Manufacturing Process of Magnesium Oxide Panels
The manufacturing process of MgO boards is more complex than it seems. It usually involves several steps to ensure high-quality products. Here are the steps that are followed during its manufacturing procedure:
Mixing
First thing first, mix all the raw materials and additives. Add water to form a homogenous mixture or slurry.
Molding
The slurry is then poured into molds of desired shape and thickness. The molds are designed to ensure uniformity and consistency across all the boards. This molding process is very complex as it involves handling intricate materials.
Pressing
After molding, the materials in the molds are pressed to remove any water. Pressing compacts the mixture, and it is crucial for various reasons;
To achieve the desired strength and density
Make the boards more robust and durable.
Curing
After that, the pressed boards are left to cure. Depending on the manufacturing method, curing might happen in a controlled environment. However, curing can also be done at natural temperature. Allowing the chemical reactions to finish will produce a long-lasting board.
Finishing
The last step is very crucial. Once cured, the boards are sanded and trimmed to create smooth edges and surfaces. They then undergo a quality inspection before being packaged and sent. This process is critical to giving the boards a definite shape. It also helps give a refined edge and strengthen them.
What is Magnesium Oxide Wallboard Used for
Interior Applications
Like plywood or drywall, MgO boards can be used for interior and exterior applications. In the interior, construction professionals use them for walls and ceilings. They are also excellent as flooring substrates in kitchens, bathrooms, bedrooms, and living rooms.
MgO boards are durable and provide sound insulation. That is one of many reasons people use them for regular interior walls.
You can use them in bedrooms for a quieter and more fire-resistant environment. They also have many advantages, one of which is moisture resistance. That is why you may find them in bathrooms and kitchens.
MgO boards can also improve sound insulation within a building. They reduce noise transmission between rooms and floors. That is why they are suitable for use in residential and commercial buildings' walls, floors, and ceilings.
Exterior Applications
Because of their versatile nature and numerous benefits, MgO boards are often used for exterior wall sheathing. Construction professionals also use MgO boards as an underlayment for exterior siding materials. The reasons are many!
MgO boards add structural strength and impact resistance to exterior walls. They can also be applied as an underlayment for roofing materials. The reason- they provide fire resistance and extra structural support.
MgO boards are very strong, making them great for use as structural panels in walls, floors, and roofs. In load-bearing walls, MgO boards can replace traditional materials, such as plywood or OSB. In such locations, MgO boards provide superior fire resistance and durability. That is why they are great for constructing exterior walls in residential and commercial buildings.
They are especially great in areas prone to extreme weather conditions or requiring high fire safety standards.
MgO Boards for Trim
You can use MgO boards for trim and fascia. They are also used to finish edges and create decorative elements around the building's windows, doors, and corners. This use takes advantage of MgO boards' weather-resistant qualities. They don't rot, warp, or get damaged by insects, ensuring they last a long time.Furthermore, MgO boards used as trim need less maintenance than traditional wood trim. This makes them an attractive and practical choice for exterior detailing.
MgO Boards as Fascia
When installed along the roof's edges, MgO boards serve as fascia boards covering the rafters' ends. In this role, MgO boards withstand exposure to the elements. And all that without deteriorating, ensuring durability and longevity, Additionally, they give the roof a neat, polished look, improving the building's appearance. Using MgO boards for fascia, homeowners can achieve a durable and appealing exterior finish. Plus, it requires minimal maintenance.
MgO Boards as Flooring Substrate

How to Cut Magnesium Oxide Board
MgO Board Cutting Guide: Tools and Techniques
To cut magnesium oxide boards, use a circular saw with a thin carbide blade for clean and precise cuts. Ensure you wear safety goggles, gloves, and a dust mask to protect yourself from dust particles.
Circular Saw
Anyone who has dealt with MgO boards will tell you that the best way to cut them is using a circular saw with a thin carbide blade. In other words, it is a saw with a blade that is reduced in thickness, ranging from 3/32 inch to 1/8 inch.
The blade is made from carbide, a compound of carbon and metal. It is one of the hardest and most resistant metals, which is why manufacturers use it for cutting tools, padlocks, and more. Also, thin carbide blades offer a clean and precise cut with minimal chipping.

Jigsaw
Besides the circular saw, there are other types of saws, like jigsaws or handsaws. However, they are not good choices for cutting MgO boards. Here's why! While a jigsaw is good for making curved cuts, it might be slower than a circular saw. Additionally, it may require more finishing work on the edges compared to a circular saw.
The choice of saw also depends on the thickness of your boards and their application. Construction professionals usually use jigsaws for cabinet openings, curved patterns, and intricate cutouts. On the other hand, a circular saw is better for construction projects, such as ones involving MgO boards. Also, circular saws are more powerful. You can use them to cut through thicker materials.
Handsaw
A handsaw might be the worst choice for cutting MgO boards. It is inefficient and time-consuming. If you have ever used a handsaw, you know what I'm talking about. A handsaw requires significant effort and multiple strokes to cut through MgO boards, so the process is very slow and laborious.
Using a handsaw can easily result in rough and uneven cuts. Magnesium oxide boards are not very cheap, so choosing the right tool is paramount! You do not want to waste the boards on inefficient tools. Also, with handsaws, there is an increased risk of breakage.
