PART 3 EXECUTION

3.1 PREPARATION

3.1.1 Coating Hazards

Ensure that employees are trained in all aspects of the safety plan.

Specified coatings may have potential health hazards if ingested or improperly handled. Follow the coating manufacturer's written safety precautions throughout mixing, application, and curing of the coatings.

During all cleaning, cleanup, surface preparation, and paint application phases, ensure that employees are protected from toxic and hazardous chemical agents which exceed concentrations in 29 CFR 1910.1000 . Comply with respiratory protection requirements in 29 CFR 1910.134 .

For faying surfaces that become inaccessible after installation, abrasive blast and coat with inorganic zinc only, prior to installation.

Surfaces that are part of slip-critical joints are [abrasive blasted] [mechanically cleaned coated with inorganic zinc] prior to installation.

Leave surfaces to be welded uncoated. Welded areas are then masked and touched up.

Coat prepared surfaces within 6 hours after completion of surface preparation and before rusting or recontamination occurs. Re-prepare surfaces not coated within 6 hours or which show rusting or contamination, regardless of the length of time after preparation.

Sequence surface preparation and coating operations so that freshly applied coatings are not contaminated by dust or foreign matter.

Inspect and degrease surfaces as required prior to subsequent surface preparation and the application of protective coatings. Degreasing is by solvent cleaning, detergent washing, or steam cleaning. SSPC SP 1 applies for solvent cleaning.

3.1.3 Abrasive Blasting (AB)

Ensure abrasive blasting conforms to SSPC SP 10/NACE No. 2 and SSPC Painting Manual .

Ensure compressed air used for abrasive blasting is free of moisture and oil.

Surfaces not to be blasted are:

a. Galvanized steel and prefinished surfaces except when specified to be blast-cleaned in the coating schedule

b. Piston rods and bearing surfaces

Maintain a minimum nozzle pressure of 620 kilopascal 90 pounds per square inch .

SECTION 09 97 13.00 40 Page 9

Remove weld slag, weld spatter, and foreign matter from surfaces to be coated prior to abrasive blasting using mechanical methods as specified.

Ensure blast cleaning achieves a 0.025 to 0.050 millimeter 1-to 2-mil anchor profile as indicated by a surface profile comparator, replica tape, or similar device.

Remove rust and corrosion from pits and depressions.

Do not reuse abrasive blast aggregate.

Remove all traces of abrasive residue and dust from the surface, leaving it clean and dry.

3.1.4 Mechanical Cleaning (MC)

Where mechanical cleaning is specified in the coating schedule [for existing surfaces] [and AB is prohibited], use needle scalers or abrasive disks or wheels in accordance with SSPC SP 3 , leaving the surface cleanliness equivalent to near-white metal ( SSPC SP 10/NACE No. 2 ).

3.2 APPLICATION

3.2.1 General Requirements

Manufacturer's instructions for thinning, mixing, handling, and applying products are considered a part of this specification. In the event of conflict between the requirements of this specification and the manufacturer's recommendations, this specification takes precedence.

Ensure compressed air used for spraying coatings remains free of moisture and oil.

Ensure each coat of material applied is free from runs; sags; blisters;

bubbles; mud cracking; variations in color, gloss, and texture; holidays (missed areas); excessive film build; foreign contaminants; and dry overspray.

Do not apply coating when rain is imminent or when the temperature or humidity is outside the limits recommended by the coating manufacturer.

Ensure the surface temperature is at least 3 degrees C 5 degrees F above the dew point.

Work coatings thoroughly into all joints, crevices, and open spaces. Pay special attention to welds, cutouts, sharp edges, rivets, crevices, and bolts to ensure proper coverage and thickness.

Protect newly coated surfaces from damage.

Apply coatings by airless or conventional spray. Use airless spraying for uniform large surface areas. Use conventional spraying for small areas of intricate configuration and for touchup. During application of inorganic zinc coating , maintain uniform suspension.

3.2.2 Mixing and Application Procedures

Stir material thoroughly using an instrument that does not induce air into

SECTION 09 97 13.00 40 Page 10 coating.

Strain mixed material through a 250- to 600- micrometer 30- to 60-mesh screen.

Provide continuous slow agitation of the material during application of inorganic zinc coating, maintain uniform suspension. Avoid continuous rapid agitation.

Thin material for workability and improved spray characteristics only.

Apply material in even, parallel passes, overlapping 50 percent. Pay special attention to welds, cutouts, sharp edges, rivets, crevices, and bolts to ensure proper coverage and thickness.

3.2.3 Dry-Film Thickness (DFT)

Apply coatings to the following dry-film thicknesses:

Coating System No. 1:

a. Inorganic primer zinc: 0.060 to 0.102 millimeter 2.5 to 4 mils [ 3 to 6 mils, inorganic zinc, as specified in Coating Schedule.]

b. Inhibitive polyamide epoxy, second coat: 0.051 to 0.0102 millimeter 2 to 4 mils .[ Top coat [_____] 0.051 to 0.102 millimeter 2 to 4 mils .]

c. Aliphatic polyurethane, third coat: 0.051 to 0.0102 millimeter 2 to 4 mils , but sufficient to hide previous coat [Second coat, inorganic zinc, 0.051 to 0.102 millimeter 2 to 4 mils .]

[ Coating System No. 3: When thoroughly dry (dry to handle), check the film thickness with a calibrated nondestructive dry-film thickness gage. If less than specified thickness, apply additional material as required.

Obtain proper DFT for the inorganic zinc coating in a single application which may consist of multiple passes, while coating is still wet.

] 3.2.4 Touch-Up

Touch-up abrasions that occurred during shipment or erection as follows:

a. Ensure surface preparation and coating application conforms to the manufacturer's instructions.

b. Use inorganic zinc for touch-up and repair of inorganic zinc and hot-dip galvanizing .

c. Use inhibitive polyamide epoxy and aliphatic polyurethane for touch-up and repair of coating system No. 2.

3.2.5 Sealant Compound Application

For Coating System No. 1, accomplish caulking after application and cure of inorganic zinc coating.

For Coating System No. 2, accomplish caulking after application and cure of inhibitive epoxy coat and prior to aliphatic polyurethane coat.

Caulk exterior joints, including, but not limited to, the following:

SECTION 09 97 13.00 40 Page 11

a. Perimeter of faying and bearing surfaces of structural members

b. Joints in members between intermittent welds

c. Perimeter of bearing surfaces between floor plates and supporting members (inside, outside, top, and bottom)

d. Stair treads, where joined to channel stringers

e. Openings of 13 millimeter 1/2 inch or smaller (Use foam filler backup as required.)

f. Hot-dipped galvanized vent holes

3.3 FIELD QUALITY CONTROL

3.3.1 Inspection

On-site work as described herein is inspected for compliance with this specification by a NACE (National Association of Corrosion Engineers) Certified Coating Inspector provided by the [Contracting Officer] [Contractor].

For all protective coatings applied off-site locations, provide full inspection by NACE Certified Coating Inspector. Ensure the inspector is present at the pre-work conference to address necessary clarification of inspection and specification requirements. Report immediately any apparent deviation from the specified requirements or any out of tolerance condition to the Contracting Officer for determination of corrective action. Submit the inspection reports performed by the Coating Inspector.

3.3.2 Inspection Forms

Submit inspection forms at the pre-work conference which are used by the Coating Inspector and forwarded to the Contracting Officer prior to delivery of the coated work to the job site.
