I tried both, they are very similar. However, aquilim 315 is still somehow sticky after it completely dried. It might make your finger dirty when you try rub off the dried glue on the spreader. Ecostick doesn't has this issue. I haven't test which is stronger. But both are strong enough to glue leathers togethers. I would prefer ecostick. However, as I live in Germany, it is expensive to import it from other country. So I mainly use aquilim 315, which I can find in many online shop here.
In Brazil🇧🇷 it is not sold, I bought it today on eBay from France and I want to try it to tell my Brazilian friends. We have other national water-based glues. But this one seems to be the best.
Love the 315. Renia’s Colle de Cologne is my favorite solvent based adhesive and the additional primers or catalyst make it glue anything from PUR, TPR, oil soaked EVA, or even tits on a bull.
Hopefully you’ve figured this out within 2 years, but if not, here’s a few tips. First and foremost, glue film thickness is paramount. Too thin, particularly porous surfaces like leather, is not good. However, with water based adhesive like 315, you’d be surprised how thin it needs to be, think Saran Wrap thin, and only one coat. The silicone spreaders like in this vid can’t smear the glue in hard enough, but plastic Japanese spreaders do (Yonezawa has the best). Thick glue film will absolutely mess up your burnishing. Sanding with course sand paper (220ish grit) and working up to 600 knocks the glue down. Then what works for me is to polish with bees wax, sand with 800 followed by canvas, more bees wax, 1000 grit, wet the edge, and finally bees wax and canvas polish. You can still use Tokonole at this point,which helps to bury any tackiness left from the glue.
