Water & Moisture Damage
When a burst pipe flooded the storage room of a private collector, a significant acrylic work on canvas was exposed to standing water for an estimated eighteen hours before the damage was discovered. The work was brought to I'Arte Rinasce within twenty-four hours of discovery — a critical window that proved decisive in the outcome.
Emergency Intake & Assessment
On arrival, the work was assessed for immediate risks: active mould growth, paint lifting, and canvas deformation. Moisture mapping using a non-contact hygrometer identified the most saturated zones, concentrated in the lower third of the composition. UV fluorescence revealed early-stage mould colonies along the tacking margins and verso. The paint layer showed localised lifting in areas where the acrylic binder had softened under prolonged moisture exposure.
Drying & Stabilisation Protocol
The work was placed face-up on a padded drying table in a controlled environment maintained at 18°C and 45% relative humidity. Forced-air drying was deliberately avoided to prevent uneven drying stress. Over seventy-two hours, the canvas was monitored at four-hour intervals and the drying rate adjusted by modifying ambient humidity. This controlled approach prevented the formation of tide lines and minimised canvas distortion.
Mould Treatment & Surface Cleaning
Once stable, the mould colonies were treated with a biocide solution applied under controlled conditions. Surface cleaning removed residual tide lines and grime using a carefully selected aqueous system, tested on inconspicuous areas before application. The paint layer was consolidated where lifting had occurred, using a dilute acrylic dispersion introduced under the lifted edges with a fine brush.
Outcome
The work was returned to the collector in stable condition, with no visible evidence of the water damage. A preventive conservation report was prepared, including recommendations for storage conditions, environmental monitoring, and emergency response protocols to protect the collection going forward.
"The seventy-two-hour response window was decisive. Controlled drying, applied with patience, prevented what could have been irreversible loss."
