Framing & Fixing Specification

 
Framing Requirement
 
 
The table stipulates the minimum framing requirement. It is a good building practice to provide equal support spacing not exceeding the recommended centre distance to suit the sheet size. In all cases sheet edges must be supported.

Timber framing should be thoroughly selected and dried to minimize shrinkage when boards are installed. Steel frame thickness should be 0.50mm base metal thickness (BMT) to 1.15mm BMT.

** Please refer to HCI technical department for further detail.
 
Fixing Details
 
 

Note: 
1. Screw fixing is only suitable for 6mm thick board and above. 
2. Screw head must be embedded 0.5mm below board surface. 
3. Nails and screw must be suitable coated for the intended applications 
All nails shall comply with 'AS 2334: 1980-STEEL NAILS - METRIC SERIES' or equivalent standard. 
All screws shall comply with 'AS 3566: 1988; SCREWS - SELF DRILLING - FOR THE BUILDING AND CONSTRUCTION INDUSTRIES' or equivalent standard.
 
 
Flush Joint Wall Application
 
PRIMAlinerTM sheets must be fixed horizontally (Figure L1) or vertically (Figure L2), ensuring the vertical sheet joint on one side of the stud does not coincide with the vertical sheet joint on the other side to further enhance the stability of the wall.
 
 
 
Note: PRIMAlinerTM sheets must be fixed with a clearance gap of 6mm from ground floor surface.
Figure L1 & L2 are typical configuration for standard wall height up to 3m.
 
 
 

Framing & Fixing Specification

 
Cutting
 
PRIMAlinerTM sheets can be cut using common power assisted tools such as circular saw equipped with a diamond-tipped cutting blade. This operation must be carried out in a well-ventilated area only. Do not wet the sheet or the saw blade during cutting process. Power tools fitted with dust-extracting attachments are recommended. A dust mask and safety goggle must always be worn when cutting, drilling or grinding the sheet.
 
 
Penetrations
 
Round holes can be formed by drilling a series of smaller holes around the perimeter of the proposed opening, and subsequently tapping the waste piece out carefully. Trim the rough edges with rasp if required. Use suitable high-speed heavy duty drill bit. Rectangular or square openings can be achieved by using power assisted circular saw.
 
 
Handling & Storage
 
Always lift sheets vertically, on-edge and lengthwise. Store PRIMAlinerTM neatly on a flat surface supported evenly on bearers spaced at 600mm centres maximum, clear from ground to avoid damage and moisture ingress. Store under cover and ensure PRIMAlinerTM is dry prior to fixing. Never install damp or wet sheets as they are prone to shrinkage and subsequently may lead to joint failure. Damp or wet sheets must be allowed to dry to equilibrium moisture content before fixing.
 
 
Finishing
 
PRIMAlinerTM can be decorated with 2 coats of 100% quality water-based acrylic paint. For general-purpose applications, there is no requirement for primers or sealers. Please refer to paint manufacturer for advice. Alternatively, the sheet surface can be decorated with wall covering materials, such as wall paper. In all cases, coating manufacturer's recommendations must be strictly adhered to. For wet area application, tile finishing may be preferable
