MATERIALS DISCUSSION: A Practical Guide to Using Linseed Oil Paints Today
Thursday, June 20, 2024
3:00 pm - 4:00 pm ET
The presentation will examine the applications of linseed oil paints and explore their role in the preservation of historic resources. The components of linseed oil paints that are used today and factors that contribute to the successful use of these paints will be discussed. This includes surface preparation, application tools, and application methods. A case study will be used to illustrate these points.

LUNCH & LEARN:
Mineral Silicate Paints & Stains for Masonry Facades with KEIM Mineral Coatings of America, Inc.
Friday, August 16, 2024
12:00 - 1:00 pm Eastern (US)
A discussion with Periri Robinson of KEIM Mineral Coatings of America, Inc. KEIM mineral paints are a Bavarian invention by the scientist Adolf Wilhelm Keim, who successfully combined water glass (potassium silicate solution) with inorganic color pigments. This produced a paint that both penetrates and chemically reacts with the mineral substrate, becoming an integral part of the surface where it can never peel or blister. In addition, unsurpassed weather resistance, durability and nonfading color are hallmarks of mineral silicate finishes.

Materials Discussion:
Assessing Drayton Hall’s Decorative Plaster Ceiling
Thursday, October 24, 2024
5:00 pm Eastern (US)
Since the 1970s, several plaster conservation projects were undertaken to preserve the decorative cast plaster ceiling in Drayton Hall, a c.1750 house in Charleston, South Carolina. The subject of several publications and conference presentations, these treatments are well-known to many and include added mechanical fasteners, plaster patches, and epoxies. Less understood was how the various treatments could be expected to perform over time, especially in an unconditioned building where materials cycle through dramatic changes in temperature and humidity. In this Materials Discussion, you’ll hear from and talk with members of the project team who assembled at Drayton Hall in 2024 to assess the condition of this plaster. Presenters will address which NDE techniques they liked best, what they observed about how the treatments performed, and what happens next for this ceiling.
