Lesson 3: Launching the Artwork: Underpainting & Establishing First Layers

How does an underpainting strengthen composition and depth?
What is the purpose of building layers gradually rather than finishing areas immediately?
How can early value decisions impact the entire painting?
How do artists maintain flexibility while committing to a plan?

Terminology / Vocabulary:
Underpainting
Ground
Wash
Blocking In
Grisaille
Imprimatura
Value Structure
Atmospheric Depth

Structural Foundation

NCCAS VA.CR.HS.2: Organize and develop artistic ideas and work.
NCCAS VA.CR.HS.3: Refine and complete artistic work.
NCCAS VA.PR.HS.4: Select, analyze, and interpret artistic work for presentation

Draft-to-Final Progression: Just as essays move from outline to draft, paintings move from understructure to refinement.
Sequential Logic: Students must think step-by-step about layering and cause-effect outcomes.
Long-Term Task Management: Sustaining focus across multiple days mirrors extended writing tasks

Midway through the lesson, students will participate in a structured “Process Pause” critique to assess value clarity and compositional strength before moving forward.
Purpose: To ensure the artwork is structurally sound before refinement begins. This phase builds discipline, patience, and technical control while reinforcing the importance of strong foundational decisions.
DOK Level: Level 4 (Extended Thinking) – Students must execute strategic decisions, analyze emerging results, and adjust based on visual evidence and critique feedback.

Historic and contemporary examples include:
Leonardo da Vinci – Built layered value structures before glazing.
Rembrandt – Used dramatic value mapping to establish light direction early.
Kehinde Wiley – Begins with strong compositional blocking before decorative layering.
Students connect historical discipline to contemporary studio practice.

Misconception: Underpainting is unnecessary and slows progress.
Reality: Weak foundations result in muddy color and poor depth later.
Misconception: Detail should begin immediately.
Reality: Early detail disrupts overall value unity.
Misconception: Mistakes at this stage cannot be fixed.
Reality: Early layers are flexible and meant for adjustment.

Provide step-by-step visual demo for value blocking.
Offer a value scale reference sheet for students struggling with contrast.
Encourage advanced students to experiment with temperature shifts in monochromatic layers.
Conduct individual progress conferences.
Allow alternative underpainting methods if conceptually justified.

• Visual check for clear value range (lights, midtones, darks).

• Composition remains consistent with approved draft.

• Evidence of full-canvas engagement (no isolated finishing).

Process Critique Reflection:
Students submit a short written reflection answering:

• What adjustments did you make after critique?

• Is your focal point clearly established?

• What is your next layering step?

Summative (Foundation Checkpoint Grade):
Students must demonstrate:

Strong compositional transfer

Clear value structure

Even, intentional paint application

Readiness to move into mid-layer development.

Prepared substrates (canvas, wood panel, heavy paper)

Acrylic, oil, or chosen paint medium

Large bristle brushes for blocking

Rags and sponges

Palette knives

Gesso (if additional priming needed)

Value scale reference charts

Projector for live demonstration
