6-07.3(4) Paint System Manufacturer’s Technical Representative

The paint system manufacturer’s technical representative shall be present at the jobsite
for the pre-painting conference and for the first day of paint application, and shall
be available to the Contractor and Contracting Agency for consultation for the full
project duration.

6-07.3(5) Pre-Painting Conference

A pre-painting conference shall be held 5 to 10 working days before beginning painting
operations to discuss the painting plan, construction operations, personnel, and
equipment to be used. Those attending shall include:
1. (Representing the Contractor) The superintendent, on-site supervisors, and all crew

members in charge of cleaning and preparing the surfaces, containing, collecting
and disposing of all removed materials, applying the paint, and performing all quality
control inspections, measurements and tests; and the paint system manufacturer’s
technical representative; and

2. (Representing the Contracting Agency) The Engineer, key inspection assistants, and

representatives of the WSDOT HQ Construction Office.

If the Contractor’s key personnel change between any work operations, an additional
conference shall be held if requested by the Engineer.

For projects that include painting of multiple structures, a separate conference may be
held for each structure, at the discretion of the Engineer.

6-07.3(6) Paint Containers, Storage, and Handling

6-07.3(6)A

Paint Containers

Paint container labels shall include the following information:
1. Manufacturer’s name and product name, with batch number and date of

manufacture.

2.  Color name and SAE AMS Standard 595 color number, where applicable.
3.  Shelf life of the product, from date of batch manufacture.
4.  Storage requirements and temperature limits.

Paint containers shall conform to U.S. DOT hazardous material shipping regulations. Paint
shall be delivered to the jobsite in the manufacturer’s original unopened containers with
the original manufacturer’s label legible and intact. Paint will be rejected if the container
has a puncture or if the lid shows signs of paint leakage. Each container shall be filled with
paint and sealed airtight. Each container shall be filled with the amount of paint required
to yield the specified quantity when measured at 70°F. All paint shall be shipped in new
suitable containers having a capacity not greater than 5 gallons.

6-07.3(6)B

Paint Storage

Paint materials shall not be used or stored on-site after the shelf life expiration date.

Paint material shipping, handling, and storage shall conform to Sections

1-06.4

and

9-08.1(4)

and the following requirements:

1. Paint materials shall be stored in the manufacturer’s original containers in a weather-

tight space where the temperature is maintained within the storage temperature
range recommended by the paint manufacturer, but in no case where the
temperature is lower than 40°F or greater than 100°F.

2. The Contractor shall monitor and document daily the paint material storage facility

with a high-low recording thermometer device.

3. The paint material storage facility shall be separate from the storage facilities

used for storing painting equipment and used for storing containment waste and
construction-generated waste.

6-07.3(7) Paint Sampling and Testing

The Contractor shall provide the Engineer 1 quart of each paint representing each lot.
Samples shall be accompanied with a Safety Data Sheet.

If the quantity of paint required for each component of the paint system for the entire
project is 20 gallons or less, then the paint system components will be accepted as
specified in

Section 9-08.1(7)

Sampling and testing performed by the Contracting Agency shall not be construed as
determining or predicting the performance or compatibility of the individual paint or the
completed paint system.

6-07.3(8) Equipment

6-07.3(8)A

Paint Film Thickness Measurement Gages

Paint dry film thickness measurements shall be performed with either a Type 1 pull-off
gage or a Type 2 electronic gage as specified in SSPC Paint Application Specification No.
2, Procedure for Determining Conformance to Dry Coating Thickness Requirements.

Paint wet film thickness measurement gages shall be stainless steel with notches
graduated in 1-mil increments.

6-07.3(9) Painting New Steel Structures

All materials classified as nongalvanized structural steel shall be painted with a four-coat
paint system as specified in

Section 6-07.3(9)A

. The primer coat shall be shop-applied.

The intermediate, intermediate stripe, and top coats shall be field-applied after erection
and following any primer coating repair operations.

Steel surfaces embedded in concrete, and faying (contact) surfaces of bolted connections
(including all surfaces internal to the connection and all filler plates) shall receive the
primer coat only. Stainless steel surfaces are not required to be painted. Welded shear
connectors are not required to be painted.

Temporary attachments or supports for scaffolding, containment or forms shall not
damage the paint system.

6-07.3(9)A

Paint System
