Drying intracellular v. intercellular moisture

Lyndenbrook Farm · Nov 22, 2014

I know the question I have has likely been answered, but my searched has not revealed where it lurks ...

My question is whether it takes longer to dry the intracellular moisture of green wood than intercellular moisture. I have seen it referred to also as "bound" and "free" moisture, respectively.

In other words, if I have seasoned wood that got a little damp with MC of X% on the open side, that should dry out a lot faster than green wood also with MC of X%. Right?

Am I making sense? (Cuz that would be unusual, for me)

I don't think your premise is sound. Wood that is seasoned and then gets wet won't absorb much water in to the intracellular spaces. So, the wood won't have the same water content as unseasoned wood.

However, if such a thing happened, then I think the intracellular water would dry up pretty quickly. if there is a way for water to quickly get into the wood, the same route would take the water out of the wood fairly quickly.

Free range water from external source will flash off quickly, Migration of captivated moisture in cells is a 2 - 3 year process for most dense hardwoods depending on your area's climatic conditions. Just because the external becomes re-wetted does not adversely affect the internal moisture migration useing good drying principals

So short answer then is is a little snowmelt dampens the ends, not a three-year drying time, yes?

Yes, rain or snow gets the outside of the wood wet, but doesn't soak very much. It dries off quickly.
