Working in collaboration with JN Bentley, SPG successfully demonstrated the benefits of implementing a more efficient process of coating removal, surface preparation and coating application using a system that can be applied outside of the normal ambient parameters.  As a result of the demonstration of efficiency the Environment Agency awarded a package of work utilising the new procedure.  Third party inspection was implemented, and all participating parties worked to monitor and measure the effect of the process on programme, quality, cost and most importantly risk.

The EA traditionally utilised abrasive blast cleaning when refurbishing its large portfolio of steel structures.  The risks associated with this process of coating removal and surface preparation include contamination of the land or watercourse, creation of large amounts of hazardous waste, exposure of operatives to hazardous substances, particularly lead, reduced annual output due to costs, standing time costs due to plant rental in times of inclement weather.

Specialist Painting Group introduced the EA to the use of RPR heat induction as a means of safely removing the existing coating system prior to mechanical preparation coupled with the application of a coating system that requires ambient humidity as the catalyst for the curing mechanism.  This process has previously been successfully integrated into the procedures for other large end users such as EDF, Network Rail, PepsiCo and Natural Resources Wales.

Key Benefits:

  • Increased number of refurbishments being carried out annually
  • 40% reduction in project cost
  • 99% reduction in hazardous waste
  • 50% reduction in project duration
