FastSet

Stucco Mix
• FastSet
™
Stucco Mix may be applied with a trowel or
sprayer according to typical stucco techniques.
• WEAR IMPERVIOUS GLOVES, such as nitrile when
handling product.
• Variation in water addition will affect color
uniformity.
• Do not add additional water during application.
• Avoid overlapping fresh stucco over previously dried
areas as this will result in a lack of color uniformity.
• FastSet
™
Stucco Mix can be painted approximately
3 hours after application with a water-based latex
paint. Only water based coatings are recommended.
APPLYING THE SCRATCH COAT
• Trowel the scratch coat onto the lath or mesh,
working from bottom to top. The scratch coat
should be minimally 3/8” (10 mm) thick. Force it
through the wire mesh so that it fills the gap 1/4” (6
mm) between the mesh and wall completely.
• Smooth the scratch coat with a trowel
• After the scratch coat has set enough to be firm but
not hard, use a rake to scratch horizontal grooves
approximately 1/8” (3 mm) deep across the face of
the base coat mortar.
• If the brown coat is not being applied within
several hours of the scratch coat having hardened
sufficiently, proceed with moist curing the scratch
coat per the instructions below.
APPLYING THE BROWN COAT
• Dampen the surface of the scratch coat with a fine
spray of water (do not soak).
• Use a trowel to apply the brown coat to a minimal
thickness of 3/8” (10 mm). Do the entire wall section
in one work session, otherwise a difference in color
may be noted through the finish coat.
• Screed the brown coat evenly by running the edge
of a straight edge or rod over the brown coat and
smoothing out the high and low spots.
• After the brown coat has lost its sheen, float it
smooth.
MOIST CURING
Keep moist to minimize cracking. Typical moist
curing requires a fine mist of water three hours after
application and a secondary misting after three
additional hours. Mist applications should be increased
for hot, dry, sunny or windy conditions. Care must be
exercised to avoid erosion damage to plaster surfaces
when dampening. For typical scratch then brown-coat
applications which do not have significant interruption
between the coats, moist curing is not required
between the coats. If the application sequence is
interrupted by more than a few hours, the existing
coat should be dampened prior to application of the
successive brown or finish stucco coat. Stucco should
not be dampened before painting.
Precautions
• Do not apply when temperatures are expected to
fall below 40°F (4°C) within a 24 hour period.
• Do not apply when rain is expected within 4 hours
after application.
• Mix only as much material as can be applied in 30
minutes.
• The final color of FastSet
™
Stucco Mix, like other
cementitious materials, may vary due to water
addition, application techniques, and environmental
conditions.
• Paint only using a water-based latex paint, or coat
with a water-based coating.
