Thread: Sealing synthetic waterstones

I've only ever sealed one synth, though Max at JNS recommends sealing all stones natural or synth. The Shapton Pros appear to be sealed on the sides (and on the back for the old ones and Kuromaku) with something like tile sealer or what the Japanese called 'Hone Coat'.

Once I tried sealing a large Suehiro 1k - basically a King 1k - with lacquer to do what you mentioned, reduce water absorption. It failed miserably. However, it dried out in about the same time, many days lol, so I don't think there's any risk of water staying in a hone that you'd perma-soak anyway.

I definitely wouldn't seal a stone that I perma-soaked, I'd doubt that the coating would stay on over time and I don't understand what you'd accomplish by coating a perma-soaked stone.
