As soon as I finished this watercolor on heavy weight Yupo I realized it was the exact size of the old wooden serving tray that I was planning to freshen up with some sort of art work. Wouldn't you know I want to put Yupo on a tray! Well, we'll see how this goes.
I gave the tray a base coat of acrylic paint to seal it. Then a few days later, I sprayed the Yupo painting with about 6 coats of Krylon Kamar Varnish (for oil, acrylic and watercolor paintings). After that dried, I applied an even coat of YES glue to the tray and glued the paper to the tray, using a brayer to smooth it and get out an air bubbles. Now I am waiting for that to dry.
I am reluctant, however, to even think for one minute that the varnish will be waterproof enough that I can set a glass of lemonade on this tray. My next step, in a day or so when the glue has thoroughly dried, is to apply a coat of Liquitex Gloss Medium and Varnish. Now this medium has been developed to cover acrylic (not watercolor) so I have no idea how this is going to work. I thought I'd use a soft sponge brush, trying hard not to go over the surface more than once. I may decide on two coats. Anybody have any thoughts on this?
Well, if it works and it seals it, this is going to be fantastic! Keeping my fingers crossed for you - I haven't much experience with using yupo for anything but a painting that is sprayed a few times with Krylon finish. If you succeed, you may come up with something other artists want to try!
