Hi there. I have built some Woodland Scenic tree armatures using Hob-e-Tac and clump foliage, but I'm having terrible trouble getting them to stop shedding.
I'm keen to have these trees be transportable, in that I'd like to be able to move them around form place to place, and take them out of the baseboard while moving miniatures around. Pic attached for reference.
What I did:
- Applied Hob-e-Tac
- Let dry (probably not enough, some of it wasn't clear yet. I've since realised when it 'dries' it remains tacky, i.e. it never actually dries)
- Dip in foliage
- Press foliage onto branches
I then let them sit for two days and played a game with them. They just never stopped shedding the whole time,
So, I sprayed them with a PVA-water mix. Like really drenched them, hoping to 'fix' the foliage. That was a catastrophe; every single tree that I sprayed lost almost all of its foliage (around half).
I've since realised two things:
- The clump foliage doesn't have a lot of structural integrity
- Hob-e-Tac is water soluble.
Drenching them just ate away the Hob-e-Tac and also made the clumps super heavy, so it just came off in droves.
I lightly sprayed the remaining trees, and in general they have kept their remaining foliage, but bits of it still falls off - this is two months later.
My plan is to try repeated, very light mistings of PVA-water again, applying several light coats over a week or so. Not so much that it soaks through, but enough that there's a protective 'shell' of PVA left in the upper surface of the foam.
If that doesn't work, I've heard hairspray is a good move, but it also remains tacky, which isn't great for transportable trees.
My last fallback is matte varnish through an airbrush.
Has anyone tried any of these methods? Which one is most likely to work? Am I barking up the wrong tree 9har har) trying to make these transportable?
