Veneer Plaster
Description
Veneer Plaster Systems consist of
a 4' wide gypsum plastering base
with a special, highly absorptive
paper surface that is covered with
thinly troweled, special purpose
plasters. Two basic types of veneer
plaster are available: Uni-Kal and
X-KALibur, which are one-coat
plaster system products; and Kal-Kote,
a two-coat plaster system. The
gypsum plaster base, Kal-Kore, is
erected in the same manner for
both systems. Both veneer plaster
systems can be specified for virtually
all types of partition and ceiling
constructions including wood or
steel framing or furring and masonry.
For both residential and commercial
buildings, either type of veneer
plaster system produces a wall more
nail-pop resistant than drywall
and, when properly installed, more
crack resistant than conventional
lath and plaster.
Features/Benefits
The advantages of veneer plaster
over other commonly used partition
and ceiling systems include:
m
Rapid installation which reduces
overall construction time.
m
Appearance and surface of
conventional plaster at lower
cost than regular plastering.
m
High resistance to cracking,
nail-popping, impact and
abrasion failure.
m
Mill-mixed plaster components
help assure uniform installation
performance and finished job
quality.
One-Coat System
Features/Benefits
(Uni-Kal
®
/X-KALibur
®
)
m
Requires only one plastering
material on the job.
m
Slightly lower in-place cost than
two-coat system.
m
Can be applied directly to
concrete block.
m
X-KALibur is formulated to have
extended set characteristics beyond
traditional Uni-Kal setting times.
Two-Coat System
Features/Benefits
(Kal-Kote
®
)
m
Kal-Kote System may be used
for plaster-embedded electric
radiant heating cable systems.
m
Same application techniques as
for conventional plaster.
m
Greater crack resistance than
one-coat systems.
m
Can be applied directly to
concrete block.
Limitations
m
Not recommended for exterior
use or where subject to weath-
ering, direct water contact or
temperature exceeding 125˚F
(52˚C) for extended periods
of time.
m
Framing spacing is limited and
partition heights are reduced in
comparison with some standard
constructions.
m
Provides less rigidity than similar
standard plaster systems.
m
When Uni-Kal/X-KALibur will be
applied, do not install Kal-Kore
too far in advance of plastering
since Uni-Kal/X-KALibur bond
can be adversely affected if face
of Kal-Kore has become faded
from light. If Kal-Kore has been
faded, apply Kal-Kote Base
Plaster or a plaster bonding
agent to obtain good bond.
m
All are designed for trowel
application. Veneer Plasters
are not suitable for conveyance
or application by conventional
plastering machines.
m
Compared to conventional
plasters, Veneer Plaster Systems
are more subject to beading
(ridging) and cracking at the
joints under rapid drying condi-
tions such as those caused by
low humidity, high temperature
and/or high draft exposure.
m
All provide a base over which
paints or other finishes should
be applied.
m
Do not use a polyethylene
vapor retarder unless structure
is ventilated adequately during
application of veneer plasters.
m
A bonding agent must be
applied to monolithic concrete
prior to application of either
system.
m
Do not sand finished plaster.
