Can SPC Flooring Be Installed Over Tiles?
Many homeowners and contractors ask whether SPC flooring can be installed directly over existing tiles during renovation projects. The short answer is yes — SPC flooring can be installed over tiles, provided certain conditions are met. This guide explains when it is possible, what preparation is required, and when it should be avoided.
Is It Possible to Install SPC Flooring Over Tiles?
Yes, SPC flooring can be installed over ceramic or porcelain tiles as a floating floor. Thanks to its rigid core and click-lock system, SPC flooring can bridge minor surface imperfections and reduce the need for tile removal, saving time and cost.
Conditions That Must Be Met Before Installation
1. Tiles Must Be Firm and Secure
All existing tiles must be well bonded to the subfloor. Loose, cracked, or hollow tiles can cause movement and noise issues.
- Tap tiles to check for hollow sounds
- Fix or remove loose tiles before installation
2. Tile Surface Must Be Flat
Large grout lines or uneven tiles can affect plank locking and floor stability.
- Fill deep grout lines with levelling compound
- Ensure surface variation is within acceptable limits
3. Floor Height Clearance Must Be Considered
Installing SPC over tiles increases floor height, which may affect doors, transitions, and skirting.
- Check door clearance before installation
- Plan trims and transitions in advance
4. Clean and Dry Surface Is Required
Dust, grease, and moisture can interfere with installation quality.
- Clean tiles thoroughly before laying SPC
- Ensure the surface is completely dry
Do You Need Underlay Over Tiles?
Underlay is not always required if the SPC flooring already includes an attached backing. However, an acoustic or moisture barrier underlay may be recommended to improve sound control and comfort.
When You Should NOT Install SPC Over Tiles
- If tiles are loose or unstable
- If grout lines are very deep and uneven
- If moisture problems exist beneath the tiles
- If floor height increase creates functional issues
Benefits of Installing SPC Flooring Over Tiles
- No need for tile removal
- Faster renovation process
- Reduced dust and debris
- Cost-effective flooring upgrade
Installation Tips for Best Results
- Allow SPC flooring to acclimatise before installation
- Maintain proper expansion gaps around walls
- Use appropriate trims for a clean finish
- Follow manufacturer installation guidelines
