How long does it take for wood to warp?
Applying an end sealer to the boards will reduce splitting. Properly stacked lumber dries quickly in warm, dry weather. Softwoods like pine and cedar will air dry to suitable moisture content in as little as 6 weeks during the spring and summer months. Hardwoods like Maple, Oak, and Walnut will dry in 6 -12 months.
Will finished wood warp?
It will warp or not warp totally independent of how it’s finished, because a finish only slows moisture exchange. It doesn’t stop it. Both sides of the board will adjust reasonably rapidly whether they’re finished or not.
Will warped wood go back to normal?

Can you straighten twisted wood?
To straighten warped wood, I soak in water. Or if you can’t submerse them put a wet cloth on the inside of the warp curve, and soak until straight.
