ON SITE
Upon delivery, House of Bamboo INDECKRITY® decking should be stored in covered area, out of direct sunlight and away from inclement weather. Keep decking at least 40mm off the ground by stacking boards on gluts, and cover material with a tarp to protect the product from ultraviolet (UV) light. House of Bamboo INDECKRITY® decking can be installed immediately and does not need to acclimate to its surroundings.
SUBFLOOR FRAMING
House of Bamboo INDECKRITY® decking is designed to be installed onto bearers and joists, which should be specified per Australian Standard 1684 – Residential Timber-Framed Construction and Australian Standard 1720 – Timber Structures. Both Standards apply primarily to residential structures. The specification of load-bearing timbers in commercial applications should be provided by a structural engineer and are often included in the engineering supplements attached to construction plans for these projects. Subfloor systems that are erected in bushfire-prone areas should additionally comply with Australian Standard 3959 – Construction of Buildings in Bushfire Prone Areas, as the certification of products in BAL-rated systems is not sufficient of itself to meet the design criteria around enclosed or unenclosed subfloor spaces on BAL-rated lots.
VENTILATION
Adequate subfloor ventilation is critical to the long- term performance of all decking materials. If House of Bamboo INDECKRITY® decking is to be installed close to ground level and directly above a concrete slab, the minimum clearance between the slab and underside of the decking boards should be 100mm. In all other applications, the minimum clearance should be 150mm. If House of Bamboo INDECKRITY® decking boards are to be installed close to ground level and directly above loose or compacted soil, a permeable ground structure and drainage should be used to prevent water from pooling and then absorbing into the decking material. An additional 5 to 10mm clearance should be provided between House of Bamboo decking products and adjoining buildings to further enhance ventilation and prevent the warping or distortion of individual boards.
*Note that subfloor structures supporting House of Bamboo INDECKRITY® decking boards should be designed to accommodate a permanent decking mass of at least 25kg/m2.
INSTALLATION
House of Bamboo INDECKRITY® decking boards should be installed per the guidelines provided in Australian Standard 1684 – Residential Timber-Framed Construction. Additional recommendations can be found below:
Spanability: The unique end-matching feature of House of Bamboo INDECKRITY® decking products means that boards can be jointed in conventional fashion on top of joists, or off- joist. When House of Bamboo decking is jointed onor off-joists in residential and light commercial applications, it achieves a maximum span of 462.5mm centre-to-centre.
Spacing: A 3 to 5mm gap is recommended between each row of decking boards and can be achieved through use of our hidden clip system or with spacers in face-fix installation methods. This is standard practice in the installation of timber decks to allow for air circulation between decking timbers, and the expansion or contraction of individual boards over time.
Cutting and Drilling: House of Bamboo INDECKRITY® boards can be cut, ripped, routed and planed like traditional hardwood decking boards. Always use high-quality carbide tipped saw blades and high-speed steel (HSS) drill bits. When required, sand only in the direction of the grain of the decking board with a block or belt sander – do not use an orbital sander.
End Sealing: Use a quality timber sealer as part of the installation process to prevent checking and splitting at the end of cut boards. Clear UV protected water-based finish by Vernites® is applied to regular House of Bamboo INDECKRITY® products at the factory as a priming coat, and should be reapplied to freshly exposed end grain and penetrations as part of the installation process.
INDECKRITY® Raw
Where unprimed INDECKRITY® has been selected by the installer or end user, ensure at least one coat of water-based finish by Vernites® or WOCA® Exterior Wood Oil is applied to all faces and edges before boards are fitted. This will ensure that moisture ingress and egress is consistent on each surface of the decking board, including underneath boards where maintenance is difficult. Failure to coat all surfaces of unprimed INDECKRITY® prior to installation may accelerate cracking, checking, splintering, and general weathering of the decking boards.
FASTENERS
House of Bamboo INDECKRITY® decking boards can be fastened to joists with decking screws through the face of the board, or via hidden fasteners that are installed into the side grooves that run along each length of decking.
If fastening through the face of the decking board:
- Use 10G 10x65mm 304-grade (or higher) stainless steel decking screws.
- Fasten every board with two screws at each joist.
- Pre-drill all screw holes. Screws should be located at least 12mm from board edges, and 50mm from the butt end of each decking board
If fastening decking boards with House of Bamboo hidden clip system:
- Determine the location where fastening clips are to be installed along the length of the decking board.
- Press fastening clips into the groove of the first board.
- Pre-drill and screw fastening clips to the joist.
- Insert the second decking board into installed fastening clips.
- Repeat until all decking boards have been secured to the subfloor system.
Fastening clips should be installed at every junction where a decking board meets a joist.
When installed under this system, 20 x 139 mm House of Bamboo INDECKRITY® decking boards will require approximately 18-20 sets of clips and screws per square metre.
MAINTENANCE
House of Bamboo INDECKRITY® decking boards are manufactured from fused bamboo fibre and will perform like any natural timber product in weather-exposed applications. Once installed, boards can be left to weather and will grey / patina over time.
INDECKRITY® decking boards may also display other general phenomena when exposed to rain and sun as part of the weathering process. These phenomena include checking, splits, splintering, shrinkage and expansion, and can be managed through the application of finishes that protect the substrate from ultraviolet light and moisture ingress and egress.
Where decking boards are to be recoated to preserve their factory finish or to prevent degradation of the bamboo fibre, water-based finish by Vernites® should be applied to clean and dry surfaces according to the manufacturer’s guidelines. Tinted – and not clear or “natural” – finishes should be selected as tinted coatings contain a small amount of pigment that prevents ultraviolet light from damaging the bamboo substrate.
Note that the application of clear coatings may accelerate the natural weathering process and aggravate any checking, splintering and dimensional instability that has already occurred. These finishes should generally be avoided.
CLEANING
A bi-annual cleaning with warm water, mild dish soap and a non-metallic stiff bristle brush will remove most moulds, pollens, tannins, mildew and dirt from the surface of INDECKRITY® decking boards. Exceptionally soiled areas may require application of a specialised deck cleaning product – we recommend House of Bamboo Bamboo Cleaner which has been specifically formulated for use on bamboo products. If using a high-pressure washer to clean House of Bamboo INDECKRITY® boards, select a fan nozzle attachment with a wide spray pattern (wider than 35°) to prevent damage from occurring to the decking boards.
FINISHING
House of Bamboo INDECKRITY® decking boards are shipped with a priming coat of Clear UV protected water-based finish by Vernites®. If the maintenance of this factory finish is desired, one to two coats of water-based finish by Vernites® should be applied to clean and dry decking per the manufacturer’s recommendations.
The first application of decking finish can be performed immediately after installation and is recommended to ensure House of Bamboo factory finish is protected from initial wear and tear. Apply a specialised bamboo cleaner such as House of Bamboo Bamboo Cleaner to boards prior to the application of finishing products to ensure that surfaces are clear of contaminants that might encourage the growth of mould fungi. To maintain the factory colour of your House of Bamboo INDECKRITY® decking boards, apply water-based finish by Vernites®.
