Painting Restorer Training

Lesson 1 • Ground Layers and Preparation

Covers gesso, chalk, and oil grounds applied before paint layers. Identifies how ground composition affects adhesion, flexibility, and deterioration patterns.

Lesson 2 • Varnishes and Surface Coatings

Introduces natural resins, synthetic varnishes, and wax coatings applied over paint layers. Establishes how coatings age, yellow, and interact with cleaning solvents.

Lesson 3 • Binding Media and Pigments

Surveys oil, tempera, encaustic, and acrylic binders alongside historic and modern pigments. Provides the chemical literacy needed for cleaning and inpainting decisions.

Lesson 4 • Painting Supports and Structures

Examines canvas, panel, paper, and metal supports and their physical properties. Understanding support behavior is prerequisite to diagnosing structural damage.

Lesson 1 • Scientific Analysis Methods

Introduces X-ray radiography, cross-section sampling, and spectroscopic analysis for material identification. Results inform solvent selection and structural treatment choices.

Lesson 2 • Visual Examination Techniques

Trains the eye to detect surface irregularities under raking, transmitted, and ultraviolet light. Each lighting method reveals distinct damage types invisible under normal illumination.

Lesson 3 • Treatment Proposal Development

Synthesizes examination findings into a prioritized, justified treatment proposal. Connects assessment data directly to ethical and practical treatment decisions.

Lesson 4 • Identifying Deterioration Types

Catalogs cracking, cleavage, flaking, blanching, and biological growth as distinct damage categories. Accurate identification prevents misdiagnosis and inappropriate treatment.

Lesson 1 • Safe Handling and Transport

Establishes protocols for lifting, carrying, packing, and shipping paintings without causing damage. Proper handling prevents mechanical stress and vibration injuries.

Lesson 2 • Storage Systems and Furniture

Designs rack, slot, and flat storage solutions appropriate for different painting formats. Storage geometry and materials directly affect long-term structural stability.

Lesson 3 • Integrated Pest Management

Applies monitoring, exclusion, and low-toxicity treatment strategies to protect collections from biological damage. Builds a sustainable pest management cycle.

Lesson 4 • Emergency Preparedness for Collections

Prepares students to write and execute emergency response plans for fire, flood, and theft. Rapid response skills minimize irreversible loss during disasters.

Lesson 1 • Aqueous Cleaning Systems

Covers water-based cleaning using pH-adjusted solutions, chelating agents, and surfactants. Aqueous systems remove ionic soiling while minimizing solvent exposure.

Lesson 2 • Solvent Theory and Safety

Explains polarity, solubility parameters, and evaporation rates as tools for solvent selection. Safety protocols prevent health hazards and accidental paint damage.

Lesson 3 • Cleaning Tests and Documentation

Establishes systematic test-cleaning protocols before full treatment begins. Documented test results justify the chosen cleaning system and protect against liability.

Lesson 4 • Solvent-Based Varnish Removal

Applies solvent mixtures and gels to dissolve aged natural and synthetic varnishes selectively. Controlled application prevents solvent penetration into original paint layers.

Lesson 1 • Facing and Temporary Support

Applies tissue and adhesive facings to protect fragile paint during structural treatment. Facing must be strong enough to hold flakes yet removable without residue.

Lesson 2 • Consolidants and Adhesives

Surveys animal glues, synthetic resins, and acrylic dispersions used to reattach lifting paint. Adhesive selection balances penetration, flexibility, and reversibility.

Lesson 3 • Lining and Relining Techniques

Teaches wax-resin, aqueous, and cold-lining methods for full canvas support. Each system suits different paint layer conditions and institutional requirements.

Lesson 4 • Panel Stabilization Methods

Addresses cradle removal, crack bridging, and controlled humidification for warped wood panels. Panel treatment requires understanding wood movement and grain direction.

Lesson 1 • Modern and Synthetic Fill Materials

Introduces Paraloid-based, Modostuc, and acrylic microballoon fills for flexible or complex losses. Modern fills offer adjustable working time and improved reversibility.

Lesson 2 • Texture Matching Techniques

Replicates original paint texture using stamps, brushes, and casting materials on filled areas. Texture matching is essential before inpainting to achieve visual integration.

Lesson 3 • Leveling and Surface Preparation

Sands, scrapes, and isolates fills to achieve flush, non-absorbent surfaces ready for inpainting. Proper leveling prevents inpainting colors from sinking or appearing matte.

Lesson 4 • Traditional Fill Materials

Covers chalk-glue, gesso, and wax-resin fills used in historic and traditional conservation practice. Traditional fills offer compatibility with aged grounds but require skill to apply.

Lesson 1 • Brush Control and Application

Develops fine brush control for applying thin, layered strokes within loss boundaries. Precise application prevents inpainting from overlapping original paint.

Lesson 2 • Retouching Strategies and Methods

Teaches tratteggio, pointillism, tonal, and illusionistic retouching as distinct philosophical approaches. Strategy selection depends on loss size, viewing distance, and institutional policy.

Lesson 3 • Color Theory for Conservators

Applies Munsell hue, value, and chroma to color matching in conservation contexts. Precise color language enables consistent communication and reproducible results.

Lesson 4 • Evaluating and Finalizing Retouching

Assesses retouching under multiple light sources and at varying distances to confirm visual integration. Final evaluation ensures the treatment meets ethical and aesthetic standards.

Lesson 1 • Final Treatment Report and Handover

Compiles complete treatment records, before-and-after photography, and material specifications for handover. Thorough documentation ensures future conservators can build on the work.

Lesson 2 • Framing and Presentation Standards

Addresses archival framing materials, glazing options, and hanging hardware for long-term display. Framing decisions affect both protection and the visual presentation of the work.

Lesson 3 • Gloss Adjustment and Matting

Modifies final surface sheen using matting agents, wax polishes, and layered varnish systems. Gloss adjustment restores the painting's intended optical character.

Lesson 4 • Varnish Selection Criteria

Evaluates gloss level, yellowing resistance, and solubility of available varnish systems. Selection must balance aesthetic goals with long-term reversibility requirements.
