WARNING
DO NOT BREATHE DUST AND CUT
ONLY IN WELL VENTILATED AREA
James Hardie products contain sand, a source of respirable crystalline silica which is considered by some international authorities to be a cause of cancer from some occupational sources. Breathing excessive amounts of respirable silica dust can also cause a disabling and potentially fatal lung disease called silicosis, and has been linked with other diseases. Some studies suggest smoking may increase these risks. During installation or handling:
(1) work in outdoor areas with ample ventilation;
(2) minimise dust when cutting by using either ‘score and snap’ knife, fibre cement shears or, where not feasible, use a HardieBlade ® saw blade and dustreducing circular saw attached to a HEPA vacuum;
(3) warn others in the immediate area to avoid breathing dust; (4) wear a properly-fitted, approved dust mask or respirator (e.g. P1 or P2) in accordance with applicable government regulations and manufacturer instructions to further limit respirable silica exposures. During clean-up, use HEPA vacuums or wet cleanup methods - never dry sweep.
For further information, refer to our installation instructions and Material Safety Data Sheets available at www.scyon.com.au. FAILURE TO ADHERE
TO OUR WARNINGS, MATERIAL SAFETY DATA
SHEETS, AND INSTALLATION INSTRUCTIONS MAY
LEAD TO SERIOUS PERSONAL INJURY OR DEATH.
JAMES HARDIE RECOMMENDED SAFE
WORKING PRACTICES
CUTTING OUTDOORS
1. Position cutting station so wind will blow dust away from
the user or others in working area.
2. Use a dust reducing circular saw equipped with HardieBlade ®
saw blade and HEPA vacuum extraction.
SANDING/DRILLING/OTHER MACHINING
When sanding, drilling or machining you should always wear a
P1 or P2 dust mask and warn others in the immediate area.
IMPORTANT NOTES
1. NEVER use a power saw indoors.
2. NEVER use a circular saw blade that does not carry the
HardieBlade ® logo.
3. NEVER dry sweep - Use wet suppression or HEPA vacuum.
4. NEVER use grinders.
5. ALWAYS follow tool manufacturers’ safety recommendations.
P1 or P2 respirators should be used in conjunction with above cutting practices to further reduce dust exposures. Additional exposure information is available at www.jameshardie.com.au
to help you determine the most appropriate cutting method for your job requirements. If concern still exists about exposure levels or you do not comply with the above practices, you should always consult a qualified industrial hygienist or contact
James Hardie for further information.
STORAGE AND HANDLING
To avoid damage, all James Hardie building products should be stored with edges and corners of the sheets protected from damage.
James Hardie building products must be installed in a dry state and protected from weather during transport and storage. The stored product must be laid flat under cover on a smooth level surface clear of the ground to avoid exposure to water, moisture, etc.
Protective gloves must be worn while handling sheets.

SHEET LAYOUT AND SIDE UP
Install sheets across the floor joists with the short sheet edges fully supported on joists in a staggered pattern.
For internal tiled applications, install sheet with label
‘This side DOWN for TILES’ facing down. For internal vinyl/carpet applications, install sheet with label
‘This side UP for VINYL’ facing up.

FRAMING
General
Scyon™ Secura™ Interior flooring may be fixed to either durable timber or corrosion resistant light gauge steel frame joist centres. Floor joist must be a nominal of 45mm wide (except for Narrow Timber I
Joists and LVL solid joist).
Framing must have the appropriate level of durability required to prevent corrosion or deterioration.
Timber Framing
Use of timber framing must be in accordance with
AS1684 - ‘Residential timber-framed construction’, dry kiln, and in accordance with the framing manufacturer’s specifications.
· Narrow Timber I Joists (min. 40mm wide):
Refer to table 3 for specific fastener requirements.
The flange of the joist profile must have an adequate
depth to ensure full fastener embedment.
· LVL solid joist (min. 42mm wide): Refer to table 3
for specific fastener requirements.

INSTALLATION STEPS
NOTES
1. Ensure the product meets aesthetic and product size specifications before installation.
James Hardie will not be responsible for rectifying aesthetic surface variations following installation.
2. The sheet is multi purpose and depending on the finish, the short sheet ends may or may not need a gap. As a result, creep at the short sheet ends will occur and over many sheets additional floor joists may be required.

