I never used polymer resin before. Would like to get a clear heavy coat completely covering a small wood item. Say a piece of wood 2"x3" with a sticker on one side, can I submerge the whole item in the resin? won't the resin run off when I hang the item up to dry? will it take more than one coat? does the wood have to have a prime coat of some kind? any help will be appreciated...thank you, hugh/ohio
Acrylics would be a good option. Higher viscosity will prevent the coating from sagging too much. I'd suggest that you post this into some of the art groups in the "rec." hierarchy for suppliers and the voice of experience.
If you are planning on letting the resin cure while the wood is hanging, won't you have a noncovered area where you are hanging the object from?

Dear Hugh,
The main problem with wood coating is that humidity is entrapped within the fibrous structure, and that it continually breathes i.e. there are water and air exchanges, so coating is not as easy as it can appear at first glance.
First advice I can give you, although I'm not a specialist, is to work on dry wood. Second one is either to fill the porosity with a low viscous product, some kind of primer, on which you can put your coating afterwards, or to use a microporous coating. In the latter case, acrylics are effectively, as John said, a good option. We can formulate it to prevent it from sagging, even though it has been applied in thick films. In the first case, we'd rather use solvent-based primers because capillarity works better, and the topcoat is rather thin (< 60µm) but formulated with UV-absorbers to protect the wood well.
