1. Core Advantages of SPC Flooring
SPC (Stone Plastic Composite) flooring, also known as stone-plastic composite flooring, has become a popular choice for indoor floor decoration in recent years. Its core advantages mainly include waterproof performance, durability, stability, and comfort.
1.1 Waterproof Performance
The core structure of SPC flooring is a composite of stone powder and polyvinyl chloride (PVC), providing 100% waterproof capability.
- Thickness range: 4mm–8mm
- Water resistance: Can withstand 24-hour water immersion without significant swelling or deformation
- Suitable environment: Kitchen, bathroom, basement, and other humid areas
Compared with traditional solid wood flooring, SPC flooring will not warp or mold in humid environments.
1.2 Wear and Scratch Resistance
SPC flooring usually has a wear-resistant layer (UV coating or reinforced layer), significantly enhancing scratch and wear resistance.
- Wear layer thickness: 0.3mm–0.7mm
- Wear resistance grade: AC3–AC5 (suitable for high-traffic areas in homes and commercial spaces)
- Scratch resistance test: Can withstand daily furniture friction and pet claws
1.3 Dimensional Stability and Deformation Resistance
Due to the low expansion coefficient of the stone-plastic composite material, SPC flooring maintains excellent dimensional stability under temperature and humidity changes.
- Thermal expansion coefficient: approx. 5 × 10⁻⁵ /℃
- High-temperature tolerance: Can withstand 60℃ for long-term use
- Shrinkage/expansion resistance: Remains flat under ±40% humidity changes
1.4 Comfort and Sound Insulation
Although SPC flooring is known for its hardness, with proper underlayer design and locking structure, it provides good foot comfort and certain sound insulation.
- Surface hardness: approx. 60–70 Shore D
- Walking noise reduction: 10–15 dB (compared with tiles)
- Thickness impact on comfort: 6–8mm thickness balances durability and comfort
In summary, SPC flooring offers waterproof, scratch-resistant, stable, and comfortable advantages, making it highly practical for residential, office, and commercial spaces.
2. SPC Flooring Installation Guide
SPC (Stone Plastic Composite) flooring is easy to install due to its stable structure, waterproof and wear-resistant properties. Correct installation is crucial for longevity and comfort.
2.1 Pre-Installation Preparation
1. Subfloor Treatment
- The subfloor should be flat, dry, solid, without cracks or protrusions
- Flatness standard: ≤ 2 mm / 2 m
- Moisture requirement: Cement-sand subfloor ≤ 2%, wooden subfloor ≤ 12%
2. Environmental Adaptation
- SPC flooring should be placed indoors for 48 hours before installation to adapt to temperature and humidity
- Room temperature: 18–28℃, humidity 40–60%
3. Tool Preparation
- Measuring tools: tape measure, level
- Cutting tools: flooring saw, cutter
- Installation aids: rubber mallet, wooden wedges, pull bar
2.2 Installation Method
SPC flooring mainly uses floating click-lock installation, without glue or nails.
