03 Apr 3 Steps to Install MgO Boards in Modular Houses
Table of Contents
When building modular houses, MgO boards are very useful. These boards are strong and can handle tough conditions easily. Unlike OSB boards, MgO boards don’t catch fire quickly. They can take high heat without breaking apart. They are also tough against impacts and stay strong under pressure. This makes them a good choice for long-lasting use. Plus, they are eco-friendly, so they help the environment.
To make them work well, you must install MgO boards correctly. Following steps carefully helps them fit and work as needed. Ready to learn how? Let’s begin!
Key Takeaways
Getting ready is important. Collect tools like a tape measure, saw, and screws first.
Make sure the surface is clean and dry. A smooth surface helps the MgO boards stick better.
Measure everything carefully and decide the layout. Good measurements make the boards fit tightly and stay in place.
Attach the boards using screws spaced equally apart. This keeps them steady and stops them from moving later.
Seal and level the edges to finish. Sealing protects from water and makes the boards last longer.
Step 1: Getting Ready to Install MgO Boards
Before putting up MgO boards, being ready is important. A little work beforehand makes the job easier and the results better. Let’s go step by step.
Collect Tools and Supplies
You’ll need some tools and supplies to begin. Here’s a simple list:
Important tools: Get a measuring tape, saw, drill, and screws. Use a carbide-tipped saw blade for cutting MgO boards.
Needed supplies: Have MgO boards, adhesive, and fasteners ready. A strong urethane adhesive works best for sticking the boards.
Having everything prepared saves time and avoids extra trips to the store.
Check and Clean the Surface
The surface must be clean and smooth for a good installation. Take these steps:
Check for bumps, dirt, or wet spots. These can weaken how the MgO boards stick.
Make sure the surface is dry, clean, and flat. Use a leveling compound if there are uneven areas.
Pro Tip: Push the boards firmly onto the surface for a strong hold. Follow the drying time given by the manufacturer for the best results.
Measure and Plan the Layout
Good measurements and planning make a big difference. Here’s what to do:
Measure the area carefully and mark where each board will go.
Leave a small gap, about 6mm, between the boards and walls. This stops problems from temperature changes.
Line up the boards with the framing or joists for extra strength.
Planning ahead helps the MgO boards fit well and stay in place for a long time.
By doing these steps, you’re ready for success. Good preparation makes installation easier and helps the boards last for years.
Step 2: Install MgO Boards

Now that you’ve prepared everything, it’s time to install MgO boards. This step is where your planning pays off. Follow these steps to ensure a smooth and professional installation.
Position the Boards
Start by placing the boards in the right spots.
Begin in one corner of the room and work your way across systematically. This approach keeps everything aligned and avoids gaps.
Make sure the boards line up with the joist layout or framing. This alignment provides extra support and ensures the boards stay secure over time.
Tip: Double-check the alignment as you go. A small adjustment now can save you from bigger issues later.
Secure the Boards
Once the boards are in position, it’s time to fasten them.
Use screws or fasteners to attach the boards securely. Space the screws about 20-30 cm (8-12 inches) apart along the edges and across the center of each board. This even distribution helps maintain the structural integrity of the boards.
Ensure the screws sit flush with the surface of the boards. If they stick out, they could interfere with the finishing process or create weak points.
Proper fastening is key to long-term stability. MgO boards are dense, so this step ensures they stay firmly in place without shifting or warping.
Cut and Adjust Boards
Not every board will fit perfectly as-is. You’ll need to make some adjustments.
Use a saw to cut the boards to fit edges, corners, or other tricky areas. A carbide-tipped blade works best for clean cuts.
Maintain proper spacing for expansion gaps, typically around 6mm. These gaps allow the boards to expand and contract with temperature changes, preventing cracks or buckling.
Pro Tip: Measure twice before cutting. It’s better to take your time than to waste a board due to a mistake.
By following these steps, you’ll install MgO boards with precision and confidence. A well-installed board not only looks great but also performs better in the long run.
Step 3: Finishing the Installation
You’re almost done! The final step is all about ensuring the MgO boards look great and last for years. Let’s dive into the finishing touches.
Level the Surface
Before you move on to sealing, take a moment to check the surface.
Look for any uneven areas. Run your hand across the boards or use a straightedge to spot bumps or dips.
If you find any irregularities, fix them. Apply a leveling compound to smooth out the surface. Follow the manufacturer’s instructions for the best results.
Pro Tip: A level surface not only looks better but also ensures the boards stay stable over time.
Seal and Treat the Boards
Sealing the joints and edges is crucial for durability. Here’s how you can do it:
Use a high-quality sealant to fill the gaps between boards. This step prevents moisture from seeping in and causing damage.
Pay extra attention to the edges. A well-sealed edge protects the boards from wear and tear.
Once sealed, it’s time to prepare the surface for its final look. Whether you’re painting or applying another finish, make sure the boards are clean and dry. A protective top layer not only enhances the appearance but also adds an extra shield against daily wear.
Why It Matters: Finishing steps like sealing and treating the boards improve their durability. They also help the boards handle temperature changes and resist damage over time.
By following these steps, you’ll ensure your MgO boards are ready to perform and look their best. A little extra effort now will save you time and money in the future.
Installing MgO boards doesn’t have to be complicated. Let’s quickly recap the three steps:
Preparation: Gather your tools, clean the surface, and plan the layout.
Installation: Position, secure, and adjust the boards with care.
Finishing: Level, seal, and treat the boards for durability.
Why MgO Boards? They’re durable, fire-resistant, and eco-friendly. Plus, they’re easy to install when you follow these steps.
Take your time, follow the process, and you’ll achieve a professional finish that lasts for years. You’ve got this! 😊
FAQ
What are MgO boards made of?
MgO boards are made from magnesium oxide, a natural mineral. They also include other materials like fiberglass mesh and perlite. This combination makes them strong, fire-resistant, and eco-friendly.
