Next, wet and swipe the empty blade at a 23-degree angle lengthwise
along the mud strip to smooth the mud, feather the edges and cover
the joint. Why a wet blade? So it won't grab and make
holes in the mud track, like over-stretched dough. Saves time and
mud refill later.
Tear
off drywall tape to fit mud track length and wet it in bucket of water. Slide tape through your
fingers like rollers to remove excess water. Lay tape on the mud,
so the joint underneath is under the middle of the tape.
With empty blade (no need wet) tilted at 23-degree angle, lightly smooth tape
lengthwise into mud track.

Load the blade with mud and swipe mud crosswise across the tape, as
before, to cover tape. Keep mud track narrow as before to
make feathering easier.
Wet
and swipe
empty blade at about 23-degrees lengthwise along mud track, as
before,
feathering edges. Then repeat entire process
along bare joints again. Allow to dry. Then sand--who'd have
thought?--drywall panels have a grain, lengthwise, so sand in
longwise direction of panel for smoothest results. A quick
sanding tool is to get "screen" drywall sanding strips on a swivel head
with long mop-style handle, to reach high spots. Both hands apply and
control pressure, two passes are usually enough. The screen
strips flip over, and change fast on the swivel head's butterfly
clamps. More
mud fill needed? Do an overcoat, use a wider blade,
add a light coat of mud
crosswise, then lengthwise, as before. Allow to dry, then sand
with the grain again. Once you are satisfied with the surface
flatness, paint with primer, then your desired color.
That's it! Next up, how to do corners.
