Pharmaceutical and Hygienic Floor Coatings Aurora

Step 1, Review room classifications, cleaning, chemicals, temperatures, traffic, drains, coves, contamination controls, shutdown, and release documentation.

Step 2, Establish clean boundaries, dust extraction, ventilation, material routes, test areas, and mechanically prepared substrate.

Step 3, Repair defects and construct coves, drain details, equipment edges, joints, penetrations, and transitions.

Step 4, Mix and apply each layer under controlled temperature, humidity, dew point, coverage, pot life, and recoat windows.

Step 5, Inspect pinholes, continuity, texture, thickness, cure, colour, and detail cleanliness before facility-led release.

Hygienic flooring requires controlled construction practices and detail continuity. Harrowgate sequences preparation, repairs, cove work, body coats, and seal coats so each room has closed transitions, predictable texture, and no untreated concrete at drains, posts, curbs, or wall bases.

Room-by-room exposure review. We document disinfectants, concentrations, contact time, wash temperature, clean-in-place discharge, wheeled equipment, spill risk, static-control criteria, and whether the room is dry clean, wet clean, or aseptically controlled. This informs resin type, thickness, texture, cove height, drain treatment, and phasing.

Controlled preparation. The room is isolated from adjacent production before grinding or shot blasting. Dust extraction operates at the tool, and edges are prepared with shrouded equipment. Existing coating is removed to sound concrete. Final vacuum cleaning includes corners, ledges, penetrations, and wall bases so dust cannot drop into wet resin.

Crack, pore, and patch treatment. Dormant cracks are filled with compatible resin, pinholes and bugholes receive a scratch coat, and spalls are rebuilt without feather edges. Moving joints remain accessible and are sealed with a cleanable, chemically compatible material. Repairs are ground flush so the body coat does not preserve ledges that collect residue.

Integral coves and penetrations. We form resin or cementitious polyurethane coves at the floor-to-wall junction, including internal and external corners. Bases terminate neatly into the specified wall finish. Posts, pipes, equipment curbs, thresholds, and drain bodies receive reinforced or keyed treatment that prevents an open annular gap around the penetration.

Body coat and conductive option. Self-levelling epoxy provides a smooth controlled finish in dry rooms, while broadcast or cementitious polyurethane systems serve wet or thermal areas. Where static control is specified, conductive primer, copper grounding network, and dissipative body layer are installed as a tested assembly and connected under the electrical design.

Seal, inspect, and release. Finish coats close the aggregate, establish cleanable texture, and provide the selected gloss and colour. We inspect with strong raking light for pinholes, inclusions, missed edges, cove defects, and drain discontinuities. The room remains closed through full cure and is released through the project's cleaning and quality process.

Turnover records identify product batches, room locations, application dates, conditions, and grounding test locations where conductive flooring is part of the design. We coordinate final cleaning materials with the selected resin because aggressive scrubbing pads or unapproved chemicals can damage even a correctly installed surface. Punch work follows the same isolation and cure controls as the original placement.
