PRODUCT DATASHEET
DESCRIPTION: Rapid Set
®
STUCCO MIX is a premium blend of Rapid Set
®
Cement,
quality plaster sand, and high performance additives for use in exterior plastering and
stucco applications. STUCCO MIX is ideal where fast turnaround, high strength, superior
durability, minimal shrinkage, and reduced cracking are desired. The appearance is
similar to portland cement-based plaster and may be applied using like methods. Just
add water. STUCCO MIX carries a current ICC-ES Evaluation Report (ESR-2671).
USES: Use STUCCO MIX for installation over masonry, concrete, berboard, gypsum,
wood or cement-based sheathing. STUCCO MIX may be used as the scratch and brown
coats in conventional 3-coat applications, or as the base coat in one-coat applications.
ENVIRONMENTAL ADVANTAGES: Use STUCCO MIX to reduce your carbon footprint
and lower the environmental impact of a project. Production of Rapid Set cement emits
far less CO
2
than portland cement. Contact your representative for LEED values and
environmental information.
APPLICATION: Apply STUCCO MIX using traditional means and methods. STUCCO MIX
can be applied from 3/8" to 2" (1.0 cm to 5.1 cm) in thickness. Apply by hand (trowel)
or by machine. Projects using STUCCO MIX must follow conventional methods, comply
with applicable building codes and ICC-ES Report ESR-2671. See CTS specication and
application guidelines available at www.CTScement.com.
SURFACE PREPARATION: For repair projects, application surface must be clean, sound
and free from any materials that may inhibit bond, such as oil, curing compound, acid,
dirt and loose debris. Roughen surface and remove all unsound material. The repair
surface must be thoroughly Saturated Surface Dry (SSD) with water.
MIXING: STUCCO MIX can be mixed in a mortar mixer or with a drill mounted mixer.
Use 2.0 to 3.5 quarts (1.9 L to 3.3 L) of water per 50-lb (22.7-kg) bag. Place the
desired quantity of mix water into the mixing container. While the mixer is running, add
STUCCO MIX. Mix for 3 to 5 minutes, or until a uniform, lump-free consistency is achieved.
CAUTION: DO NOT RETEMPER OR OVER-MIX. DO NOT ADD PORTLAND CEMENT, LIME, OR
ANY OTHER ADMIXTURES UNLESS APPROVED BY CTS CEMENT.
PLACEMENT: Organize work so that all personnel and equipment are ready before
placement. Apply and nish using traditional tools and techniques. The working time
of STUCCO MIX is approximately 60 minutes at 70°F (21°C). Complete installation of
mixed materials before stopping work. The working time may be extended by using cold
materials or by adding Rapid Set

.
CURING: Water cure STUCCO MIX by misting the surface with clean water to maintain its
wet sheen until the material is hard and cannot be easily scratched with a nail (minimum
90 minutes). Cold weather or extended setting times will increase the required curing
time. The objective of water curing is to maintain a continuously wet surface until the
product has achieved sufcient strength.
COLD WEATHER: Environmental and material temperatures below 70°F (21°C) may delay
setting time and reduce the rate of strength gain. Lower temperatures will have a more
