SPC Flooring FAQs

SPC flooring has become a major trend in recent years, gaining popularity among homeowners and interior designers alike. To help you understand this innovative material better, we’ve compiled answers to the most frequently asked questions about SPC flooring — including its key features, advantages, and practical maintenance tips.

1. What Is SPC Flooring？

SPC (Stone Plastic Composite) flooring is an innovative material made from a combination of limestone powder and PVC resin. It blends the strength of stone with the flexibility of vinyl, offering exceptional durability, water resistance, and slip resistance. These qualities make SPC flooring suitable for both residential and commercial spaces

2. How Long Does SPC Flooring Last?

High-quality SPC flooring can last over 10 years, while lower-grade options may show signs of wear within 2–3 years. The lifespan depends on the product quality, the environment it’s installed in, and how well it’s maintained.

3. Is SPC Flooring Durable?

Yes, SPC flooring is extremely durable. Its wear-resistant top layer protects against scratches, scuffs, and everyday wear, while its waterproof, moisture-proof, and fire-resistant properties make it ideal for high-traffic areas.

4. Is SPC Flooring Made of Plastic?

SPC flooring is composed mainly of stone powder and PVC (polyvinyl chloride). While PVC is a type of plastic, SPC’s high stone content (around 60–70%) gives it a texture and density closer to natural stone than traditional vinyl or plastic flooring.

5. Is SPC Flooring Toxic?

High-quality SPC flooring is non-toxic and safe for home use, especially those that meet strict EU safety standards. Certified products are free from harmful substances such as formaldehyde and heavy metals, making them safe for both adults and children.

6. Does SPC Flooring Contain Formaldehyde?

No. Quality SPC flooring does not contain formaldehyde. It’s made primarily from natural stone powder and PVC resin without the use of glue, meaning it does not emit formaldehyde during or after installation. Always choose reputable brands for guaranteed safety.

7. Does SPC Flooring Contain Plasticizers?

Good-quality SPC flooring typically avoids the use of plasticizers. These additives are found mainly in low-quality PVC products. For a healthier home environment, choose trusted brands that provide testing certifications and clear material disclosures.

8. Is SPC Flooring Waterproof?

Yes. SPC flooring is completely waterproof — it won’t swell, warp, or deform even with prolonged water exposure, making it ideal for kitchens and bathrooms.

9. Can You Mop SPC Flooring with Water and Detergent?

Yes. You can safely clean SPC flooring with a damp mop or cloth, and mild neutral detergents if needed. Avoid using strong acidic or alkaline cleaners.

10. Is Thicker SPC Flooring Better?

Not necessarily. The standard SPC flooring thickness is around 5–6mm, but thicker doesn’t always mean better. Durability depends more on the locking system and underlayment quality.
For example, IXPE underlayment (common but thin) can age or deform under temperature changes, while PU+PET underlays offer better comfort, sound insulation, and waterproof protection.

11. How Much Does SPC Flooring Cost?

Prices vary depending on brand, thickness, and quality. On average, SPC flooring costs between HK$18–HK$60 per square foot in Hong Kong.

12. Do You Need Expansion Gaps for SPC Flooring?

Yes. Leave a 5–8mm expansion gap around the room to prevent warping or buckling caused by temperature or humidity changes.

13. Does SPC Flooring Require Glue?

SPC flooring comes in two types:

• Click-lock installation – no glue required, suitable for DIY installation.
• Glue-down installation – requires adhesive on the subfloor.

For best durability, choose flooring with a patented locking system, such as Valinge 5G, which ensures long-term stability.

14. Can SPC Flooring Be Installed on Uneven Floors?

No. Uneven subfloors can cause long-term damage, such as cracking at the joints. The floor should be levelled within a 2mm tolerance before installation. Self-levelling compounds are recommended for the best results.

15. Does SPC Flooring Get Mouldy?

The flooring itself won’t mould, but if moisture is trapped beneath the surface, mould may develop on the subfloor or along walls. Ensure proper installation and ventilation to avoid this issue.

16. Does SPC Flooring Expand?

SPC flooring is highly stable and won’t expand due to moisture. However, under extreme heat, it may experience slight thermal expansion. Use curtains or blinds to block direct sunlight in areas exposed to strong heat.

17. Can SPC Flooring Be Replaced in Sections?

Yes. Click-lock SPC flooring allows for partial replacements. Damaged planks can be removed and replaced individually — though it’s best to have a professional handle the repair.

18. How to Clean and Maintain SPC Flooring?

SPC flooring is very easy to maintain. Simply wipe with a damp cloth or mop. For stubborn stains, use a mild detergent. Avoid steel brushes or sharp tools that may scratch the surface.

19. What Is a Repeating Pattern in SPC Flooring?

The repeating pattern refers to how often the same printed design appears on the planks.

• Lower-quality (China-made) flooring usually has 5–6 repeating patterns.
• Premium European brands use random grain technology with 10 or more variations, creating a more natural, high-end appearance.

20. What Are the Drawbacks of SPC Flooring?

• Requires an even subfloor for best performance.
• Feels harder underfoot compared to wood.
• Less natural appearance than real wood.
• May slightly deform under extreme temperatures.

21. Can You Install SPC Flooring Yourself?

Yes — click-lock SPC flooring is DIY-friendly. However, glue-down types require professional installation to ensure proper alignment and longevity.

22. Does SPC Flooring Come in Herringbone Patterns?

Yes. Many European SPC flooring brands offer herringbone patterns.
These floors use alternating left and right locking planks that create the signature zigzag look. However, installation is more complex and requires precise alignment, so professional installation is recommended.
Note: herringbone SPC floors typically result in about 20% more material waste, so both material and labour costs will be higher.

23. Can SPC Flooring Be Installed Over Existing Tiles?

Yes, it can — but surface preparation is key. Ensure the tile surface is clean, flat, and level before installation to avoid unevenness or gaps.
