3.5mm UV Lacquer SPC Flooring: Superior Durability and Style for Modern Homes
3.5mm UV Lacquer SPC Flooring represents a cutting-edge rigid core flooring solution that merges stone polymer composite (SPC) technology with a durable UV lacquer finish, providing an affordable yet resilient alternative to hardwood and vinyl. As one of the thinnest yet structurally sound SPC products on the market, it offers significant advantages for low-profile renovations, modular installations, and commercial upgrades.
This article explores the technical specifications, construction principles, regulatory standards, and operational guidance for selecting and installing 3.5mm UV-coated SPC flooring, especially in applications requiring dimensional stability, ease of maintenance, and aesthetic appeal.
What Is 3.5mm UV Lacquer SPC Flooring?
SPC (Stone Plastic Composite) flooring is a rigid vinyl plank that integrates natural limestone powder, polyvinyl chloride (PVC), and stabilizers. The 3.5mm thickness denotes a slim profile, ideal for low-clearance or retrofit installations. The UV lacquer layer on the surface provides a highly scratch-resistant, stain-resistant, and easy-clean finish.
Key Construction Layers
| Layer | Description |
|---|---|
| UV Lacquer Coating | Transparent top layer protecting against UV rays, scratches, and stains |
| Wear Layer (0.2–0.3mm) | Transparent PVC film providing abrasion resistance |
| Decor Film | Printed layer mimicking wood, stone, or tile aesthetics |
| SPC Core (Rigid) | Stone-polymer composite base with >60% limestone content |
| Optional Backing | May include EVA or IXPE foam for acoustic dampening (optional in 3.5mm) |
Engineering Principles
1. Dimensional Stability
The high limestone content ensures minimal thermal expansion and contraction.
Unlike traditional LVT or WPC flooring, SPC resists cupping, warping, or swelling, making it suitable for variable climates and subfloor conditions.
2. UV Lacquer Coating
The UV coating is applied via roller and cured under ultraviolet light to form a crosslinked protective layer.
Enhances resistance to:
Surface wear (Taber ≥ 6,000 cycles)
Discoloration from sunlight
Chemical staining (e.g., wine, iodine, acetone)
3. Acoustic and Thermal Behavior
While 3.5mm planks are thinner and may lack an integrated underlay, performance can be enhanced by pairing with a high-density underlayment (≥1.0mm IXPE).
Suitable for use over radiant heating systems (<27°C surface temperature) when installed with thermal-compliant adhesives or click systems.

Installation Guidelines
Subfloor Preparation
Acceptable subfloors: concrete, wood, ceramic tile, existing vinyl
Flatness tolerance: ≤2mm over 2m length
Moisture content: ≤75% RH for concrete (or ≤2.0% CM test)
Installation Methods
Floating (click-lock) or glue-down options available depending on profile
Install with expansion gaps of 5–8mm at perimeters and around fixed elements
Acclimate flooring for 24–48 hours before installation at room temperature (18–30°C)
Maintenance Recommendations
Daily cleaning: Use a soft broom, microfiber mop, or vacuum (no beater bar)
Wet cleaning: Use a pH-neutral detergent, avoid waxes or steam cleaners
Prevention: Use furniture pads, mats at entrances, and avoid dragging heavy objects
Common Applications

FAQs: 3.5mm UV Lacquer SPC Flooring
❓ Is 3.5mm SPC flooring durable enough for high-traffic areas?
While 3.5mm SPC flooring with a 0.3mm wear layer and UV lacquer is suitable for light to moderate traffic, high-traffic commercial zones should use 4–6mm SPC with AC4/AC5 wear ratings.
❓ Can it be installed in bathrooms and kitchens?
Yes. The 100% waterproof core and UV lacquer surface make it ideal for wet areas. Ensure joints are sealed and install over moisture barriers where necessary.
❓ Does the UV lacquer wear off?
Under normal use, the UV lacquer remains intact for 5–10 years, depending on foot traffic and maintenance. It prevents yellowing and enhances scratch resistance.
❓ What type of underlayment is recommended?
Use 1–1.5mm IXPE foam for better comfort, sound reduction, and subfloor imperfection absorption. For glue-down systems, underlayment is not required.
