Thread: Sealing a J-nat

I recently sealed one of my stones with 4-5 layers of tissue paper, because I found a crack. I did a coat of polyurethane and then laid the tissue paper on it and made sure it was as flat as I could get. I did this a few more times and then did 4-5 coats of polyurethane as well. From what I understand, this should help protect against further cracking, but we'll see...

I believe that the sealing of the edges was originally done to prevent moisture from entering the end and edge grain of the stones. During cold weather in particular, the absorbed moisture could cause cracking and delaminating. In those days the J Nats did not live the pampered lifestyle (in J ) that we give them today.

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.
