What Is SPC Flooring (Stone Plastic Composite Flooring)?
May 01, 2026
introduction
Currently, the flooring options available on the market are mainly divided into three major categories: solid wood flooring, composite wood flooring, and fiber flooring. Among these, seamless flooring has the shortest history while incorporating the most new technologies and styles. Are there other types of flooring to choose from? Today, we will introduce the latest SPC flooring, which offers waterproofing and easy installation, making it an emerging seamless flooring material in recent years.
What is SPC Flooring (Stone Plastic Composite Flooring)?
SPC flooring is a new type of flooring material primarily composed of polyvinyl chloride (PVC) and natural stone powder, making it a type of plastic flooring. With a thickness of about 6-8mm, it has high strength and wear resistance. SPC flooring also features good sound insulation and moisture resistance, as well as environmental benefits. The appearance and structure of SPC flooring are similar to wood-fiber flooring, and the installation process does not require glue, reducing formaldehyde content. Additionally, it has a long service life, making it very popular in Europe, America, Japan, and South Korea, and widely used in both residential and commercial spaces.
SPC flooring, also known as stone crystal flooring, is an upgraded version of stone plastic flooring and is considered the "moisture-proof king" among existing flooring materials! SPC stone crystal flooring is produced by extruding a PVC base material through an extruder combined with a T-shaped mold, and then bonding the PVC wear layer, PVC film, and PVC base material together through a one-time heating process. The entire process requires no glue, offering features such as zero formaldehyde, waterproofing, mold resistance, moisture resistance, fire resistance, insect resistance, and easy installation.
Structure of SPC Stone Plastic Flooring
SPC stone plastic flooring mainly consists of a UV layer, wear layer, ethylene layer, core layer, and backing layer:
UV Coating: The topmost protective layer that enhances wear resistance and stain resistance while maintaining the floor's color.
Wear Layer: Made of transparent PVC material, it primarily improves the floor's wear resistance and effectively protects it from scratches.
Ethylene Layer: Also known as the printed decorative layer, it uses printing technology to create the appearance of SPC flooring.
Core Structure Layer: Made from a mix of inorganic lime minerals, PVC composite materials, calcium carbonate, and stabilizers, this layer enhances the floor's durability, compression resistance, and deformation resistance.
Backing Layer: Increases the floor's stability, preventing expansion or contraction due to moisture or temperature changes. It often uses IXPE cushioning material for moisture resistance and sound absorption, earning it the name "soundproof layer."
SPC Stone Plastic Flooring vs. Solid Wood Flooring
Made primarily from inorganic lime minerals and PVC composite materials, it is wear-resistant, durable, 100% waterproof, and moisture-resistant, with high stability and resistance to deformation. Installation is very convenient, using a click-lock system that allows for DIY installation.
Offers a natural feel and authentic wood grain, with unique patterns on each plank. However, maintenance and installation are more complicated, requiring regular waxing and being prone to deformation.
Advantages and Disadvantages of SPC Flooring
Advantages:
Easy Maintenance and Cleaning: Made primarily from lime minerals and PVC composite materials, SPC flooring is highly waterproof and moisture-resistant, making it easy to clean. Users can simply use a damp mop, making it ideal for humid weather.
Scratch and Wear Resistant: SPC flooring has a relatively hard texture, and the wear layer protects it from scratches. You don't need to worry about pets or moving furniture scratching the floor, making it perfect for households with children or pets.
High Stability: The inclusion of inorganic lime minerals in SPC flooring provides excellent stability.
Eco-Friendly: The main raw materials of SPC flooring are renewable resources that are non-toxic and environmentally friendly. It contains no formaldehyde, lead, benzene, heavy metals, carcinogens, soluble volatiles, or radiation. It is also a reusable flooring material, truly embodying natural environmental friendliness.
Disadvantages:
High Requirements for Floor Flatness: The height difference within a 2-meter diameter must be less than 3mm. If the ground is not sufficiently flat when laying SPC flooring, the locking system may break or deform. Therefore, it is recommended for use only on flat surfaces.
Hard Texture: SPC flooring feels closer to stone, being relatively hard and slightly cold to the touch.
Applications of SPC Flooring
SPC flooring is suitable for many places, such as homes, hotels, shopping malls, and libraries. Additionally, if you want to renovate an old home on a budget or desire wood-grain flooring without the maintenance required for solid wood, SPC flooring is an excellent choice.
How to Care for SPC Flooring
Use a vacuum cleaner to remove dust, then wipe with a wrung-out damp cloth.
A damp mop can be used to clean the floor, and mild cleaning agents can be used with an appropriate amount of water.
No waxing is required.
When moving furniture, lift it rather than dragging it to avoid scratching the floor.
It is recommended to add pads or protectors to the bottom of chair and table legs, as well as cabinets, to prevent scratches.
Conclusion
SPC flooring (Stone Plastic Composite Flooring) is a new type of seamless flooring made from PVC and natural stone powder. It offers 100% waterproofing, moisture resistance, zero formaldehyde, and scratch and wear resistance. With a click-lock installation system that requires no glue, it is easy to install and suitable for humid weather and households with pets. The disadvantages are its high requirements for floor flatness and its hard texture. Overall, SPC flooring is a cost-effective choice that combines durability, eco-friendliness, and easy maintenance.
