TIP
One bucket is for resting your
MudGun
™
to keep it clean and
free flowing for the duration of
the job. The other bucket is for
washing your hands and tools
and keeping rags damp.
TIP
There are many types of
drywall tape.
We recommend
using mesh or pre-scored
paper tape with this tool.

TAPING/FINIShING FULL RooMS
Taping a full room is best completed with a
MudGun
™
PRO
, which allows you
to bulk-load drywall compound directly from a 5-gallon bucket. You can also
adapt your
MudGun
™
Small Repairs
model for bulk-loading using a conversion
kit (HYDE
®
item #09630), available at the store where you purchased your
MudGun
™
or online at hydestore.com.
GETTING STARTEd
There are three types of joints to be taped: butt, tapered (manufactured) and
corner joints.
It’s best to tape your joints in the following order:
Butt joints are those that have the cut edges of two sheets of drywall meeting
each other. (A tapered edge meeting a cut edge is unacceptable, as it is not
possible to finish it properly.) When finished, a butt joint will not be flat. A slight
crown (outward bump) will result as you apply the tape and coats of mud over
an already flat surface.
Tape these joints first.
Tapered joints are those that have one wrapped, tapered edge of the drywall
meeting another tapered edge of drywall and are easiest to finish because
they will be flat after you fill the taper in the drywall (see illustration). Normally
on walls, tapered joints run horizontally because you can buy drywall sheets
in different lengths and create one long tapered joint with few or no butt joints
bisecting it vertically.
Tape these joints after the butt joints.
Corner joints are those that form a corner, such as where two walls meet or the
wall meets the ceiling. Like butt joints, corner joints won’t be flat or truly squared
when finished, since you’ll be adding tape and mud to surfaces that are already
flat. The goal with corner and butt joints is to cover the joint with a minimum
crown effect.
Tape your corners last.
