870.2Materials

The Engineer shall approve all paint ingredients. Mix the paints in the proportions specified in this section for each kind of paint. The formulas given represent the proportions by weight of the materials to be used.

Ensure that mixed paints do not liver or curdle, and that the pigments remain in suspension to a reasonable degree satisfactory to the Engineer. 1666 1666 1666

The manufacturer shall strain paints before filling the containers. The manufacturer also shall ship paints in strong, substantial containers (according to QPL 46 and QPL 73) plainly marked with the paint name and number, color, volume, manufacturer name and address, date of manufacture, and the manufacturer’s lot number on every package. The inspection stamp on the paint container will be evidence of approval. Traffic line paint manufactured for the Department shall be delivered in 55 gallon (208 L) drums or 250 gallon (946 L) totes. The manufacturer shall stencil on the head of each drum the kind of paint, requisition number, purchase order number, and gross and net weights. Ensure that the drums are the removable head types. Ensure the totes are labeled appropriately.

Unless otherwise specified, deliver paints to the Project or the Department completely mixed and ready for use without adding oils or thinner. Use well ground paints that do not settle or badly cake in the container, and can readily be broken up to a smooth, uniform paint with good brushing consistency. When brushed or rolled on a smooth, vertical surface, the paint shall dry hard and elastic without running, streaking, sagging, or spotting. Use paint for spray application that sprays satisfactorily and does not run, sag, or streak. The first coat of paint applied in the shop or in the field to uncoated structural steel or wood is called the primer coat. The paint covering the primer coat is called the second coat, and the paint covering the second coat is called the third coat.

The formulas given in this specification represent proportions by weight.

Test methods for paint analyses shall be according to the Federal Test Methods, Standard No. 141 or the ASTM standard methods of tests for paint.

Match color visually by comparing with standard color chips obtained from the Office of Materials and Research.

Inspection and analysis will be made at the point of manufacture according to SOP 14. The manufacturer shall assist as necessary, permit the Inspector to test the ingredients before the paint is made, and witness the paint grinding. The Department reserves the right to sample and test all paint at any time before it is used.

The Department will accept a tolerance of 1 percent of the required value for the paint formulation and property requirements. EXCEPTION: This tolerance does not apply where maximum and minimum values are noted.

The following people shall furnish the Department a certificate of analysis and manufacturer’s guarantee: • The manufacturer of each brand of paint submitted for acceptance under these specifications • All Contractors proposing to use any paint specified in this Section Ensure that the certificate of analysis shows the paint trade name to be furnished, including a facsimile of the label if the paint is ready-mixed, and an analysis showing the percentage of each of the chemical elements and compounds in the pigment and vehicle. The guarantee shall assert that all paint furnished conforms to the analysis shown on the certificate filed and to the statement of percentages of ingredients shown on the labels, which are required to be on each container. The guarantee shall be sworn to by a person having authority to bind the manufacturer into an agreement. 1667 1667 1667

870.2.05 Miscellaneous Paints

Use paint for steel piling and sway bracing that meets the requirements of Subsection 870.2 and the

following:

coal tar pitch or a native pyrobitumen resin. You may use other types of material if they meet the

requirements in Table 16, below.

TABLE 16—PRIMER/FINISH COAT REQUIREMENTS

Properties Requirements

Color Black

Odor Ensure coal tar materials have no pyridine, pyridine base, or tar acid odor.

Consistency Easily applied by brush or spray to a coverage of 60 ft²/gal (1.5 m²/L), without sagging, yielding film

thicknesses of about 26 mils (0.66 mm) wet and 13 mils (0.33 mm) dry.

Drying time Apply at a rate of 60 ft²/gal (1.5 m²/L). Ensure that the material dries to a firm film within 24 hours at 70

° - 80 °F (21 °- 27 °C) and can receive a second coat.

Chemical

resistance

Ensure that the material remains intact and in good condition when immersed for 30 days in each of

the following inorganic acids, alkalies, and salts:

• 5% sulfuric acid

• 5% hydrochloric acid

• 2% phosphoric acid

• 5% sodium hydroxide

• 25% sodium chloride

• 25% calcium chloride

1) Durability: Before initially accepting a product to be supplied under this specification, the complete

system—from primer, when required, to finish coat(s)—shall be subjected to accelerated weathering

and atmospheric exposure tests according to ASTM D 822 and ASTM G 23, Type D.

2) Ensure that the system remains intact without cracking, and prevents significant steel corrosion for at

least 1,500 hours exposure in the accelerated weathering test, and 5 years atmospheric exposure in a

coastal environment.

3) The State Materials Engineer may approve systems that perform satisfactorily for up to 3,000 hours of

accelerated weathering pending completion of the 5-year atmospheric exposure tests.

4) After the Department initially accepts the material, you do not need to test each lot of material.

However, the Department will conduct other durability tests at its discretion.

by the specifications for steel-H piling, steel sway bracing, metal shells for cast-in-place concrete piling,

or prestressed concrete piling in all intermediate bents of the cap and pile trestle-type.

1) Get approval from the Laboratory for the protective coating material.

2) Use a two-component, chemically cured, coal-tar epoxy that meets the requirements of either Type I,

Class 2, Military Specification MIL-P-23236 (Ships) or U.S. Corps of Engineers Specification C-200. 168516851685

3) Ensure that the coating exhibits optimum chemical and physical resistance to alkalies and mineral

acids under continuous immersion service.

4) Ensure that the cured coating withstands considerable physical abuse such as direct impact,

abrasion, and flexing.

5) Furnish a written certification to the Engineer that the material meets the requirements of these

specifications.

Use a compound that meets the general requirements of Subsection 870.2 and Table 17.

Characteristic Requirement

Condition in the

container

No pigment component of the ready-mixed compound settles. When the package remains

unopened for one year, you can readily disperse the pigment by hand mixing.

The vehicle does not liver, curdle, or show excessive bodying.

Application The material to repair galvanizing and to galvanize welds in the field shall be such that when

applied, there is no unusual difficulty in horizontal, vertical, or overhead positions.

Adhesion Expose test panels coated according to field application specifications to weather for at least

3 months in a position 45 degrees vertical, facing south. After this time, ensure that the test

panels show no visible signs of peeling or flaking.

Gassing No build up of gas or excessive pressure in the container when stored at room temperature

for 3 months.

Dry film thickness The compound leaves a dry film between 2 - 2-1/2 mils (0.051 - 0.064 mm) thick, when

applied according to field application specifications.

Drying time The compound is set to touch in 30 minutes and is dry to recoat in 4 hours. The material is

thoroughly hard within 48 hours after application.

Hardness Dry and cure the test panels coated under these specifications for at least 48 hours.

Brush a section by hand with a wire brush. Continue brushing until you see bright metal.

Measure the dry film thickness. Accept the material if the brushing does not reduce the film

below the specified thickness.

Consistency Viscosity at 77 °F (25 °C) is 123 ± 7 Krebs units, as measured by the Stormer

Viscometer.

Weight per lb (liter) 22 ± 10% lbs (2.64 ± 10% kg) at 77 °F (25 °C).

Packaging Commercial paint packaging is acceptable for containers smaller than 1 gal (3.8 L).

For 1 gal (3.8 L) packages, use No. 26 gauge steel pails.

Do not pack more than 1 gal (3.8 L) of compound in a single container.

Storage Store the compound where the temperature stays above 45 °F (7 °C).

Use a compound that meets the requirements of Subsection 870.2, third bullet, and Table 19. 168716871687
