Hatteras products made with cumaru wood have no varnish on them. Can I apply a finish of my own?
You don’t have to, but you certainly can if you want! Cumaru will hold varnish just fine, but the South American hardwood is so naturally tough, and when left unfinished, ages to a lovely silver-gray, that we treat ours only with a mild conditioning oil. If you decide to apply varnish to the spreader bar of a Hatteras Hammock or Hatteras Single Cushioned Swing, take particular care in protecting any adjacent rope; wrapping the rope in quality painter’s tape is advisable. We normally recommend 24 hours for drying after refinishing, but cumaru is remarkable in part for being so hard and nonabsorbent, so it may take a while longer for the varnish to completely set.
