Impasto Without Regrets: How to Paint Thickly Without Structural Failure

Overview

Impasto is one of the most visually compelling techniques in oil painting. It can intensify light, reinforce form, and give a painting a physical presence that cannot be achieved with thin paint alone.

It is also one of the most misunderstood.

Many of the problems associated with impasto—cracking, wrinkling, sinking, or long-term instability—do not arise from a single mistake. They result from how thick oil paint behaves as a material system.

This session examines impasto from a technical perspective:

• How oil paint dries and cures
• Why thick paint behaves differently than thin paint
• The mechanisms that lead to failure
• What historical painters did—and did not do
• How modern materials change the risks
• What practical decisions reduce those risks in the studio
