Thread: Sealing a J-nat

I seal the edges of my J Nats with several coats of pure cabinet makers laquer. Dries quickly and leave a nice low gloss finish. I use the same laquer on my naguro's over the stamped area only.

To further reinforce the stone you can also add a layer of tissue paper around the sides and lacquer it, and if you want to go all the way mount it on a base.

This is interesting Stefan. How many coats ? No problem with water affecting the shellac ?

I've been using my oozuku asagi for a few weeks now without sealing it first. From what I'm reading in the forums this may be a bad idea, correct? I do have clear nail polish at home that I can use...but no shellac on hand.

Has anyone actually proved this is being something you should definitely do or not? We don't keep our stones outside like they did in the past or like carpenters sometimes do now.

Maybe sealing jnats should be in the wiki...

Oz,
sorry did not see your post earlier,
I do 3-6 coats, and have no problems with water. Some of my stones have been sealed for like an year and I have no issues whatsoever.

The only stones you need to seal is suita stones because they are layered and water might cause delamination. This will only happen if the stone is put trough extreme temperature cycling such as leaving it out at night at freezing temperatures. One other reason to seal a stone is to prevent splitting from existent cracks in the stone, if the stone is not cracked then you do not have to do anything to it. I personally seal all my stones that are not cracked because I just feel like it and no other reason.

Aoto also are prone to cracking but I imagine not many use Aoto on razors

Yes those too, as a matter of fact Aoto might need even more than lacquer, I'd put a layer of tissue paper to hold it together.

Try washi instead of tissue paper.

I would but I can't seem to find a source here in US. It also is not very cheap. I did one low quality Aoto as per the advice of So, and it worked well, I use cashew lacquer for the job. One thing I did not like is the texture not smooth.

There are hundreds if not thousands kinds of washi.

Use a thin almost transparent and smooth one.
