Design flexibility is achieved with veneer plaster systems. 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 appropriate distance, with wide flange pointing toward applicator, secure Z Channel with appropriate fasteners, spaced 24" o.c. driven through short flange. (Note: Power-driven fasteners are not recommended for use with masonry block.) Install 24" wide floor-toceiling insulation board, pressed snugly against web of first Z. Install next Z with the wide flange overlapping the edge of the first insulation board. 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 board to fit remaining space. At exterior corner, attach the Z through its wide flange with narrow flange extending beyond the corner. Begin with a narrow strip of floorto-ceiling insulation, wider than insulation thickness, but not exceeding 3". Continue application of furring and insulation progressively 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 recommended; 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 page 48 and 49. 4. Mix and trowel on Kal-Kote Base and Finish Plaster or Uni-Kal Plaster as described on pages 49-51. PAINTING PLASTER Various job conditions such as suction differences, wet or only partially dry walls, and reactions between paint and lime may cause unsatisfactory paint finishes, particularly on new construction. Alkali-resistant primers specifically formulated for use over new plaster will permit decorating with oil or latex type paints. Quality paint products should be used and manufacturers’ recommendations followed. Finished plaster should be painted or covered to conceal possible discoloration. The paint system should be suitable for use over plaster surfaces that contain lime. It is essential that plaster be sound and completely dry before painting. Under good drying conditions, veneer plaster may be painted 48 hours after application. High build, heavy duty and special purpose coatings such as Epoxy are not recommended over veneer or job gauged lime putty finishes. STORAGE <strong>Gypsum</strong> plaster must be kept dry before use. Storage conditions vary with location and seasonal changes, which may affect storage life. These conditions may affect product characteristics such as setting time, working qualities, component separation, or lumping, etc. Such aging is normally a function of exposure to humid air, temperature, and physical support in warehousing. Adverse storage conditions or prolonged storage may affect the working qualities of the product. Rotate inventory frequently for best results. 52 NATIONAL GYPSUM VENEER PLASTER SYSTEMS
