What are the best compounds to use for drywall? I have been using joint compound for the first and second coats, one under the tape and one over. Then I use 45 minute hot mud. I am wondering if hot mud is O.K. to use for the second coat.
All comments welcome. Thanks.

Not a professional rocker but I always use 90 for tape coat and compound for proceeding coats.
It sounds to me like you have things upside-down. I'd use the setting compound first for it's strength and speed, followed by joint compound that can be sanded to a nice, smooth finished surface.

Lafarge- Rapid coat for all of it. Ready mixed in pails, very minimal shrinkage, sands easy, drys fast.
Youve let the saddle fall under the pony . Slider around back on top and cinch it up.
Hot mud first and finish coat of your choice . Do the build with hot mud .

I'm with Tim. Durabond, not the Easysand, for taping and beads. From there, it depends on the size of the job. If it's small and I want to be done now instead of standing around waiting, Easysand for the second coat. I like ProForm topping for the final. It sands super smooth. If it's really small like a patch, Durabond 20 for tape, drink a coffee, then Easy sand 5 a couple of times. Put a fan on it while you're at lunch. It'll be dried out enough to sand after an hour. I pretty much only use all purpose for thinning out and stomping ceilings.
But if you're not used to Durabond, (my bud Jim missed this critical element when I converted him) it doesn't sand for squat. So get it level and don't leave anything thinking you'll sand it later. I was getting cussed out the day he learned that one.

A lot of good comments here from others. Not sure how my technique will square up with others but my jobs come out very well.
LaFarge is excellent if you can get it where you are. Mostly I'm stuck with the green bucket Sheetrock mud. I always open the bucket, thin it down real good to where it is practically runny off the knife. Not watery, just very thin. I use that for the bed coat and hide coat. Then I use the blue bucket mud, thin it the same and get a nice smooth finish. Still have to sand (because I've yet to reach drywall mud Godhood yet) but not much and I never sand between coats. If you have slight ridges, all the better, they're your fill-in guide for the next coat.
Also I do the bed coat and hide coat all at once. That is, I bed the tape, then immediately do a top coat to it, the hide coat. Day 2 if I'm lucky which is 50/50, my second coat can very be my final finish coat with sanding on day 3.
For same day fix jobs, durabond is the absolutely way to go, followed by EasySand finish coat.
Depends on the job.
Small patch getitdonein one day things means I use all setting type easysand
middle sizerd where I am on the job all the time doing other stuff, I will use the bucket of premix exclusively.
But on full sized jobs, I use Durabond to set and cover, then easysand or premix to finish.
I have a finisher who uses stting type exclusively.

Thank you all for the great info.
I am curious what is the strongest material, Durabond sounds great but my taper says joint compound is better for the first and second coats because it is stronger. I'd love to use somthing else because that stuff takes forever to dry.
Thanks again you guys are great!
durabond is stronger than all purpose. I'd say test it, but it'd take you a week to get a sample built up out of all purpose that didn't crack on its own accord. Proof is in getting it off things it's dried on. Regular mud I can scrape off a paddle mixer with a knife. Durabond, I chuck the mixer into a workmate and go at it with an angle grinder and a wire wheel."The child is grown / The dream is gone / And I have become / Comfortably numb " lyrics by Roger Waters
I've been gone a week or so.
Your taper is full of it.
Durabond or almost any setting type mud is stronger and harder than premixed joint compound any day of the week and doesn't shrink up either.
You can prove it to yourself..

"I have a finisher that uses setting type exclusivley"
I suppose he is a hand finisher ?
I have often thought that would be a way that a hand finisher could compete to a degree. Really with a mesh taper that puts on fiber tape and a quick breakdown pump , he could at least allieviate a step. We have to mix up premix any way adding water to it. That would be a good system for scaffolding because of the loss of mobility . Or tall stilts for that matter.

Most of my work involves only a few rooms, barely enough for assembling or cleaning a bazooka.

How was your trip?
You missed my point . I figure you are in a rush to answer all that mail. :)

There's an excellent thread here about drywall mud:
