It is grey in colour and available in a 600ml sausage. Uses  Non-trafficable control joints in concrete, masonry, aerated concrete and brick fire rated construction.  Acoustic sealing between most common building materials such as concrete, masonry, aerated concrete, plasterboard, fibre cement, metals, timber and plastic as part of a suitable design.  Penetrations and perimeter sealing in plasterboard and aerated concrete  Sealing in conjunction with fire collars, pillows and dampers. Features/Advantages  Meets BCA requirements for fire and acoustic sealing  Fire rated for up to 4 hours  Will not degrade acoustic walls up to 67Rw  Excellent adhesion to most building materials  Paintable  Water clean up  Low VOC  Halogen free  Isocyanate free Instructions for Use/Application Instructions The following should only be used as a guide and the installer should apply all Australian Standards, BCA/NZBC requirements, and best practices when using Proseries Fireblock.  Substrates must be clean, dry and free from oil, grease, release agents, dust and loose material.  For fire rating, joint width should be between 10mm and 40mm. Minimum joint depth should be 10mm or half the width for joints wider than 20mm. Install open cell polyurethane backing rod in joint to control sealant depth.  Extrude sealant smoothly into joint, while ensuring that all substrates are well wetted out with sealant.  The sealant cures by water evaporation; therefore cure rate is dependent on humidity, ambient temperature and joint size. Typically, the sealant will form a thick skin within 24 hours and full cure can be expected after 7 days.  In humid or cool conditions the sealant cure will be longer.  Allow the sealant to form a thick skin before painting with a flexible paint. To avoid paint cracking, the sealant should be allowed to fully cure before painting with flat and/or ceiling paint. Standards Tested  AS1530.5-2005 Fire test in vertical concrete and plasterboard – control joints, penetrations and perimeter seals  ISO 717-1 Acoustic testing in plasterboard lined wall  ASTM E1966-07 Vertical control joints  ASTM E814-09 Vertical plasterboard wall with penetrations  ISO9046 Joint movement capability www.selleystrade.com.au Page 1 of 3 December 2009
