Cement Board
Description
PermaBase
®
BRAND Cement Board
is a rigid substrate made of Portland
cement, aggregate and glass mesh
that provides an exceptionally hard,
durable surface that is able to with-
stand prolonged exposure to moisture.
PermaBase offers a competitive
advantage over similar products
on the market with its patented
EdgeTech
®
technology. The tapered,
reinforced edge design allows for
closer nail or screw application to
the edge.
Features/Benefits
䡵 Reinforced edge with EdgeTech
technology allows for closer
fastener application of nails or
screws at the edge without
crumbling or spinout.
䡵 IRC and IBC 2006 Compliant –
Meets ASTM C 1325.
䡵 PermaBase resists the growth
of mold achieving a panel
score of 10, the highest score
possible, per ASTM D 3273.*
䡵 PermaBase resists the growth
of mold achieving a panel score
of 0, the highest score possible,
per ASTM G 21.
䡵 PermaBase is GREENGUARD
Indoor Air Quality Certified
®
.
䡵 Homogeneous core has fewer
voids and provides a very easy
and clean score and snap.
䡵 Can be cut utilizing a standard
utility knife and straightedge.
With PermaBase’s unique core
composition, little or no addi-
tional labor is needed to clean
the edge after a cut.
䡵 PermaBase is impact resistant,
extremely durable and dimen-
sionally stable. It has excellent
overall flexural, compressive and
tensile strength characteristics.
䡵 PermaBase is highly moisture
resistant, and will not rot,
disintegrate or swell when
exposed to water.
䡵 1/2" PermaBase may be used
in 1 hour and 2 hour rated
assemblies and is UL Classified.
䡵 1/4" PermaBase is ideal for
remodeling applications because
it can be applied directly over a
variety of existing countertop
surfaces.
䡵 As a floor underlayment 1/4"
PermaBase eliminates the need
to modify adjacent thresholds
when abutting to carpeting,
wood flooring and other common
flooring materials.
䡵 Lowest water absorption of any
cement board per ASTM C 473.
䡵 Available in various widths,
lengths and thicknesses.
䡵 Can be used in 24" o.c. floor
truss construction, with specific
requirements.
䡵 Suitable for both interior and
exterior applications.

GridMarX

1/4" PermaBase Underlayment
has GridMarX, a pre-printed
fastening pattern that ensures
the proper number of fasteners
while taking the guesswork out
of spacing, layout and trimming.
* When tested by an independent laboratory per ASTM D 3273 ("Standard Test Method
for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental
Chamber"), PermaBase achieved a panel score of 10, the highest score possible, indicating
no mold growth under the laboratory test conditions. The use of PermaBase in actual
installations may not produce the same results as were achieved in controlled laboratory
conditions. No material can be considered "mold proof," nor is it certain that any
material will resist mold indefinitely.
