Engineered!!! Solid over concrete is risky and there is no room to cut any corners, or you will have a complete failure in short order. Also you being in dry arid Arizona, Engineered will not move as much as a solid will with just humidity changes.

Gluedown or floating is your choice. Gluedown has a more solid feel. Floating floors and hard sole shoes, get the clockedy, clockedy, sound. (hollow)

Thanks for your help, another question....any brand of the glue that everyone likes best? And is the glue the only moisture barrier that I will need or do we need the foam underlayment too?

For engineered gluedown, I love Taylor 2071. I believe they have a new adhesive, called M+S which is 2071, with a little extra secret sauce.

Wonderful, any idea where to purchase?

Didn't you guys just put down Taylor as not a good brand here?

Read the entire thread, jperryrocks.

Taylor is an excellent engineered adhesive. They even say it is great for solid wood. I personally would not use it for solid wood or bamboo, because I have seen end peaking(that eventually subsides) on engineered, which would translate into cupping on a solid board. They say it goes away, but I will not try it on a solid or a bamboo, personally. A moisture cure works for me with bamboo and solid.

I just re-read the whole thread and it didn't seem to be too positve of a tone about Taylor as a brand. Mostly it was about how to use the "right" products.

It's good to know that it's good to use for engineered.
