Impasto is an oil painting technique that compliments painting alla prima, which means “in one go.” By applying thick paint straight onto the painting surface, the artist may enjoy using bold and expressive brushstrokes in rendering skies, cornfields or seas.

Painting impasto is also ideal for expressing emotions within a painting, as the Expressionists did. Impasto is a painting technique which is thick application of paint that makes no attempt to look smooth. Instead, impasto is unabashedly proud to be textured, and exists to show off brush and palette knife marks Oil painting techniques such as using palette knives and Sgraffito are ideal with impasto.
