   good point. I back prime all wood...interior and exterior.

   my experience is that wood floors have a vapor barrier installed under them..though it would be difficult to make the case that the vapor barrier is as effective as a back prime.

   why isn't wood strip flooring back primed before install, to seal out moisture & reduce the amount of seasonal expansion / contraction ???

   *Wood strip flooring is typically very stable and kiln dried. It is typically used in interior installations where it is not exposed to the ravages of weather. Seasonal expansion and contraction is normal and back sealing would do very little to eliminate this. Even siding that is back primed suffers from seasional movement, it is just not apparent since the tolerances are much greater than flooring.

   wood flooring is at a level in the house that moisture should not be anyway, think of it as carpet, do you prime the carpet or make it water resistant in any way? Expansion and contraction will come into play anyplace in the structure, its natural and will happen...hopefully at the same rate as the subfloor, and will not matter. But if moisture is the main concerne here, a remedy below the subfloor is what needs to be found.
