I ordered the wood for my staircase and now I need to decide on which product to use.
Some people recomened polyurethane or some water base resin, but I don't like that (I think it might crack and/or scratch).
Apart from that there are some varnishes available that are meant to protect from sun/water with guarantee of 3-5 years.
I'm also considering using some kind of oil/wax, but in Brazil finish oils are hard to come by. I think that I might find mineral oil, carnauba wax and bee wax.
The wood I'm using is rated at about 1750 pounds-force on the Janka scale, should I be worried about the wood getting damaged by constant walking?
