E. Continue burnishing operations until the specified gloss is attained. Achieve specified gloss no later than two
weeks prior to Re-Grand Opening and maintain specified gloss until Re-Grand Opening.
F. Provide final burnishing prior to Grand Opening as required to eliminate damage from subsequent work.
3.5 FINISH REQUIREMENTS
A. Gloss: Final surface gloss shall be a Specified Overall Gloss Value (SOGV) of not less than 40 and a Minimum
Local Gloss Value (MLGV) of 30 as measured using a Horiba IG-320 Gloss Checker.
B. Slip Resistance: Measured static coefficient of friction (SCOF) shall be not less than 0.50 at time of Re-Grand
Opening as measured using an American Slip Meter ASM 825 Digital Meter, Regan Scientific Instruments BOT-
3000 Tribometer, or approved equal.
3.6 PROTECTION
A. Protect areas to receive polished concrete finish at all times during construction to prevent oils, dirt, metal, excessive
water, paint and other potentially damaging materials from affecting the finished concrete surface. Protective
measures listed below shall begin immediately after completion of polishing.
1. Communicate to all subcontractors, vendors, and trades importance of maintaining slab protection at all
times.
2. Protect slab surface from moisture for 72 hours to prevent re-emulsification of protective surface treatment
prior to cure. Verify that all wood pallets are dry prior to replacing.
3. Each day, inspect all equipment used over completed slab surface, to insure:
a. Equipment is without leaking hydraulic lines and is diapered to avoid staining. Remove all equipment
with hydraulic fluid leaks from store site.
b. No tire embedments (rocks, nails, screws, etc.) that will scratch or pit slab surface.
4. Prevent contact with acids and acidic detergents.
5. Use breathable surface protective materials for high traffic areas.
a. EZ-Cover, by McTech Group, (866) 913-8363.
b. Ram Board, by Ram Board, (818) 848-0400.
6. Use breathable drop cloths during all painting. Immediately wipe clean spilled paint.
3.7 QUALITY ASSURANCE TESTING
A. Testing will be performed by the Wal-Mart Construction Testing Laboratory (CTL) at no expense to the Contractor.
A test report of all measurements and a plan and table of the measurements taken shall be prepared by the
CTL for submittal.
B. General Contractor shall notify CTL when slab is ready for testing.
C. Take gloss measurements once weekly. Gloss shall be considered as a quantitative value that expresses the degree
of reflection when light hits the concrete floor surface. Gloss measurements will be taken independent of ambient
lighting and within a sealed measurement window located beneath the testing equipment. Measurement and reporting
of SOGV and MLGV by CTL shall be as follows:
1. Collect a minimum of five samples per each bay, in random, evenly distributed locations. Record measurement
locations on copy of Floor Burnishing Plan. Discard the high and low values measured in each
bay.
2. The average of all samples collected in each bay shall meet SOGV.
a. If the average of samples collected do not meet the SOGV, collect an additional 3 samples in each
bay for each deficient result unless the individual samples fail to meet the MLGV or the average of
all collected samples in each bay fail to meet the SOGV.
b. If samples fail to meet the SOGV, Contractor shall continue burnishing until the SOGV is achieved.
3. No single measured value shall be less than MLGV.
