I will be installing Mirage 1/2" thick, 5" wide, Mirage Maple Engineered floor over 3/4" OSB Subfloor.

I've read that for 5" wide it is a good idea to both nail and glue. The flooring is expensive so I don't mind spending a bit more on glue if it will make it more solid and less likely to squeak later.

My questions are (assuming it does make sense to both glue and nail):

how much glue is needed? I've seen examples where a snake pattern bead is applied to the back of the floor before it is set in place and nailed.

Do I need a moisture underlayment? It seems is though that would not be ideal if I am using glue as wouldn't I want the glue to be connecting the OSB and flooring?

Thanks for any help you can provide.

What's the manufacturer's install directions say?
Follow there directions to the letter or there's no warranty.

They say do one or the other but not both. I will check with them that doing both does not void the warranty.

Their own instructions say - if you nail the boards may move and creak. So they don't really provide a satisfactory solution.

I am looking for advice on what would be the most ideal and then I will check with them that it does not void the warranty. My assumption is that it would be better than what they have in their guides.

"My assumption is" and lastly "never assume anything" and you will never get in trouble.
