The Three Coat Preventative Maintenance
The three coat preventative maintenance coating system provides excellent adhesion and anti-corrosion properties and acts as a powerful barrier against harsh weather conditions. The technology – first used to famously complete the painting of the Forth Rail Bridge in 2011 – has put glass flake epoxy based systems at the forefront of bridge painting. Sherwin-Williams glass flake epoxy coatings now feature of a number of other large bridge and highway projects, including 47 bridges across the M6 toll road, the Tay Rail Bridge and the Royal Albert Bridge.
Using glass flake technology to provide a thicker dry film in a single coat, the coatings system can be modified to meet the requirements of the customer in terms of cost effectiveness, application and finish. The selected paints typically consist of a higher build blast primer, an epoxy glass flake build coat and an acrylic urethane finish, as well as a stripe coat of epoxy glass flake.
“Frequently subject to harsh environments, including high winds and sea mists, the ongoing maintenance of bridges carries significant costs and environmental implications,” explains Nick Ball, marketing director EMEA at Sherwin-Williams Protective & Marine Coatings. “By transferring our innovative coatings technologies across markets, we have reduced the need for service and maintenance and extended asset life within the bridge and highways sector. This delivers a number of benefits to customers in terms of labour costs, energy usage and volumes of paint required. In addition, the higher volume solids used in the coatings system mean that fewer volatile organic compounds (VOCs) are emitted into the atmosphere.”
