Paint

SPECIFICATION
Paint and Primer Coatings
This specification is for paint and primer (coating supplies) provided to NHDOT and for primer
and paint coatings utilized on equipment supplied to NHDOT.
All coating supplies and coatings utilized on equipment surfaces that are normally primed and
painted shall be suitable for severe exposure to road salt and abrasion. Coatings shall conform
to all applicable federal and state regulations and criteria pertaining to chemical and VOC
content.
Coatings containing any compound that would render the waste paint, in its dried form, a
hazardous waste per NH Code of Administrative Rules Chapter Env-Hw 400 are prohibited. This
includes RCRA listed metals (e.g., Arsenic, Barium, Cadmium, Chromium, Lead, Mercury, Silver,
Selenium) other than naturally occurring trace amounts associated with the coating pigments.
The intent of this specification is to obtain or utilize paint such that any concentration of these
metals shall not produce a TCLP test result that would fail NH DES toxicity characteristic
standards and meets the latest governing regulatory criteria.
Coatings shall not contain hexavalent chromium or cadmium. For the purposes of this
specification, a coating product "contains hexavalent chromium or cadmium" if hexavalent
chromium or cadmium was introduced as a pigment or as an agent to impart any property or
characteristic to the coating during manufacturing, distribution, or use of the applicable
coating. Coatings supplied shall not contain a total VOC content greater than 2.8 lbs/gal (340
g/l).
A written certificate of conformance to these specifications shall be submitted to NHDOT, for
coatings utilized on equipment supplied to NHDOT, indicating these compounds do not exceed
Toxicity Characteristics of NH Code of Administrative Rules Env-Hw 403.06, Table 4.9,
Regulatory Limits. Material Safety Data Sheets are not sufficient documentation of
conformance. Laboratory test results must be supplied with the written certificate. The
following test methods are incorporated by reference herein, and shall be used to test coatings.
1. American Society for Testing and Materials (ASTM) Method D3335-85a (1999), Standard
Test Method for Low Concentrations of Lead, Cadmium, and Cobalt in paint by Atomic
Absorption Spectroscopy.

2. American Society for Testing and Materials (ASTM) Method D3718-85a (1999), Standard
Test Method for Low Concentrations of Chromium in paint by Atomic Absorption
Spectroscopy.
3. EPA Test Method 1311 - TCLP Toxicity Characteristic Leaching Procedure.
4. EPA Test Methods 3010A/6010B.
5. Alternative methods which are shown to accurately determine the concentration of
hexavalent chromium or cadmium compounds in a subject coating product or its
emissions may be used upon written approval.
The coatings also shall meet the following criteria:
* Solids Content
o % By Volume 45- 60
o % By Weight 55 -70
* Recommended Dry Film Thickness 1 - 2 ml (Bulk Orders Only)
* Wet Film Thickness to Achieve 2 12 - 4 12 ml (Bulk Orders Only)
* Practical Coverage at DFT 325 - 650 sq. ft.
* Dry Time (70 - 800 F and 50% humidity)
o Tack Free 4 - 6 hours
o Handle 12 - 16 hours
o Recoat 24 hours
All bulk coating supplies shall be packaged in 1-gallon containers.
The following paints are indicative of the type of product required.
