           following requirements for substrate conditions. Do not proceed until unsatisfactory conditions have been
           1.     Verify concrete floors are free of excessive moisture, hydrostatic pressure, alkalinity, scale, and dusting.
           2.     Verify concrete floors are plane to tolerances specified in Section 03312.
           3.     Verify concrete floors are free from oil, grease, dust, construction debris, loose or scaly paints or coatings,
                  incompatible curing or sealing compounds, and other substances that may impair adhesion of adhesive and
                  finish materials.
           4.     Verify temperature of conditioned space has been maintained at 60 - 80 degrees F for period of 7 days prior

      D.   Provide finish concrete surface smooth by light sanding or grinding.

      E.   Remove paint, oils, waxes, sealers and curing compounds not compatible with adhesive to be used. Avoid organic
           solvents or liquid adhesive removers.

      F.   Bond Test: Determine suitability of concrete substrate for receiving resilient flooring with regard to moisture
           content and curing compounds. The Contractor shall conduct bond tests by adhering 3 feet by 3 feet panels of
           specified floor covering with specified adhesive. Test will be considered passed if after several days panels are
           well bonded, difficult to remove, and display no signs of moisture or adhesive degradation.

      G.   Moisture Content and pH Tests: Moisture content tests and pH tests will be conducted by Owner’s Construction
           Testing Laboratory (CTL) at no cost to the Contractor. Moisture tests will be made to ensure that moisture content
           in concrete substrate does not exceed 5 percent as measured by the Calcium Carbide Hygrometer Procedure or 5
           pounds/1000 sq. ft./24 hours as measured by the Rubber Manufacturers Association Quantitative Calcium
           Chloride Test. Tests shall be taken in sufficient number and locations as required to obtain results representative of
           various areas to be covered by resilient flooring. Contractor shall notify the ITL when slab is considered
           sufficiently dry for testing. The ITL shall report test results to the Wal-Mart Construction Manager. Final tests
           shall be taken not more than 24 hours prior to application of flooring.

      H.   Prohibit traffic until filler is cured. Thereafter, unnecessary traffic in work areas shall be kept to a minimum.


      A.   Install resilient flooring in accordance with manufacturer's published instructions at locations indicated on Wal-
           Mart Carpet/Tile Plan.

      B.   Open number of floor material cartons to provide quantity required to cover each area; mix pieces within single
           shade lot to ensure shade variations do not occur within any one area. When working with more than one lot, plan
           lot placement and location to minimize possible shade differences.

      C.   Apply adhesive in accordance with manufacturer’s directions. Follow adhesives open time by spreading only
           enough adhesive to permit installation of floor materials before initial set. Do not spread adhesive for overnight

      D.   Plank Flooring Installation:
           1.     Install plank strips from side-to-side, not front-to-back, of store.

                  pieces and alternate the size of the starter piece to avoid a repeating joint pattern. The shortest starter piece
                  shall be not less than 12”.
           3.     Overall plank flooring layout shall produce a complete random appearance of joint spacing, with end joints
                  staggered a minimum of 6” apart.

      E.   Wipe down adhesive bleed through during installation.

      F.   Rolling: Set flooring into place, thoroughly cross roll with a 100-150 pound three-sectional roller before adhesive
           set time expires to attain full adhesion.

      G.   Terminate flooring at centerline of door openings where adjacent floor finish is dissimilar. Where flooring
           continues through door opening, continue established pattern with no interruption.

      H.   Install transition strips at unprotected or exposed edges where flooring terminates.
           1.       Set metal transition strips butted to adjacent flooring. Anchor into concrete slab with specified fasteners
                    spaced at 6” on center unless otherwise shown on the drawings. Drill concrete with Matched Tolerance
                    Drill Bit for Dense Concrete by Hilti.

      I.   Scribe flooring to walls, columns, cabinets, floor outlets, and other appurtenances to produce tight joints.

           manufacturer's requirements for substrate conditions. Do not proceed until satisfactory conditions have been

      C.   Cleaning PVC
           1.     Clean PVC flooring with a commercial flooring cleaner using mop or scrubber with white pads.
           2.     Apply stripper only as necessary to remove adhesive bleed-thru.
                  a.     Apply diluted stripper solution liberally to a manageable area of the floor and let solution set for 10
                         minutes prior to scrubbing. Do not allow the stripper to dry. Re-wet as necessary.
           3.     Pick up cleaning or stripper solution from floor using the auto scrubber with clear water and red pads.
           4.     Thoroughly rinse the floor to remove any residue of cleaning or stripper solution.
           5.     Let floor dry completely prior to application of floor finish.
