Just doing some research on some Acacia today and while reading through a few guidelines on the subject posted I found utterly ridiculous "suggestions" about acclimating in the package - what does that do for hardwood and moisture content - nothing.
Another said if the wood inside the box is wrapped in plastic you are to simply cut open the ends of the box, remove the plastic on the ends and let it sit for a week. This only makes the wood shrink at the ends causing an unfortunate installation nightmare and more gaps than you can shake a stick at.
I would suppose "not taking the wood out of the box" is ok if the ambient temp and rh match the moisture content of the hardwood, but really how often does that happen? Certainly not out here in the southwest.

Yet another said engineered does not need to be acclimated at all. Simply stunning revelations of these supposed wood experts out there selling wood floors with no idea what they are saying.

It all comes down to common sense and science - some have it, some don't - some read it and some just don't give a fig.

Thanks for listening to my rant. :mrgreen:

It's different everywhere. I'm sure glad we have you around for the arid desert knowledge.

Didn't you know everyone is an expert?

Thanks Ken.

One other thing about here and low/high MC values is if the woods at 9 - 10 and like here I strive for a 7-7.5ish - if I try and dry it down to much it warps and bows making the installation a nightmare.

Yes, the moisture control is very improtant to control the movement of acacia solid wood plank after installation.

When we do export to US, the big importer require second drying process for raw acacia wood to drop the around 10%.

Some manufacture just ignore it, the problem will comes after insalltion.

Excessive drying will be also a problem,as more acacia raw plank will shrink & crack, factory suffer more loss on raw wood, cost rised.

So never expect the wood dried to 8%-9%, really not realistic!

Thanks for that tidbit of wisdom leootau. And 10% is way to high for arid regions. Makes me woner why it's even sold out here. I know of one distributor who pulled all their acacia sample out of the entire state due to high claims. I still see it from others though.

Interesting and helpful.

I have some Acacia, not yet installed, that is measuring between 8.0 and 9.3 moisture content. That seems wet given the current temperature and humidity.

The Acacia has been out of the boxes and cross stacked for a week.
The meter is a Delmhorst J-2000.
Species setting specified and verified by Delmohrst (Douglas Fir).
Temperature setting is 65 degrees F.
Measured ambient temperature is 65 degrees F.
Relative humidity is 33%.
I think EMC for these conditions is about 6.8.

You may want to take your moisture meter with you if you plan to purchase Acacia.
