GREAT STUFF PRO Construction Adhesive for Wall & Floor 26.5oz, Polyurethane Foam Adhesive for Subfloors, Drywall & Foam Panels, One Component, Off White, Pack of 12 with Applicator (Standard Gun)

I've never used this before but watching videos taught me alot, and even I, a novice, had no problems using it. And following directions, it laid down a nice even flow on the subfloor joist we are installing

Easy to apply, and just keeps going... I just finished laying 850sqft of subfloor and it only took 3 cans. Very strong glue as well. one day later and the bond can't be broken. I hope it holds that well for life. I'm not expecting squeaky floors in my future.Very happy with this product.

Complaint is more about the gun. Used the first few cans with no problem, ran the cleaner through it that night, next day it wouldn’t work. Ran more cleaner through it, changed cans, still wouldn’t work. Great when it worked, but expensive when it doesn’t.

Use it daily building houses. no more liquid nail for our company. We use only great stuff products.
