The management for Shanghai’s pump stations was searching for an attractive and cleanable floor finish to use on the walking surfaces at its facilities. Tnemec's distributor presented a coating system featuring Series 224 Deco-Fleck, a decorative flake polyamine epoxy floor topping, as a solution to the facility’s flooring needs.
Test patches were used to determine if the system met all of the owner’s requirements for moisture resistance, resistance to sanitizing solutions, skid-resistance and general aesthetic quality. All tests met the owner’s requirements and use of the coating system was approved. The system was then applied at the Pudong Waigaoqiao No. 3 pump station.
Prior to coating, the floors were prepared in accordance with SSPC-SP13/NACE No. 6 Surface Preparation of Concrete to achieve a CSP 3 surface profile. After preparation, the concrete was primed with Series N69 Hi-Build Epoxoline II, a polyamidoamine epoxy. After priming, a complete Deco-Fleck system was installed. A finish coat of Series 284 Deco-Clear, a clear polyamine epoxy was then applied to complete the floors.
The owner was so pleased with the appearance and durability of the floor of the No. 3 pump station that the Deco-Fleck coating system is now the standard flooring design for all 130 pump stations in Pudong.
