BEARDSLEY DESIGN ASSOCIATES CORNELL – NCP ANTI-STATIC RESILIENT TILE FLOORING STANDARD SPECIFICATIONS 09 65 37 - PAGE 4 OF 7 MARCH 29, 2013 PART 3 EXECUTION 3.1 EXAMINATION A. Examine substrates, with Installer present, for compliance with requirements for maximum moisture content and other conditions affecting performance of the Work. B. Verify that finishes of substrates comply with tolerances and other requirements specified in other Sections and that substrates are free of cracks, ridges, depressions, scale, and foreign deposits that might interfere with adhesion of floor tile. C. Proceed with installation only after unsatisfactory conditions have been corrected. 3.2 PREPARATION A. Prepare substrates according to manufacturer's written instructions to ensure adhesion of resilient products. B. Concrete Substrates: Prepare according to ASTM F 710. 1. Verify that substrates are dry and free of curing compounds, sealers, and hardeners. 2. Remove substrate coatings and other substances that are incompatible with adhesives and that contain soap, wax, oil, or silicone, using mechanical methods recommended by manufacturer. Do not use solvents. 3. Alkalinity and Adhesion Testing: Perform tests recommended by manufacturer. Proceed with installation only after substrates pass testing. C. Fill cracks, holes, and depressions in substrates with trowelable leveling and patching compound and remove bumps and ridges to produce a uniform and smooth substrate. D. Do not install floor tiles until they are same temperature as space where they are to be installed. 1. Move resilient products and installation materials into spaces where they will be installed at least 48 hours in advance of installation. E. Sweep and vacuum clean substrates to be covered by resilient products immediately before installation. BEARDSLEY DESIGN ASSOCIATES CORNELL – NCP ANTI-STATIC RESILIENT TILE FLOORING STANDARD SPECIFICATIONS 09 65 37 - PAGE 5 OF 7 MARCH 29, 2013 3.3 FLOOR TILE INSTALLATION A. Install static-control resilient flooring according to manufacturer’s written instructions B. Embed grounding strips in static-control adhesive. Extend grounding strips beyond perimeter of static-control resilient floor-covering surfaces to ground connections. C. Scribe, cut, and fit static-control resilient flooring to butt neatly and tightly to vertical surfaces and permanent fixtures including built-in furniture, cabinets, pipes, outlets, and door frames. D. Install static-control resilient flooring on covers for telephone and electrical ducts, and similar items in installation areas. Maintain overall continuity of color and pattern with pieces of static-control resilient flooring installed on covers. Tightly adhere static-control resilient flooring edges to substrates that abut covers and to cover perimeters. E. Adhere static-control resilient flooring to substrates using a full spread of static-control adhesive applied to substrate to produce a completed installation without open cracks, voids, raising and puckering at joints, telegraphing of adhesive spreader marks, and other surface imperfections. 3.4 CLEANING AND PROTECTION A. Comply with manufacturer's written instructions for cleaning and protection of floor tile. B. Perform the following operations immediately after completing floor tile installation: 1. Remove adhesive and other blemishes from exposed surfaces. 2. Sweep and vacuum surfaces thoroughly. 3. Damp-mop surfaces to remove marks and soil. C. Protect floor tile products from mars, marks, indentations, and other damage from construction operations and placement of equipment and fixtures during remainder of construction period. D. Cover floor tile with Ram Board Protective Card Board secured by painters tape and one layer of hard board or equal - until substantial completion by Div 23 and Division 27 Contractors. E. After substantial completion by Division 27 Contractor, but prior to final project closeout. If recommended in writing by manufacturer, apply protective static-control floor polish formulated to maintain or enhance floor covering's electrical properties; ensure static-control resilient flooring BEARDSLEY DESIGN ASSOCIATES CORNELL – NCP ANTI-STATIC RESILIENT TILE FLOORING STANDARD SPECIFICATIONS 09 65 37 - PAGE 6 OF 7 MARCH 29, 2013 surfaces are free from soil, static-control adhesive, and surface blemishes. Do not apply standard wax. a. Verify that both floor polish and its application method are approved by manufacturer and that floor polish will not leave an insulating film that reduces static-control resilient flooring's effectiveness for static control. F. Provide final cleaning – at final acceptance, as directed by Owner.
