Thread: Sealing synthetic waterstones

Personally I think that sealing any stone natural or synthetic is fine but I wouldn't bother sealing lower grits,I can't see the point in that.
Maybe if I would have sealed the 10k straight away then it would have been less exposed to water and not cracked, just a guess though.
The 5k cracked but I wouldn't seal that.
They function fine with the cracks either way.

I think in the past I used to soak the 5k but I cannot recall of I soaked the 10k.
I use plastic spray in a can, quick n easy, 2 coats.
Expensive jnats I use urushi.
