Question Humidity on its own can repair a crack?

A salesperson at my local (Kanata) Long + Mcquade gave me some advice: To permanently fix two small cracks on the top of a solid wood guitar top, place the guitar plus a couple of guitar humidifiers full of water, in its case for awhile. The high humidity could cause the wood to re-bond, ie meld back together.

So water is the new superglue. Should I patent this new miracle repair procedure?

No I did not make this up...any truth to it? I know wood would expand if saturated, but...

Well it can close the crack up (in fact humidifying is usually the first step in crack repair) but it can't permanently bond it, you need glue and possibly a cleat, for that.

Forgot to mention that he also said that they had a new guitar on the rack that developed a visible, long crack in the fretboard, but with lots of humidification the crack closed and they sold the guitar.

Absolutely Correct. Humidifying will CLOSE the crack but will not repair it. When the crack is closed squeeze some Titebond into the crack and make sure that it goes all the way through to the inside of the guitar. That repairs a small crack. Larger cracks require a cleat .

I was about to go drop 700+ on a new tube amp from them. Good to know cause now I'll find somewhere else.

Fleet pro sound is great, if Ian Weston is busy, Jeff McKay is a pretty reputable luthier

Ahh(sigh), as I hang my head. Overhumiifying will close a crack up temporarily, it also causes problems else where, paint lifting, braces separation etc

Please don’t.

You can close a crack by adding humidity. Next winter, when the humidity is low again, it will open back up. If you glue it and put on a cleat or three when it's closed it might not open up again. Maybe. I would not have much faith in that fingerboard.

I don’t think it would be ethical for you to apply for the patent since it was really the salesperson’s idea. 😂🤣😂
