Anchorseal is used to seal the ends of logs from checking when harvested.

You can also use latex paint. The thinner it is the more likely to crack, leave it thick until dry then thin it down.

+1 Anchorseal.

+1 leave it thick while drying. General rule of thumb for air drying boards is 1 year per inch of thickness, but since this is all end grain it will dry faster (just not sure how much faster).

Personally, I prefer the color of air dried walnut to kiln dried. If this were my slab, I’d sticker it flat somewhere out of the way, cover it with old plywood or something similar let let it be for a few years. I think there is a good chance you will get some checking in that piece when fully dry. You definitely want it fully dried before you finish it or you will have adhesion problems and probably finish failure.

Call me crazy, but in this case the center is gone, and the “log” is very short. I think you could just leave it sitting around inside and it’ll dry fine in not much time. 6 months or so. Moisture transpiration in the direction of the grain will be pretty quick and with the center gone there won’t be much stress. Skip the anchorseal in this case (and I always use anchorseal, with this exception)
