Magnesium Oxide Board Installation Instructions

Essential Tools

You’ll need a few key tools to measure, cut, and fasten the boards securely. Here’s what to have on hand:

Tip: Use a dust-reducing circular saw and wet suppression methods to minimize airborne particles during cutting.

Required Materials

Now that you’ve got the tools, let’s talk about the materials you’ll need to complete the installation.

Note: Always store your materials in a dry, flat area to prevent warping or damage before installation.

Cleaning and Leveling

1. Remove dust, debris, and grease: Start by thoroughly cleaning the surface. Sweep away dust and debris, and wipe off any grease or oil. If the surface is damp, consider laying down a moisture barrier to protect the boards from future water exposure.
2. Fill cracks or holes: Inspect the surface for any cracks or holes. Use a leveling compound to fill them in, then sand the area until it’s smooth. Uneven surfaces can cause improper board placement, so take your time with this step.
3. Ensure a smooth finish: Magnesium oxide boards are brittle and can crack if placed on uneven surfaces. Skim coating and sanding may be necessary to achieve a perfectly level base.

Tip: A clean and level surface is critical for a successful installation. Skipping this step can lead to poor adhesion and long-term damage.

Step-by-Step Magnesium Oxide Board Installation Instructions

Step 1: Cutting the Boards

Measure and mark the boards for cutting.

Start by measuring the dimensions of the area where the MgO board will be installed. Use a tape measure for accuracy and a square ruler to ensure straight lines. Once you’ve got the measurements, mark the cutting lines on the board with a pencil or chalk. Double-check your markings to avoid mistakes.

Use a utility knife or saw to cut cleanly to size.

For thinner boards, the score-and-snap method works best. Use a utility knife to score along the marked line, then snap the board cleanly. For thicker boards, opt for a circular saw with a carbide blade. This tool ensures smooth, precise cuts. If you’re looking for even more control, a plunge saw is a great option, though it’s pricier. Avoid using tools like jigsaws or angle grinders, as they can leave rough edges and reduce precision.

Tip: Always wear safety gear, including goggles and a dust mask, when cutting MgO boards to protect yourself from dust and debris.

 

Step 2: Positioning and Fastening

Position boards on the prepared surface, leaving a 6mm gap from walls.

Place the MgO boards on the clean, level surface you prepared earlier. Leave a 6mm gap between the boards and the walls to allow for expansion. This small detail prevents future issues like buckling or cracking.

Begin fastening from the center, spacing screws 200-250mm apart.

Start fastening the board at the center and work your way outward. This method minimizes stress on the board. Space the screws evenly, about 200-250mm apart, for a secure hold.

Place screws at least 12mm from edges and 50mm from corners.

Keep screws at least 12mm away from the edges and 50mm from the corners to avoid cracking. Use corrosion-resistant screws for durability. Avoid fastening at a 45-degree angle, as this can weaken the board’s stability.

Note: Improper fastening can lead to issues like reduced holding power or instability. Always follow these guidelines for a secure installation.

 

Step 3:Sealing and Finishing

Apply joint compound or adhesive to seams and smooth it out.

Once the boards are fastened, apply a joint compound or adhesive to the seams. Use a trowel to spread it evenly, filling any gaps. This step ensures a seamless finish and strengthens the bond between boards.

Sand the surface for a smooth finish and apply primer or sealant.

After the compound dries, sand the surface to achieve a smooth finish. Next, apply a primer to prepare the boards for painting or sealing. For added protection, especially in moisture-prone areas, use a waterproofing sealant. This step enhances the durability of your installation and protects against stains and moisture.

Pro Tip: Use high-quality paint or a transparent sealant to finish the boards. This not only improves the appearance but also extends the lifespan of your MgO board installation.

By following these step-by-step instructions, you’ll achieve a professional and durable magnesium oxide board installation. Proper cutting, positioning, fastening, and finishing are key to unlocking the full potential of MgO boards.
