This article shows how to install mgo board for interior partition walls. Please note that there will be three parts and this is only the part one.
1. Site Preparation
1.1 Install MGO board for interior wall only after exterior wall construction is complete. Avoid interior installation before exterior wall completion or window installation.
1.2 Complete major pipeline installations within each floor before MGO board installation.
1.3 Clean the site before installation. Remove dirt, dust, oil, and debris from the substrate area. Scrape away any remaining cement, and level uneven ground as necessary.
1.4 Keep the installation site dry, with no standing water on the floor.
1.5 Ensure joint installation occurs within a temperature range of 5°C to 35°C; avoid installation outside of this range.
2. Material Inspection
2.1 Verify the type, specifications, and quantity of materials before installation.
2.2 Ensure MGO boards are dry, flat, and free from damage or surface bulges.
2.3 Lightweight steel keels should be smooth, rust-free, and undistorted.
2.4 Joint compound must be dry, not damp, and free from clumps.
3. Wall Positioning
Determine the wall position according to design specifications. Mark lines on the floor slab, beam bottom, and ground to indicate the locations of the top and bottom horizontal keels, as well as the positions of doors and windows.
4. Keel Installation
4.1 Secure the top and bottom horizontal keels to the building and ground with expansion screws, shot nails, or other fasteners. Ensure adjacent fasteners are no more than 600mm apart.
4.2 Cut vertical keels according to the distance between the top and bottom horizontal keels (allow a 5mm margin for ease of fitting). Insert the vertical keel into the top and bottom horizontal keels, keeping the opening direction consistent and avoiding upside-down placement to maintain alignment.
4.3 If cutting vertical keels is necessary, face the cut end upward when inserting between the top and bottom keels. The keel spacing should be in accordance with the design requirements. Standard spacing is 600mm, but can also be set at 400mm or 300mm, not exceeding 600mm.
4.4 Use a plumb line to ensure the vertical keel is perpendicular.
4.5 Avoid fixing horizontal and vertical keels immediately. Adjust the keels to align with MGO board tolerances during installation.
4.6 Install one layer of MGO boards on one side of the keel frame.
4.7 Adjust keel positions as needed during MGO board installation. The horizontal and vertical keels can be fixed simultaneously with the MGO board installation.
4.8 Complete internal wall pipe installation and inspection before installing MGO board on the other side.
5. Door and Window Openings
5.1 Break the horizontal keel at the doorway position.
5.2 Position additional vertical keels on both sides of door and window openings, facing the opening away from the frame.
5.3 Use additional horizontal keels to make the frames of door and window openings. Insert vertical keels between horizontal keels to maintain a uniform spacing with other wall keels. For door or window widths over 1800mm, reinforce the structure.
5.4 Follow the same procedure for the lower frame of window openings.
