- Addtime: 2025-09-19 / View: 161
If you’re considering a kitchen flooring upgrade, you might be wondering, “Can I install SPC flooring over my existing kitchen floors?” The answer is often yes, but key factors—including when direct installation isn’t recommended—must be considered. Below is a concise guide aligned with CWWIN Floor’s SPC product durability and practicality.
Compatibility with Existing Flooring Types
Use the table below to quickly check if your existing kitchen floor is suitable for direct SPC installation, and which CWWIN models work best:

Installation Prerequisites
|
Not Recommended If
|
|
Tile Floors
|
WaterShield Pro SPC, UltraDurable X SPC
|
– Tiles are firmly attached (no cracks/looseness)- Surface is clean (no grout buildup/grease)- Uneven grout lines (over 1/8 inch) are smoothed with leveling compound
|
– Over 30% of tiles are cracked- Subfloor has moisture damage (mold/soft spots)
|
|
Linoleum/Vinyl Floors
|
ClickFlex Plus SPC
|
– No tears, peeling edges, or bubbling- Grease (near stovetops/sinks) is removed with neutral degreaser
|
– Floor is over 15 years old (brittle)- Adhesive contains asbestos (pre-1980 installations)
|
|
Wood Floors
|
ThermoGuard Max SPC
|
– No warping, cupping, or gaps over 1/4 inch- Squeaks are fixed (to avoid noise transfer)- Vapor barrier is installed
|
– Floor is water-damaged (swollen planks)- Termite infestation is present- Significant seasonal movement (widening gaps)

Subfloor Preparation: Key Steps for CWWIN Products
Proper prep maximizes the lifespan of CWWIN’s SPC lines, especially high-traffic models like HeavyTraffic Pro SPC. Focus on three core steps:
1. Cleanliness (Kitchen-Specific)
• Sweep/vacuum debris (prevents gaps under HeavyTraffic Pro SPC).
• Degrease with pH-neutral cleaner (avoids plank shifting near stovetops).
• Air-dry for 24+ hours (critical for WaterShield Pro SPC’s moisture resistance).
2. Leveling (Meet CWWIN’s Standard)
All CWWIN models require subfloors flat within 3/16 inch over 10 feet (stricter for rigid UltraDurable X SPC):
• Use a 10-foot straightedge to spot high/low areas.
• Sand high spots; fill low spots (over 1/4 inch) with latex-based leveling compound (cure 48 hours).
3. Moisture Testing (Non-Negotiable for Kitchens)

Installation Considerations: Aligned with CWWIN Specs
4. Acclimation
CWWIN’s SPC (HeavyTraffic Pro SPC, ThermoGuard Max SPC) needs 48–72 hours in the kitchen (65–85°F, 30–50% humidity) to avoid warping. Store unopened boxes away from heat vents/sunlight.
5. Expansion Gaps
Leave 1/4–3/8 inch gaps around perimeters (walls, cabinets) and transitions. For kitchens over 200 sq ft, add gaps every 30 feet (e.g., under islands). Use CWWIN foam spacers (included with ClickFlex Plus SPC kits).
