I just bought my prefinished 3/4" red oak hardwood, just put it in the room where it will be installed a week later.

Question: this room is humid, is there any danger that this prefinished wood will warp? Someone told me that it behaves differently than unfinished wood.. Sorry if this is a stupid question....

professionals test & know the exact moisture content of the wood & the subfloor & the air. do you have any moisture meters? if you don't, you're heading for trouble. www.nofma.org has all kinds of info on wood flooring, as does this site. search the words "moisture content" in this topic & you'll find some answers. i think the humidity needs to be between a certain level (55%) and the wood has to have no more than a certain amount, or all heck breaks loose. cupping, warping, swelling, gaps forming later.........yikes. it also depends on the width of your planks. wider planks are in more danger than skinny ones.

i'll try to find some past threads on this..........

If the area has higher humidity then normal and you can't keep it somewhat consistent, then acclimation is not going to be happening.

Acclimating in high humidity will swell the boards. You install them and the humidity goes down, after you get in and turn on the heater or A/C. Now you have a gapped floor because the boards shrank.

If I install when the boards are acclimitized when it is humid, then later there are gaps.

If I install when the boards are acclimitized to dry, then later there is danger of the boards bowing.

My idea is to acclimitze them to humid, install it tightly and know they will not buckle or bow during a humid summer and accept the shrinkage in the winter. I will artificially humidify a room where they can acclimitize to it over a week, not going over 55%.

Is there a better way?

Yes, there is a better way. All your doing is guessing. Guessing will get you in big trouble, either way on the scale.

What moisture meter and hygrometer have you chosen, to perform the experiment?
