What about a polyurethane finish that isn't "grippy"? Do you have an opinion about any type of polyurethane finish, i.e., Bona Traffic WaterBorne, that might work? It appears that many ballroom dance floors have some type of polyurethane finish and still provide a good surface for dancing that isn't too sticky or "grippy". Thanks.
I understand your concern . But I don't think many of the finishes on the market will give you "grip" issues. I've used satin oil , semi gloss oil and high gloss oil on dance floors. I've also used satin traffic. None of them were particularly slippery or grippy. But satin will feel less sticky than gloss will.
For instance, in the guitar industry , satin finishes on guitar necks feel much more silky than gloss finishes do.The same applies to floors. So go with a satin finish but be concerned about durability.Bona traffic is much harder than any oil based urethane and will take a lot more abuse.
