Topic tags/keywords: question walnut sander finishing rustic

Greetings!
I’ve just finished the final sanding (I used 220 grit) of two beautiful slabs of black walnut that I’m going to use to make dining table benches out of. I’m concered that I use the best top coat that I can. I was planning on using a gloss poly (water based). I’m still a rookie woodworker and I really don’t want to screw this up. Suggestions please. How many coats, type of brush, etc. Thank you!

Walnut tends to have a coarse grain, so if you want it like glass, you might have to use a grain filler. I would use 3 coats of poly, and sand lightly between coats. I would use the oil based poly however. It just wears better. Also, use a good brush. I like the Purdy brushes.

I think water based poly will work fine for you in this application. Wayne is probably right about the oil based wearing better over time, but I don’t think it is too significant a difference. I have had my best results applying it with a foam brush. Probably three coats, with very light sanding between.

Walnut is my wood of choice when it comes to a project for the home. The finish schedule that I use on walnut is 4 or more coats of orange shallac, then wet sand with 1000 grit and mineral oil, let cure for 24 hours then start with oil based poly usually 3 coats with light wet sanding inbetween coats. If you decide to use this make sure to use dewaxed shallac if you use oil based poly. I don’t know if the world would end if you didn’t but that is what all the pro’s say and I figure they know more than me. Oh if you want to see how the finish looks all my projects posted here with walnut have this finish schedule.
