You Betcha can!..I do it all the time..I use 3m spray mount adhesive, the water does not seem to bother it as long as it isnt soaking in it.
Thanks Ken,
What grit do you use. I was thinking as long as I am coarser than the grit of the stone I am ok. Right?
I use 220 grit, I havent had any problems...I keep my stones in a 5 gal bucket, made a cloth pouch that attaches to the outside to keep the plate nearby and handy. Whenever I pull a stone out or put back in it gets a quick rubdown with the plate.
Using sandpaper coarser than the stone you're flattening would probably make the process a little faster. The bond between the abrasive and the paper is stronger than the bond between the abrasive particles in the stone, so a finer grit also works, as Ken testifies. If you kept trying finer and finer sandpaper, I think you'd reach a point where the sandpaper wasn't toothy enough to grab and dislodge the particles from the stone.
You can flatten a deeply hollowed soft Japanese water stone with the wide show face of a breeze block (UK terminology) or cinder block (US terminology) in about 30 seconds. Breeze (cinder) blocks are usually remarkably flat, but do check the face with a straight edge before you go ahead. Slainte.
I use the mesh sandpaper which drywall guys use for wet sanding. It won't clog up and it's just the right size for a stone.

The rev,
I was going to suggest that but you beat me to it. It works great.

MT,
Got turned on to this waterstone challenge myself and was able to justify buying a large DMT diamond stone (actually bought several) and happily realized that the diamond stones worked great both to flatten the waterstones and to sharpen tools. Thus, I was able to dispose of the old cinder block which really now has no use and got in the way of my toes too often <g>. The diamond stones will probably soon replace my waterstones however thus making this point moot. Diamond stones seem to cut steel faster, better, and easier although I am still getting used to them. It is hard to teach an old dog new tricks and I am loath to stop using my 6000 grit King stone for the secondary bevel I try to achieve on plane and chisels.

I use a green stone, even though the rev's idea of a mesh drywall sanding sheet sounds like a winner. May try that myself.. The other ideas sound logical too. I suppose bottom line is if it works it ain't all that bad.
