    I have a slight warp/curve in a tabletop I'm refinishing. My wonderful and brilliant husband said I could wet the tabletop on both sides and clamp it between 2 boards. Is this true?

    Yep, the hubby's right. You may have to do it a bunch of times before the wood fully accepts its straightening, but it works and is done everyday.

    How do you straighten hard wood that is 1/4th of an inch thick?
    Community Answer
    I think only steaming/ironing is your only hope for that thinner stuff. Or, install it damp and with finish screws instead of nails and you'll be perfectly fine.

    Do any of these three methods work for GAF composite 2x4 or 1x10 deck lumber?
    Community Answer
    I doubt these exact methods would work, due to the amount of plastic in the composite. However, heat would be your best bet. Try wrapping black trash bags around the lumber and setting it in the sun.

    Does the wood have to be raw when unwarping it?
    Community Answer
    A finish will keep the moisture from entering the cells in the grain, even when sanded to one degree or another. Heat and pressure methods shouldn't be affected by a coating though.
