coating exposed to traffic, rout 1/4 by 1/4 inch keyway in concrete. Detail Preparation: Prepare non-moving shrinkage cracks, large cracks, construction joints, expansion joints, projections and protrusions, penetrations, drains, and changes in plane in accordance with manufacturer's written instructions and details, . Prepare joints and cracks in substrate in accordance with ASTM C 1127 and ASTM D 4258 and manufacturer's written instructions. Coating Installation: Comply with manufacturer's written instructions. Allow joint coatings to cure adequately before coating with traffic coating. Provide coating cants at penetrations and at horizontal-to-vertical intersections. Tool coating material to form 45 degree angle transition. Penetrations must be grouted solid at all instances. Rout and fill cracks with coating and tool flush with surface. Feather edges of joint coating applications. Allow coating to cure. Fill expansion joints with backer rod and joint sealant contact Tremco for sealant recommendation. Do not apply traffic coating over expansion joints. DECORATIVE QUARTZ TRAFFIC-COATING APPLICATION Primer: Prime surfaces to receive traffic coating system. Allow to cure before proceeding. traffic-coating application in presence of manufacturer's technical representative. Apply traffic coating according to manufacturer's written instructions. Verify that wet film thickness of each coat complies with requirements every [100 sq. ft. (9 sq. m)]. Apply number of coats of specified compositions for pedestrian coating at locations indicated on Drawings, per manufactures written installation instructions traffic coatings to prepared wall terminations and vertical surfaces to height indicated; omit aggregate on vertical surfaces. Cure traffic coatings. Prevent contamination and damage during application and curing stages.
