-Fastening-Safety
Although Chinsun MGO Board is heat and moisture resistant, it should be stored inside during a cool dry place like any sheet artifact. to guard the sides and corners, carry boards on their side. Stack boards flat on dunnage, loose wood, matting or other material and indirectly on the bottom. don't allow Chinsun MGO Board to bow. don't stack the other materials on top of Chinsun MGO Board.
Chinsun MGO Board may be a multipurpose board used inside for walls, floor, ceiling, tile backer board and also outside for sheathing, roof decking and lap siding. counting on how the board is employed and therefore the thickness of the board getting used, will dictate what tools could also be needed.

Acclimation:
Remove the packaging and permit the Chinsun MGO Board panels to acclimate to the space temperature and humidity for 48 hours. Ideally, the boards should acclimate within the room where they're going to be used with the temperature replicating the planned temperature of the space.
Placement:
Placement varies counting on the appliance of the boards. When attaching to cold-formed steel framing (CFS), stagger panels with a 1/16” (1/5mm) gap between boards. When attaching to wood allow 1/8” gap.
Chinsun MGO Board is made with one side smooth finish and one side rough finish. The rough finish are often used as a backer board for tile and other applications.
When laying resilient flooring like Luxury Vinyl Plank, Bamboo Flooring, Eucalyptus Flooring, Vinyl plank or Linoleum over Chinsun MGO Board, fill with a polyurea or modified epoxy seam filler and shave or sand until flush. This helps create a smooth surface and avoids “telegraphing” which is uneven joints to on the wear and tear surface.
-Installation must suits all applicable local, state and federal codes and will also follow industry installation practices.
-Cut Chinsun MGO Board with a carbide tipped scoring knife or an influence saw equipped with a carbide blade. don't use power saws indoors. For best results, use a blade designed specifically for cement board and use a T-square to assist ensure cuts are straight and even.
-For circular cuts and irregular angle cuts use a Roto Zip, Dremel, or equivalent tool, equipped with a cement board bit or carbide tipped bit.
-Start with proper framing and ensure studs are straight and square to permit for adequate fastening surface at adjoining walls and flat stress-free installation of Chinsun MGO Board. Ensure framing is level.
-The fewer cuts that are made the higher and easier installation are going to be. Begin by laying out your floor before fastening to the joists. When planning the layout ensure the cut edges are going to be against the perimeter of the space. Sheets should be spaced evenly and butt tightly.
-Install Chinsun MGO Board on 16” centers. Always support board ends by joists. Slightly countersink each fastener. Leave about 1/8th inch between the perimeter walls and therefore the Chinsun MGO Board to permit for expansion.
-After installing the initial sheet of Chinsun MGO Board flooring, apply a generous amount of Select Construction Adhesive, or equal, to the exposed fringe of the installed sheet of Chinsun MGO Board. Install subsequent sheet of flooring butting joints together tightly. Squeeze alittle amount of well-bonding construction adhesive the surface along the whole seam. Use a spatula to get rid of excess from the butt. After installation of first board, verify the board is level before continuing.
Magnesium Oxide Boards (MgO) are a non-tox board material and certain sorts of fasteners may corrode the board. Because all projects and locations are different, consult an area fastener expert for your location and project. Chinsun recommends employing a 316-stainless steel material for all fasteners. Alternatively, a ceramic coated fastener designed specifically for cement board products can also be acceptable.
-Fastening to wood studs with screws: Use #8 flat head fasteners with high / low threads and a pointy drill point.
-Fastening to metal: Use 18 gauge or heavier, with screw: Use #8 flat head screw with nibs under the top for countersinking into the Chinsun MGO Board, and a self-drilling point for penetrating the sunshine gauge metal. When fastening to light gauge materials lighter than 18 gauge, think about using pneumatic fastening. Other fasteners may strip out lighter gauge studding before countersinking the top of the fastener into the Chinsun MGO Board sheathing. If fastening using pneumatic nails use hardened nails. Pneumatic pressures vary counting on board thickness and stud material used. Always set pressure supported countersinking needs.
-Fastener Installation: Install fasteners no closer than 4” from corners. Perimeter fasteners should be placed 6” apart. Center fasteners should be placed 12” apart. Install fasteners approximately 9/16” from board edge. don't install fasteners at 45º angles. Always begin fastening at one side and proceed to lock across the board to the opposite side to avoid stress.
Chinsun MGO Board doesn't contain any carcinogenic material. We do recommend that installers wear a dust mask and safety glasses during routing, cutting and sanding operations. Never dry sweep Chinsun MGO Board, instead use a wet suppression or HEPA vacuum.
If you're using galvanized steel framing, the chlorides in some MgO sheathing, wont to keep off insects and stop the feeding of mold and mildew, may experience a reaction. There are no reports of such reactions. If using Chinsun MGO Board as a sheathing, we recommend installing a barrier of some type to eliminate direct contact between the board and therefore the framing.
