Do I need to sand plywood before gluing it with construction adhesive (http://www.homedepot.com/p/Loctite-PL-Premium-28-fl-oz-Polyurethane-Construction-Adhesive-1390594/202020474)? It's fresh out of Home Depot, has somewhat [uniformly] oily surface and strong smell. Is sanding it going to make the adhesion better, or that stuff is there specifically for the purpose of providing better adhesion?

Generally speaking no. If it's not as it should be you should return it and get your money back.

Not entirely true. Depending on what you're using it for and how you're binding it, there are different grades of plywood.
A/BB/X/WBP aren't necessarily going to bond well with one type of adhesive for a example so sanding might help in some circumstances.

>plywood should never need sanding
Then why do they sell "sanded plywood"?

Probably because it is sanded.
You don't sand plywood, because it's increadibly easy to sand through layers. If I remember correctly thay usually around 1-1,8 mm thick each.

I question that. I'm routinely using 60 grit on a power sander, and am yet to sand through a layer.
