This is my approach to fixing peeling shoe sole layers. I cleaned and even Dremeled the inside layers of rubber to help glue adhere, but I was like “How the hell should I apply pressure while glue dries?”…
So I figured I should easily be able to do that with some thumb tacks in the sides of the sole, and temporarily stitch it down with dental floss for a day or two while the glue dries.
Wish me luck, I used silicone glue. Not sure if that’s the best glue or not for the purpose, but it’s tough and flexible. Of course I did both shoes, just figured it would be more obvious what I did with one shoe showing the initial damage.
Anyways, thumb tacks and dental floss for the win to hold it together while it dries!
Edit: Confirmed, my fix is solid, even holding better than the original factory glue! Haters gonna be haters though, carry on with your downvotes if you want. Just sharing my technique of salvaging shoes for less than $5 of glue and stuff around the house.
If glue was strictly a chemical reaction, then it would cure itself in the tube on a warehouse shelf before you even purchased or opened the glue. But nope, it takes exposure to air before glue actually dries.
Sounds like you’re thinking of epoxy, which is distinctly different than glue and comes as two separate chemicals meant to be mixed just before use and actually can cure without exposure to air.
Edit: Silicone glue breaks down and becomes a liquid again with solvents such as acetone. Same with E6000 (which I’ve also used before). Water isn’t the only liquid substance that makes things wet ya know…
Well, I just checked Wikipedia and we are both right:
" Even if it is strongly associated with the production of thermosetting polymers, the term “curing” can be used for all the processes where a solid product is obtained from a liquid solution,"
Glue that reacts with oxygen in the air is a process that produces a solid from a liquid.
Epoxy is a really long hydrocarbon chain.
There is no mention of curing and solvents. I normally think of drying as water leaving because no chemical reaction occured, and the original substance properties return with water added.
Shrug, I learned that it shouldn’t be a pet peeve.
