I'm not an expert concerning silicone supplies, however I did see a repair video showing that silicone purchased to make silicone molds with, can be used to repair the surface bases of damaged molds. The type of silicone used self-levels while curing. It adheres itself to most [not all] other silicone. Sold over at Amazon.
I used a modified concept for this to fix a silicone stamp that was inconsistent in terms of thickness (there were some problematic air bubbles on the back of it, which meant it was applying pressure improperly in the same places every time, so there were always the same gaps in the image). What I did was I placed the front part of the stamp on an acrylic block, put silicone caulk on the back, and pressed another acrylic block on top of that to make sure that everything was pressing evenly/the stamp adhered to the acrylic block on the back properly. After the silicone dried, the stamp came off the acrylic block just like a standard silicone stamp, and it actually presses evenly now! (It's possible the new silicone backing will come off eventually, but at that point I should be able to repeat the process if needed.)
It depends on the silicone, you will want to see what the set and cure times are on the silicone you are using. Its normally no more than a couple of days.
I've heard that petroleum jelly and vegetable based cooking oils are safe to use as a mold release. I haven't tried it yet as I want to verify it to be true beforehand. I'm not in a position where I can afford to purchase anything at the moment.
It might work with tiny silicone molds with little surface area, but try at your own risk with our large molds. Youll likely see some damage and reduced life.
Great tips on filling mold tears. So far I haven't had any, but I will definitely be saving this video just in case!
You just saved me a bucket of money! Thanks so much- I’m off to find my caulk & fix all of my damaged molds!
Happy to have done it to help!

Well done. Any suggestions: the little silicon piece that makes the handle on my chercouterie mold broke off. Any repair suggestions?
Hi Daniel. This video would be the best video to follow to try and repair it, however if the entire handle is broken off, its likely needing replaced.
Awesome! Thanks for sharing!
How soon after applying the silicone repair can I use the mold, and will the silicone repair stay intact after releasing an epoxy project?

thanks for the tip man
does the HOME DEPOT SILICONE work on PLATINUM MOLDS ?
As long as its pure silicone without acrylic in it, I don't see why it wouldn't

Please don't use your fingers to wipe your knife blade! Ask me how I know.....😬
LOL. I think I can guess! :-) Ok folks.. don't do this.
