Industrial Grade Epoxy Floor Coating: Water Treatment Facility, UK

20th May 2025

Industry: Water Treatment
Location: United Kingdom
Application: Industrial Grade Epoxy Floor Coating
Products: 503 SPEP, 507 DWPU & 571 Concrete Repair LW

The Challenge

In critical areas of a UK water treatment site, plant room floor required industrial grade epoxy floor coating protection urgently due to repeated exposure to high strength sodium hypochlorite (NaOCl). The existing ceramic tiled surface, already coated several times previously, had begun to fail. Spills were leading to chemical attack, deterioration of grout lines, and progressive loss of surface integrity.

A long term solution was needed to protect the floors against further damage, one that could be applied without removing the existing tiles, would tolerate chemical exposure, and offer easy maintenance over time.

The Solution

The industrial grade epoxy floor coating protection started with mechanically abraded using a floor planer to remove failed coatings and roughen the surface. Damaged grout and missing tiles were repaired with 571 Concrete Repair LW to create a suitable base for the new coating system.

A primer coat of 503 SPEP was applied at 150–200 microns and allowed to cure overnight. Two coats of 507 DWPU were then applied in contrasting colours at 300–400 microns each, forming a seamless protective layer. The two colour coating system also enabled easy identification of wear areas during inspections, supporting proactive maintenance planning. The solvent free formulation ensured safe application with minimal disruption to surrounding plant operations.
