Inspection

Inspector Detail

Common issues

  • Under-cure or overcoat interval exceedance leading to intercoat adhesion failure
  • Application at incorrect film thickness - too thin leaves inadequate protection, too thick risks cracking or solvent entrapment
  • Poor surface preparation (insufficient blast profile or cleanliness) causing early coating breakdown
  • Application outside the specified temperature/humidity window causing blushing or poor cure
  • Flash rusting between blasting and priming if the interval is too long in humid conditions

Inspection checklist

  • Check dry film thickness (DFT) against the specified range using a calibrated gauge
  • Verify the surface preparation standard achieved before application was recorded
  • Confirm the overcoat interval was respected between coats, or that the surface was reactivated if exceeded
  • Check for holidays/pinholes using an appropriate detection method for immersed or critical areas
  • Visual inspection for cracking, blistering, or delamination on in-service surfaces
  • Confirm application conditions (steel temperature, dew point margin, humidity) were within the product data sheet limits at time of application

Service intervals

DFT verification during applicationcontinuous during application, recorded per coat
Coating condition survey of in-service structureannually as part of a general structural/coating condition assessment, or per the vessel's coating maintenance programme

Typical wear limits

Dry film thicknessapply and maintain within the product data sheet's stated DFT range - values significantly below nominal reduce corrosion protection life, values significantly above increase cracking risk

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Base and curing agent components, correct batch-matched pair for the same product line
  • Compatible thinner as specified on the product data sheet
  • Spray tip/filter consumables for the application equipment

Safety

  • Epoxy components and solvents are flammable - ensure ventilation and ignition source control during application
  • Epoxy hardener components can cause skin and respiratory sensitisation - use the PPE and respiratory protection specified on the safety data sheet
  • Confined space precautions apply when spraying inside tanks or enclosed compartments (ventilation, gas-free certificate, standby)

Class survey

Structural/coating surveys (e.g. under the Performance Standard for Protective Coatings where applicable to the space) check DFT records, surface preparation records, and visual condition (rust grade, breakdown percentage) rather than the product itself - keep application records (batch numbers, DFT logs, conditions) available for survey.

Estimated lifetime: As a coating system rather than machinery, service life is measured in years, not hours; a properly applied epoxy primer/topcoat system in a marine environment is commonly expected to perform for 5-10+ years before major touch-up or recoating is needed, depending on exposure and maintenance

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
