Where do you cut drywall if you need to remove it but still want to easily put it back up?

I'll deviate from the other suggestions. I prefer to cut in open space and float new backing. It's more difficult to cut down a stud. The knife or saw can't penetrate cleanly through, and you tend to ...

Will joint compound / drywall mud clog my drain?

I think it would depend on the amount of compound you're putting down the drain, what size drain, how much water is used to flush the tools, and probably a few other factors I haven't thought of. ...

What is the best process for a first-timer doing a small drywall finishing job?

Paper tape or mesh tape? It comes down to preference. As a "beginner" (but not for long... haha) I feel that mesh tape will be easier for you. No, you do not have to use any special mud; premix will ...

meshed tape exposed on sanding

It's joint compound, commonly called mud, and not grout. If you are sanding into the tape, you have not applied enough. It's not a "one and done" product. You apply joint compound and embed ...

Voids under drywall tape unavoidable?

Under the tape, you should have no voids. If you do, you likely didn't press it into the bed of mud well enough, or you didn't have enough mud period. The mud acts like glue to the tape (properly ...

Where do you cut drywall if you need to remove it but still want to easily put it back up?

Find the screws with a magnet. Chip out the drywall compound in the screw-heads with a pick/nail/pointy-tool. Remove the screws. Cut the drywall down the middle of the stud.

It is hard to tell if your mix was even poor. I would guess it is but honestly you put the layer down so unevenly that it is hard to tell. If you say it was too dry then go with that - should have ...

Nope. It has to be done anyway or you'll have cracking. Some pro tapers prefill recessed joints anyway, then do their taping. Put it on and skim out nice and wide to conceal the hump. Such a joint ...
