Paint Inspector Course

Lesson 1 • Coating Chemistry Basics

Introduces binders, pigments, solvents, and additives as the four core components of paint. Establishes chemical vocabulary used throughout the course.

Lesson 2 • Industry Standards and Terminology

Defines key inspection terms and introduces major standards bodies governing coatings work. Provides the regulatory vocabulary inspectors use daily.

Lesson 3 • Coating Types and Categories

Covers solvent-borne, water-borne, powder, and high-solids coatings. Connects coating selection to substrate and service environment.

Lesson 1 • Power and Hand Tool Cleaning

Addresses mechanical cleaning methods for areas where blasting is impractical. Defines achievable cleanliness levels and their limitations.

Lesson 2 • Importance of Surface Preparation

Establishes why surface condition is the single greatest factor in coating performance. Connects inadequate preparation to common coating failures.

Lesson 3 • Abrasive Blast Cleaning Methods

Covers open-wheel blast, pressure blast, and vacuum blast techniques and their cleanliness grades. Students match blast method to project specification.

Lesson 4 • Chemical and Water Cleaning

Covers solvent cleaning, detergent washing, and high-pressure water jetting for contaminant removal. Links each method to specific contaminant types.

Lesson 1 • Dew Point Calculations

Teaches manual and chart-based dew point determination from wet-bulb and dry-bulb readings. Students apply the 3°C/5°F safety margin rule.

Lesson 2 • Key Environmental Parameters

Identifies air temperature, substrate temperature, relative humidity, and dew point as critical variables. Explains how each parameter influences coating behavior.

Lesson 3 • Environmental Documentation

Establishes procedures for recording environmental readings at required intervals during application. Connects documentation to project quality records.

Lesson 1 • Stripe Coating and Edge Treatment

Explains why edges, welds, and bolts require additional coating passes before full application. Students verify stripe coat coverage during inspection.

Lesson 2 • Application Defects Identification

Catalogs runs, sags, dry spray, pinholes, and holidays as common application defects. Students trace each defect to its root cause.

Lesson 3 • Brush and Roller Application

Addresses brush and roller techniques for stripe coats, touch-up, and confined areas. Identifies coverage limitations and common technique errors.

Lesson 4 • Spray Application Equipment

Covers airless, conventional air, and plural-component spray systems and their operating principles. Students match equipment type to coating viscosity and project scale.

Lesson 1 • Wheel Gauge Application

Covers the rotating eccentric wheel gauge for continuous wet film measurement on flat surfaces. Students compare results with comb gauge readings.

Lesson 2 • Comb Gauge Technique

Teaches correct placement, reading, and recording of notched comb gauges on freshly applied coatings. Students practice on representative surfaces.

Lesson 3 • Wet Film Thickness Concepts

Explains the relationship between wet film thickness, volume solids, and expected dry film thickness. Establishes why wet measurement enables early correction.

Lesson 1 • Measurement Procedures and Patterns

Teaches area-based measurement patterns, number of readings per area, and probe placement technique. Students apply statistical sampling rules from specifications.

Lesson 2 • Ultrasonic DFT on Non-Metal Substrates

Introduces ultrasonic pulse-echo gauges for measuring coatings on concrete and wood substrates. Students calibrate and interpret readings on non-metallic surfaces.

Lesson 3 • Gauge Calibration and Verification

Covers zero adjustment, certified shim verification, and substrate correction procedures. Students perform calibration sequences before each measurement session.

Lesson 4 • DFT Measurement Principles

Explains magnetic pull-off, magnetic induction, and eddy-current operating principles for ferrous and non-ferrous substrates. Establishes gauge selection logic.

Lesson 1 • Holiday Detection Fundamentals

Defines holidays, pinholes, and voids as coating discontinuities that compromise corrosion protection. Explains the electrical detection principle.

Lesson 2 • Holiday Marking and Repair Verification

Establishes procedures for marking, mapping, and verifying repair of detected holidays. Students confirm repaired areas pass re-test before sign-off.

Lesson 3 • High-Voltage Spark Testing

Addresses DC and AC spark tester operation, voltage calculation, and electrode selection for thick coatings. Students calculate test voltage from DFT.

Lesson 1 • Final Inspection Package Assembly

Guides compilation of all inspection records into a complete project quality dossier. Students verify completeness against a checklist before submission.

Lesson 2 • Non-Conformance Reporting

Covers identification, classification, and formal documentation of specification deviations. Students write non-conformance reports that support corrective action.

Lesson 3 • Photographic Documentation

Establishes standards for capturing, labeling, and filing inspection photographs as objective evidence. Students practice photo documentation of defects and conditions.

Lesson 4 • Inspection Report Structure

Defines the required elements of a daily inspection report including project data, readings, and observations. Students draft reports that meet client and specification requirements.
