3501Basic Requirements for Paints

3501.1SCOPE

Provide paints for construction and maintenance.

3501.2REQUIREMENTS

A Package Stability Ensure the paint does not cake, liver, thicken, curdle, gel, or show other objectionable properties that cannot be corrected by stirring during 6 months after delivery.

B Colors Provide paint matching the AMS-STD-595A colors or the Department’s standard colors required by the Contract. The Department’s standard colors are located at the Materials Laboratory . A paint color is considered to match the specified Standard if ∆ E ≤ 3.0 when measured according to ASTM D2244, Standard Practice for Calculation of Color Tolerances and Color Differences from Instrumentally Measured Color Coordinates, using the following conditions:

C Toxic Metals and Volatile Organic Compounds (VOC) Provide paints free of toxic metals and meeting the requirements of Federal and MPCA VOC regulations. D Manufacturing and Packaging Screen paint while filling containers to remove coarse particles and skins. Package the paint in new containers marked with the following information:

Provide paint in quantities based on the volume or unit mass at 77 °F. E Drying Time Ensure drying time for paint meets the requirements of the Contract. F Approval Process Obtain approval of the paint from the Engineer before use, unless the C ontract requires the paint selection or it appears on the APL.

3501.3SAMPLING AND TESTING

Provide samples at rates and sizes meeting the requirements of the Schedule of Materials Control or as required by the Contract. Provide a color draw down sample on a Leneta chart per ASTM D2805, Standard Test Method for Hiding Power of Paints by Reflectometry, (Sections 6.1.2 for paper chart description and 7.7.1 for film application) to the Materials Laboratory for verification of the finish coat color.
