The community is invited to join fourth-generation plaster specialist Matt Luczak from Chicago Ornamental Plastering and historic mortar specialist Matthew Wolf of Henry Frerk Sons to learn why everyone should save beautiful plaster walls. There will be information on the numerous benefits of plaster walls vs. drywall, the most common issues old plaster walls face, and learn the proper ways to fix them. Attendees will make their own plaster molds.

This free class will take place from noon to 1:30 p.m. on Feb. 23 at the Evanston ReBuilding Warehouse, 2101 Dempster St.
