Course Outline

Goal

This seminar will address the mechanics of old paint and coatings, the application of this knowledge to various treatments, and the prediction of future behavior in various RH and temperature conditions.

Description

This seminar will focus on various elements of the mechanical behavior of paint film, mainly viscoelasticity and viscoplasticity. The response of paints, ground, varnishes, gelatin, glue, and gesso layers to temperature, moisture, solvents, and time will be discussed; causes of cupping will be examined; and the effects of relaxation treatments and adhesion processes on the manipulation of paints and coating layers will be demonstrated. Participants will work with paint properties charts. Questions and discussion will be encouraged.

Learning Outcomes

Upon completion of this seminar, participants will be able to:

• apply the most up-to-date information to treatment and preventive conservation decisions

Target Audience

Conservators of paintings and polychrome or painted objects

Note: Participants should be comfortable with graphical presentation of data and have familiarity with conventional treatments of paint films.
