PM CONCENTRATE WR is
a factory blended, fiber reinforced, cement mixture
designed to be a highly water resistant cement plaster
base coat requiring only the addition of sand and water
on the job site. All components in the manufacturing
of PM CONCENTRATE WR meet the standards set forth in
ASTM C-926.
PM CONCENTRATE WR is
the product of choice when a superior, water resistant,
cement plaster base is desired. It has exceptional workability
and the fiber reinforcing strands greatly reduce the
possibility of cracking. PM CONCENTRATE
WR can be used for new construction and renovation
work.

PM CONCENTRATE WR is
packaged in 80 lb. bags and must be applied at a rate
not to exceed 60 - 80 square feet per bag at 3/8"
thick or 50 - 70 square feet per bag at 1/2"
thick. Coverage will vary due to application techniques
and substrate conditions.
Surfaces to be coated should be inspected by the contractor
and any unsatisfactory conditions should be reported
and corrected prior to the application of PM
CONCENTRATE WR. All flashings, hangers, fasteners,
trim or other fixed supports shown on the plans, should
be in place prior to application. Dust, dirt or loose
particles should be removed from concrete or masonry
surfaces prior to application. PM
CONCENTRATE WR should not be applied to surfaces
that contain frost. Provisions should be made to keep
PM CONCENTRATE WR at a
temperature of 45°F - 100°F during application
and for a period of at least 48 hours after application.
Adicote bonding agent must be applied to all poured
concrete or smooth concrete surfaces. Control and/or
expansion joints should be installed in accordance with
ASTM C-1063 to alleviate cracking from building component
movement, shrinkage or stress. Location of control joints
must be determined by the designer.
Measuring equal amounts of water and mixing for equal
amounts of time from batch to batch will ensure product
consistency from batch to batch. Use approximately 5 -
6 gallons of potable water and 180 - 220 lbs. of washed
plaster sand (ASTM C-897) per bag. Start the mixing process
by adding ? of the total required water to the mixer.
Add the appropriate amount of PM
CONCENTRATE WR, sand and then add the remaining
? of the required water. Mix for approximately 5 - 8 minutes
to bring the material to a workable consistency. Allow
the mix to set for 5 minutes, then remix and add additional
water if necessary to achieve the desired workable consistency.
Do not retemper the mix after this.
Note: The effectiveness
of PM CONCENTRATE WR depends
upon proper application, curing and the conditions and
preparation of the surface to which it is applied. Review
Application Guidelines for substrate conditions and
preparation. PM CONCENTRATE WR
should be applied to wire lath by sections to a minimum
of ½" thickness using sufficient pressure
to form a good bond.
NOTE:
To avoid abrupt changes in the uniform appearance of
the succeeding coats, PM CONCENTRATE
WR must be applied to an entire wall or ceiling
panel without interruptions.
The joining of wet product should be made at naturally
occurring interruptions such as corners, control joints,
or structure levels; otherwise, the stopping and starting
joints may be visible through the finish texture.
Reference Premix-Marbletite application instructions
entitled: "Base Coat Stucco Products" for
specific applications to selected substrates.
Moist cure by lightly fogging or misting for 48 hours
after application. Proper hydration requires sufficient
water, favorable temperatures and time. Newly installed
walls should be protected from hot/dry winds or excessive
ventilation. The temperature of the walls must be maintained
between 45°F - 100°F for no less than 48 hours
after application.

PM CONCENTRATE
WR is a cementitious product, and as such
cracking or efflorescence is not to be considered
a product defect and is not warrantable. |
|
If a texture is desired it must be
applied to the brown coat after the initial set
and prior to the final set. Do not apply texture
after final set has occurred. |
|
Due to the highly water repellant
nature of this product, cementitious stucco finishes
are not recommended for application to PM
CONCENTRATE WR. |
PM CONCENTRATE WR is
