Pennsylvania DOT-Interstate 476

Products used: Polagard AG

This freeway was scheduled to open in 1990. Soundwalls and bridges needed to be coated for protection against graffiti. The product to be used needed to set fast, allowing maximum early protection, and needed to provide protection for 5 to 10 years.
2.3 million square feet of surfaces were coated with Polagard AG between Exit 3 and Exit 7, and the freeway opened on schedule. Aggregate finished soundwall was coated with clear Polagard AG.  Bridges, grapestake finish concrete, and sectional foundations were coated with custom colors of Polagard AG.  After 15 years, the Polagard AG is still performing adequately, has retained its gloss level within ten degrees, and its color within 2∆E.
