Lefranc & Bourgeois J.G. Vibert Retouching Varnish 75ml
Retouching varnish is used to eliminate sinking (areas of a painting that become matt owing to the absorption of the resin and/or oil by the underlying layers). It is also essential when retouching old paint that has dried out, to ensure a link between the old layer and the new layer of colour. Finally, it is also used as a temporary varnish while waiting until the final varnish can be applied.
Caution: Never apply the final varnish to an oil painting before 6 months to 1 year. The consequences are serious because any future varnish removal and restoration will become impossible.
With acrylic and ketone resin,quick drying petroleum. It contains the most resin with 25% dry
extract after drying.
