I am building a small side table (30" semi-circle) with a surface covered with glued-on preserved leaves (The leaves are from a grape vine and I preserved them last year in glycerine solution).
I want to cover the leaves with a thick and hopefully waterproof finish. The finish should be thick enough to mostly smooth out the surface, maybe 1/16" or so. I'm also thinking that I may want to the finish to have an amber color.
I know I could do a pourable epoxy finish, but I think it will be much thicker than I'd like, and it's not particularly the look I'm trying to get.
Various options I'm considering:
- McCloskey's Gymseal: It's mainly for floors, but it's also recommended for bar tops. They claim it very hard, but also a little flexible, which may be helpful for coating the leaves.
- Behlen's Rockhard
- Minwax Helmsman Spar Urethane (which is for both interior and exterior surfaces)
- Regular oil-based polyurethane
In addition, the fewer coats required, the better, and a finish that's easy to apply with room for error (unlike epoxy) would be nice.
If it ends up that epoxy is the really the best way, I may coat the table with amber shellac before applying the epoxy. Maybe instead of pourable epoxy, something like the brushable Progressive Epoxy's Basic No Blush 2 would work (see at http://epoxyproducts.com ).
Clearly, the best thing to do would be some tests on some scrap wood with some of the extra leaves I have. If I mess it up the main table I won't have enough leaves to try again and would have to have to do the table without leaves.
Any sugggestions or advice would be much appreciated
