INSTALLATION
RECOMMENDATIONS
Installation of All Purpose Joint
Compound should be consis-
tent with methods described
in the noted standards and
references and as indicated
below.
All Purpose Joint Compound
may need a slight amount of
mixing before use, and in any
case should be lightly mixed
before any water is added.
Mixing may be done with a
potato-masher-type tool or by
useofalow-speeddrill.Use
directly from the container
for treating fasteners and
cornerbeads or for taping and
finishing joints. Care should be
taken when water is added to
thin to a desired consistency.
A uniformly thin layer of joint
compound should be applied
over the joint approximately
4" wide. The tape is then
centered over the joint and
embedded into the com-
pound, leaving sufficient joint
compound under the tape to
provide proper bond. A thin
coat of compound should
coverthetapetominimize
wrinkling or curling. Ceiling,
wall angles and inside corner
angles are reinforced with the
tape folded to conform to the
angle and embedded into the
compound.
After the compound is thor-
oughly dry (approximately
24 hours) the tape is covered
with a coat of all-purpose or
topping compound spread
over the tape approximately
3" on each edge. After this
coat is thoroughly dry, an-
other coat of all-purpose or
topping compound is applied
with a slight, uniform crown
over the joint. This coat should
be smooth and the edges
feathered approximately 3"
beyond the preceding coat.
All inside corners are coated
with at least two coats of
compound with the edges
feathered out.
All nail or screw head dimples
should receive three coats.
These coats may be applied
as each coat is applied to the
joints.
Flanges of gypsum board cor-
nerbead should be concealed
by at least two coats of com-
pound. The first coat should
be all-purpose compound
and the second coat can be
all-purpose or topping com-
pound feathered out approxi-
mately 9" on both sides of the
exposed metal nose.
In cold weather (outside tem-
perature below 50°F [10°C]),
temperatures within the build-
ing should be maintained at a
minimum 50°F (10°C), both
day and night, during joint
finishing. Adequate ventila-
tion should be provided to
eliminate excess moisture.
Wet/damp conditions slow the
drying process. Subsequently,
24 hours drying time between
coats may not be sufficient.
Adequate drying time is es-
sential to prevent unwanted
conditions such as cracks
from delayed shrinkage.
DECORATION
Before paint, wallcovering or
other decorating materials
are applied, all areas must be
thoroughly dry, dust free and
treated with a coat of good-
quality, high solids, flat latex
primer.
The selection of a paint to
give the specified or desired
finished characteristics is the
responsibility of the architect
or contractor.
Gypsum Association GA-214,
Recommended Specication
for Levels of Gypsum Board
Finish, should be referred
to in order to determine the
level of finishing needed to
assure a surface properly pre-
pared to accept the desired
decoration.

The chart above is a helpful guide in determining approximate drying times for
joint compounds under a variety of humidity/temperature conditions. Shaded
area is below the minimum application temperature requirement of 50° and is not
recommended for the application of joint compound.
