I am commissioned to build a staircase and landing out pf 4” thick Beetle kill pine. My only concern is that pine being soft will wear down faster when being walked on. Would Coating the surfaces with a wood hardener or stabilizer help or not? Kind of a marquis project and I want it right. Cutting big trees for this.
Side note; using polyurethane designed for flooring to finish it. Maybe that’s enough?
