Recommendations
1.
Surface must be free from dirt,
grease, oil, mold, parting agents,
or any material which will prevent
plaster adhesion.
2. When erecting masonry,
strike joints flush. If masonry has
recessed joints, fill joints flush to
masonry surface with basecoat
plaster, Uni-Kal or X-KALibur and
allow to set.
Exterior Corners
Install cornerbead with adhesive
at least 4 and preferably 16 hours
before plastering. Apply a continuous
bead of adhesive approximately
1/4"x 1/4" along the inside of
both cornerbead flanges. Press the
bead firmly over the corner so that
adhesive is in continuous contact
with masonry surface. Align bead
and allow to stand undisturbed
at least 4 hours.
Kal-Kote Application
Note:
Application shall conform to
ASTM C 843.
Proceed with the full field of the wall
by scratching-in tightly, then double
back immediately with material from
the same batch to a minimum thick-
ness of 1/16" over the block surface,
or as required to level.
Kal-Kote Finishes should be kept
as thin as possible and applied as
described on pages 18 and 19.
Uni-Kal or X-KALibur
Application
Caution:
Since Uni-Kal or X-KALibur
is a one-coat material system,
exercise care in leveling the wall to
compensate for the uneven suction.
Proceed with full field of the wall
by scratching-in tightly, then double
back immediately with same batch
of material to a minimum thickness
of 3/32" over the block surface.
Veneer Systems
Applied to Masonry
with Z Furring
Channel System
Description
This system consists of a Z Furring
Channel, rigid insulation and
the components of the Kal-Kote
and Uni-Kal or X-KALibur Veneer
Plaster Systems. The Z Furring
Channel is manufactured from
galvanized steel (.0179” min. base
steel) and is produced with web
depths of 1", 1-1/2" and 2". The
furring channel which is applied to
a masonry wall holds the insulation
in place and the wide flange serves
as framing for the application of
the Kal-Kore plastering base.
Limitations
1.
Since the interior wall surface
will take the general configuration
of the masonry wall, it may be nec-
essary when applying the system
to unit masonry to use portland
cement plaster to bring the wall to
a plane surface.
2. This system is mainly for new
masonry construction. On well-cured
concrete or masonry, it may be
difficult to properly drive fasteners.
3. Power-driven fasteners shall
be used only for attachment to
monolithic concrete surfaces.
4. Kal-Kore should be applied within
24 hours of foam application.
Application Procedures
1.
Begin application of Z Furring
members by positioning first channel
vertically at a corner, locating it on
the wall adjacent to the wall being
insulated first.
The insulation thickness determines
the distance of Z Furring web from
wall being insulated. At the appro-
priate distance, with wide flange
pointing toward applicator, secure
Z Channel with appropriate fasten-
ers, spaced 24" o.c. driven through
short flange. (Note: Power-driven
fasteners are not recommended for
use with masonry block.)
Install 24" wide floor-to-ceiling
insulation panel, pressed snugly
against web of first Z. Install next
Z with the wide flange overlapping
the edge of the first insulation
panel. Fasten Z to wall through
narrow flange. Continue in this
manner with Z Furring member
24" o.c. to end of wall. Locate last
Z so that web is located a distance
equal to insulation thickness from
adjoining wall. Cut last insulation
panel to fit remaining space.
At exterior corner, attach the Z
through its wide flange with nar-
row flange extending beyond the
corner. Begin with a narrow strip
of floor-to-ceiling insulation, wider
than insulation thickness, but not
exceeding 3". Continue application
of furring and insulation progres-
sively as described above.
At windows, doors and trim areas,
use wood nailers, nominal 2" wide
x insulation thickness plus 1/32".
Use the nailers also at wall-floor
angles to support trim and provide
backing for base.
2. Apply Kal-Kore to the flanges of
Z Channel with 1" Type S screws
spaced 12" o.c. Normally, vertical
application of Kal-Kore is recom-
mended; however, for installations
8' or less in height, horizontal
application may be preferred since
the number of joints would be
reduced.
3. Apply Kal-Mesh and Kal-Korner
Bead according to procedures
described on pages 16 and 17.
4. Mix and trowel on Kal-Kote
Base and Finish Plaster or Uni-Kal
Plaster as described on pages 18
and 19.
