My guess is you have a bad meter..or you aren't using it correctly.

Just as important, have you acclimated the flooring to the atmosphere of the room for 72 hours yet? Is the heat and air conditioning operational and at a normal temperature. It won't matter how much moisture is in the wood, as long as the humidity of the room causes it. This will vary equally on all parts as the humidity changes and cracks, etc. should not be a problem.

Meter works good.

Yes the floor has acclimated in the room for over 2 weeks. House eat is working as naormal around 65-68 degrees

So I'm not sure with the 0% MC should I install??

It has acclimated, install it. Don't worry about the moisture. Sell the meter on Ebay. You're good to go.

And what do you get when you try it on various scrap pieces of wood other then red oak?

Yes. That is how a diagnoticians mind works!

Working with hardwoods years ago I thought we tried to achieve about 7% - but don't quote me.

If you have 0% for real, doesn't it have cracks? That sounds like an impossible number, unless it maybe laid out in the desert for a year.

found the problem, was not pushing the prongs far enough into the wood.

3/4" oak reading about 6.2 -6.5

3/4" plywood subfloor is 7.5 - 9.0

I think I'm good to go, correct????

Anyone else can confirm this???

You're relying too much on the moisture meter. Rely on proper methods. 72 hours of acclimation to the room regardless of the moisture content is the proper way to do it. But you can wait on other confirmation.

I can confirm my first guess was correct...lol...j/k.

As was said..if its been in the house with HVAC running for that long...its time to get to work and start installing it!

Chandler, sorry, but have to respectfully disagree....proper acclimation is ALL about moisture content...there is no set timeline.....unless you use moisture meters, there is no way to tell for sure that the floor is ready to be installed. You could buy flooring that they shipped across country on the back of a flat bed with little or no covering that has picked up a ton of moisture. Or you could buy flooring that was stored in the warehouse, stacked up underneath the air movers and is dry as a bone when you get it. In some instances, and with some species of wood, it may take a few weeks for the wood to fully acclimate.

You must check the moisture content in the subfloor and the hardwood. For hardwood 3" or narrower, the hardwood and subfloor should be within 4% of one another. For hardwood wider than 3", they should be within 2% of one another.

That being said, Hgy1243, you have a max difference of 2.8% (6.2-9.0), so if you're installing wood no wider than 3", you are good to go.
