1 VIVA CEMENT BOARD

2 The Earth Friendly Board VIVA WOOD CEMENT BOARD is manufactured from wood, cement and mineralising agent. The combination of these raw materials resulted in a board with unique properties not found in other board materilas. Viva board has benefit of properties of cement, that is, it is extremely durable, resistanto weathering, fungus, moisture, termite and fire. It also has the benefit of wood as it is worable with most wood working equipment. Internals Dry wall, Wall Cladding Sound and Fire Resistance Partition Ceiling, and Wall Lining Toilet and Show Cubicles Flashing Standard Wall Lining Flooring Column Casing Externals Prefabricated House Panels Wall Linings Fascias Roof Decking / Sarking Tunnel Lining Wall Cladding Eave Lining / Soffits CHARACTISTICS Moisture Resistant Due to the mineralisation process of pre-treating the wood particles, these paricles will not rot. Moisture, which normally causes decay in wood, does not effect the wood, since the alkaline content in the cement board retards the development of fugul culture in the long-term. Fire Resistant The fire regulation is becoming mor stringent in the building industry and fire resistand building board are increasingly being used. The presence of cement in VIVA BOARD makes the board resistant to fire. It has been tested and passed under the BS 476 Part 6 and 7, which classified it as a Class 0 material. Viva Board Partition system passed the 1 hour and 2 hours fire rating test according to BS 476 part 22 Workability The presence of wood in the wood cement board enables it to be workable like wood with any normal wood working equipment. It can nailed sawn, drilled or profiled, just like wood.

3 FIXING AND MOUNTING VIVA BOARD can be mounted by using screws, nails, staples or adhesive. The recommended fixing centers for nail and screw are as show. Edge distance can be reduced if pre-drilled holes are used or when using self-drilling screws or compressed air nailing tools. RECOMMENDED FIXING DISTANCES Board Thickness A FROM THE EGDE B ON THE EDGE C IN THE FILED 8-12mm 20mm mm mm 16-24mm 20mm mm mm Above 24mm 20mm mm mm NAILING Panels up to 12mm thickness may be nailed without pre-drilling. For a board thickness above 12mm, a pilot hole of 80% of nail diameter must be pre-drilling through. Length of the nail should be approximately 3 times the thickness of the board STAPLING VIVA BOARD can be fixed to timer frames by using compressed air driven staples. SCREWING When normal wood construction screws are used, a pre-drill of hole size. To 80% of the shank size is necessary. The length of the screws should be approximately three times the board thickness. Self drilling, self embedding head screws can be used with powered screw-drivers without pre-drilling BONDING When glueing VIVA BOARD, use only alkali resistant adhesives. These including polyurethane or epoxy resine base JOINTS The Choice and method of joint details will depend on several factors including - Application - Location (internal or external) - Board thickness - Surface finishing required In order to allow board movements caused by moisture and temperature, a gap of 3mm between boards should be allowed when used in internal application and larger gap of 5-6mm in external application.

4 SURFACE FINISHING VIVA BOARD can be subjected to various types of surface treatment on finishing. However, owing to its alkaline content, it is recommended that the board be primed with an anti-alkali premier, before a finishing coat of paint is applied. PAINTING VIVA BOARD can be coated with a wide rang of paint these include: - Emulsion paint - Gloss paint - Polyurethane (PU) - Polyester - Epoxy FILLING Screw and nail holes, damaged or uneven joints can easily remedied with proprietary filler LAMINATION WALL PAPER VIVA BOARD Can be decorated with vinyl or conventional wallpaper by using appropriate adhesive. When applying overlays, it is recommended that the board balanced by applying a compensation laminated or coat with primer on the undercoated side. To avoid crack at joints, usage of glass fiber reinforced or cellular rubber wallpaper is recommended. TILLING Ceramic tiles and mosaics can be bonded to VIVA BOARD using recommended adhesives. A coat of primer must always be applied on the reverse side. STORAGE AND HANDLING HANDLING Avoid lifting the VIVA board from both ends of short edge. To prevent excessive flexing of the board, the board be lifted by sliding sideways from the stack and lifting on the edge TRANSPORTATION It is recommended to strap the VIVA BOARD together preferably on a wooden pallet when transporting. When strapping, edge protection should be provided to ensure that the board edges are not damage. The boards should be protected against moisture during transportation. This is done by covering thenm with trpaulin or canvas shsst. STORAGE Indivdual sheets should not transported or stored upright. The board should be stored by laying them horizontally on pallets or beams with sufficient support to avoid sagging The board mush be protected from the effect of weather with protective covering sheets In case the board are accidentially exposed to water, they should be allowed to dry individually before restacking

5 FIRE PROTECTION Owing to its high cement content, VIVA BOARD is resistant to fire. VIVA BOARD has been tested and passed BS 476 part 5, 6, and 7 and it is classified as a class 0 material under the British Building Regulation. VIVA BOARD can also be used for fire rated walls.
