A. General:

1. Mix and prepare painting materials in strict accordance with the manufacturer's

directions.

2. Do not mix coating materials produced by different manufacturers, unless otherwise

permitted by the manufacturer's instructions.

3. Store materials not in actual use in tightly covered containers. Maintain containers

used in storage, mixing and application of paint in a clean condition, free of foreign

materials and residue.

4. Stir all materials before application to produce a mixture of uniform density and as

required during the application of the materials. Do not stir any film, which may

form on the surface into the material. Remove the film and, if necessary, strain the

material before using.

3.04 APPLICATION

A. General:

1. Apply paint by brush or roller. Other mechanical application techniques such as

power roller, air spray, or airless spray in accordance with the manufacturer's

directions and recommendations of Paint Application Specifications No. 1 in SSPC

Vol. 2, where applicable shall be used only as reviewed by the Engineer. Use

brushes suited for the type of material being applied. Use rollers of carpet, velvet

back, or high pile sheeps wool as recommended by the paint manufacturer for

material and texture required.

2. The number of coats and paint film thickness required is the same regardless of the

application method. Do not apply succeeding coats until the previous coat has

completely dried.

3. Apply additional coats when undercoats, stains, or other conditions show through the

final coat of paint, until the paint film is of uniform finish, color and appearance.

This is of particular importance regarding intense primary accent colors. Insure that


AECOM REBID

surfaces, including edges, corners, crevices, welds, and exposed fasteners receive a

film thickness equivalent to that of flat surfaces.

4. Use of thinners at any time shall have prior review of the Engineer.

B. Minimum Coating Thickness: Apply each material at not less than the manufacturer's

recommended spreading rate and provide total dry film thickness as specified. Apply extra

coat if required to obtain specified total dry film thickness.

C. Scheduling Painting:

1. Apply the first-coat material to surfaces that have been cleaned, pretreated or

otherwise prepared for painting as soon as practicable after preparation and before

subsequent surface deterioration.

2. Allow sufficient time between successive coatings to permit proper drying. Do not

recoat until paint has dried to where it feels firm, does not deform or feel sticky under

moderate thumb pressure and the application of another coat of paint does not cause

lifting or loss of adhesion of the undercoat.

D. Prime Coats: Recoat primed surfaces where there is evidence of holiday (thinning) areas in

first coat, to assure a finish coat with no burn-through or other defects caused by insufficient

sealing.

E. Pigmented (Opaque) Finishes: Completely cover to provide an opaque, smooth surface of

uniform finish, color, appearance and coverage.

F. Brush Application:

1. Brush-out and work all brush coats onto the surfaces in an even film. Cloudiness,

spotting, holidays, laps, brush marks, runs, sags, ropiness or other surface

imperfections will not be acceptable.

2. Brush apply all primer or first coats, unless otherwise permitted to use mechanical

applicators.

G. Mechanical Applicators:

1. Use mechanical methods for paint application when permitted by governing

ordinances, and paint manufacturer. Limit to only those surfaces impracticable for

brush applications.

1. Limit roller applications to exterior wall finishes for second and third coats. Apply

each roller coat to provide the equivalent hiding as brush-applied coats.

3. Confine spray application to metal framework, siding, decking, wire mesh and

similar surfaces where hand brushwork would be inferior to other surfaces

specifically recommended by paint manufacturer.

4. Wherever spray application is used, apply each coat to provide the equivalent hiding


AECOM REBID

of brush-applied coats. Do not double back with spray equipment for the purpose of

building up film thickness of 2 coats in one pass.

H. Completed Work: Match approved samples for color, texture and coverage. Remove,

refinish, or repaint Work not in compliance with specified requirements.

I. Painted Work:

1. Undercoats shall be of approximate shade of final coat, but each coat shall be of

slightly different tint. Each coat shall be inspected and approved before application

of the succeeding coats, otherwise no credit for coat applied will be given and the

work in question shall be recoated.

