Sagrada Família Restoration Guide - How the Details Are Preserved

Conservation at Sagrada is a continuous process: assess, test, intervene lightly, and document every step.

Core methods

• Surface diagnostics before any cleaning pass.
• Minimum-effective interventions to preserve tool marks and depth.
• Targeted repairs for grout, joints, and vulnerable ceramic edges.

Why it is delicate

Over-cleaning can erase legibility, while under-treatment accelerates decay. Balance is the craft.
