ground, especially in parts done in green. Injections of Primal AC
33 and Movilith DC 50 were used to attach the original mortar to
the wall, before the removing of the superimposed layers of plaster
started. A special apparatus was employed to exert pressure on the
peeling blisters after the injections had been made. In places where
large fragments had started to peel, the blisters were filled with a
mortar of hydrated lime and sifted and washed sand with addition
of Vinavil. Scalpels and chisels were employed to clean the painted
surface mechanically; the final cleaning was done with the aid of
glass brushes and bread rubbers. Weakened parts of the
poiychromy were reinforced with a 3 % solution of Paraloid B 72
in ethyl alcohol. The edges of the paintings had a lime-and-sand
mortar (1:4 hydrated lime and sand) band put on to reinforce
them. Damages and loses of the painted surface were filled with
the same mortar. The undecorated fragments of the western and
northern walls were covered with new plaster.
