Varnish

Varnish is the protection of your painting. It protects against air pollution, dirt and dust. It also retrieves dull spots in a painting, and ensures deeper colors.
Final varnish may only be applied after 6 months to 1 year, depending on the thickness of the paint layer. Only then  the oil painting will be dry through and through.

Damar varnish:

A shiny final varnish based on natural damar resin. This varnish gives your painting a good protection and a particularly "rich" finish. Moreover, this varnish can be removed quite easily when the varnish layer is being refreshed.
