AMPP Bridge Coatings study plan

Identify and rank rust and mill-scale grades using visual reference criteria, from fully rusted through blast-cleaned surfaces.

Compare abrasive blasting media and specify the surface profile range each produces on steel.

Translate cleanliness and profile requirements into pass/fail field criteria an inspector can apply without ambiguity.

Explain how substrate defects - laminations, weld spatter, sharp edges, soluble salts, and residual coatings - degrade coating performance.

Differentiate abrasive blasting, power-tool cleaning, water jetting, and hand cleaning by achievable cleanliness, profile, and production rate.

Select appropriate preparation methods for concrete, galvanized, and previously coated bridge substrates.

Outline the building blocks of a coating system - primer, intermediate, and topcoat - and state the function of each.

Connect surface preparation quality to adhesion and long-term performance by tracing common failure mechanisms back to preparation faults.

Classify binder chemistries - epoxy, polyurethane, polysiloxane, zinc-rich, and alkyd - by cure mechanism, strengths, and service limitations.

Calculate volume solids, wet film thickness, dry film thickness, and theoretical coverage for a given coating and area.

Match candidate coating systems to bridge exposure zones: atmospheric, splash, immersion, and buried.

Interpret a specification for DFT per coat, recoat windows, stripe coat requirements, and VOC limits.

Explain airless spray, conventional spray, brush, and roller application and the defects characteristic of each.

Identify environmental limits that govern application: ambient temperature, steel temperature, dew point spread, relative humidity, and wind.

Describe recoat windows and explain the consequences of exceeding them.

Summarize specification requirements that link material selection to application method.

Calculate dew point and steel temperature margin from given psychrometric data and determine go/no-go for application.

Sequence a bridge coating job from preparation through stripe coat, primer, intermediate, and topcoat, naming the hold points at each stage.

Diagnose common application defects - sagging, orange peel, dry spray, pinholing, and mud cracking - and trace each to its root cause.

Apply stripe coating and edge-retention requirements to difficult geometries such as welds, bolts, and cut edges.

Select and properly use DFT gauges, holiday detectors, and adhesion test methods, including calibration and measurement-count rules.

Apply visual standards and acceptance criteria to both surface preparation and finished coating appearance.

Design inspection stages and hold points spanning preparation, application, cure, and final acceptance.

Interpret test data - chloride and salt contamination, cure checks, and adhesion results - against specification limits.

Evaluate QA/QC records - daily reports, batch and lot records, calibration logs, and nonconformance reports - for completeness and traceability.

Identify the principal hazards of abrasive blasting and coating application and select controls using the hierarchy of controls.

Summarize regulatory requirements governing VOC content, lead-based paint disturbance, containment, and waste disposal.

Distinguish the roles and responsibilities of inspector, applicator, and owner across a coating project.

Complete a full-length 100-question mock exam under timed conditions spanning all five domains.

Analyze missed items by domain and re-study the two weakest areas until each reaches 80%.

Recite documentation and recordkeeping requirements needed for project closeout and turnover.

Verify that safety, regulatory, and documentation content is recalled at the same level as technical coating content.
