Final Varnishes
The varnishes allow you to protect a work from natural and chemical attacks. They give the painting a uniform matte, satin or gloss appearance.
Apply to a work which is completely dry; this means waiting one year before applying the final varnish. This application of the final varnish must take place in 2 stages: firstly, an application of a first coat of varnish diluted to 10-20%, then after drying for a day or two, of a second coat of varnish which is undiluted or diluted to 10%. Spread the varnish well by brushing in each direction when applying.