2. Finished surface shall be uniform in finish and color and free from brush marks,

sagging, rippling and other imperfections. Should any coat be judged unsatisfactory,

the coat shall be sandpapered or otherwise cleaned off and another coat applied. If

the undercoating is disturbed, complete refinishing will be required.

3. Finish all returns, edges and recesses which will be exposed in the finished work and

which will be seen from any angle to match the adjacent work.

4. Edges of paint or finish adjoining other materials or colors shall be sharp and clean

without overlapping. Should workmanship be found defective, proper preparatory

work shall be done and additional coats applied as necessary to give a finish in

accordance with specified requirements.

J. After completion of each coat of paint, notify the Engineer. After inspection, checking of film

thickness and acceptance by Engineer, proceed with the succeeding coat. Purchase for the

Engineer two new wet-film and one new dry-film thickness gages for checking the film

thickness and one set of visual standards to check surface preparation.

D. SAE Grade G-40 or G-50 iron or steel grit.

PART 3 - EXECUTION

3.01 Surface Preparation for Ceramic Epoxy Lining

A. Deliver pipe to the lining applicator bare. Because removal of old linings may not be

possible, the intent of this specification is that the entire interior of the ductile-iron pipe or

fitting shall not have been lined with any substance prior to the application of the specified

lining material.


AECOM REBID

B. Abrasive blast the entire pipe surface to be lined per NAPF 500-03-04 (special internal

3.02 Surface Preparation for Ceramic Epoxy Joint Compound

The surface preparation shall be equal to the specifications for the project or as outlined in the

touch-up procedure. Do not apply Protecto joint compound over wet or frozen surfaces.

3.03 Lining Pipe with Ceramic Epoxy

A. After surface preparation and within eight hours, line the entire interior surface up to the

gasket groove, with the exception of the spigot end, with an average of 40 mils, 35 mils

minimum, of ceramic epoxy. If any rusting is apparent prior to lining the surface, reblast

the entire area.

B. Within eight hours of surface preparation, the interior of the pipe shall receive the specified

dry-film thickness of the ceramic epoxy. No lining shall take place when the substrate or

ambient temperature is below 40°F. The surface shall be dry and dust free. If flanged pipe

or fittings are included in the project, do not apply the lining on the faces of the flanges.

gauge. Take measurements per SSPC PA2 Section 5.1.

B. Test the coated areas of the pipe from the socket edge area of the spigot back to the bell

face for pinholes using a 2,500-volt pinhole detection test. Repair any pinholes found prior

to shipment.

3.06 Thickness Measurement at Place of Manufacture

A. Test linings per NACE SP0188-2006 with a high-voltage holiday detector set at the voltage

per NACE SP0188-2006, Table 1. If the number of holidays or pinholes is fewer than one

per 25 square feet of coating surface for internal coatings and one per 10 square feet for

external coatings, repair the holidays and pinholes by applying the coating manufacturer's

recommended patching compound to each holiday or pinhole and retest. If the number of

pinholes and holidays exceeds the above criteria, remove the entire lining and recoat the

item or pipe at the place of manufacture. Recoating will be permitted if the material has

cured less than the manufacturer's recommended cure time.

B. Measure the coating thickness on each pipe section using a coating thickness gauge

calibrated at least once per eight-hour shift. Make five separate spot measurements

(average of three readings) spaced evenly over each 100 square feet of area (or fraction


AECOM REBID

thereof) to be measured. Make three gauge readings for each spot measurement of either

the substrate or the paint. Move the probe a distance of 1 to 3 inches for each new gauge

reading. Discard any unusually high or low gauge reading that cannot be repeated

consistently. Take the average (mean) of the three gauge readings as the spot measurement.

The average of five spot measurements for each such 100-square-foot area shall not be less

than the specified thickness. No single spot measurement in any 100-square-foot area shall

be less than the specified minimum thickness. One of three readings averaged to produce

each spot measurement may under run by a greater amount. If a section of the pipe, item,

or piece of equipment does not meet these criteria, remove the entire coating and recoat the

entire item or piece of equipment.