MgO boards can be a bit delicate, and the pressure from a handsaw can easily cause them to crack or chip, especially around the edges. Lastly, MgO boards can be a bit stubborn, and if your handsaw bucks or slips, it could lead to an accident. Not worth the risk!
Angle Grinder with Masonry Blade
While I personally never used an angle grinder for cutting MgO boards, I've seen others do so, and it is messy! Unlike a jigsaw or handsaw, an angle grinder with a masonry blade can definitely cut through MgO boards.
However, using it will mostly likely result in rough cuts. They are designed for rough cutting and are not the best tools for cutting MgO boards. Additionally, you have less control over the board and the cut with an angle grinder. It makes it challenging to achieve a straight line. So, using an angle grinder is only an option if you absolutely do not have access to a circular saw.
Step 1: Prepare the Materials
Obviously, your first step is to measure and mark the cut line on the MgO boards with a pencil and a T-square. Make sure that the line is straight and visible so it is easier to cut it. Secure the board on a stable surface. Now, it is also time to put on safety goggles, gloves, and a mask. Inhaling dust particles can result in health problems, so I urge you to get one as soon as possible.
Step 2: Adjusting the Blade
I assume that you have installed the carbide blade in your circular saw. Your next step is to adjust the blade's depth so it is slightly deeper than the board. This will allow you to get a clean cut without excessive strain on the saw.
Step 3: Cutting
Now, it's time to align the saw with the marked cut line. Start the saw and let it reach full speed before making contact with the board. Then, gently push the saw along the cut line, applying steady pressure. Never force the saw; let it do its job! If you maintain a consistent speed and keep the saw straight, you will avoid chipping and uneven cuts.
Magnesium Oxide Boards vs. Other Materials
It's safe to say that magnesium oxide boards have several advantages over other construction materials, based on the benefits previously mentioned.
Gypsum
Although both gypsum and magnesium oxide boards are eco-friendly, the former poses more harm to people because its fly ash releases toxins when cut.
Portland Cement
Portland cement lacks water-resistant and fire-suppressing capabilities. Plus, MgO leaves a smaller carbon footprint compared to cement. And although Portland cement is recognizably strong, MgO has a higher rating on impact strength even though it is considerably lighter in weight.
Plywood
MgO is undoubtedly safer than plywood as a construction material. Plywood is not flame resistant and could quickly spread fire it is not water resistant, making it susceptible to moisture that could grow mould and vulnerable to water damage.
Oriented Strand Board (OSB)
When it comes to safety, MgO ranks higher than OSB. The OSB releases formaldehyde, a dangerous toxin. It is not fire resistant nor is it resistant to moisture and termites.
Installation Method for Magnesium Oxide Board Flooring Using Joists
Preparation
-
Materials and Tools
Gather the necessary materials, including MgO boards, wooden or metal joists, screws, expansion bolts, a level, moisture barrier (optional), and installation tools such as a drill, hammer, etc.
-
Surface Cleaning
Before installation, ensure that the floor surface is clean and level. Remove any debris and make sure the surface is smooth. If the surface is damp, it's advisable to lay down a moisture barrier to improve the floor's resistance to moisture.
Installing The Joists
-
Determine Joist Layout
Plan the joist layout based on the floor dimensions. Typically, the joist spacing should be between 40-60 cm (16-24 inches). Use a level to ensure the joists are installed evenly, which is crucial for a level floor. The choice between wooden or metal joists should be based on the environmental conditions and load requirements.
-
Securing the Joists
Place the joists in their designated positions and use expansion bolts to secure them to the floor. Ensure that all joists are at the same height to avoid uneven flooring. If using wooden joists, consider applying a protective coating on the areas in contact with the floor to extend their lifespan.
-
Reinforcing the Joists
Install cross-bracing between the main joists to further stabilize the structure. These cross braces should be placed perpendicular to the main joists, with spacing that matches the MgO board dimensions. This ensures that the edges of the boards are fully supported.
Laying the MgO Boards
-
Cutting the Boards
Measure and cut the MgO boards to fit the floor layout and joist spacing. Ensure the edges of the boards are cut cleanly to allow for tight seams and secure installation.
-
Securing the Boards
Place the cut MgO boards onto the joists and secure them with specialized screws. The screws should be spaced 20-30 cm (8-12 inches) apart, with even distribution along the edges and across the center of the boards. Make sure the screws are flush with the surface of the board to avoid any protrusions.
-
Handling Expansion Gaps
Leave a small expansion gap (typically 3-5 mm) between the boards to accommodate potential expansion and contraction due to changes in temperature and humidity. Fill these gaps with sealant or caulk to prevent dust and moisture from penetrating.
Surface Finishing
-
Leveling Check
Once the boards are installed, use a level to check the evenness of the floor. Adjust as necessary to ensure there are no noticeable high or low spots.
-
Installing the Top Layer
Depending on your requirements, you can add a decorative top layer such as vinyl flooring, tiles, or hardwood on top of the MgO boards. This layer not only enhances the aesthetic appeal of the floor but also adds an additional protective layer, prolonging the floor's lifespan.
