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...

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...
