The dew point shall be detemined by the difference in dry and wet bulb temperature using the U.S. Department of Commerce Weather Bureau Fsychrometric 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 temperature 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 cenuin in contact with the surface until the taperature reading stabilizes.

Minimum and maximum values of surface and ambient ,

taperatures shall be 50*F and 100*F respectively.

Infrequent dips in tenperature to 40*F is pennissible 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 tenperature is 5'F above the dew point.

Humidity may vary as high as 1001; however, free standing ,

water shall be removed. Coating application over a damp surface is pennissible. Under no conditions shall NUTEC 115 or Nutec 11 be applied to a surface containing free standing water. (ReferenceAttachment6). .

c. The lead inspector (s) shall review the log sheets for completeness and correctness, sign and date the "QC Review" block, obt'ain copies for QC reference and transmit the originals to the Paper Flow Group.

d. If at any time the. inspector detennina readings which do not comply with the parameters set forth in this procedure, he shall proceed in the following manner:

1. Immediately take an additional set of readings in the immediate area of the first set of unacceptable readings and record then on the Envirorsnental Log.

2. If the additional set of readings are acceptable, take a third set of readings for referee purposes and record them. If the referee set of readings are acceptable, then the area in question is acceptable ~ but should be closely monitored with readings as necessary.

3. If the additional set of readings is unacceptable and/or the referee set of readings is unacceptable, the inspector is to notify the coatinge inspectors in the areas affected so that coating work may be stopped at that time. Coating work shall not continue until the ambient conditions resume an acceptable status.

4. When unacceptable ambient conditions occur and are verified by Step 3 above, the Inspector shall documant it on a Nonconfonnance Report (NCR) in accordance with Reference 1-C, and adequately identify the affected armas/ elevations.

DEFINITIONS Color and Gloss Nonunifonnity

A milky haze or mist in the finish of a recently applied coating.

Contaminant: A foreign substance, inadvertently added to a coating or found on the substrate that adversely affects the application, adhesion, curing and/or subsequent perfonnance of the applied coating.

Dry Soray: A dry powdery primer or finish coat readily renoved by lignt sanding with either sandpaper or a wire screen. A minor amount of adherent dry spray is acceptable on the final finish coat.

Feathering: An area that is roughened and tapered to obtain a smooth and continuous surface with an existing damaged coating.

Fisheyes: Small openings (" fish eyes") in wet film exposing old surface or previous coat.

• 4

' Free Standing Water: May be identified by:

a. Reduced vi scosity of the surfacer during application, and i

excessive sagging fran bug holes.

b. Wet rings around bug holes,

c. Visible signs of surface water.

d. Running hand over the surface resulting in moisture on the hand.

e. Product instability resulting in white streaks.

4

f. Failure of the surfacer to adhere to the substrate during the sqeegeeing or troweling process.

Full Hiding: The coating provides sufficient coverage so that the preceding coat is not readily visible with an unaided eye.

Holiday: A pinhole, skip, discontinui ty or void in coating film.

Laitance: A fine, ditish acctmulation on concrete surfaces. It con-sists mainly of cement particles that were carried by water rising to the surface of freshly placed concrete. The resulting concrete surface is unsuitable for proper adhesion or bond of subsequent fillers or protective coatings.

Monitor: Confonnance verification by physically observing a task being perfonned on a periodic or random basis. 1 9

Muderacking: Irregular cracking as in a dried mud puddle.

l Orange Peel: Dents in the surface resembling orange skin. A moderate amount is acceptable.

Over Spray: A deflected spray mist that settles on dry or partially dry coated surfaces.

Pinnoles: Minor discontinuities in coating dich expose primer or suostrate.

Verify: Confirm or make certain.

j PREPARATION OF COATING MATERI ALS 4

i Surfacer Coat f

i The surfacer, NUTEC 11S, is packaged in a three camponent i kit consisting of a base, curing agent, and filler. The j base and curing agent 'shali be thoroughly mixed first. If i necessary, box the mixture to assure that all the base and cure has been used. The filler shall then be slowly added under constant agitation and mixed until a smooth blend is

. achieved. The patching storial NUTEC 11,'is prepared the i same way. Partial mixes for NUTEC 115 shall be in accordance l with Attachment 7A. No provision is given for partial mixes l of NUTEC 11. '

4 2

( Finish Coat I<

The finish coat, NUTEC 1201, is a two caponent epoxy 4

topcoat consisting of a base and cure. These shall be thoroughly mixed under constant agitation until a homogenous f

' blend is achieved. Partial mixes of NUTEC 1201 shall be in accordance with Attachment 78. Minimum induction times i shall be as per Attachment 2.

