It’s for my front door threshold, made of Sapele. I live in San Diego CA. The door is totally covered with a long shingled roof. It never gets direct sun. We almost never have driving rain. I doubt it ever got wet from the weather. I have some left over Waterlox original that’s just going to waste if I use it and it’s good for wear areas like my threshold. The door surround is mahogany covered with 5 coats of Penofin Penetrating Oil for hard wood, it’s been holding up fine for over a year. It looks great by the way. So my question: Can I expect it to be OK even though It’s technically “outside?

Call Waterlox; better-yet, e-mail your comment, and they will give it serious consideration – I’ve asked them a dozen questions, on a range of issues; and consistently I’ve gotten a considered response within 24 hours.

Waterlox melds into itself coat-over-coat; Waterlox Original is not a true finish – it’s a Sealer/Finish: no UV protection (which you probably don’t need). Ask the experts.

It’s probably fine… waterlox is both waterproof and temperature resistant. It won’t have much UV protection, but if there’s no direct sun I doubt this matters. And it does build over several coats to a good film.

Edit: I don’t know how flexible the finish is though… seasonal wood movement might probe problematic.

Great suggestion MJCD, I’ll do it. I’m agreeing with Bob but won’t hurt to give it a try.
