6mm SPC Flooring

6mm SPC (Stone Plastic Composite) flooring is a premium-grade rigid core flooring product designed to deliver superior dimensional stability, water resistance, and wear protection. Engineered with a high-density limestone-polymer core and protected by a multi-layered structure, 6mm SPC is an optimal solution for residential and commercial spaces requiring durability, aesthetics, and ease of installation.

This article presents a comprehensive analysis of 6mm SPC flooring, covering material composition, performance metrics, compliance with international standards, engineering principles, and best practices for installation and maintenance.

What Is 6mm SPC Flooring?

SPC flooring is a multi-layered synthetic floor plank composed of natural limestone powder (CaCO₃), polyvinyl chloride (PVC), and stabilizers. A 6mm total thickness provides a balanced profile for rigidity, foot comfort, and enhanced acoustics, making it suitable for both floating and glue-down applications.

Layered Structure of 6mm SPC Flooring:

Engineering Principles

1. Dimensional Stability

• SPC’s high limestone content (>60%) and dense structure eliminate issues like expansion or contraction due to temperature or moisture changes.

• Ideal for installation in areas with variable humidity and underfloor heating.

2. Static and Dynamic Load Resistance

• Compressive strength ≥ 2000 kg/m³ resists denting from heavy furniture or equipment.

• Thickness (6mm) contributes to better acoustic dampening and subfloor leveling over minor imperfections.

3. Thermal Compatibility

• Safe for radiant heating systems (max 27°C surface temp), and low thermal expansion rate minimizes buckling risks.

Application Scenarios

Installation Guidelines

Pre-Installation Requirements

• Acclimate flooring at installation site for 48 hours

• Check subfloor flatness: max deviation 2mm per 2m span

• Moisture content for concrete subfloors: <75% RH or ≤2.5% CM

Installation Steps

• Lay underlayment (if not integrated)

• Use floating click-lock method or glue-down depending on site specs

• Maintain 8–10mm expansion gap around fixed structures

• Avoid heavy loads for 24 hours after installation

Maintenance Tips

• Cleaning: Use a dry microfiber mop or vacuum for daily care

• Deep Cleaning: Damp mop with neutral-pH cleaner, avoid abrasive chemicals

• Stain Removal: Wipe spills immediately; use alcohol-based cleaner for tough stains

• Prevention: Place felt pads under furniture; use door mats at entrances

Frequently Asked Questions (FAQs)

❓ Is 6mm SPC flooring better than 4mm or 5mm?

Yes. 6mm offers:

• Increased acoustic insulation

• Better thermal comfort

• Improved dent resistance

• More forgiving over slightly uneven subfloors

❓ Can it be used in wet areas?

Yes. 100% waterproof core allows use in kitchens, bathrooms, laundry rooms. Ensure tight seams and properly sealed perimeters.

❓ Is underlayment required?

If not pre-attached, using IXPE or EVA underlayment is highly recommended for comfort, soundproofing, and minor subfloor correction.

❓ Can SPC be installed over tiles or existing vinyl?

Yes, provided the existing floor is firm, flat, and clean. Use moisture barriers if over concrete or tiles in high-humidity areas.
