Don't Throw Away Hardened Silicone! How to Reuse Dried Silicone

Silicone freezes and becomes unusable when left on, but in this video we show you how to reuse dried silicone.

You can also reuse hardened silicon to clean abrasive discs, sanding paper etc.

Plenty of other uses for it.

Want to keep open silicone caulk tubes almost forever? Put them in the freezer. It won’t harden in the tip or the tube. I’ve kept them alive for over two years that way. Works with most kinds of caulk and oil based paints as well.

hardened silicone sealant is great for cleaning sanding disks and belts.Make a block of it and use like the shop built item.

Thanks1 You just saved a WHOLE LOT of people some money.

[samTollefson]

That's a good trick!
One thing I do when I know I will not be using it for a while is to tape a 12" piece of 3/8" plastic tubing on the tip and squeeze the plunger until the silicone or adhesive comes out the tip of the tubing then seal the end good. I have gotten 6, or 8 months of storage out of it before the caulk hardens down into the tip.

Put golf tee in the end when done using will last much longer. Use the jumbo long ones and spray wd -40 on the tee as a release agent !!

[desert-walker]

Well that’s a good idea to burn the tip when you’re done to close it up although you didn’t show that here

You have a pretty good idea for the uncured silicone. "reuse dried silicone" is not what you did. Your commenters made a good start though. Without your video, the others would help us actually reuse the hardened silicone.

[asianmikedesigns]

Um, this was more like "how to remove hardened silicone blocking tube passage." how about show me how to reuse hardened silicone through the entire tube.

[jonnafry]

Thought you were going to cut the dried up plug into silicone washers - different interpretation of reusing dried silicone.

[KjV]

I'm not quite sure what you did. Did you melt the tube with the torch and press it on to the other half of the tube?

[mcampbell]

Great idea. I have at least two half filled tubes of caulking that have harden. I was thinking or purchasing those caps that are available on Amazon. They will effectively do same thing as your idea, but they are really expensive for what they are.

На половину засохший, на самом деле... А использование той засохшей части? Можно из неё некие уплотнители вырезать, или шайбы?

[SC.k]

Very very beautiful, thanks for sharing my friend 👍👍👍👍👍👍🥰♥️👈

[andrehamon]

Bonjour, excellente idée, Merci pour ce conseil. Passez une bonne journée

[СтепанБербат]

Ещё засохшим силиконом хорошо чистить ленточную наждачку.

[billhayward]

good hack ! if you're desperate, which sometime happens. BUT calking is only a few buck a tube.

[oskey]

How to reutilize what is not hardened?

[untilnows]

Non ho capito! Il silicone essiccato torna liquido ( in base a quale processo)? oppure è la parte di fondo del tubo (non ancora essiccata) che viene utilizzata?

[malcolmism]

no more wastage. Apart from empty tube.lol
