As part of a scheme for upgrading an area of Pontefract, West Yorkshire, previously worked by the coal mining industry, Groundwork Environmental Services of Morley, Leeds, decided that this should include renovation of rusting steel fencing around part of the Mickelfield Cricket Ground. Groundwork Environmental Services, which is funded by the local authorities, approached Repair, Protection & Maintenance Ltd, the local based corrosion engineering and specialist coating contractors, to quote for the most effective renovation system.
RPM recommended the new Hi-Build coating developed by Winn & Coales, known as Denso Protal S.T. Epoxy Mastic. Although it can be spray applied, RPM considered that the extra labour in brush applying this surface tolerant coating would be offset by the savings on not taking a compressor to the Mickelfield Cricket Ground plus the advantage of not having compressor noise giving problems to nearby residents.
The fencing was wirebrushed to remove surface rust before application of two coats of the new Protal S.T. long-term protective coating to a nominal coating thickness of 400 microns.
Other benefits claimed for Winn & Coales' environmentally responsible Denso Protal S.T. Epoxy Mastic include: exceptional wetting and deep penetration of residual rust; high mechanical strength; cost saving due to fewer coats; cures at temperatures as low as 10°C. Also, its exceptional adhesion properties are designed for surfaces which have been hydrojetted or power tool prepared.
