MgO has excellent adhesion values that are perfect for Portland stucco, acrylic stucco, wallpaper, stone, tile, brick, and much more. MgO’s adhesion values also allow it to be endorsed by most major suppliers of finishes including Imasco Minerals, Master Wall, Acrylabs, Mapei, Surecrete, Carpenter Stone, Total Wall, Stucco Flex, and Encap are part of a growing list. Since MagO Board is glass smooth on one side, a level five beautiful and durable finish can be achieved with much less work than typical gypsum board and it can be painted the same day as they are installed. For paint, it is recommended to use a specified primer .
Wherver gypsum and fiber-cement products are used, MgO is a superior alternative. Applications include: interior walls, ceilings, backer board, and underlayment; exterior wall cladding, soffit, siding, and trim. MgO is also widely used in MgO Insulated Panels (MIP) and such Original Equipment Manufacture (OEM) applications as MagO Cladding System, an integral rain-screen commercial grade siding.
MgO board has different characteristics than gypsum. It can be scored and snapped but better results come from cutting with carbide saws and shaping with routers. Attachment can be done using a nail gun, which results in much faster construction time or screws that are able to self countersink work. MgO board generally has superior strength than gypsum for impact, fastener holding, and shear applications. A single screw in a 12 mm board can hold 200 lbs in shear and half that amount in tension. Due to its hardness, Corner and J beads are not required. Joints do not have to be on a stud and it is possible to go from board installation to painting the same day. Moreover, because of its stiffness, thinner boards can be used.
