Cob and Natural Plastering Workshop

Come learn about the beautiful and fun application of natural earthen plasters as we work to finish Urban Adamah’s cob classroom and mud kitchen! We will discuss the basics of natural building; how-to prepare materials for an earthen plaster; how-to test different sand and clay ratios to find the right plaster for your structure; the different types of plasters and plastering techniques; and more! Most of the workshop will be hands-on – mixing materials and learning how to apply them to the earthen mortar (cob).

Please bring a water bottle and clothes and shoes you’re comfortable working in and getting dirty. Other optional items include a notebook (optional), rubber gloves (optional), a trowel (optional), and plastic yogurt lids (optional).

Tickets are $25-$55 sliding scale and space is limited. All proceeds go towards Urban Adamah’s natural building program for our children’s garden.

Accessibility Notes: This event will be held in our Children’s Garden which has ADA accessible pathways. While the program will involve working with tools and dirt and building close to the ground, we are committed to accommodating all abilities. Please bring layers and rain protection. FM receivers are available for those hard of hearing. We have one designated accessible parking spot in our lot. If there are no available parking spots in our lot, there is street parking surrounding the site. Please allow time for this, as our parking lot can fill quickly.
