INSTALLATION
RECOMMENDATIONS
Quick Set Lite Compound may
be used for finishing joints
on exterior soffit board and
gypsum panel products in
sheltered exterior ceiling
and soffit areas. It is not
recommended for use in
exterior application on walls.
Intallation of Quick Set Lite
should be consistent with
methods described in the noted
standards and references and as
indicated below.
In cold water (outside temperature
below 50°F [10°C]), temper-
atures within the building
should be maintained at a
minimum 50°F (10°C), both
day and night, during joint
finishing. Adequate ventilation
should be provided to eliminate
excess moisture.
Conventional Taping
And Finishing
Taping: Fill joint and embed tape
simultaneously. All flat gypsum
board joints are to be filled and
taped in one operation with
Quick Set Lite, using ProForm
®
brand Paper Tape in the
conventional manner. When
ProForm
®
brand Fiberglass Mesh
Tape is used, it is firmly pressed
to the gypsum board, spanning
the joints. Quick Site Lite is
then immediately applied to the
joints. The compound must be
forced through the tape to fill
the joint.
All inside corners may be
taped using appropriate joint
compounds. Quick Set Lite
may be used for the first coat
on nail or screw heads and will
decrease problems with fastener
imperfections. If a two-trip
application method is desired,
Quick Set Lite may also be used
for the first coat on cornerbead
and for taping inside corners.
First finishing coat: As soon as
Quick Set Lite used for taping
has hardened, the first finishing
coat may be applied on the
flat joints even before they
are dry. Any joint compound
may be used for this operation,
including Quck Set Lite and
ProForm Ready Mix Joint
Compounds. A second coat
may be applied at this time
to nail or screw heads; one
coat on one side of the inside
corners and a second coat on
cornerbead if Quick Set Lite
was used for the first coat.
Second finishing coat: As soon
as the Quick Set Lite used for
the previous steps has set, or
the ready mix compound has
thoroughly dried, a second
finishing coat is applied to all
joints. A third coat is applied
over nail or screw heads and on
cornerbead as required. The
unfinished side of the inside
corners is also finished at this
time.
Taping And Finishing With
Mechanical Tools
Taping: Taping tools, such as the
“banjo” and “hopper” types,
are recommended for taping
the flat joints with Quick Set
Lite and the inside corners
with regular or Quick Set
Lite. Automatic taping tools
are not recommended for use
with Quick Set Lite because
of the clean-up difficulties
associated with hardening-type
compounds. Mechanical tools
can be used for taping the
inside corners when a regular
joint compound is used. When
automatic taping tools are used
for taping the flat joints, the flat
joints and all space between the
gypum board edges on the butt
joints are prefilled with Quick
Set Lite and allowed to harden
(30 minutes longer than the set
time designated on the bag)
before taping with a regular
joint compound.
Finishing: Mechanical-type
finishing tools can be used
in the normal manner for
the finishing operations
since conventional finishing
compounds are used.
Concrete: Interior poured
concrete ceilings must be
properly prepared prior to
filling and finishing. Grind high
areas in concrete level with
surrounding areas. Remove
efflorescence, greasy deposits
and any form oil. Prime
exposed metal with quality rust-
inhibitive primer. Fill voids and
level offsets with Quick Set Lite.
Apply finishing coats of Quick
Set Lite as necessary after each
coat has hardened.
Mixing
Quick Set Lite is available in 5,
20, 45, 90 and 210 minute set
times. Mix no more compound
than can be applied in the
designated set time. A plastic
container is recommended
because of its ease in cleaning
between batches. Do not use
a wood or aluminum bucket.
Add the compound gradually to
clean water while stirring. Use
only fresh, clean water suitable
for human consumption. Mix
at the ratio of 11-12 pints (5.2-
5.7 L) of water to the 18 lb.
(8.2 kg) bag. Mix the
compound free of lumps with
a mechanical mixer or by
hand. Mechanical mixing is
recommended. Allow to stand
as a “wetting” period and
remix to further improve the
working qualities. If a slightly
thinner or thicker compound is
desired after mixing, add water
or powder sparingly. Close
opened bag as tight as possible
or setting time may be affected.
• High-speed mixing or excessive
mixing will shorten the working
time.
• Do not add water or remix after
compound begins to thicken
and harden.
STORAGE
Storage life in high humidity area
is 6 months; other areas, up to
12 months maximum.
