Fresco [SEP] Conservation of frescoes
The following is the process that was used when rescuing frescoes in La Fenice, a Venetian opera house, but the same process can be used for similarly damaged frescoes. First, a protection and support bandage of cotton gauze and polyvinyl alcohol is applied. Difficult sections are removed with soft brushes and localized vacuuming. The other areas that are easier to remove (because they had been damaged by less water) are removed with a paper pulp compress saturated with bicarbonate of ammonia solutions and removed with deionized water. These sections are strengthened and reattached then cleansed with base exchange resin compresses and the wall and pictorial layer were strengthened with barium hydrate.
