Has anyone used the stick-on corks from Jo-Ral? Do they last? I need to replace the corks on my Humes & Berg cup mute. Thanks!

Most of the replacement corks I've seen require some kind of adhesive.

I've never had any luck with film adhesives that are cmmonly available (think double faced tape). Generally you need a strong adhesive designed for cork or leather. Barge cement is one. I've also had some success with hot melt adhesive, Super Glue or cyanoacrylates aren't good.

Cheapest way to replace cork is to buy one of these hardware store cork disks for kitchen ware, contact glue, sandpaper and a scalpel. That should last for many Mutes. Or a pip-up cork board.

I've found corks as a result of internet searches, and I used to use hot glue to attach them, but lately I've used Titebond wood glue; it's easy to use, easy to clean up, and it works!

I used Gorilla Glue. Been good for a couple years now.
Instead of peeling off the old corks, just put the new corks between the old corks on fresh unglued space.
After you glue them on a rasp will do a nice job of shaping the cork.

I used a concrete sidewalk once when I didn't have a rasp.

But a 4 way rasp is a very useful and inexpensive tool. It has coarse and fine, rounded and flat rasps in one piece.

+1 for Gorilla Glue

I can testify that they do last. I've had these on a Humes & Berg cup mute for the last few years, no issues.

I don't use Gorilla Glue for the reason that, once opened, I have found it hardens in the container, rendering the remainder unusable. I'd say that if you want to use GG, get the smallest amount you can find, as it can become a one-use product similar to cyanoacrylate.

I think it's designed so that if you shake it really hard after it's hardened in the bottle, it becomes a gel again. I've always hated when glue hardens in the bottle, then I noticed the fine print on the GG bottle where it said to shake it really hard, and it surprisingly worked.

Interesting. It's been a long time since I've used it. Thanks for the info.

I replaced some old corks last year with these and used Gorilla Glue. Humes and Berg 3 Pcs Set Cork Trombone Straight and Cup (CORK2) https://www.amazon.com/dp/B007H4IZ68/re ... jEbEGS6ZBB
