Product Introduction
Magnesium Oxide Sulfate Board Water Resistant Wall Cladding Panels
Magnesium Oxide Sulfate Board, or MgSO₄ Board for short, is a high-performance building material.It's mainly made from magnesium oxide, magnesium sulfate, fiberglass mesh, plus lightweight fillers like perlite and bamboo fiber.It stands out for great waterproof performance and being eco-friendly.It's perfect for wall panels in damp areas and exterior building decoration.
Advantages of Magnesium Oxide Sulfate Board Water Resistant Wall Cladding Panels
1. Waterproof Performance
Magnesium sulfate has a stable chemical structure, so it can effectively keep water out. The board's water absorption rate stays below 8% to 10%. Unlike traditional magnesium oxychloride boards (MgCl₂ boards), MgSO₄ boards totally fix the "efflorescence" issue-so they won't absorb moisture from the air and corrode metal keels. For example, one brand of MgSO₄ board stays structurally stable even after being soaked in water for a long time; it doesn't deform or lose strength at all.
2. Fire Resistance and Safety
This board is a Class A1 non-combustible material, and its fire resistance lasts more than 270 minutes. When it's exposed to high temperatures, a dense oxide layer forms on its surface to block heat transfer. That's why it's great for places with strict fire safety requirements, like hospitals, schools, and commercial complexes.
3. Environmental Friendliness and Health
It doesn't contain any harmful stuff like asbestos, formaldehyde, or benzene-so it meets international environmental standards, such as ISO 9001 and SGS certification. Its production process uses less energy, and it's recyclable too. That's why it's one of the top choices for green building materials.
4. High Strength and Durability
A 12mm thick board has a flexural strength of 15 to 20MPa, and an 18mm thick one can reach 20 to 25MPa or even higher-way stronger than regular gypsum boards. Its surface is sanded, so it's super flat and can stand up to impact well. It's perfect for high-traffic areas.
5. Corrosion and Pest Resistance
Thanks to magnesium sulfate's chemical properties, it doesn't corrode steel. And since it's made of inorganic materials, it naturally resists mold, termites, and other biological damage. That makes it especially good for damp coastal areas or basements that are prone to rotting.

Manufacturing Process of Magnesium Oxide Sulfate Board Water Resistant Wall Cladding Panels
1. Composite Reinforced StructureThe board adopts a multi-layer composite process:
-
Base Layer: Cementitious materials of magnesium oxide and magnesium sulfate provide strength and waterproofness;
-
Reinforcement Layer: Alkali-resistant glass fiber mesh (with better alkali resistance than ordinary glass fiber) is embedded inside the board to form a three-dimensional support network, preventing cracking;
-
Surface Treatment: Some products are pre-coated with waterproof coatings (e.g., UV paint) or sealants before leaving the factory to further improve weather resistance.
2. Dimensions and SpecificationsCommon thicknesses range from 3mm to 30mm, with standard dimensions of 1220×2440mm and a maximum customizable size of 1220×3050mm. Edge designs include flat edges, tongue-and-groove edges, or shiplap edges, facilitating quick installation and reducing the risk of joint leakage.

Installation Process and Precautions O Magnesium Oxide Sulfate Board Water Resistant Wall Cladding Panels
Base Treatment
Ensure the wall base is flat and dry (moisture content ≤10%), free of oil and dust. For light steel keels, check the keel spacing (recommended ≤600mm) and verticality.
Board Installation
Bonding Method: Apply special adhesive (e.g., modified cement adhesive or epoxy resin adhesive) evenly on the base with a thickness of 2-3mm. After pasting the board, tap it firmly with a rubber hammer to ensure no hollowing.
Mechanical Fixing Method: Fix with self-tapping screws (length ≥ board thickness + keel thickness + 10mm) at a spacing of 150-200mm, 15-20mm from the board edge. The screw heads should be slightly embedded 1mm into the board surface.
Joint Treatment
Reserve 3-5mm gaps between boards, fill with elastic sealant (e.g., neutral silicone sealant), and paste alkali-resistant glass fiber mesh (width ≥50mm) to prevent cracking.
Add an additional layer of mesh cloth at internal and external corners to enhance crack resistance.
Surface Decoration
Can be directly plastered with putty, painted with latex paint, or tiled with ceramic tiles or stone. For tile installation, use flexible tile adhesive to avoid falling off due to thermal expansion and contraction.
For exterior wall applications, it is recommended to spray waterproof and breathable coatings (e.g., acrylic-based) on the board surface to improve weather resistance.
Construction Safety
Wear dust masks when cutting boards to avoid inhaling dust;
The connection between light steel keels and boards must meet seismic design requirements, using galvanized screws or rivets to ensure strength.
