This study examines the traditional technology of pine tar kilns in Greece, focusing on the case of Distrato in Epirus, where the last traditional artisans reside. Pine tar (katrami) is a viscous liquid produced by the destructive distillation of resinous wood, primarily from pine trees. This practice has a long history globally and in the Mediterranean, with applications in medicine, cosmetics, fuels, and waterproofing for construction and shipbuilding.

This handbook documents a methodology for renovating interior plastering systems on stone masonry using low-impact lime- and clay-based materials enhanced with vegetable fibers. In this regard, it illustrates how a plastering system with enhanced thermal properties can be employed to modestly enhance the energy efficiency of a historic structure without compromising its architectural features. These interventions rely on local, natural materials and techniques based on traditional knowledge and the principles of reuse and recycling.
The research and implementation of the works was part of the project KERETSI.
The creation of the handbook was supported by the INTBAU Grassroots Grants Programme.
