Butcherblock counter finish help - Osmo over waterlox?
I am leaning toward getting a DIY Walnut butcherblock countertop from craft art. They ship with one coat of waterlox, but i'd like to use Osmo. I got the impression that it's a bit easier to apply, and no so bad in the fume department. Could Osmo go right over the waterlox, or would it need to be sanded down first?
I recently read a post (can't find it now), that some people recommended some sort of epoxy around the sink area? Would Osmo alone not be enough protection? We not yet sure if our sink will be top mount or undermount, but i'd be most concerned with the exposed edge of countertop. If there is a reveal on the sink where water could pool, is Osmo, or even WL, enough protection?
Our other option might be a John Boos countertop and those come with a oiled finish, or a varnique (hard) finish . I know i'd have to sand down enough of an oil finish to make WL or Osmo work.
Any of you with wood countertops, do you need to maintain the underside at all to prevent drying?
