Three acceptable methods of
treating Kal-Kore joints are:
Drywall Paper Tape
Treatment Method
1.
Trowel Kal-Kote Base Plaster,
Uni-Kal or X-KALibur over joint line
filling the channel formed by the
tapered edges of the Kal-Kore board
in an even fashion.
2. Center drywall paper tape over
the joint line and embed the tape
into the soft plaster using a trowel
and level the joint. Tape the full
length of the joint.
3. Allow the treated joints to set
prior to general plaster application.
Sta-Smooth Paper Tape
Treatment Method
1.
Mix ProForm
®
brand Quick Set
TM
Setting Compound per instructions
on package. Do not contaminate
the compound with other materi-
als, dirty water or previous mixes.
Do not retemper.
2. Apply the ProForm
®
brand Quick
Set
TM
Setting Compound to the joint
by hand or machine tool. The dry-
wall paper tape must be centered
over the joint line and embedded
into the soft compound. Do not
over-trowel to a slick surface.
Leave the surface rough to provide
mechanical keying of the plaster.
3. Allow the treated joints to set
and dry prior to general plastering.
control joints are created using E-Z
Strip Control Joints.
4. Fasten Kal-Kore to framing
members with face out, using the
proper type and spacing of fasten-
ers shown under types of fasteners.
5. Draw Kal-Kore tight to framing.
Drive fasteners straight and dimple
the surface without breaking the
paper face.
Veneer Cornerbead
Application
Install Veneer Cornerbead using appro-
priate fasteners spaced 12" apart.
E-Z Strip Control Joint
Application
Install E-Z Strip Control Joint at 30'
max. spacing on walls and 50' max.
spacing in either direction on ceilings.
Apply the control joint with staples
spaced 6" along each side of the
flanges.
Treatment of Kal-Kore Joints
Pre-treat all joints and fasteners in
Kal-Kote and Uni-Kal Plaster Systems
with Kal-Kote Base Plaster, Uni-Kal,
X-KALibur or ProForm
®
brand
Quick Set
TM
Setting Compound.
Low humidity, high temperatures
and rapidly circulating air can
cause cracking of plaster and joint
beading when Kal-Kore is applied
to metal framing. To minimize this
during these conditions, joints may
be pre-treated using paper tape.
Veneer Plaster
for Metal
and Wood Framing
1. Wood Studs or Joists. Wood
members shall meet the minimum
requirements of local building codes.
Framing shall not exceed spacing
shown on page 14. Most partition
fire ratings require that Kal-Kore be
applied vertically. When such ratings
are not required, horizontal applica-
tion may be used to minimize joints.
For ceilings, application at right
angles to framing is preferred.
2. Metal Studs. Align floor and
ceiling tracks to assure plumb parti-
tion. Secure track with appropriate
fasteners at a maximum of 24" o.c.
Position studs in track on specified
centers by rotating into place for a
friction fit. Secure studs located adja-
cent to door and window frames,
partition intersections and corners
by self-drilling sheet metal screws
through both flanges of studs and
tracks or by use of screw stud clinch-
ing tool. Apply Kal-Kore vertically for
most fire ratings. When ratings are
not required, horizontal application
may be used to minimize joints.
3. Masonry Wall Furring with
Screw Furring Channel.
Attach
furring channel vertically spaced
not to exceed spacing shown on
page 14. Fasten each channel with
concrete stub nails or appropriate
fasteners through channel flanges
into the masonry or concrete.
Fasteners shall be spaced on
alternate flanges not over 24" o.c.
Apply Kal-Kore vertically or
horizontally in maximum lengths
to minimize end joints.
4. Furred Ceilings with Bar Joists.
Attach regular furring channel 16" o.c.
to bar joists spaced up to 4' o.c.
Resilient Furring Channel (wire-tied
only) shall span a maximum of 24".
Wire tie Furring Channel to joists or
use 1-1/2" Drywall Furring Channel
Clip for 1-1/2" carrying channel. Apply
Kal-Kore with paper bound edges at
right angles to the furring channel.
Kal-Kore Application
Note: Application shall conform to
ASTM C 844.
1. Cut and position Kal-Kore accu-
rately. Bring all joint edges together
but do not force into place. Position
all end joints over framing members.
To avoid ridging, minimize gaps
between adjacent panels.
2. Minimize the number of end
joints by using maximum practical
lengths with proper positioning.
3. Stagger joints so that they occur
on different framing members and
will not be directly opposite one
another on partitions. Avoid joining
Kal-Kore at corners of doors, window
frames, and other openings, unless
