Epo-chem™ RS 500P a surface and moisture tolerant primer
Epo-chem™ RA 500M a glass flake filled epoxy
The use of underwater curing epoxies was the most practical solution for this project. In the complete refurbishment of the underside of this floating structure, some areas were replaced. Others areas required repairs to be done in-situ by using underwater curing epoxies. A team of experienced divers applied the underwater curing epoxy coating.
Chemcote’s surface tolerant Epo chem™ system is able to provide full coverage to surfaces where ideal surface preparation cannot be achieved
Condition after application of 2nd coat
Repairs were carried out at low tide where possible. Freshwater washing sections provide suitable surface preparation before applying the underwater curing epoxies.
Removal of large, flaking corroded areas and coating back to bare steel by mechanical preparation using pneumatic needle gun, air chisel, scabbling and bristle blaster
Preparation underwater to St 2 by using an underwater grinder
Primer applied to create a continuous coating without pinholes wearing gloves and application mitts.
The product was lathered on in small, workable sections and cured overnight
The next day at low tide, the repair area above the surface was washed with fresh water, then RA 500M, glass flake filled topcoat was applied to above and below water sections
By coating with Epo chem™, follow up inspections indicate the coating and repairs are still in good condition and is expected to exceed 10 years life in service
