GUSTAV BERGER'S ORIGINAL FORMULA® PVA INPAINTING MEDIUM
A concentrated retouching medium, based on PVA (polyvinylacetate) in a 35% solids solution. Gustav Berger’s Original Formula
PVA Inpainting Medium should be diluted in ethyl alcohol (1:4), with whom is also reversible; it wets readily the dry pigments to which it is added to produce very saturated and transparent glazes.
It is especially suited for oil paintings, gouaches and tempera, while it is not suited for most modern acrylic paintings whose colours are usually soluble in ethyl alcohol and toluene.
