For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required
9、 in respective project, whether or not brackets are present.Comments, suggestions and recommended changes for this guide specification are welcome and should be submitted as a Criteria Change Request (CCR).*NOTE: Veneer plaster consists of a 2 to 3 mm 1/16 to 1/8 inch thick plaster coating applied i
10、n one or more coats to a special gypsum lath base over metal or wood framing. Veneer plaster provides a hard, dense finish for areas such as corridors and conference rooms of major facilities where walls are subjected to frequent impact and where appearance is important. It should not be used in sho

The one-coat is slightly lower in cost, requires less installation time,
21、 and requires only one plastering material on the job. The two-coat system has greater crack resistance and is more resistant to damage. The one-coat system should be used where appearance is the sole consideration. The two-coat system should be used where physical abuse is a consideration.*Except w
22、here otherwise indicated or specified, conform to ASTM C 754, ASTM C 843, and ASTM C 844. Apply the gypsum veneer plaster as a one coat two coat system over a special gypsum base. The veneer plaster, gypsum base, and joint reinforcement shall be products of the same manufacturer. The extent and loca
23、tion of veneer plaster shall be as shown on the drawings. Metal framing is specified herein. Wood framing specified in Section 06 10 00 ROUGH CARPENTRY may be used as an option to SECTION 09 26 00 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,

Submittals should be kept to the minimum required for adequate quality control.A “G” fol
25、lowing a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is su
26、fficiently important or complex in context of the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Residen
27、t Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy, Air Force, a
28、nd NASA projects.Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.*Government approval is required for submittals with a “G“ designation; submittals not having a “G“ designation are for Contractor Quality Control approval.fo
29、r information only. When used, a designation following the “G“ designation identifies the office that will review the submittal for the Government.

31、on or networking permitted without license from IHS-,-,-Certification shall be performed annually and shall be current.1.5 DELIVERY AND STORAGEDeliver and store plaster materials in the manufacturers original unopened containers. Store materials off the ground within a completely enclosed structure
32、or enclosed within a weathertight covering. Store gypsum base and gypsum backing board flat to prevent warping and protect from excessive exposure to sunlight.1.6 SCHEDULINGCommence application only after the area scheduled for veneer plaster work is completely weathertight. The heating, ventilating
33、, and air-conditioning systems should be complete and in operation prior to application of the plaster. If the mechanical system cannot be activated before veneer plastering is begun, the plastering may proceed in accordance with an approved plan to maintain the environmental conditions specified be
34、low. Apply plaster prior to the installation of finish flooring and acoustic ceiling.1.7 ENVIRONMENTAL REQUIREMENTS*NOTE: Veneer plaster is a very thin coating that will be adversely affected by extreme or non-uniform drying conditions and by rapid changes in temperature. It should not be used in sp
35、aces where adequate environmental control cannot be obtained.*Do not expose the gypsum base to excessive sunlight prior to plaster application, as bond failure of the plaster may result. Maintain a continuous uniform temperature of not less than 10 degrees C 50 degrees F and not more than 27 degrees
36、 C 80 degrees F for at least one week prior to the application of veneer plaster, while the plastering is being done, and for at least one week after the plaster is set. Shield air supply and distribution devices to prevent any uneven flow of air across the plastered surfaces. Provide ventilation to
37、 exhaust moist air to the outside during plaster application and set, and until plaster is dry. In glazed areas, keep windows open top and bottom or side to side 75 to 100 mm 3 to 4 inches. Openings can be reduced in cold weather. For enclosed areas lacking natural ventilation, provide temporary mec
38、hanical means for ventilation. In unglazed areas subjected to hot, dry winds or temperature differentials from day to night of 10 degrees C 20 degrees F or more, screen openings with cheesecloth or similar materials. Avoid rapid drying. During periods of low indoor humidity, provide minimum air circ
39、ulation following plastering and until plaster is dry.1.8 FIRE RESISTIVE CONSTRUCTION*NOTE: For fire-resistive assemblies, drawing details must follow the tested and approved designs. The addition of veneer plaster to an approved gypsum wallboard design will improve the fire-resistive properties of
40、the partitions. Tested and approved designs are published by gypsum wallboard manufacturers, Underwriters Laboratory, SECTION 09 26 00 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-and Factory Mutual, and are included in the Gypsum Associatio
