you can do that, but like other people have said you want it to be a little thinner.

Try to sand a lot of what you already have up down smooth, then tape all the corners. Youtube is your friend.

Then do a SUPER LIGHT coat on top of your tape. Then a SUPER LIGHT sand.

By this point you should be almost smooth. if you need another coat, go for it. Light, thin coats are the way. Heck, if it takes you 4 coats, go for it. Slowly get smoother and smoother until you are happy.

Step one would have been not to have huge gaps in the corners tbh...

The job starts with hanging the drywall. The cheat is to use Great Stuff to fill gaps, use a filet knife to cut it flush and move straight to tape and compound...

But that's in the past.

You need to sand the highspots until your either flat or to the paper. Then start from there with tape and compound.

YouTube has lots of videos that make it look easy. It won't be, but with a few extra hours of sanding you'll still be successful.

Also, forget hot mud. It's hard to even know how much strength hot mud provides, it's more about working speed which isn't your concern. Premix is way more forgiving

Remember that a bunch of very thin coats is better than one big fat coat Use the flex in the widest knife you can to keep it thin. It takes practice, it's not an easy skill until you learn it.

If the gaps are big it’s best to get something more solid in there for backing before taping. I can’t tell how big they are, but if the gaps are like 1/2 inch or more I’d just cut some strips from some of your drywall waste and fill those gaps as best you can. Then, tape.

A little mud goes a long ways. It’s easier to add more thin coats, than it is having to sand down thick coats. When I did my bathroom I ended up doing 3 coats, starting with 6 inch blade, then 8 then 12. Then I sanded most off cause it was too thick, and did the same process but with much thinner coats. Light sanding between coats. Turned out good.

I hated it so much though that I have hired a pro for every mud job big or small since then 😂
