Question 1

Suitable for an edge-grain/flat-grain/quartersawn kitchen countertop with undermount sink? can it be waterproofed somehow?

Accepted Answer

I mill my trees and created a walnut coffee table whereupon I used Osmo to seal the wood.  So far it has worked.  My wife even brings her soup/cocoa to set upon the table as she watches the tube.  However, I am not certain Osmo would be good to use on a kitchen countertop.  Better to use Stone Coat Epoxy or some of the bar top epoxies available at Lowes or Home Depot.  And in order to achieve a satin finish after using a "glassy" bar top epoxy, you simple sand the top with 320 - 600 grit sandpaper in an orbital sander to achieve the satin finish.

Question 2

I just did 2 coats on my unfinished tabletop and bookshelves, is it pointless for applying a 3rd coat? or 2 coats are already enough. Thank you.

Accepted Answer

If you're using the Extra Thin Osmo (as pictured in the photo), then, I suggest using a 3rd coat, at least.  That would provide better protection for the surfaces.  Now, if you're using a thicker Osmo, 2 coats MIGHT do the trick.  
I make lazy susans and here's my scheme:
• start with 1 coat of Extra Thin Osmo Oil
• apply a 2nd coat, but this time use regular viscosity Osmo.  I always have 2 coats (at least) on the bottom of products
• for the top surface, I start with Extra Thin for first coat, then apply at least 2 more coats of regular viscosity Osmo Oil.
I apply each coat by rubbing vigorously with a rather non-abrasive Scotch-Brite type pad (high grit).  Then, I wait 6-8 minutes to let Osmo sink in and/or dry a bit.  When I rub it off, I use pieces of cut-up t-shirt that are cut into squares, always trying to wipe with a clean surface (it just comes off better if the spot is clean).  After I have the surface wiped off until no more comes off onto the rag, I then set that piece aside to dry overnight.  And, yes, I do this for each coat, regardless of viscosity.
After I have 3 coats (minimum) on the top surface, I evaluate after the surface has dried completely.  If I feel like it needs another coat, I apply that.  Otherwise, I just go with it.
And, on SOME items, I will apply a coat of paste wax (I used Johnson's wax), let that dry, then buff it off with a motorized hand buffer (sheepskin pad) or else just a good buffing with clean cloth.  That seems to help make the top surface really nice and smooth.

I hope this helps.  I've used this process on about 50 lazy susans so far and plan to continue doing so.

Question 3

Seems like this can be applied on top of Osmo Top Oil?
