Overheard a builder saying they'd let the glue tack up for 10 seconds and call it good

I was grabbing supplies at the lumberyard in Green Bay yesterday and heard a contractor tell his helper that 10 seconds was plenty of dry time for full spread wood glue. How long do you actually wait before you lay the boards down?

Depends on the glue. Titebond II needs like 30-60 seconds. But for regular old Elmer's? Yeah 10 seconds ain't gonna cut it.

Yeah but are you actually counting seconds or just guessing? Because I swear people say 30 seconds and it's more like a rushed 10 count in their head. Tested this on a shelf I built last week and Titebond II definitely got tacky faster than I expected but full hold took way longer. Like I clamped it for a full minute and still had some squeeze out. Does that clamping pressure matter more than the open time? Been wondering if I'm just bad at this or if there's actually a sweet spot between glue type and how hard you press.

lunakim I think you're onto something about the counting. I caught myself doing the same thing until I actually timed it with my phone. But here's an angle you might not have considered - the temperature of your shop matters a lot more than people talk about. If your glue or the wood is cold, that 30 second window can turn into 2 minutes easy. I had a project in my garage last winter where Titebond II sat open for almost 5 minutes before clamping and it still bonded fine. So maybe your open time is less about the glue type and more about what the thermostat says.
