Mixing
M
ix no more compound than can
be applied in the designated set
time. Place the amount of water
recommended on the compound
packaging in a clean 5-gallon pail.
A plastic container is recommended
because of its ease in cleaning
between batches. Add the com-
pound gradually to room tempera-
ture clean, drinkable water. Mix the
compound until it is smooth and
free of lumps. Allow to stand
(soak) for one minute, then remix
until consistency is smooth and
uniform. If a thinner or thicker mix
is desired, add water or powder
sparingly. When power mixing is
used, the motor speed should not
exceed 600 RPM since high speed
and prolonged mixing will shorten
the working time of the product.
Estimated
Working Times
One of the most crucial things for
selecting the proper ProForm
Quick Set Joint Compound is
matching its working time and
setting time ranges to the project.
It should be noted that working
time and setting time are not
the same.
Working Time refers to the
period during which the ProForm
Quick Set is usable for application.
At the end of this time, the material
begins to stiffen and can no longer
be spread easily. Working time
should correspond to the required
time for actual application.
Setting Time refers to the time
after which the applied ProForm
Quick Set Compound will become
adequately hardened so that
another layer can be applied. For
manufactured or modular builders,
the setting time should match your
timetable for moving a floor along
the line.

Limitations

N
ot to be applied over moist
surfaces or surfaces subject to
direct moisture.

Do not mix with any other
material. Use only clean, room
temperature, drinkable water.

Mixing equipment and tools
must be thoroughly cleaned
between batches.

Each fresh batch of compound
must be kept free of previous
batches; otherwise the working
time will be shortened.

High-speed mixing or excessive
mixing will shorten the working
time of the ProForm Quick Set
Compounds.

Do not add water or remix after
compound begins to thicken
and harden.

Cleanup difficulties with
automatic taping tools may
occur when using a setting-type
compound.

Close opened bag as tight as
possible for storage or setting
time may be affected.

Storage life in high humidity
area is 6 months; other areas up
to 12 months maximum.

In cold weather, temperatures
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.
Frequently Asked
Questions
1) Why is the product
lumpy after mixing?

Water was added to the ProForm
Quick Set, rather than the com-
p
ound being added to
the water.

ProForm Quick Set was not
allowed to soak (for approximately
one minute) after initial mix
before remixing was initiated.
2) Why is the product
setting much faster than
the advertised range?

Dirty mixing water and/or
application tools.

Excessive mixing of the
compound.

Foreign material (accidentally or
deliberately) added to the mixture.

Mixing water too hot.
3) Why is the product
setting much slower than
the advertised range?

Too much water was used.

Impure water source
(dissolved organics in the water
generally retard the set time).

Foreign material (accidentally or
deliberately) added to the mixture.

Water too cold.

Product was remixed after initial
stiffening began.
4) Why does the product
display weak strength?

Too much water was used.

Foreign material (accidentally or
deliberately) added to the mixture.
