Product Introduction
What Is Magnesium Oxide Board for MGO Flooring Boards
A specialized inorganic high-performance flooring substrate/underlayment board made of magnesium oxide as the core raw material, designed exclusively for floor systems. It replaces traditional floor base materials (cement mortar leveling layer, gypsum board, density board, calcium silicate board) and solves the pain points of traditional flooring substrates such as poor water resistance, flammability, easy deformation, formaldehyde release, and heavy weight. It is widely used in civil, commercial, and prefabricated building floor systems, especially for scenarios with high requirements for fire safety, waterproofing, and environmental protection.
Advantages of Magnesium Oxide Board for MGO Flooring Boards
1. High Bearing & Impact Resistance (Core for Flooring)

Magnesium Oxide Board for MGO Flooring Boards
Core Composition & Structural Design (Flooring-Specific Optimization)
MGO flooring boards are not ordinary MGO decorative boards-their formula and structure are tailored for floor bearing, impact resistance, and flatness requirements, with key optimizations in raw materials and structural layers:
1. Core Raw Materials (High-Strength & Waterproof Formula)
- Main Cementitious Material: High-purity active magnesium oxide (MgO, purity ≥90%) – higher purity than ordinary MGO boards, ensuring denser crystal structure and stronger bearing capacity after hydration reaction.
- Gelling Agent: Modified magnesium sulfate solution (priority) or low-halogen magnesium chloride solution – anti-halogen return technology is the core, avoiding surface halogenation (efflorescence) caused by moisture, which is critical for floor surface flatness and decorative layer adhesion.
- Reinforcement System: Multi-layer alkali-resistant glass fiber mesh cloth (3–5 layers embedded) + polypropylene fiber (short fiber doping) – dual reinforcement to improve flexural strength, impact resistance, and crack resistance, preventing fracture under long-term floor load.
- Flooring-Specific Fillers: Quartz sand (high hardness), talc powder (improves flatness), fly ash (reduces weight), and waterproof modifiers/anti-cracking agents – optimize water absorption rate, dimensional stability, and surface wear resistance.
- Surface Treatment Layer: Dense inorganic waterproof coating (bottom layer) + sanding finish (top layer) – enhances adhesion with floor adhesives and decorative layers (wood flooring, tiles, PVC).
2. Structural Design (Flooring-Dedicated Layered Structure)
Unlike single-layer ordinary MGO boards, MGO flooring boards adopt a three-layer composite structure to balance strength, weight, and flatness:
- Bottom Waterproof Layer: Dense inorganic modified layer, water absorption rate ≤8%, prevents ground moisture from penetrating the board;
- Middle Core Bearing Layer: High-density MgO crystal layer with fiber reinforcement, bearing capacity ≥1.5MPa, withstands furniture load and pedestrian impact;
- Top Flat Finish Layer: Sanded and coated surface, flatness error ≤2mm/2m, ensuring seamless laying of floor decorative layers.
3. Production Process (Precision Molding for Flooring)
- Formula Batching: Flooring-specific ratio (MgO: gelling agent: filler = 1:0.6–0.8:1.2–1.5) with strict control of moisture content (10–12%);
- High-Pressure Forming: Continuous press molding (pressure ≥15MPa) to eliminate internal pores, ensuring board density uniformity;
- Constant Temperature Curing: 48–72h constant temperature (35–45℃) and humidity (60–70%) curing to complete hydration reaction, avoiding post-curing deformation;
- Precision Cutting & Sanding: CNC cutting to standard sizes, double-sided sanding to ensure flatness, and surface waterproof coating treatment;
- Quality Inspection: Focus on testing bearing strength, water absorption rate, flatness, and anti-halogen return performance before delivery.

Magnesium Oxide Board for MGO Flooring Boards
Installation & Construction Guidelines (Flooring-Specific Steps)
MGO flooring boards support dry construction (mainstream) and wet construction (for heavy-duty floors), with simple steps and high efficiency. Below is the standard dry construction process (most widely used):
1. Pre-Construction Preparation
- Base Treatment: Clean the original ground (cement floor, wood floor, light steel keel), remove dust, oil, and debris; fill ground cracks >2mm with cement mortar; ensure ground flatness error ≤3mm/2m;
- Material Preparation: MGO flooring boards (matching thickness), galvanized self-tapping screws (3.5×25mm), MGO special floor adhesive, alkali-resistant glass fiber mesh tape, inorganic floor joint compound;
- Tool Preparation: Woodworking saw, electric drill, level ruler, rubber mallet, tape measure.
2. Core Construction Steps
Step 1: Board Layout & Cutting
Layout according to the floor area, stagger joints (staggered by ≥300mm, like brick laying) to avoid cross joints;
Cut boards to size with a woodworking saw, reserve 2–3mm expansion joints between boards and between boards and walls (for thermal expansion and contraction).
Step 2: Base Laying (Two Methods)
Method 1: Direct Laying (On Flat Cement Ground)
Apply MGO special floor adhesive on the ground (spread evenly with a notched trowel, coating thickness 2–3mm);
Lay MGO flooring boards, press firmly with a rubber mallet, ensure no hollowing;
Fix with self-tapping screws (screw spacing 200–250mm, screw head recessed 0.5–1mm into the board surface).
Method 2: Keel Laying (On Uneven Ground/Light Steel Structure)
Install light steel keels (spacing 300–400mm) or wooden keels (anti-corrosion treated) on the ground;
Lay MGO flooring boards on the keels, fix with self-tapping screws (screw spacing 150–200mm, fix at keel positions);
Fill gaps between keels with sound insulation cotton (optional, for sound insulation).
Step 3: Joint Treatment
Fill board joints with inorganic floor joint compound, smooth with a scraper;
Paste alkali-resistant glass fiber mesh tape on the joints (width 50mm), press firmly to avoid bubbling;
Apply a second layer of joint compound after the first layer dries, sand flat with sandpaper.
Step 4: Surface Decoration Layer Laying
After the joint compound is completely dry (24–48h), lay various floor decorative layers directly:
Wood Flooring/Composite Flooring: Lay underlayment (optional) + glue/nail the flooring;
Ceramic Tiles/Marble: Apply tile adhesive on the MGO board surface, lay tiles (no need for cement mortar);
PVC Flooring/Linoleum: Clean the MGO board surface, apply PVC special adhesive, lay the flooring;
Carpet: Lay carpet underlayment + fix the carpet.
3. Key Construction Precautions
- Avoid Long-Term Soaking: Although waterproof, do not immerse the board in water for a long time (e.g., floor accumulated water for >24h);
- Expansion Joints: Must reserve 2–3mm expansion joints between boards and walls, and 10–15mm expansion joints at floor corners (to prevent thermal expansion cracking);
- Fastener Requirements: Use galvanized/stainless steel self-tapping screws to prevent rust; screw heads must be recessed to avoid damaging the decorative layer;
- Underfloor Heating Special: For underfloor heating systems, use MGO flooring board, and lay the decorative layer after the board is completely cured (72h);
- Storage: Store boards in a dry, ventilated place, stack flat (≤10 layers), avoid direct sunlight and rain.
