Anna Kłosowska, Michał Obarzanowski • Plaster casts in the collection.
Before the application of latex, the surface of the plaster cast was carefully and pre-
cisely dusted and vacuumed using soft brushes and Progress-Micro vacuum nozzles.
Next, two coats of latex were applied one by one, after the first layer had dried (fig. 11).
The vulcanized film was removed after approximately 6 to 12 hours, although it can
be removed up to 3 days later, depending on environmental conditions (fig. 12).
If needed, the latex application was repeated until the desired effect was obtained.
This method showed to be time-consuming and quite expensive, so in some cases
modified polyvinyl acetate was used where applicable. For example, on the reverse