FIGURE 6 BUTT JOINING OPTIONS
Steel Framing
Framing members must have a 0.75mm to 1.9mm
BMT (base metal thickness) and be in accordance with NASH standard for Residential and Low Rise
Steel Framing Part 1 and manufacturer’s specifications.

FIGURE 9 L-SHAPED ROOM
FIGURE 7 SEALING FASTENERS AND JOINTS
NOTE: Avoid excessive foot traffic on the floor for at least 24-48 hours to allow sealant to set and dry out.
Protect the surface of the sheets from damage until final finish is applied.
FIGURE 10 CONTROL JOINTS - SHEET & TILE JOINT
Additional control joints in the tiles are required in both directions, refer to AS3958.1 and Figure 11 for more information.
CONTROL JOINTS
Tiled dry and wet areas only
Control joints in the floor sheets and thus through the tiles are required in dry and wet areas where floor dimensions exceed 5.4m in the long sheet direction and where existing structural joints are located, see below. For 22mm Scyon TM Secura TM Interior flooring, it may be more practical to have the control joints every 4.8 metres along the length of the sheets to coincide with sheet size.
NOTE: No control joints are required in the flooring sheets when finishing with vinyl and carpet unless there is an existing structural joint or otherwise specified by relevant code and regulation.
accordance with tile manufacturer’s specifications within 3 months of installation.
At the time of writing the following third party companies for warranted waterproofing systems for use with Scyon ™ Secura ™ Interior flooring.
• Ardex Australia Pty Ltd
• Parchem Construction Supplies
• Bostik Australia Pty Ltd
• Crommelin
• ParexDavco Australia.
Vinyl
In Internal wet and dry areas, vinyl can be directly fixed to the sheets. In high risk areas of a wet area eg. shower, a warranted and tested waterproofing system is required.
As the sheets are sealed, it recommended that the vinyl adhesive is allowed to air dry longer to become tacky before laying down the vinyl sheets. Dunlop ®
Vinyl Adhesive, Polymer Vinyl Adhesive 265 from
Polymer Engineering and Fullers ® Perfect Putdown floor adhesive are water based and may be used.
Refer to the above vinyl manufacturers for suitable warranted tested products and installation instructions.
Tiling
In Internal wet and dry areas, tiles can either be directly fixed to the sheets or laid on a sand-cement mortar bed over the sheets. Brittle tile finishes such as slate and marble may need to be laid on a 30mm thick reinforced bed. Refer to tile supplier for warranted specifications and AS 3958.1.
Tiles must be applied with proprietary flexible adhesive applicable for tile thickness and size nominated in code and by tile adhesive company that conforms to ISO
13007.1 for Ceramic Tiles and Adhesives. Use a flexible tile adhesive that is warranted and is suitable for use with Scyon ™ Secura ™ Interior flooring and tiles used.
Tiles are laid from the control joint out and edges of tiles must overlap butt joints a minimum of 50mm.
Refer to the waterproofing and tile manufacture and relevant tiling codes for maximum tile control joint spacing, tile adhesive thickness and application, product suitability and compatibility including grout, tile adhesive, tile and waterproofing warranty and maintenance requirement.
FIGURE 8 SHEET CONTROL JOINT LAYOUT
Also provide control joints where there are changes of direction, such as an L-shaped room, and at doorways where the tiled surface is carried through to the next room as shown.
MAINTENANCE
Cleaning and maintenance of the finished surface, joints, junctions, penetrations etc must be carried out at regular intervals. Maintain waterproofing to meet the objectives of AS 3740 and as per the requirements of the relevant component manufacturer.
FIGURE 11 CONTROL JOINTS - TILE
FINISHES
Ensure all components are fully compatible with one another and warranted for the intended application with Scyon ™ Secura ™ Interior flooring including tiles, vinyl, and waterproofing system and tile and vinyl adhesive.
Preparation
Where minor height variations (3mm or less) occur at sheet butt joints, these may be levelled out by filling with Ardex’s Feather Finish. Sanding of the Scyon ™
Secura ™ Interior flooring is not recommended.
Ensure sheets are fully dry and clean before applying finishes.
