The l area of inspection shall be adequately lighted during the inspection activi ty. Adequate lighting is defined as the minimum light produced by a two (2) cell battery flashlight.
If a conflict arises between the requirenents of this procedure and the requirements of the site specification, Reference 1-A, the requirenents of the site specification shall prevail .
3.1 SURFACE PREPARATION The concrete surface shall be cured a minimum of 28 days prior to application of protective coatings. If the concrete surface is cured with NUTEC 10, coating may be perfonned after a minimum of 6 days after application of NUTEC 10.
Tie holes, abandoned Hilti bolt holes and spalled concrete as defined in Reference 1-B, and patched per Reference 1-C and l grout under base plates which has 3 square feet or less of exposed surface to be coated, may be coated af ter a 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> cure.
3.1.1 Preblast Cleaning Operations Prior to su rface prepa ration, the QC inspector shall visually examine the surface to be water blasted for heavy deposi ts of oil and grease. Any heavy oil or grease deposits shall be removed by steam cleaning, tri sodium phosphate washing wi th a mixture of 3-6 pounds TSP per gallon of water, or use of an Imperial recommended detergent.
The QC inspector shall alto verify tnat any detrimental surface irregularities such as projections, fins, or ridges shall be renoved by bush hammering, hand or power tooling, grinding, or stoning.
NOTE 1: The preblast visual inspection is required only when surface preparation is by one of the following methods:
- a. Water blasting
- b. Water blasting with sand injection
- c. Dry sandblasting
- d. Bush hammering e~.... TuGCO OA

surface shall be abraded without completely removing the NUTEC 10 prior to application of the surfacer. !
The QC inspector shall note the method (s) used on the Inspection Report (IR), Attachment 1. The inspector shall verify' that the method (s) used are in compliance with ,
Reference 1-0. In the event TSP is used, the QC inspector i shall verify that the area is flushed with clean water. If sand blasting is used, the QC inspector shall verify that a trap, filter, or separator is installed in the air line.
3.1.3 Post Surface preparation Operations Af ter surface preparation, the QC inspector shall visually examine the si.rface to verify the following:
a) The surface shall be free of construction dust, laitance, and loose deposits, and all adjacent areas cleaned to avoid contamination.
b) All holes greater than 1/2 inch in depth or greater than 2" diamettr and cracks greater than 1/32" width are repaired prior to surfacer application.
c) All sharp projections removed.
d) Markings ('nk, pencil, chalk, fel t tip marker, etc.)
solvent wiped in accordance with Reference 1-0. l e) Marking pairt renoved, f) Objects protruding fran surface are ground or cut smooth until object is flush, g) Al l loosely adhering objects enbedded are renoved ,

If grease and oil renain af ter TSP cleaning, the area shall be chipped out and repaired with dry pack or epoxy grout and insp2cted by Civil QC in accordance with Reference 1-E. l 3.2 MIXING OPERATIONS 3.2.1 Materials The QC inspector shall verify' that the materials to be used are in accordance with Reference 1-D and that each component is identi fied by a ba tch ntsnbe r. The QC inspector shall also verify that the shelf life (See Attachment 2) has not expired. NUTEC 10 has an expiration date marked on the container and it shall not be used after that date.
3.2.2 Mixing / Thinning The QC inspector shall wi tness all mixing / thinning operations, and verify that mixing / thinning is performed in accordance with Reference 1-0. Induction times for finish mixes are shown in Attachment 2.
3.3 SURFACER APPLICATION 3.3.1 Ambient Conditions The inspector shall detennine air tenpe ra tu re, rela tive humidi ty, dew poin t, and su rface temperature of concrete substrate. A calibra ted non-me rcury filled dry bulb thennometer or a calibrated tenperature recorder (Bristol 4069 TH or equivalent) shall be used for air tenperature detennination. A calibrated non-mercu ry filled wet bulb thennome ter or a calibra ted humidi ty recorde r (Bristol 4069 TH or equivalent) shall be used to determine rela tive humidi ty. The dew point shall be detennined by the dif ference in dry and wet bulb temperature using the U.S.
Department of Commerce Weather Bureau Psychrometric Tables, W.B. No. 235. When dry bulb readings are greater than 100*F, the dew point and relative humidity should be detennined using the 100'F reading (note in Remarks Section). The surface tenperature shall be detennined by placing a calibrated Range 0-250'F thermometer or equivalent in contact with the surface to be coated. The thennometer probe shall renain in contact with the surface until the tenperature reading stabilizes.
