Learn about natural plasters with me in Medford, MA! We are running three sessions this summer.
In just three hours, you’ll learn the basics of how to formulate and apply a durable and beautiful clay plaster from local soil, straw, and sand. We’ll also discuss and demonstrate lime plasters, giving a complete overview of natural plasters.
Clay and lime plasters are ancient and highly effective ways to seal many types of walls, and you might be surprised to learn how many applications they have, from traditional buildings to modern renovations and artistic applications. The best part is, they are nontoxic and totally DIY-able.
This is a hands-on workshop: in each step, you will get tactile experience with the materials. Clay plaster is one of the most delightful natural building materials to work with: cool, squishy, clayey, and just begging to be frosted onto a wall like a giant cake. You’ll have the opportunity to apply your new skills in real time by plastering a light straw-clay tiny house! This makes for a great setting to talk about the broader context of clay in wall systems, and the compatibility between different materials.
