The client was looking to protect their new concrete bund with a coating system which had suitable chemical resistance after the previous concrete bund had been severely eroded by the acidic cleaning product stored within it.
There could be no disruption to the normal operating processes of the petrochemical plant. Therefore grit blasting and the use of solvent-based paints were not permissible.
The surfaces were mechanically prepared by vacuum controlled diamond grinding to remove surface laitance and contamination. The surface was then primed with one coat of solvent-free concrete primer Damp-crete™ RH 800.
All blow holes in the concrete were filled with a twin component polyester filler to ensure a seamless finish. This was followed by two coats of solvent-free, glassflake epoxy Epo-chem™ RW 500.
The project was successfully completed without disruption the working plant; which allowed significant time and cost savings to be achieved.
The following is a list of the time and cost saving benefits the client achieved by utilising this unique solution:
- Solvent-free solution
- No grit blasting
- No disruption to working petrochemical plant
- Exceptional chemical resistance
- Significantly reduced H&S and Fire Hazards
