I am getting close to completing a desk I am building. This has been a very ambitious project for me as this is the first time I have ever built any furniture (shelving not counted) and this is a height-adjustable sit/stand desk.
I am at a point where I want to start finishing the wood (which is Maple). I have access to a ton of Tung oil my dad picked up for dirt cheap. I also have some polyurethane. I want to seal the wood from water and give it a nice finish. My thoughts were I would use a few layers of Tung oil and then a layer or two of polyurethane.
I was talking to my dad today and he suggested that I use one or the other, but not both because tung oil is actually a finishing product and will seal the wood for me.
Is this true? Or does my original plan make sense? I am also open to suggestions. I believe he said he even had a bunch of linseed oil I could use.
