Key Ingredients:

Magnesium Oxide (MgO): Main binder providing fire resistance and structural integrity

Magnesium Sulfate (MgSO₄) / Magnesium Chloride (MgCl₂): Activator forming stable crystalline structure (sulfate-based formulations preferred for weatherproof applications to minimize chloride migration)

Reinforcement Fibers: E-glass fiber mesh, wood pulp, or mineral fibers for enhanced tensile strength and crack resistance

Lightweight Fillers: Perlite, vermiculite, or expanded clay to reduce density while maintaining strength

Weatherproof Modifiers: Silane-based water repellents and anti-aging agents to improve moisture and UV resistance

Performance Additives: Retarders, accelerators, and plasticizers to optimize curing and workability

Installation Guidelines

Surface Preparation: Ensure subfloor is clean, dry, and level (max deviation ±3mm over 2m)

Panel Layout: Plan layout to minimize cutting, ensure staggered joints for structural integrity

Fixing Method:

Mechanically fasten with corrosion-resistant screws (stainless steel or hot-dipped galvanized)
Spacing: 150-200mm along edges, 200-250mm in field
Edge distance: 10-15mm from panel edges to prevent chipping

Joint Treatment:

Tongue-and-groove panels: Apply waterproof sealant to joints before assembly
Butt joints: Leave 2-3mm expansion gap, fill with flexible sealant

Finishing: Can be directly finished with tile, vinyl, laminate, or carpet, or painted with weather-resistant coatings

FAQ

Q: What distinguishes weatherproof MGO floor panels from standard MGO boards?

A: Weatherproof MGO floor panels feature specialized sulfate-based formulations (instead of chloride) and incorporate silane-based water repellents and UV stabilizers, making them suitable for exterior applications and high-moisture environments where standard MGO boards would degrade over time. They also have enhanced dimensional stability and impact resistance specifically engineered for flooring applications.

Q: Are MGO floor panels safe for indoor use?

A: Yes, weatherproof MGO floor panels are mineral-based, non-toxic, and free from formaldehyde, asbestos, and VOC emissions, making them ideal for indoor environments including homes, schools, and hospitals. Sulfate-based formulations have ultra-low chloride content (<0.012%), eliminating concerns about corrosion or health risks.

Q: Can MGO floor panels be installed over radiant heating systems?

A: Absolutely! MGO floor panels have excellent thermal conductivity and dimensional stability, making them perfect for underfloor heating applications. Their inorganic composition resists thermal expansion/contraction, preventing warping or cracking even with frequent temperature fluctuations (-20°C to 80°C).

Q: What is the lifespan of weatherproof MGO floor panels?

A: With proper installation and maintenance, weatherproof MGO floor panels can last 50+ years, significantly longer than traditional wood-based flooring (15-20 years). Their inorganic structure resists biological degradation, corrosion, and weathering, ensuring long-term performance with minimal maintenance.

Q: Can fireproof Mgo wallboard be painted or decorated?

A: Yes, fireproof Mgo wallboard can be painted or decorated using standard paints and finishes. It can also be textured or wallpapered to suit different design preferences.

Q: How does fireproof Mgo wallboard perform in terms of impact resistance?

A: Fireproof Mgo wallboard has good impact resistance, making it less prone to damage from accidental impacts compared to some other building materials. However, it is still recommended to take necessary precautions to avoid excessive force on the walls.

Q: Is fireproof Mgo wallboard resistant to termites or other pests?

A: Fireproof Mgo wallboard is highly resistant to termites and other pests, thanks to its inorganic composition. This makes it a suitable choice for regions where termite infestations are common.

Q: Can fireproof Mgo wallboard be used as a structural element?

A: Fireproof Mgo wallboard is not typically used as a structural element on its own. It is commonly used as a non-load-bearing partition or cladding material.
