La Pedrera façade detail after conservation work revealing clean stone

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.

Targeted repairs post heavy rainfall.
