Varnishes

Solvent based varnishes will be fine for both oil and acrylic, while polymer based ones are only OK for acrylic paintings so please check before each one if it mentions A(crylic) OK / O(il) OK or A&O OK. We also stock some varnishes for watercolours and gouache please go the the relevant sections.

Blockx Amber Varnish, Gamblin‘s Gamar picture varnish, Golden : MSA (Mineral Spirit Acrylic) Varnish with UVLS both in liquid form and in an aerosol as well as their Polymer Varnish with UVLS, Langridge : Retouch Varnish / Damar Varnish / Picture Varnish (comes in Gloss, Satin and Mat) / Wax Varnish, Maimeri & NAM.

Why bother varnishing? It is the varnish’s function to prevent dirt, smoke, etc. altering the paint surface. It is much easier to remove a dirty varnish and replace it than to remove dirt from the painting itself, potentially damaging the paint-film. Some companies like Golden even suggest adding a layer of non removable Gel topcoat (their is with UVLS protection) to seal in acrylic paintings, if later the varnish has to be removed, there is then no chance of tampering with the actual paint layer.

A few varnishing rules… Acrylic paintings are ready to varnish after a few days (weeks if it’s really humid out there), whereas an oil painting should be allowed to fully “dry” for at the very least three months before final varnishing (some companies recommend up to a year!) and, obviously, the thicker the paint layer, the longer the drying time. If you wish to give temporary protection to an oil paint surface the application of Retouch Varnish is recommended (it is also useful to give you a sort of preview of the varnished work).  When you are ready to varnish, please remember that a couple or even three thin layers of vanish are much better (and in the long run faster to dry) than one heavy layer. If you are using a spray, we recommend you do it outside, on a non windy day, shake your can a long time (like two whole minutes!!) and then start spraying outside the surface you want to cover as sometimes the initial spray can deliver a heavier load of varnish. When you are applying with a brush, do not start at the top left corner (a reflex that comes from writing I suppose) but put two or three random patches in the middle than push one way the varnish to the borders than the other way. Let your layer thoroughly dry, then reapply. For a very glossy effect, you might wish to use a last layer of  gloss varnish spray as a little eye teaser… the micro particles tend to catch the light more than a compact layer. Whatever the method used, deep breathing and a little prayer might be in order before you proceed.
