Is SPC Flooring 100% Waterproof?
SPC flooring is widely promoted as waterproof, making it a popular choice for kitchens, bathrooms, coastal homes, and commercial interiors. However, many buyers still ask whether SPC flooring is truly 100% waterproof or just water resistant. This article clearly explains what waterproof means in the context of SPC flooring and what users should realistically expect.
Short Answer: Yes, SPC Flooring Is 100% Waterproof
SPC flooring has a fully waterproof core made from stone powder and PVC. This core does not absorb water, swell, or warp when exposed to moisture. Unlike wood or laminate flooring, SPC flooring remains dimensionally stable even when water is present on the surface.
What Makes SPC Flooring Waterproof?
1. Stone-Based Rigid Core
The SPC core is composed primarily of limestone powder combined with PVC and stabilisers. This composition prevents water absorption and ensures the floor does not deform due to moisture exposure.
2. Non-Absorbent Structure
SPC flooring has a dense, non-porous structure that blocks water penetration, even during prolonged exposure to humidity or spills.
3. Protective Wear Layer
The top wear layer seals the surface, preventing water from reaching the decorative layer and protecting against stains and surface damage.
What 100% Waterproof SPC Flooring Does NOT Mean
- It does not make the subfloor waterproof
- It does not prevent moisture problems caused by leaks below the floor
- It does not eliminate the need for proper installation
While the flooring itself is waterproof, trapped moisture beneath the floor can still cause issues if subfloor preparation is poor.
Where SPC Flooring Performs Best as a Waterproof Solution
- Kitchens and dining areas
- Bathrooms and powder rooms
- Laundry rooms
- Living rooms and bedrooms
- Coastal and high-humidity homes
- Commercial interiors
SPC Flooring vs Laminate (Waterproof Comparison)
- SPC Flooring: Fully waterproof core, no swelling or warping
- Laminate Flooring: Water resistant only, prone to swelling when wet
Installation Still Matters
Even though SPC flooring is waterproof, correct installation is essential. Expansion gaps, flat subfloors, and proper locking prevent water from becoming trapped and ensure long-term performance.
Maintenance Tips for Waterproof SPC Flooring
- Clean spills promptly
- Avoid standing water for extended periods
- Use damp mopping with mild cleaners
- Maintain expansion gaps and edge protection
Frequently Asked Questions (FAQ)
1. Can SPC flooring be submerged in water?
The flooring itself will not be damaged, but prolonged submersion is not recommended due to subfloor concerns.
2. Is SPC flooring safe for bathrooms?
Yes, SPC flooring is suitable for bathrooms when installed correctly.
3. Will water damage SPC flooring joints?
Properly locked joints resist water, but standing water should still be removed.
4. Is SPC flooring better than vinyl for waterproofing?
SPC offers better dimensional stability and rigidity than flexible vinyl.
5. Does waterproof SPC flooring need sealing?
No, additional sealing is not required for the flooring itself.
