Wood Finishing Course

Lesson 1 • Essential Tools and Equipment

Surveys brushes, pads, spray guns, and mixing tools used throughout the course. Proper tool selection prevents application defects before work begins.

Lesson 2 • Wood Anatomy and Surface Behaviour

Covers grain structure, porosity, and how wood movement affects finish adhesion. Establishes the biological basis for every surface preparation decision in the course.

Lesson 3 • Finish Selection Decision Framework

Teaches a systematic method for matching finish type to project requirements. Students practice selecting finishes based on durability, appearance, and substrate needs.

Lesson 4 • Finish Chemistry Fundamentals

Explains solvent-based, water-based, and oil-based finish chemistry. Students gain the vocabulary needed to read product labels and safety data sheets accurately.

Lesson 1 • Scraping and Planing Surfaces

Introduces card scrapers and hand planes as alternatives to sandpaper. Scraped surfaces accept stain more evenly than sanded surfaces on many species.

Lesson 2 • Repairing Defects Before Finishing

Covers putty, epoxy filler, and burn-in techniques for holes, dents, and cracks. Defect repair completed before finishing prevents visible flaws in the final surface.

Lesson 3 • Cleaning and Degreasing Wood

Explains how oils, waxes, and mill glaze contaminate surfaces and how to remove them. Clean surfaces ensure consistent finish adhesion across the entire workpiece.

Lesson 4 • Grain Filling and Pore Preparation

Teaches paste wood fillers and sanding sealers for open-grain species. Filled pores create a level foundation for high-gloss topcoats.

Lesson 1 • Stain Types and Chemistry

Distinguishes pigment stains, dye stains, and gel stains by particle size and penetration. Understanding chemistry guides product selection for each species and effect.

Lesson 2 • Blotch Control and Conditioners

Addresses blotch-prone species like pine and cherry using pre-conditioners and washcoats. Controlled penetration produces uniform colour on difficult substrates.

Lesson 3 • Colour Matching and Consistency

Covers spectrophotometer use, sample boards, and batch mixing for colour consistency. Repeatable colour is essential for production work and furniture repair.

Lesson 4 • Toners and Glazes for Colour Depth

Introduces toners sprayed over sealer coats and glazes wiped into profiles. Layered colour techniques add depth and visual complexity to finished pieces.

Lesson 1 • Inter-coat Sanding and Rubbing Out

Teaches 320-grit and finer inter-coat sanding and final rubbing-out with abrasive compounds. Rubbing out transforms a good finish into a flawless one.

Lesson 2 • Pad and Cloth Application

Covers wiping varnish, Danish oil, and hardwax oil applied with pads or cloths. Pad application suits thin-film finishes and field touch-up work.

Lesson 3 • Brushing Technique for Flat Surfaces

Teaches wet-edge maintenance, tipping off, and stroke sequencing on panels. Consistent stroke technique prevents laps, sags, and brush marks on large surfaces.

Lesson 4 • Brushing Profiles and Mouldings

Addresses brush control in coves, beads, and inside corners. Profiles require different stroke angles and brush sizes than flat surfaces.

Lesson 1 • Finish Viscosity and Reduction

Explains viscosity cups, reduction ratios, and how temperature affects sprayability. Properly reduced finish atomizes cleanly and levels without sagging.

Lesson 2 • Spray Booth Safety and Filtration

Addresses downdraft and crossdraft booth design, filter maintenance, and explosion-proof requirements. Safe spray environments protect workers and prevent fires.

Lesson 3 • Diagnosing and Fixing Spray Defects

Identifies orange peel, fisheye, sags, and dry spray with corrective actions. Systematic defect diagnosis saves time and material on every project.

Lesson 4 • Spray Technique and Gun Movement

Covers gun distance, speed, overlap, and triggering for even film build. Consistent gun movement is the single most important spray skill to develop.

Lesson 1 • Oil-Based Polyurethane Application

Teaches brush and wipe-on polyurethane technique, recoat windows, and adhesion promotion. Polyurethane is the most common consumer topcoat for floors and furniture.

Lesson 2 • Rubbing Out and Final Finishing

Covers wet-sanding sequences and polishing compounds to achieve matte through mirror gloss. The rub-out process defines the final perceived quality of any topcoat.

Lesson 3 • Conversion Varnishes and Catalyzed Finishes

Explains acid-catalyzed and post-catalyzed varnish chemistry, mixing ratios, and pot life. Catalyzed finishes offer superior durability for commercial and kitchen applications.

Lesson 4 • Water-Based Topcoat Systems

Addresses water-based polyurethane, acrylic, and hybrid topcoats including grain raise and compatibility. Water-based systems reduce VOC emissions and dry faster than solvent alternatives.

Lesson 1 • Gilding and Metallic Finishes

Introduces gold leaf, composition leaf, and metallic paint for decorative accents. Gilding adds high-value detail to furniture, frames, and architectural millwork.

Lesson 2 • Faux Wood Grain and Texture Effects

Covers graining combs, rocker tools, and glaze manipulation to simulate exotic grain. Faux finishing expands finishing services to painted substrates and MDF.

Lesson 3 • Distressing and Aging Techniques

Teaches physical distressing, glaze layering, and chemical aging to simulate antique surfaces. Distressed finishes command premium pricing in custom and reproduction furniture markets.

Lesson 4 • Milk Paint and Chalk Paint Systems

Covers mixing, application, and topcoating of milk paint and chalk paint for furniture. These finishes create matte, period-appropriate surfaces popular in custom furniture work.

Lesson 1 • Blending Repairs into Existing Finishes

Teaches feathering, toning, and sheen matching to make repairs invisible on aged surfaces. Seamless blending distinguishes professional restoration from amateur patch work.

Lesson 2 • Stripping and Removing Old Finishes

Compares chemical strippers, heat guns, and mechanical removal for different finish types. Choosing the right removal method protects the wood surface for refinishing.

Lesson 3 • Diagnosing Finish Failures

Identifies peeling, crazing, fisheye, and delamination by cause and substrate condition. Accurate diagnosis prevents repeating the same failure after repair.

Lesson 4 • Water Stain and Ring Removal

Addresses white rings, black water stains, and tannin bleed using targeted chemical treatments. Water damage is the most common restoration challenge on antique furniture.
