One of the banes of watercolor art is that it must go behind glass when framed. Glass and plexiglass have inherent problems: breakage, warping, glare and condensation. For these reasons, many galleries and customers shy away from watercolors.
(Always use plexi - it's lighter, and if it falls, it doesn't break and shread your artwork or your body!) CondensationIn direct sunlight, a fog builds up on the inside of the glass, not only creating an ugly, blocked view of your art, but also exposing your art to moisture which can be damaging over time.
Glare and ReflectionBoth glass and plexi produce glare and reflection making it difficult to enjoy the full beauty of watercolor. Never use glare-free glass or plexi - it's sort of frosted and makes the work look blurry.
Please share if you've found a glare-free product that works!Glass-free SolutionA technique you can use to get away from glass is to borrow from the Acrylic artist's toolkit and use two products to coat your final work: a spray fixative followed by a UV acrylic clear coating. For a fixative, I've used
Ampersand's Clayboard Fixative (although another watercolor artist told me Krylon products are fine too). Once the artwork is fixed, either roll on or brush on two separate coats of
Golden's Polymer Varnish with UVLS. Let the first coat dry thoroughly, then take a rag and burnish the surface. Apply a second coat, let dry, and burnish again with a rag.
Both products are non-yellowing and made for the fine art market. For "archival" concerns (if you are destined to become the next Georgia O'Keefe), both are removeable and even provide
removal instructions on their web sites.
I use Golden's Gloss Varnish because it lends an incredible saturation to your colors - making them look wet again. It also creates such a nice barrier that you can spill coffee on your work and wipe it off with a damp rag! Another artist I know uses the Matte finish. My tests show the Matte finish doesn't create the strong anti-coffee barrier, but it does yield the most natural-looking results - your painting looks the same. In fact, I'm thinking about using the fixative + matte UV coating on my paintings that go behind glass in order to give them that much more longevity and light fastness.
Framing Glass-free WatercolorsWithout the glass, people can easily mistake your watercolor for some other medium (people think mine are oils). Therefore, I like to frame my coated pieces just as I would a normal, uncoated piece: using a wide fabric matte, filet, and gorgeous frame. For a more modern look, I have also had my paintings mounted to
gatorfoam for rigidity (which is acid free and much stronger than foam core) and then framed in a
"floating frame."
