Installing prefinished 5/8" bamboo in a dining room / kitchen using hidden-nail method.
It occurred to me that I might get better moisture resistance against unexpected spills/splashes/water if I sealed the tongue-in-groove by applying a waterproof wood glue to the tongues before installation. (The finished edges have a microbevel)

If I am willing to go to this trouble, is there any reason why I would NOT want to do it. The floor will expand/contract with temperature and humidity even if don't do it, so it seems like it could only minimize that sort of problem.

Opinions ?
Thanks !

No opinions on this ?
Does that mean no objections ? It seems like a question that would have come up before, but I couldn't find anything using the SEARCH feature.

Thanks

Don't do it.

I would not do it either. Even though it is not a true solid in my mind, the boards still need to move uninhibited.

Thanks for the replies.
Obviously, I would like to include SOME method of sealing the joints.
When any "normal" wood floor is finished after installation, the polyurethane seals joints and the boards can't move much independently without cracking the finish; so why would a thin layer of waterproof glue (if a slightly flexible type, like Titebond) be much different ?

Have any of you actually tried any similar schemes with bad (or good) results ?

Thanks.

No, I've not tried it. I have read where trying to glue together solids is an effort in futility and not wise either. After a few seasonal changes site-finished floors expand and contract and the original seal is broken. The finish does not crack though. I do think a site-finished floor is more apt to withstand a little more water "accidents" than a prefinished.

Bamboo needs to have it's own classification as it is not a wood and not a true solid either. I tend to always follow a manufacturers instructions on putting their product down.

Jerry, look at the side edges of the boards in an OMU finished, under magnification, after a year of seasonal movement. You may recant that the finish doesn't crack.

Waterbased stretches, and is why white lines are seen along the edges, when a floor moves.
