Old guy on a crew in Denver taught me about mud consistency

Tbh I was mixing my joint compound way too thin for years. Guy named Frank on a job in Denver grabbed my pan and said 'it should hold a peak, not run off the knife.' He showed me how to add a little powder back in and stir it slower. Has anyone else had an old timer call them out on something basic like that?

Oh man, that mud consistency thing is so real. I actually heard somewhere that the perfect joint compound should be like a really thick milkshake or mayo - not watery at all. I mean, I used to mix mine way too wet too, like practically dripping off the knife, and wondered why everything was sagging or cracking. It makes total sense that it needs to hold a peak, you want it to stick where you put it, not slide all over the place. Frank sounds like a legend for showing you that trick, those little tips from experienced people are worth more than any YouTube tutorial.

Have you tried using a 5-in-1 tool to check your mud consistency instead of just eyeballing it? I started doing that after I messed up a whole batch and had to scrape it all off. You want the mud to hold a stiff peak when you dab it, not slouch over like a soft serve cone after a few seconds. For the first coat over tape, I actually keep it a little looser like taylorlewis said, but not watery - think pancake batter thick. The trick is to mix it dry first, then add water a splash at a time while you stir, so you don't overshoot. Once you get that feel down, it's way less likely to sag or crack on you. Frank's tip about testing peaks is solid, that's how you know it'll stick without fighting you the whole time.

Nah, I gotta disagree a bit. Thick milkshake consistency works for some things but not everything. If you're doing a first coat over mesh tape or filling big gaps, you actually want it a little looser so it can really get into the gaps and not leave air pockets. I've had more issues with mud that was too thick leaving tiny voids that turn into cracks later. For the final skim coat though, yeah, you want it stiffer. But that one-size-fits-all approach to mud consistency is a trap.
