Conservators combine surveys, laser cleaning, and micro‑mortar repairs. Ironwork is de‑rusted, primed, and painted; painted plaster is consolidated.
Practices
- Diagnostics: map material decay to guide interventions.
- Minimalism: least invasive methods first.
- Documentation: before/after records assure continuity.
Material ↔ Method Matrix
| Material | Method | Goal |
|---|---|---|
| Limestone | Laser cleaning; consolidation | Remove grime; stabilize |
| Ironwork | De‑rust; prime; paint | Halt corrosion; protect detail |
| Plaster | Consolidate; retouch | Strengthen; color fidelity |
Conservation is a dialogue: past intent, present science, future care.
Care Schedule
- Periodic surveys for façade and courtyards.
- Targeted repairs post heavy rainfall.
- Repainting cycles for ironwork.
