LIMITATIONS
Storage
• Shelf life up to 9 months under good storage conditions
(see production code date).
• Maintain temperature at a minimum 50°F (10°C) and protect
container from exposure to extreme heat and sunlight to prevent
spoilage and freezing.
Frozen Ready Mix
• Allow material to thaw at room temperature for at least 24 hours.
• Once thawed, turn the container upside-down for at least 15 minutes.
• Turn pail right side up, remove lid and immediately remix with an
electric drill.
• Ready mix should be lump free and ready to use within 1 minute.
• Discard all ready mix that does not remix to a lump-free consistency.
Stacking
Do not stack ready mix pails or cartons more than two pallets in height.
General
• Do not overthin ready mix.
• Do not overmix with an electric drill. This can cause undesirable
changes in viscosity and in the nished surface appearance.
HANDLING AND PROJECT CONDITIONS
Environmental Conditions
Varying weather conditions can impact both the quality and appearance
of taped gypsum board joints. Relative humidity, plus temperature,
will aect the working characteristics of all joint compounds.
Minimize the potential for nishing and decorating problems when
temperature, humidity and airow remain constant and as close
to occupancy environmental conditions as possible. Continuously
maintain a minimum temperature of 50°F (10°C) for 48 hours prior
to and throughout the nishing process until applied materials are
thoroughly dry.
For example, cool, wet weather will slow down the drying process while
hot, dry weather hastens the drying process. Exposure to winds,
breezes or drafts while drying can also aect the performance of joint
compounds. Typical problems from improper drying can be cracking,
excessive shrinkage, ridging and beading, banding or bond failure. A
further explanation of these conditions is outlined in the “Problems And
Solutions” section of the ProForm® Finishing Products Construction Guide.
Always take proper precautions at the jobsite to minimize the adverse
eects of weather on drying. These precautions will ultimately reduce
the application time and expense from callbacks and rework.
Planning And Prevention: Mold And Mildew Resistance
Planning and prevention is the most eective way to avert the growth
of mold or mildew. Deliver gypsum board and nishing products
to a jobsite as near to the time they will be used as possible. Once
delivered to a jobsite, place gypsum board under cover immediately
and properly protect it. Do not expose it to outside elements, such
as rain, snow or other high moisture conditions. If building materials
get wet from any moisture source, identify and correct that source.
If mold or mildew growth occurs, or if you suspect it might occur
due to environmental conditions and moisture, either attempt to dry
and clean the aected areas or replace the aected materials. If you
do not have the training or experience to recognize and to make the
proper decisions about repair or removal, consult a professional. A
proper evaluation must be made.
No material can be considered “mold-proof,” nor is it certain that
any material will resist mold or mildew indenitely. When used in
conjunction with good design, handling and construction practices,
ProForm joint compound can provide increased mold resistance. As
with any building material, avoid water exposure during handling,
storage, installation and after installation is complete. This is the best
way to avoid the formation of mold or mildew.
