Tropical Anti-Fungal Floor Coatings in FNQ Warehouses Often Contain QAC Compounds That Affect Epoxy Adhesion

Cairns and Far North Queensland's high-humidity, high-temperature environment makes mould growth on industrial floors a genuine operational problem. A Portsmith warehouse had been treated with a commercial anti-fungal floor coating several years prior to our marking visit — the type specifically formulated for tropical FNQ conditions where standard floor coatings get surface mould without biocide additives.

The anti-fungal additive in the coating was a quaternary ammonium compound — the same biocide chemistry used in food processing sanitisers. QAC leaves a surface film that reduces surface energy and can interfere with epoxy primer adhesion. We didn't identify the coating type during assessment — it looked like a standard aged concrete sealer.

Primer adhesion in the treated zones was patchy. Pull-off tests at 0.9-1.1 MPa rather than the expected 1.6-2.0 MPa. The phosphoric acid etch wash we use for QAC-contaminated food processing floors worked here too — it neutralised the QAC residue and restored adhesion to acceptable levels after a re-test.

Portsmith is Cairns' primary industrial precinct — Aumuller Street, Hartley Street, the QR freight terminal, and the marine and logistics businesses at the southern end of the city. TMR approved. Anti-fungal floor coating identification is now standard on every Portsmith warehouse floor assessment — FNQ warehouses use tropical-grade products that don't always appear on the standard coating checklist.

Frequently Asked Questions

Yes. Portsmith Cairns industrial precinct warehouses are part of our regional QLD schedule. Anti-fungal floor coating QAC assessment on every FNQ warehouse floor visit. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Portsmith quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For Workplace Health and Safety QLD improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion comes with photo documentation, a compliance statement, and material specifications. TMR approved for any road or carpark marking that requires local council or state road authority sign-off.

Cairns averages over 2,000mm of rainfall annually and experiences high year-round humidity. Uncoated or poorly sealed concrete floors in warehouses regularly develop surface mould and mildew in these conditions. Anti-fungal coatings incorporating QAC biocides are a standard FNQ industrial floor treatment to manage this. Surface preparation is assessed before every Portsmith warehouse job, not assumed. That means checking moisture content, surface pH, contamination, and existing coating compatibility before a product is specified. We've completed 5,000+ warehouse and industrial floor marking jobs since 2009, and we carry $20M public liability insurance. Completion documentation includes product data sheets, application records, and compliance certification.

Ask the facility manager for the floor coating product name or specification. The product data sheet will list the biocide additives. If the coating records aren't available, the acetone rub test identifies QAC surface residue — QAC films dissolve partially in acetone and show colour transfer on a cotton bud rub, similar to chlorinated rubber identification.

Yes — the mechanism is identical. Dilute phosphoric acid (10-15%) applied, scrubbed in, and rinsed thoroughly neutralises the QAC surface film regardless of how it was applied.
