Yup. Any alkyd resins work fine.

I've sealed a aoto and a French Stone which the Name of Escapes me at the moment. It works just fine and it's definitely a lot safer and cheaper. And correct me if I'm wrong but I believe that most Lacquers are not 100% water proof.

Clear auto sprays are of course 100% waterproof.

I have used Urushi, got it from Japan direct. Not sure how pure it was, but it was not fun to use. I had no reaction to it, but I knew the consequences so I used gloves respirator and thinned it with Turpentine. Took 3 days to dry per coat. I did not use it after because ti is not worth the hassle IMO. Cashew lacquer is available in US and is cheaper option if one wants to go more traditional.

Many products are available to seal certain stones edges or labels. Typically only the sides need to be sealed. Some are easier to use than others.
Here is a j-nat I sealed w/ urushi laquer and gold dust pigment sprinkled in.

That is truly a beautiful stone and job of sealing it. I wished that stone had still been available on Alex's page glad it got a proper home.

I use this for sealing my stones and labels. Works great. Just use painters tape over areas you don't want sprayed and use a spray handle with light sweeping sprays over area to be applied. Let dry and layer to your satisfaction. Simple and cheap at your local hardware store.

Thank you sir. That was the first stone I purchased from Alex. Just HAD to have it. It gets some use now as it covers a wide range, the heft makes it a nice hand holder hone stone. Does that sound weird?


Water based varnish works well and is non toxic.


Clean and dry stone prior to sealing. Mask off area to protect and create straight edge.


Besides protecting the sides of the stone, tissue or mesh can be laminated onto stone surface to reinforce cracks or fragile areas.

Wow, both stone and sealing look stunning.
Could you elaborate on the process, like did you prepare the stone, did you use the urushi diluted or undiluted, how many layers of lacquer, did you sand the coats of urushi after curing/before applying the next etc.?
Also is there any way to make sure the urushi has fully cured?

This would be of great help, as you might have guessed I'm finding urushi intriguing and might give it a try.

Kind regards

Regretfully time constraints make that difficult. Woodworking and lacquer application guides exist that are much better than I could ever give. If you decide to use Urushi, what has been said about it's hazards are correct. Take the proper precautions.

These may help to understand the scope of Urushi applications. I have done razor scales w/ Urushi which is difficult.. If you like a challenge please proceed.
