I 3.1.1 Preblast Cleaning Operations Prior to surface preparation, the QC ins pector shall i visually examine the surface to be water blasted for heavy deposits of oil and grease. Any heavy oil or grease deposits shall be removed by steam cleaning, trisodium a phosphate washing wi th a mixture of 3-6 pounds TSP - pe r

gallon of water, or use of an Imperial recommended detergent.

J The QC inspector shall also verify that 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 reautred only when surface preparation is by one of the following methods:

a. Water blasting

b. Water blasting with sand injection

c. Dry sandblasting

d. 84h hammering 3.1.2 Surface Preparation 3.1.2.1 Methods of Surface Preparation

~

Water blasting, water blasting with sand injection, acid etching, sand blasting, and power tooling are all acceptable methods of surface preparation. If NUTEC 10 curing membrane has been applied and gives a " glossy" appearance, the 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) us ed are in et eliance with Reference 1-A. In the event TSP is used, the QC inspector 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.

examine the surface to verify the following

a) The surface shall be free of cons truction dus t, i laitance, and loose deposits, and all adjacent areas i cleaned to avoid contamination.

~

b) All holes greater than 1/2 inch in depth are repaired wi th dry pack or epoxy grout in accordance wi th Reference 1-B.

3 c) All sharp projections removed.

l d) Markings (ink, pencil, chalk, felt tip marker, e tc. )

! solvent wiped in accordance with Reference 1-A.

e) Marking paint removed in accordance with Reference 1-A.

f) Objects protruding from surface are ground or cut smooth until object is flush.

g) All loosely adhering objects embedded are removed.

h) Smooth embedded objects such as plastic or s teel roughened. Metal objects are power tool cleaned and solvent wiped.

1). Metal objects larger than 4 square inches are primed in accordance with Reference 1-C.

. j) Surface is free of grease, oil, and curing membranes.

If grease and oil remain after TSP cleaning, the area shall be chipped out and repaired with dry pack or epoxy grout and inspected by Civil QC in accordance with Reference 1-8.

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-A and 1-F and that each <

component is identified by a batch number. 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 af ter that date.

3.3 SURFACER APPLICATION 3.3.1 Ambient Conditions The inspector shall determine air temperature, relative humidity, dew point, and surface temperature of concrete l subs trate. A calibrated non-mercury filled dry bulb themometer or a calibrated temperature recorder (Bristol i 4069 TH or equivalent) shall be used for air temperature determination. A calibrated non-mercury filled wet bulb ,

thennometer or a calibrated humidi ty recorder (Bris tol 4069 TH or equivalent) shall be used to determine relative humidity. The dew point shall be detemined by the difference 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 detemined using the 100*F reading (note in Remarks Section). The surface temperature shall -be detemined by placing a calibrated Range 110*F thermometer or equivalent in contact with the surface to be coated. The thennometer probe shall remain in contact

, with the surface until the tenperature reading stabilizes.

Minimum and maximum values of surface and ambi ent temperatures shall be 50*F and 100*F res pectively.

Infrequent dips in temperature-to 40*F is pemissible durir.g application and/or cure; however, the elapsed time the temperature is below 50*F shall be added to the cure time.

Application of the coating shall not begin unless the surface tenperature is 5'F above the dew point. Pot life shall be as stated in Attachment 2.

Humidity may vary as high as 100%; however, free standing water shall be removed. Coating application over a da'np surface is pemissible. Under no conditions shall NUTEC 11S be applied to a surface containing free standing water.

Methods of identifying free standing water are shown in '

3.3.3 Air Supply Acceptability 1

The inspector shall ins pect the air supply sys tem for pressure pots and spray guns for suitable filters / traps /

separators . The effectiveness of these items shall be verified by exposing a piece of white paper or cloth to a e

blast of air for approximately 30 seconds. The cloth shall show no evidence of moisture, oil or foreign matter when

{ examined.

3.3.4 pot Life The QC inspector shall verify that the pot life as ,shown in Attachment 2 is not exceeded.

3.3.5 Qualification of Aeolicator(s)

The Inspector shall verify (by Qualification Record or list of qualified applicators from QA file) that the coating applicators on each shift are qualified for safety-related coating work.

3.3.6 Dry Film Thickness The QC inspector shall detennine the DFT of the applied

. surfacer by taking wet film thickness spot measurements and

alltiplying each reading by the ". volume solids (taking in account any thinner used). A minimum of five (5) separate spot wet film thickness (WFT) measurements (See Note 1) spaced evenly over the coated area (See Note 2) shall be ;

taken.

NOTE 1: A spot measurenent is a series of three measurements in the same general area. The WFT gage should be moved a short distance for each gage reading. Discard any unusually high or low

, gage reading that cannot be repeated consistently.

' The inspector shall determine air temperature, relative humidity, dew point, and surface temperature of concrete substrate. A calibrated non-mercury filled dry bulb thermometer or a calibrated temperature recorder (Bristol 4069 TH or equivalent) shall be used for air temperature detemination. A calibrated non. mercury filled wet bulb thermometer or a calibrated humidity recorder (Bristol 4069 TH or equivalent) shall be used to determine relative humidity. The dew point shall be detemined by the difference in dry and wet bulb temperature using the U.S.

Department of Commerce Weather Bureau Psychrometric Tables, i

W.B. No. 235. When dry bulb readings are greater than 100*F, the dew pint and relative humidity should be determined using the 100 F reading (note in Remarks Section). The surface temperature shall be detemined by placing a calibrated Range O.110*F thermometer cr equivalent in contact with the surface to be coated. The thermometer probe shall' remain in contact with the surface until the temperature reading stabilizes.

Mintmum and maximum values of surface and ambient temperatures shall be 50*F ano 100*F respectively.

1 Infrequent dips in temperature to 40*F is permissible during l application - and/or cure; nowever, the elapsed time the temperature is below 50*F shall be added to the cure time.

Application of the coating shall not begin unless the surface temperature is 5'F above the dew point.

4 Pot life shall be as stated in Attacnment 2.

Humidity may vary as high as 100%; however, free standing

+

water shall be removed. Coating application over a damp surface is permissible. Under no conditions shall NUTEC 11S be applied to a surface containing free standing water.

Methods of identifying free standing water are shown in Reference 1 A.

Minimum and maximum values of surface and ambient temperatures shall be 50*F and 100*F respectively.
Infrequent dips in temperature to 40'F is permissible during application and/or cure; however, the elapsed time the temperature is below 50*F shall be added to the cure time.
Application of the coating shall not begin unless the surface temperature is 5'F above the dew point. Pot life shall be as stated in Attachment 2.
Humidity may vary as high as 100%; however, free standing j water shall be removed. Coating application over a damp surface is pennissible. Under no conditions shall NUTEC 115 be applied to a surface containing free standing water. i Methods of identifying free standing water are shown in Reference 1-A.
3.3.2 Surface Acceptability The QC inspector shall visually examine the substrate r
surface immediately prior to surfacer application to verify that it is free of contamination (dust, laitance, and loose deposits).
l 3.3.3 Air Supply Acceptability The inspector shall inspect the air supply system for '
pressure pots and spray guns for suitable filters / traps / !
separators.
The effectiveness of these items shall be ,
verified by exposing a piece of white paper or cloth to a j blast of air for approximately 30 seconds. The cloth shall '
show no evidence of moisture, oil or foreign matter when examined. j 3.3.4 Pot t.ife l t
