Sandblasting Training

Lesson 1 • Types of Blasting Systems

Compares pressure, suction, and wet blasting systems by capability and use case. Helps students select the correct system for a given job.

Lesson 2 • What Is Abrasive Blasting

Defines abrasive blasting and its role in surface preparation across industries. Establishes core vocabulary used throughout the entire course.

Lesson 3 • Abrasive Media Overview

Surveys common abrasive media types and their physical properties. Links media selection to surface finish requirements introduced in later chapters.

Lesson 4 • Industry Standards and Regulations

Introduces regulatory frameworks governing abrasive blasting, including exposure limits and environmental rules. Sets compliance expectations maintained throughout the course.

Lesson 1 • Hazard Identification and Risk Assessment

Teaches systematic identification of physical, chemical, and respiratory hazards on a blast site. Forms the risk-assessment mindset applied in every subsequent chapter.

Lesson 2 • Site Safety Controls and Signage

Explains containment barriers, exclusion zones, and warning signage requirements. Proper site controls protect bystanders and ensure regulatory compliance.

Lesson 3 • Personal Protective Equipment Selection

Details PPE requirements beyond respiratory protection, including blast suits, gloves, and hearing protection. Students match PPE to specific blasting scenarios.

Lesson 4 • Respiratory Protection Systems

Covers supplied-air respirators, air-purifying respirators, and fit-testing procedures. Respiratory protection is the single most critical control in abrasive blasting.

Lesson 1 • Inspection Tools and Techniques

Introduces replica tape, digital gauges, and visual comparators used to verify blast quality. Accurate inspection prevents costly coating failures.

Lesson 2 • Understanding Surface Contamination

Identifies mill scale, rust, old coatings, and soluble salts as primary contaminants affecting coating adhesion. Contamination knowledge drives correct preparation grade selection.

Lesson 3 • Cleanliness Grade Standards

Explains white metal, near-white, commercial, and brush-off blast cleanliness grades. Students match each grade to coating system requirements.

Lesson 4 • Surface Profile and Anchor Pattern

Teaches how abrasive type and size create measurable surface profiles that promote coating adhesion. Profile measurement is a core inspection skill.

Lesson 1 • Compressor Sizing and Air Supply

Explains how to calculate required air volume and pressure for a given nozzle size and blasting rate. Correct compressor sizing prevents production loss.

Lesson 2 • Nozzle Selection and Blast Technique

Matches nozzle type, bore size, and material to production goals and surface requirements. Proper technique maximizes cleaning rate and minimizes abrasive waste.

Lesson 3 • Blast Pot Loading and Pressurization

Covers safe abrasive loading, pot pressurization sequence, and metering valve adjustment. Correct pot operation ensures consistent abrasive flow and operator safety.

Lesson 4 • Pre-Operation Inspection Checklist

Establishes a systematic pre-use inspection routine for all blasting equipment components. Catching defects before startup prevents accidents and downtime.

Lesson 1 • Dust Collection and Air Filtration

Covers dust collector types, filter ratings, and airflow calculations for blast enclosures. Effective dust collection protects workers and the surrounding environment.

Lesson 2 • Lead and Hazardous Coating Removal

Addresses enhanced controls required when removing lead-based or other hazardous coatings. These controls exceed standard blasting requirements and carry legal obligations.

Lesson 3 • Containment System Design Principles

Explains negative-pressure containment, scaffolding integration, and enclosure design for blast sites. Proper design is the foundation of environmental compliance.

Lesson 4 • Water and Runoff Management

Explains stormwater controls, secondary containment, and water treatment for wet blasting operations. Uncontrolled runoff creates regulatory violations and environmental damage.

Lesson 1 • Recyclable vs. Single-Use Abrasives

Compares recyclable steel abrasives with single-use mineral media on cost, quality, and waste volume. Students calculate cost-per-square-foot for each option.

Lesson 2 • Abrasive Recovery and Recycling Systems

Explains mechanical and vacuum recovery systems used to collect and recycle spent abrasive. Efficient recovery reduces material cost and environmental impact.

Lesson 3 • Media Selection Criteria

Defines hardness, shape, size, and density as the four key selection variables for abrasive media. Correct selection directly determines surface profile and cleanliness outcome.

Lesson 4 • Abrasive Contamination and Quality Control

Identifies how moisture, oil, and fines contaminate abrasive media and degrade blast quality. Regular testing maintains consistent surface preparation results.

Lesson 1 • Automated and Robotic Blasting Systems

Introduces centrifugal wheel blast machines, track-mounted units, and robotic blasting for high-volume applications. Automation improves consistency and reduces operator fatigue.

Lesson 2 • Blasting in Extreme Conditions

Adapts blasting procedures for high humidity, extreme temperatures, and marine or offshore environments. Environmental extremes require modified technique and additional controls.

Lesson 3 • Wet Abrasive and Vapor Blasting

Covers wet abrasive blasting setup, water-to-abrasive ratios, and inhibitor use to prevent flash rusting. Wet methods reduce dust and suit sensitive environments.

Lesson 4 • Blasting Complex Geometries

Addresses technique adjustments for corners, welds, edges, and confined spaces that standard flat-surface methods cannot address. Geometry-specific technique prevents under-blasting and coating failures.

Lesson 1 • Pre-Blast and Post-Blast Inspection

Establishes inspection steps before blasting begins and immediately after completion to verify specification compliance. Timely inspection prevents coating application over non-conforming surfaces.

Lesson 2 • Non-Conformance and Rework Management

Explains how to identify, document, and resolve non-conforming blast work efficiently. Effective rework management protects project schedules and client relationships.

Lesson 3 • Project Scheduling and Resource Planning

Covers production rate estimation, crew sizing, equipment allocation, and schedule development for blasting projects. Accurate planning prevents costly delays and resource shortfalls.

Lesson 4 • Developing a Quality Control Plan

Guides students through writing inspection hold points, acceptance criteria, and corrective action procedures. A documented quality plan is required on most commercial blasting contracts.