SEALER / CURING COMPOUNO The sealer / curing *capound, NUTEC 10, is nonnally a two caponent material consisting of a base and a curing agent.

4 If applying to surfaces below 60* F, a third caponent

accelerator may be used. Slowly six by power agitation or

• by hand the entire volume of the cure caponent with the entire volume of the base caponent. If an accelerator is

', used, add the premeasured portion to the base-cure mixture

' and agitate slowly. Avoid rapid agitation which may result i in air entrapment. Thinning may be perfonned by adding fra j 10 405 by volume #0L-56 solvent. Do not vary mixing

proportions.

Dry Spray:

A dry powdery primer or finish coat readily renoved by light sanding with either sandpaper or a wire screen. A minor amount of adherent dry spray is acceptable on the final finish coat.

i Feathering: An area that is roughened and tapered to obtain a smooth and continuous surface with an existing damaged coating.

Fisheyes: Small openings surface or previous coat.(" fish eyes") in wet film exposing old Free Standing Water: May be identified by:

a. Reouced viscosity of the surfacer during application, and excessive sagging fra bug holes,

b. Wet rings around bug holes.

PREPARATION OF COATING MATERIALS i

4 Surfacer Coat The surfacer, NUTEC 115, is packaged in a three camponent kit consisting of a base, curing agent, and filler. The base and curing agent shall be thoroughly mixed first. If necessary, box the mixture to assure that all the base and

' cure has been used. The filler shall then be slowly added under constant agitation and mixed until a smooth blend is achieved. The patching saterial, NUTEC 11, is prepared the same way. Partial mixes for NUTEC 115 shall be in accordance

, with Attachment 7A. ho provision is given for partial mixes 4

of NUTEC 11. l 1

j Finish Coat i

i j

The finish coat, NUTEC 1201, is a two ca ponent epoxy ,

topcoat consisting of a base and cure. These shall be thoroughly mixed under constant agitation until a homogenous 4

i blend is achieved. Partial mixes of NUTEC 1201 shall be in accordance with Attachment 78. Minimum induction tiras shall be as per Attachment 2.

i SEALER / CURING COMPOUND The sealer / curing campound, NlffEC 10, is nonnally a two

' component material consisting of a base and a curing agent.

' If applying to surfaces below 60* F, a third ca ponent accelerator may be used. Slowly six by power agitation or  ;

by hand the entire volume of the cure camponent with the entire volume of the base camponent. If an accelerator is l

t used, add the preseasured portion to the base-cure mixture i

and agitate slowly. Avoid rapid agitation which may result in air entrapnent. Thinning nay be perfonned by adding fram

10-405 by volume #0L-56 solvent. Do not vary mixing

,i proportions. j l *

NUTEC 115, is packaged in a three canponent kit consisting of a base, curing agent, and filler. The base and curing agent shall be thoroughly mixed first. If necessary, box the mixture to assure that all the base and cure has been used. The filler shall then be slowly added under constant agitation and mixed until a smooth blend is achieved. The patching storial, NEEC 11, is prepared the same way. Partial mixes for NUTEC 115 shall be in accordance with Attachment 7A. No provision is given for partial mixes

of NUTEC 11. l Finish Coat The finish coat. NUTEC 1201, is a two camponent epoxy topcoat consisting of a base and cure. These shall be thoroughly mixed under constant agitation until a homogenous blend is achieved. Partial mixes of NUTEC 1201 shall be in accordance with Attachment 78. Mini:num induction times shall be as per Attachment 2.

' SEALER / CURING COMPOUND The sealer / curing canpound, NW EC 10, is nonnally a two component material consisting of a base and a curing agent.

If applying to surfaces below 60' F. a third camponent accelerator may be used. Slowly mix by power agitation or by hand the entire volume of the cure component with the entire volume of the base component. If an accelerator is used, add the preneasured portion to the base-cure mixture and agitate slowly. Avoid rapid agitation which may result in air entrapment. Thinning my be perfonned by adding fram

, 10-40% by volume #0L-56 solvent. Do not var / mixing propo rtions.
