A quick hobby tip that I thought I would share in case anyone else comes across the same problem. I tried my hand for the first time at making my own trees for wargaming using the Woodland Scenics Armatures and their clump foliage. I couldn’t get hold of their Hob-e-Tac glue for attaching the clump foliage, so used a tacky glue bought from Hobbycraft. Not sure about this, but I assume it was supposed to be similar. Anyway I got the clump foliage to stick to the armatures which was the first stage. Then what you are supposed to do is spray the tree with Woodland Scenics Scenic Cement (basically watered down PVA), which I did but that resulted in most of my clump foliage simply falling off straight away!
Now this might be do with the tacky glue – perhaps Hob-e-tac is amazing – although a search on the internet seems to indicate it is not. I tried some alternatives. Super glue fixed the clump foliage perfectly and strongly, but I didn’t fancy using my tiny tube of super glue on lots of trees, so I looked around for something else. I had some Bostik Contact Adhesive for making Peter Dennis’s Paper Soldiers. I tried this – you’re supposed to attach to both parts and then wait for it to dry four minutes to get a good bond. I did do that, but gluing bits of clump foliage was not ideal, so I thought why not just plonk it on the armature and see if the clump foliage will stick straightaway – and as Bob Ross would say I had a happy accident! It worked like a dream. A really solid fix. I tried spraying the Scenic Cement on and that worked great as well – no bits of clump foliage dropping off.
So the long and short of it is try Bostik Contact adhesive for sticking clump foliage to stuff!