C. Thickness determinations shall meet the following requirements:

1. No individual reading shall be below the specified minimum.

2. Individual spot readings (consisting of three-point measurements within 3 inches of

each other) shall have an average not less than the specified average thickness.

3. The average of all spot readings shall be equal to or greater than the minimum

thickness specified.

D. Thickness determinations shall be conducted using a Type 1 or 2 thickness gauge as

described in SSPC PA2 specification.

3.07 Repair of Improperly Coated Surfaces at Place of Manufacture

If the item has an insufficient film thickness and the coating material curing time has not been

exceeded, clean and topcoat the surface with the specified repair coating to obtain the specified

coverage. Sandblast or power-sand visible areas of chipped, peeled, or abraded coating,

feathering the edges. Then recoat in accordance with the specifications. Work shall be free of

runs, bridges, shiners, laps, or other imperfections.

3.08 In-Plant Inspection and Testing by Owner's Representative

A. An Owner's Representative may inspect pipe, fittings, and lining and other material during

fabrication at the mill, production plant, or shop. The Owner's Representative shall be

allowed complete and unlimited access to all parts of the work and shall be furnished with

such information and assistance as is required to make a complete and detailed inspection.

Notify the Owner at least seven days prior to beginning of material production and

application.

B. The Owner may conduct tests to determine the integrity of the lining. Pipe and fittings

shall be available onsite and accessible at least three days before installation to allow time

for the Owner's tests. If the test results indicate any manufacturing defect, the material shall

be repaired or replaced at no extra cost to the Owner. The Owner's Representative will

make a determination on whether to repair or reject defective or damaged pipe or fitting.

3.09 Manufacturer Testing and Certification

Deliver every section of pipe and fitting with certified test results of that individual pipe

section or fitting. If a pipe or fitting is not accompanied by such certifications or does not


AECOM REBID

meet the Owner-conducted tests as described above, the pipe or fitting will be rejected.

3.10 Field Repair and Touch Up

A. Repair any areas where damage has occurred due to handling using the same ceramic

epoxy prior to installation as the original lining. Apply at a film thickness of 40 mils dry.

B. Apply product only if the substrate temperature and ambient air temperature is above 45°F

and is expected not to drop below 45°F for at least two hours after application. The

substrate temperature shall be 5°F above the dew point for a period of at least two hours

after application to avoid condensation occurring on wet paint. Do not apply ceramic

epoxy over wet or frozen surfaces. Overcoat with the same material as specified above.

3.11 On-Site Storage

A. Handle pipe with belt slings and padded forks to avoid damage. Pad shipping timbers and

straps when shipping pipe and fittings.

B. The maximum delivery, storage, and installation time allowed for pipe and fitting is 120

days from the date they were lined to the date they are installed. Any pipe not meeting this

requirement will be rejected.

3.12 Handling

Handle lined pipe and fittings only from the outside of the pipe and fittings. Do not place forks,

chains, straps, hooks, etc., inside the pipe and fittings for lifting, positioning, or laying. Do not

drop the pipe or unload by rolling. Do not let the pipe strike sharp objects while swinging or

being off loaded. Do not place pipe on grade by use of hydraulic pressure from an excavator

bucket or by banging with heavy hammers.

3.13 Procedures for Sealing Cut Ends and Repairing Field-Damaged Areas of Lined Pipe and Fittings

A. Remove burrs caused by field cutting of ends or handling damage and smooth out the edge

of the lining if rough. Remove traces of oil, grease, asphalt, dust, dirt, etc.

B. Remove any damaged lining caused by field cutting operations or handling and clean any

exposed metal by sanding or scraping. Sandblasting or power tool cleaning roughening is

also acceptable. Remove any loose lining by chiseling, cutting, or scraping into well-

adhered lined area before patching. Overlap at least 1 inch of lining in the area to be

repaired.

C. With the area to be sealed or repaired clean and roughened, apply a coat of Protecto joint

compound.

D. Coat the entire freshly cut exposed metal surface of the cut pipe end. To ensure proper

sealing, overlap at least 1 inch of the lining with this repair material.
