During the recent restoration of George and Martha Washington's Tomb, Pen Austin, Henry Orton, and I carried out extensive replastering following damage to the roof system and ongoing drainage issues. Prolonged moisture infiltration had led to widespread deterioration of the interior plaster, as well as the wood lath and framing behind it. Once the damaged materials were carefully removed, the underlying structure was repaired and stabilized, restoring a sound substrate for the new work.

New lath and nailers were then installed to match the original construction approach, and the walls and ceiling were replastered using a traditional two-coat lime plaster system. This work restored both the visual integrity and the breathability of the interior surfaces. Throughout the process, emphasis was placed on material compatibility and the long-term health of the structure, allowing the space to dry, breathe, and age naturally without placing undue stress on the historic fabric behind the finished surface
