Covers screw guns, routers, mixing drills, and lifts used in drywall and plaster work. Students operate each tool safely and identify when mechanical assistance is required.
Lesson 4 • Hand Tools for Plaster and Drywall
Identifies and demonstrates proper use of trowels, hawks, knives, and measuring tools. Correct tool selection directly affects finish quality and work efficiency.
Lesson 5 • Plaster Materials and Mixes
Covers gypsum, lime, and cement-based plasters along with aggregates and additives. Students understand how mix ratios affect workability, set time, and finish quality.
Chapter 3HideHide detailsSee detailsReading Plans and Layout Fundamentals
Reading Plans and Layout Fundamentals
Lesson 1 • Layout for Plaster Systems
Covers scratch coat grid planning, control joint placement, and lath layout on curved or irregular surfaces. Builds on flat-surface layout skills introduced earlier.
Lesson 2 • Measurement and Marking Techniques
Teaches accurate linear and diagonal measurement, squaring rooms, and marking stud lines. Precision at this stage prevents costly errors during installation.
Lesson 3 • Layout for Drywall Installation
Applies measurement skills to plan panel placement, minimize waste, and locate seams away from stress points. Students produce a panel layout diagram for a sample room.
Lesson 4 • Framing Inspection for Finishers
Covers how to evaluate framing alignment, spacing, and moisture content before applying board or plaster. Identifies framing defects that must be corrected first.
Lesson 5 • Construction Drawing Basics
Introduces floor plans, elevations, and detail drawings relevant to interior finishing. Students interpret symbols and dimensions before any layout work begins.
Chapter 4HideHide detailsSee detailsDrywall Installation Techniques
Drywall Installation Techniques
Lesson 1 • Corner and Edge Treatments
Teaches installation of metal and vinyl bead at outside corners, inside corners, and archways. Proper bead placement is essential for clean, durable finished edges.
Lesson 2 • Hanging Drywall on Walls
Covers panel sequencing, fastener patterns, and butt-joint management on vertical surfaces. Students hang a full wall section meeting industry fastener spacing standards.
Lesson 3 • Cutting and Shaping Drywall Panels
Teaches score-and-snap, router, and jab-saw cutting for straight and curved cuts. Accurate cutting reduces waste and ensures tight fits at openings and corners.
Lesson 4 • Fire-Rated and Specialty Assemblies
Covers multi-layer board installation, shaft-wall systems, and penetration sealing for fire-rated assemblies. Students apply manufacturer and code-compliant installation sequences.
Lesson 5 • Ceiling Drywall Installation
Addresses the added complexity of overhead work, including panel support, fastener scheduling, and sag prevention. Builds directly on wall-hanging skills with added safety considerations.
Chapter 5HideHide detailsSee detailsTaping, Mudding, and Finishing Drywall
Taping, Mudding, and Finishing Drywall
Lesson 1 • Fill and Finish Coat Application
Covers second and third coat application with progressively wider knife strokes to blend seams. Students achieve smooth, flat surfaces ready for sanding.
Lesson 2 • Joint Compound Types and Selection
Distinguishes setting-type from drying-type compounds and identifies the correct product for each coat. Compound selection directly affects adhesion, shrinkage, and sanding ease.
Lesson 3 • Sanding and Surface Preparation
Teaches hand and pole sanding sequences, dust control, and surface inspection under raking light. Proper sanding determines final paint adhesion and visual quality.
Lesson 4 • Tape Embedding and First Coat
Teaches paper and mesh tape application over flat seams, inside corners, and bead. A properly embedded tape coat prevents bubbles, lifting, and cracking in subsequent coats.
Lesson 5 • Finish Levels and Quality Standards
Introduces the industry finish level system from Level 0 through Level 5 and the conditions requiring each. Students self-assess completed work against defined quality benchmarks.
Chapter 6HideHide detailsSee detailsTraditional and Modern Plaster Systems
Traditional and Modern Plaster Systems
