School of Constructive Arts – Exterior Lime Plaster Intensive with Tim White

This March veteran natural builder Tim White will join School of Constructive Arts to teach a 4-day intensive workshop on exterior lime plasters tailored to construction professionals who aim to master the enduring craft of working with lime.

Lime plaster is an ideal exterior finish for earthen buildings. While cement stucco traps moisture and exterior clay plasters require frequent maintenance, a well-applied lime plaster is both breathable and extremely durable. Tim’s lime plaster method, derived from decades of experimentation and deep research into historical techniques, builds up a robust, breathable, self-healing skin of limestone that can protect a building for decades.

Topics include the lime cycle, microvoids and watervoids, pozzolans, sand gradation, bulking sand, balanced mix design, and application. Students will learn how to make their own mixes, apply plaster with a hawk and trowel, how to wood float lime plaster and when to do so, and how to make and apply a limewash to make lime plaster self-healing.

Space is limited to 15 participants.
