Description
Cement Board Stucco is a water-
managed exterior wall system
designed to provide increased high-
impact and weather resistance and
improved dimensional stability
where exterior insulation value is
not required. For the purposes of
meeting structural racking or fire
code requirements, it is applied
over the following approved
sheathings: Exposure 1 or exterior
plywood (grade C-D or better);
Exposure 1 OSB; glass mat gypsum
substrate meeting ASTM C 1177;
or water resistant core gypsum
(ASTM C 1396).
It combines the strength and dura-
bility of PermaBase Cement Board
with the performance and beauty of
reinforced base coats and textured
finishes. All finishes are available in
a limitless color selection and
offer performance enhancement
options ranging from extra mildew
resistance to added flexibility.
Behind the system, a weather-
resistant barrier complying with
ASTM D-226 protects approved
sheathings and other structural
components and serves as a
component to evacuate incidental
water. Cement Board Stucco allows
you to enclose and finish a project
in as little as two days, speeding
occupancy.
Uses
For high-impact and weather-resis-
tant exterior wall in residential and
low-rise commercial applications.
Advantages
Durability/Strength: Moisture
resistant, durable PermaBase
Cement Board substrates applied
over a primary sheathing provide
extraordinary impact and puncture
resistance to the system.
Weather Resistance: 100%
Acrylic base coats and finishes repel
weather at the system’s surface.
Water-Managed Design: The
water-managed design of the
system provides drainage to the
exterior of incidental water that
might enter around or through
window or door openings and
penetrate behind the cladding in
frame construction.
Water-Managed, High-Impact Resistant
Wall System
Design Options: Cement Board
Stucco provides the popular stucco
look, including the attachment of
special pre-molded shapes and a
wide variety of finish texture and
color options in standard colors
and custom colors.
Contact exterior coatings
manufacturer for color and
installation instructions.
Limitations
䡵 Use is limited to residential and
low-rise commercial applications.
䡵 Thin veneer construction will tend
to reveal planar irregularities in
the frame construction.
䡵 Minor cracking at joints might
become visible in the finished
exterior surface.
䡵 For exterior finishes applied
direct to PermaBase, reinforcing
mesh must be embedded in
basecoat. Consult exterior
manufacturer for additional
installation requirements.
䡵 For conventional Portland
Cement plaster systems,
self-furring metal lath must
be used over PermaBase and
adhered to studs.
