We have polyurethane covered hardwood floors thruoghout our home, and after 15 years they still look great!
However, I read about "Marine Spar Urethane" being better for horse stalls. But I also read thet it needs to be redone more often, because it is more "flexible" to withstand temperature changes. I am located in south-central Pennsylvania so we do have wide temperature changes.
Any suggestions for staining and finishing wood for stalls? By the way, I am planning on getting 2X6 white pine tounge and groove.
