To finish an inside corner. They make a trowel
for mudding inside corners, but it isn't a necessity.

I suggest paper tape and not mesh. Mesh is for
a handyman, if you're going to do it, you may as
well learn right.

First roll out enough tape to go from clg to floor
tear it off and fold it lengthwise down the center.

Apply a thin layer of mud to each side of the
corner, coming out a few inches. Place the tape in
the corner and run a mud knife down the length pressing
the tape into the mud. You have to be careful not
to press so hard that you squeeze all the mud out from
under the tape or the tape will bubble. If it bubbles
or you encounter other problems I suggest you remove it
and scrape the mud off while its still wet and start over.
Don't expect it to look good at this point. You can apply
a coat of mud over the tape at this time, but I would suggest
waiting if it's your first try. Wait 2 day and apply you next
coat of mud over the tape and smooth top to bottom.
Another tip for first timers is only do one side
of a corner wait 2 days and do the other side. After
2 days smooth the first coat with sandpaper(very messy)
or scraping with your mud knife, or wipe with a damp sponge.
Continue doing this for minimum 3 coats of mud. First
timers be glad if you finish with 5 or 6 coats.
It's better to put to little each coat than over
do it and have to sand it alot.

Outside corners use a metal corner bead and tape
each edge of the corner bead, one tape strip to each
side of the bead.
