    Introduces the full range of hand tools, power tools, and application equipment used commercially. Students match tools to specific job requirements.

  • Lesson 5 • The Commercial Painting Trade

    Defines commercial painting and distinguishes it from residential work. Establishes the professional context for all subsequent technical training.

Chapter 2See details

Surface Preparation Techniques

  • Lesson 1 • Repairing Defects and Damage

    Teaches patching, filling, and levelling damaged surfaces to achieve a uniform substrate. Repair quality directly affects the final painted appearance.

  • Lesson 2 • Abrasive and Mechanical Preparation

    Introduces sanding, grinding, and abrasive blasting to create proper surface profiles. Mechanical prep ensures mechanical adhesion of primers and coatings.

  • Lesson 3 • Cleaning and Degreasing Methods

    Covers mechanical and chemical cleaning to remove contaminants before coating. Clean surfaces are prerequisite to all subsequent prep steps.

  • Lesson 4 • Understanding Substrate Types

    Identifies concrete, masonry, drywall, wood, and metal substrates common in commercial buildings. Each substrate demands a specific preparation approach.

  • Lesson 5 • Masking and Site Protection

    Covers protecting adjacent surfaces, fixtures, and furnishings before painting begins. Effective masking reduces rework and maintains client property.

Chapter 3See details

Primers and Coating Chemistry

  • Lesson 1 • Topcoat Categories and Sheens

    Covers flat, eggshell, satin, semi-gloss, and gloss finishes and their commercial applications. Sheen selection balances aesthetics with durability and cleanability.

  • Lesson 2 • Reading and Applying Product Data Sheets

    Teaches extraction of critical application data from manufacturer technical documents. Compliance with product data sheets ensures warranty validity and system performance.

  • Lesson 3 • Primer Types and Functions

    Distinguishes oil-based, latex, epoxy, and specialty primers by function and substrate compatibility. Correct primer selection is critical to system performance.

  • Lesson 4 • Specialty Coatings for Commercial Use

    Introduces epoxy, urethane, intumescent, and antimicrobial coatings used in demanding commercial environments. Specialty coatings address performance requirements beyond standard paint.

  • Lesson 5 • Paint Chemistry Essentials

    Explains binders, pigments, solvents, and additives that compose commercial coatings. Understanding chemistry enables informed product selection and troubleshooting.

Chapter 4See details

Brush and Roller Application

  • Lesson 1 • Brush Selection and Loading

    Matches brush type, bristle material, and size to coating and substrate. Proper loading technique prevents drips and ensures even paint distribution.

  • Lesson 2 • Rolling Large Commercial Surfaces

    Applies systematic rolling patterns to walls, ceilings, and floors in commercial spaces. Consistent technique eliminates lap marks and achieves uniform film thickness.

  • Lesson 3 • Roller Selection and Setup

    Covers nap thickness, core material, and frame selection for commercial rollers. Correct roller setup directly affects texture, coverage, and application speed.

  • Lesson 4 • Cutting In and Edging

    Teaches precise brush application along edges, corners, and trim lines. Clean cut-in lines define quality on commercial interiors and storefronts.

  • Lesson 5 • Quality Control for Brush and Roller Work

    Identifies and corrects common defects such as holidays, sags, and lap marks. Systematic inspection ensures client-ready results before project sign-off.

Chapter 5See details

Spray Application Systems

  • Lesson 1 • Overspray Control and Containment

    Addresses masking, wind management, and containment strategies to protect non-target surfaces. Overspray control is a legal and contractual obligation on commercial sites.

  • Lesson 2 • Spray Equipment Types and Components

    Compares airless, HVLP, and air-assisted airless systems by output, transfer efficiency, and use case. Equipment knowledge is the foundation of safe and productive spray work.

  • Lesson 3 • Spray Equipment Cleaning and Maintenance

    Details flushing, tip cleaning, and preventive maintenance routines for spray systems. Proper maintenance extends equipment life and prevents mid-job failures.

  • Lesson 4 • Equipment Setup and Calibration

    Covers pressure settings, tip selection, and fan pattern adjustment for different coatings. Correct calibration prevents overspray waste and surface defects.

  • Lesson 5 • Spray Technique and Body Mechanics

    Teaches gun distance, speed, overlap, and trigger control for uniform film build. Consistent technique is the difference between professional and amateur spray results.

Chapter 6See details

Exterior Commercial Painting

  • Lesson 1 • Elevated Access Equipment

    Trains safe use of scaffolding, boom lifts, and swing stages for multi-storey exteriors. Access equipment competency is mandatory for commercial exterior work.

  • Lesson 2 • Exterior Substrate Assessment

    Evaluates condition of stucco, brick, EIFS, metal panels, and wood on commercial exteriors. Accurate assessment drives correct prep and product selection decisions.

  • Lesson 3 • Waterproofing and Sealant Systems

    Introduces elastomeric coatings, penetrating sealers, and joint sealants for exterior moisture control. Waterproofing extends building envelope life and reduces maintenance costs.

  • Lesson 4 • Exterior Coating Application Methods

    Applies brush, roller, and spray techniques to large exterior facades and architectural features. Method selection balances speed, quality, and overspray risk on active sites.

  • Lesson 5 • Weather and Environmental Conditions

    Covers temperature, humidity, dew point, and wind thresholds for exterior coating application. Environmental compliance protects coating integrity and warranty coverage.

Chapter 7See details
