How to varnish a painting created with Artisan Water Mixable Oil Colour

Varnishes provide a transparent coating which protects your finished painting from dirt & dust. Picture varnishes are usually removable, enabling the painting to be cleaned in the future. Varnishes should not be used as mediums for adding to the colour.

Artisan paintings should not be varnished until thoroughly dry (at least 6 months). There are three Artisan varnishes available – Gloss, Matt and Satin depending upon the desired finish. The painting will benefit from being degreased before varnishing. This can be done with either Artisan Thinner or Artists’ White Spirit (mineral spirits). Simply wipe over the surface of the picture sparingly and leave to dry overnight.

Wiping it very lightly over with white spirit allows you to clean the surface from any grease or grime that has got onto the surface. If there was any trace of grease on your painting and you varnished without cleaning it off, the varnish would reticulate into beads where the grease is. The cleaning ensures that the varnish applies well.
