The whole conservation and restoration procedure was designed so that a reversal of the process would be as easy to achieve as possible, given that the greater part of the mortar layers had been removed.
Being aware of all this and recognising that when the time comes for the next major work on the painting it is quite likely that the written records may not be readily available, it was decided that all restoration work should involve the use of synthetic materials so that a future restorer would be able to easily distinguish between the original Roman material and the modern substitutes used in the restoration.
It is recommended that any reversal of the restoration process should bear the following points in mind.
It is recommended that at this stage that the Roman material be faced-up using a water soluble adhesive as all the interventionist material material is synthetic and solvent based.
Removal of the synthetic intonaco. As the synthetic intonaco is a PVA based material (see above and the Materials Appendix), the application of a suitable solvent should soften the material so that it can be removed.
The synthetic arriccio should be removed in a similar manner.
At this stage it should be possible to to identify the different panels so as to allow their separation and removal from the mild steel frame.
