STORAGE:
n Storage: Store off ground and protect from rain
and moisture.
n Shelf Life: Reference Parex USA Expiration Date of
Products Technical Bulletin.
SURFACE PREPARATION:
n The surface of the plaster “brown coat” base or
concrete partially determines the texture, color
and final result of the finish.
n After application of the brown coat rod, darby or
trowel it to produce the specified level.
n Next, hard float the brown coat to eliminate “slick
spots” and open the surface to enable a good
mechanical bond for the finish coat.
n Hand application over portland cement plaster:
Prior to application of exterior stucco finish, the
portland cement base coat shall be dampened
with clean water to control and equalize suction.
Allow surface moisture to dissipate prior to
application of the Exterior Stucco Color Coat. For
application over any surface other than a portland
cement plaster brown coat, contact Parex USA
Technical Support for proper preparation.
MIXING:
n Read the entire label before using this product.
n Using a mechanical plaster mixer, start with
approximately three gallons of cool, clean potable
water. Add one 90 lb. bag of Stucco Finish and
mix to a thin consistency until it is smooth and
free of lumps.
n Add all of the color packs (1 per bag for a standard
color, a maximum of 4 standard 1 lb. color packs can
be added per 90 lb. bag for increased color depth) to
be used for one “batch” and mix until color is evenly
dispersed, (approximately 1 to 2 minutes).
n Thin the mixture with water and then add the
remaining bags of stucco finish (adjusting water
as necessary) to correspond with the number of
color packs mixed as described abovce Allow
material to mix at a somewhat stiff consistency
for approximately 15 minutes. Add the remaining
amount of water to achieve the desired consistency,
and then disengage the mixing blades for
approximately 5 to 10 minutes in order to allow the
material to slake. Doing this allows the material
to start its initial set. Re-engage the mixing blades
for approximately 5 minutes, adjusting the water
and mixing only long enough to achieve uniformity.
The material is now ready to be removed from the
mixer and applied to the wall. (See Application
section.)
n For additional batches of the same material, thin the
remaining mixture with water, then repeat adding
the color packs and mixing as described. Wash out
mixer completely to change colors.
Note: All LaHabra cement/lime finish
products should be mechanically mixed
for a minimum of 20 minutes after the
last bag of stucco base is added to fully
disperse the color.
APPLICATION:
n Color coat shall be approximately 1/8” thick.
n Hand application over a portland cement plaster
brown coat: Prior to application of exterior stucco
finish, the portland cement base coat shall be
dampened with clean water to control and equalize
suction. Allow surface moisture to dissipate prior to
the application of the Stucco Finish.
n Standard (16/20) Sand Float finish:
Trowel apply an even coat completely covering the
base coat and sponge float the surface with circular
motions to the desired or approved finish level,
using as little water as possible.
n Standard (16/20) Skip Trowel textured finish:
Trowel or float apply an even coat completely
covering the base coat and sponge float the surface
with circular motions to a uniform float finish level.
Allow the first application-background to set,
although prior to drying out. Apply a small amount
of the same material over the floated background
using the skip trowel method to the desired finish
level then lightly trowel over the entire area,
“knocking it down” or lightly flattening it out,
using random strokes of the trowel.
n Fine Float (20/30) sand Float finish:
Trowel apply an even coat completely covering the
base coat and allow it to set, although prior to drying
out. Trowel apply a second tight coat of the same
material over the first and sponge float the surface
with circular motions to the desired or approved
finish level, using as little water as possible.
Machine application:
n Spray the first coat to completely cover the dry
portland cement brown coat.
n Correct imperfections by filling and/or scraping.
Allow to dry prior to applying the second texture coat.
n During periods of cool temperatures and/or high
humidity, it is recommended that one full day be
allowed between coats.
Note: Exterior Stucco Color Coat is not
designed for use as a smooth trowel
finish. Santa Barbara Mission Finish is the
product designed for this use.
