Types of Cutting Tools and Blades Cut Cedar and Smooth Plank face down, below are recommended cutting practices. When fiber cement is cut or drilled, it will create dust. This dust may contain crystalline silica, which can pose a health risk. Ensure adequate ventilation by working outdoors or by using mechanical ventilation to reduce potential exposure below applicable exposure limits. The use of recommended cutting tools and blades can greatly reduce the amount of dust generated when cutting fiber cement. Use a polycrystalline diamond-tipped fiber cement blade for circular, miter, and table saws ranging from 7-1/4" to 12" (cut up to 5 panels at the time). For irregular or radius cuts, use scroll cutting shears or jigsaw equipped with a medium polycrystalline diamond-tipped blade or course grit carbide-tipped blade. Use a masonry hole saw for making penetrations for plumbing pipes or other similar cuts. Circular saws with conventional carbide-tipped blades can also be used. Shear-type tools will also cut fiber cement. These tools cut with relatively little effort, less noise, and virtually no dust. The cut is not as smooth as the cut of a polycrystalline diamond-tipped blade, but is acceptable Always re-seal field-cut edges of butt end/joint with 100% acrylic latex paint, primer or Hydro Block prior to installation.
Types of Fasteners Non-corrosive, double hot-dipped, galvanized or stainless steel nails or screws specially designed for fiber cement are recommended. Screw type is determined by application and/or wall design see below fig 3: Fig-3 1

Fastening to Wood
The maximum stud spacing allowed is 24". Refer to local building codes for structural requirements. Nails must penetrate a minimum of 1-1/4" into the structural framing. If you use screws, a minimum of 3/4" must penetrate the structural framing. Some screws may require more than 3/4” penetration to resist lateral loads refer to the screw manufacturer for requirements. You can hand nail fiber cement but fiber cement is harder than wood, so be sure the nails are well set before driving them. It may be necessary to predrill the holes at the corners to prevent the edges from breaking.
Fastening to Metal Framing
Cedar / Smooth Plank can be installed over metal framing. The maximum stud spacing allowed is 24". Self-tapping, corrosive-resistant, ribbed bugle-head screws specifically designed for Fiber Cement are recommended. Fiber cement must be attached to the metal framing members. Screws must penetrate into the metal framing a minimum of 1/4" or three threads. Fig-4: Fasterners must fit snug against Multi-Panels Cedar / Smooth Plank

Drive fasteners perpendicular to Siding and Framing.
• Fastener heads of screws/nails should fit snug against siding, no air space. (Fig 4 no. 2 ) • If nail is countersunk, fill nail hole and add a new nail. (Fig 4 no 1 and 3) • Do not use staples and no air space accepted for fasteners (fig 4 no. 4 and 5) • Do not drive nails/screws at an angle • Do not use aluminum fasteners, staples, or clipped head nails
Types of Cutting Tools and Blades Fig-5: Installation instruction Blind Nailing
Drive fasteners ONLY where Planks overlap and into the Studs
Use Joint flashing behind stagger butt joints
Fasteners must not be closer than ½” from end of the Plank, predrill to avoid cracks.

Processing and Storing Safety
As for all other building materials, safety precautions must be taken into account and local laws and regulations must be observed. Cutting and drilling are subject to dust development, and proper precautions must be taken by using appropriate dust extraction equipment. Dust from fibre-cement panels is characterized as mineral dust and a prolonged exposure to this may cause lung disease. Fast running electrical equipment hand held circular saws leave a fine and sharp edge on the panels and provide fine dust. Due to the speed of the blade the dust is dispersed over a larger area. Therefore, it is necessary to establish sufficient exhaustion and it is recommended the operator carry personal safety equipment.
Application conditions
Panel temperature and ambient temperature should be + 44°F (+7 °C) - 86°F (+30 °C) and relative humidity <85 % (optimally 60 %). Process temperature must be min +44°F (+7 °C).
Painting & Caulking
Use high quality 100% acrylic latex paint or stain. X Use high quality, exterior grade, color matched or paintable caulk or sealant that meets ASTM standard C-920 and is compatible with both Multi-Panels Fiber Cement Siding and the trim materials. Be sure to caulk wherever the siding meets the trim and around non-self-flashing penetrations and all windows and doors. Never apply oil-based paint or stains. Do not caulk the bottom of the horizontal joint that is above “Z” flashing. Always re-seal field-cut edges of butt end/joint with 100% acrylic latex paint, primer or Hydro Block prior to installation. 6
Storing- Lifted off
Multi-Panels products are delivered with plastic protection cover on the pallet. If undamaged, the plastic cover protects against weather conditions during transportation. The plastic cover is for dust protection only and should be removed upon arrival at the building site. Hereafter the pallets should be kept under a roof, leaving the possibility of ventilation around the panels. Multi-Panels must be stored on a flat and dry level surface on pallets or sleepers with max 400 mm distance. Note! max 5 pallets in a stack at the warehouse and on the building side max 2 pallets in a stack. The panels must be lifted off the pallet and not drawn over the next board, as this will cause scratches and damages on the surface.Lift pallet crosswise and set forks apart to minimize bending of pallet. Fork length must support pallet entirely; if required, use fork extensions.
General Information Annual Inspection
Normally, a Multi-Panels Siding does not require maintenance to maintain its strength, properties and function, but an annual inspection of the surface, ventilation gaps, joints and fixings is recommended. Environmental impacts may, however, influence the visual appearance of the façade, detection and repair of possible damages secure a prolonged lifetime for the facade.
High Pressure Cleaning
Warning High Pressure Cleaning is a rough treatment of a fibre cement Siding. Use of a high pressure cleaner may damage the surface. Therefore, high pressure cleaning is not recommended.
Cleaning of dirt
Never clean Cedar/Smooth Plank in bright sunlight, the siding panels can be cleaned with cold or hot water with the addition of a mild household detergent not containing solvents, before cleaning full scale it is recommended to test the selected cleaning method on a smaller area to make sure it answers its purpose. Rinse with plenty of clean water until the facade is perfectly clean.
Moss and Algae removal
Never clean in bright sunlight, moss and algae growth can be removed with common detergents available on the market, examples are: “Klorin” or “Rodalon” 2.5% active that has a long-term effect preventing of new growth. After wetting the Multi-panels with clean water, the detergents is applied according to the supplier's instructions. Do notleave the detergents to dry completely and rinse with lots of clean water to remove the moss and algae.
Impact by Pollution and Nature
The weather and nearby vegetation may affect the appearance of the panels. Could be pollution, dust and leaves from trees, bushes and flowers do all together have an impact on the panels.
