Sign Post Paint Evaluation

Report No: 76-R7

Published in 1975

About the report:

After reviewing R. N. Robertson's report on "An Investigation of Streaking on Highway Traffic Signs", the Traffic Research Advisory Committee recommended that an evaluation of sign post paints be conducted. Special attention was to be focused on the residues formed by the sign post paints on the sign panels. The study was to select from the Department's oil base and latex paints, and four other paints supplied by the William Armstrong Smith Company, the one most feasible for use in painting sign posts. The criteria considered were chalking, durability, and appearance. After 17 months of evaluation, from February 22, 1974, to July 28, 1975, there has been some change in the retroreflective readings on the sign panels and posts. Retroreflective readings and visual observations show that the Department's number 10 oil paint chalked and deteriorated more rapidly than did the latex paints. It is recommended that the evaluation be extended to allow sufficient weathering of the sign panels and posts for a determination of the more extensive effects of paint residues on the sign panels and a more definite idea of the paint durability.
