- Advanced chemical degradation leaving the cellulose support extremely fragile and vulnerable to handling.
- Homogeneous layer of general surface dirt accumulated over time.
- Harmful commercial adhesive tapes on the reverse actively migrating acidity into the fibers.
- Poor past intervention consisting of non-archival patches over tears and minor micro-losses.
- Controlled mechanical cleaning to safely lift general surface dirt.
- Precise chemical and physical removal of adhesive tapes and historical patches.
- Technical bridging and mending to structurally consolidate all tears.
- Micro-grafting of tiny losses using long-fiber conservation papers with compatible behavior.
- Selective tonal reintegration of the fills to successfully restore cohesion and flexibility.
