Product catalog summary
Overview of Veneer Plaster Systems
Veneer Plaster Systems consist of a gypsum plastering base with an absorptive paper surface, covered with thinly troweled plasters. Available in one-coat systems (Uni-Kal and X-KALibur) and a two-coat system (Kal-Kote), these systems are suitable for partitions and ceilings, offering better resistance to nail-pops and cracks compared to drywall.
Features and Benefits
These systems allow for rapid installation, are cost-effective, and provide high resistance to cracking and impact. The one-coat system is economical, while the two-coat system offers enhanced crack resistance and compatibility with electric radiant heating systems.
Limitations
Veneer plaster systems are not recommended for exterior use or environments exposed to weathering, water, or high temperatures. They have limitations in framing spacing and partition heights and are prone to beading and cracking under rapid drying conditions.
Product Shelf Life
All products, including X-KALibur, Kal-Kore Basecoat, Uni-Kal, Kal-Kote Smooth, and Kal-Kote Texture, have a shelf life of 12 months.
System Components
Kal-Kore is a gypsum wallboard plastering base with a blue absorptive face paper. Hi-Abuse and Hi-Impact Kal-Kore Fire-Shield Type X panels offer fire and impact resistance. Specifications include various sizes and thicknesses with tapered edges.
Specifications
Details include sizes, thickness, and edge types for Kal-Kore panels, framing or furring spacing guidelines, and fastener types and spacing for attaching Kal-Kore.
Application Methods
Instructions are provided for treating Kal-Kore joints using drywall paper tape or Sta-Smooth Paper Tape, and guidelines for applying veneer plaster over wood and metal framing, masonry walls, and furred ceilings.
Accessories
Includes Kal-Korner Bead, Expanded Veneer Cornerbead, Arch Cornerbead, Veneer J and L Trim Casing Beads, E-Z Strip Control Joint, Kal-Mesh Tape, and various clips and joints for installation.
Specifications and Recommendations
Emphasizes proper joint staggering, avoiding direct exposure to heat and drafts, and maintaining suitable temperature conditions during installation.
Kal-Kote Application Procedures
Involves tightly scratching material into treated joints and corner-beads, followed by a double back application. Advises against over-troweling and highlights roughening the basecoat plaster surface for mechanical keying.
Mixing Instructions
Mixing should be done with a high-speed mechanical mixer using clean, fresh water. Specific water ratios are provided, and thorough equipment cleanup is advised to prevent set acceleration.
Job Setting Adjustments
Commercial retarders or accelerators may be used cautiously to adjust setting time under extreme conditions.
Kal-Mesh Treatment Method
Kal-Mesh should be centered and secured over joints and interior angles with staples, with specific instructions for staple positioning and pre-treating joints.
Plastering and Painting
Plastering should conform to ASTM C 843 standards. Good job conditions should be maintained, and alkali-resistant primers used for painting after ensuring the plaster is completely dry.
Veneer Plasters Direct to Bond-Coated Monolithic Concrete
The Kal-Kote System can be applied directly to monolithic concrete treated with a bonding agent, with limitations such as concrete aging and waterproofing requirements.
Veneer Plasters Direct to Unit Masonry
Recommendations for applying the Kal-Kote System directly to masonry surfaces emphasize clean surfaces and proper joint treatment.
Veneer Systems Applied to Masonry with Z Furring Channel System
Involves the use of Z Furring Channels, rigid insulation, and Kal-Kote or Uni-Kal Plaster Systems, with detailed application procedures and limitations.

Kal-Kore Plaster Base-1

Veneer Plaster 09 26 13/NGC Two-Coat System Features/Benefits (Kal-Kote® BRAND) Ⅵ Kal-Kote System may be used for plaster-embedded electric radiant heating cable systems. Ⅵ Same application techniques as for conventional plaster. Ⅵ Greater crack resistance than one-coat systems. Ⅵ Can be applied directly to concrete block. Limitations Ⅵ Not recommended for exterior use or where subject to weathering, direct water contact or temperature exceeding 125˚F (52˚C) for extended periods of time. Ⅵ Framing spacing is limited and Description Features/Benefits 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 KalKote, 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. The advantages of veneer plaster over other commonly used partition and ceiling systems include: Ⅵ Rapid installation which reduces overall construction time. Ⅵ Appearance and surface of conventional plaster at lower cost than regular plastering. Ⅵ High resistance to cracking, nail-popping, impact and abrasion failure. Ⅵ Mill-mixed plaster components help assure uniform installation performance and finished job quality. partition heights are reduced in comparison with some standard constructions. Ⅵ Provides less rigidity than simi- lar standard plaster systems. Ⅵ 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. Ⅵ All are designed for trowel application. Veneer Plasters are not suitable for conveyance or application by conventional plastering machines. Ⅵ Compared to conventional plasters, Veneer Plaster Systems are more subject to beading (ridging) and cracking at the joints under rapid drying conditions such as those caused by low humidity, high temperature and/or high draft exposure. Ⅵ All provide a base over which paints or other finishes should be applied. Ⅵ Do not use a polyethylene vapor retarder unless structure is ventilated adequately during application of veneer plasters. Ⅵ A bonding agent must be applied to monolithic concrete prior to application of either system. Ⅵ Do not sand finished plaster.

Recommendations 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 application 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 partition. Secure track with appropriate fasteners at a maximum of 24" o.c. Position studs in track...

Kal-Mesh Treatment Method Do not use self-adhering mesh. 1. Center and secure Kal-Mesh over all joints and interior angles with 1/4" or 5/16" staples. 2. Position staples a maximum of 24" apart as follows: A. Joints: at alternate edges for the run from end to end and directly opposite one another at either end. B. Angles: along ceiling edge only for wall-to-ceiling angles. Along one edge for wall-to-wall angles. 3. After the first staples are placed at the end of a joint or angle, pull unstapled Kal-Mesh as stapling proceeds to assure that it will lie flat against the Kal-Kore. 4. Pre-treat all...
