Thread: Sealing a J-nat

I have a J-nat which I bought unsealed. It may be my imagination but I think I see a crack developing so I want to seal it. I have read some posts about cashew /urushi lacquer and whilst I appreciate that this is the traditional way to go I wondered what would be an acceptable alternative that would be more readilly available.

Thanks
Claude

I use water resistant vinil glue, inexpensive but a good solution, it take some days to completely dry, but it's inexpensive and effective

Thanks. Would a clear epoxy glue be suitable?

You can use a spray can of automotive clear coat or any clear that is an alkyd ester.
Water resistant & tuff but slippery when wet.
Just put the stone face down on a cloth to prevent runs onto the work surface. A few quick sprays & you're done.

You can also use your wife's clear nail polish. Just don't let her catch you.

I've actually never understood it. I always thought the sealant was to protect the stamps.

After-all it's a rock and putting a coat of whatever on will not stop a crack. Most start internally anyway.
