400*7mm PVC Decorative Wall Panels, PVC Wall Covering - V Sewing

Key Advantages

• Surface density of 3kg/m² provides clear reference for transport and wall load calculations
• 400mm width: Requires 2.5 panels per square meter, offering high installation efficiency
• 7mm thickness: Higher section modulus than 5mm or 6mm panels, providing greater resistance to bending deflection under vertical installation
• V-groove design: Creates uniform V-shaped recesses between panels, enhancing wall line definition and texture
• Laminated surface layer: Provides abrasion and scratch resistance, with reduced cleaning resistance
• Installation method: Tongue-and-groove joint system with visual transition provided by V-shaped grooves

Product Features

Application Scenarios

• Residential full-house walls (living rooms, bedrooms, corridors, accent walls)
• Residential wet areas (kitchens, bathroom dry zones, balcony walls)
• Commercial spaces (retail stores, beauty salons, clothing shops, dining spaces)
• Office spaces (office buildings, offices, meeting rooms, reception areas)
• Clubs and entertainment venues (private clubs, gyms, leisure centers)
• Hospitality (hotel guest rooms, hostels, apartments)

Frequently Asked Questions and Precautions

Q1: What is the visual difference between V-groove and flat seamless designs?
V-groove design creates V-shaped recesses between adjacent panels, providing clear linear divisions that enhance wall rhythm and texture. Flat seamless design pursues continuous panel surfaces with minimal visible joints. The two designs suit different interior style requirements.

Q2: What are the practical differences between 7mm and 6mm thickness wall panels?
The 7mm thickness provides higher flexural stiffness than 6mm panels. When substrate flatness deviations are significant or panel installation height is substantial, 7mm panels maintain better surface flatness and exhibit less deflection under impact.

Q3: Does the V-groove accumulate dust easily?
The V-shaped groove typically has an opening angle greater than 90 degrees, reducing dust retention. For routine cleaning, use a soft brush or dry cloth along the groove direction to remove accumulated dust. For kitchen grease-prone environments, clean the V-groove area periodically with neutral cleaner.

Q4: Can the wall panels be installed directly onto existing walls?
Yes, provided the substrate is dry, flat, solid, and free of grease, with height difference not exceeding 3mm when measured with a 2-meter straightedge. For substrates with significant flatness deviations, install leveling battens (wood or light-gauge steel) before panel installation.

Q5: Is the laminated surface scratch resistant?
The laminated surface layer is treated to provide scratch resistance for daily cleaning, soft cloth wiping, and light contact abrasion. Avoid scratching the surface directly with sharp objects (knives, keys), as this may cause irreversible scratches.

Q6: Can the panels be used in shower areas?
Panels are recommended for dry zones in bathrooms with wet/dry separation. For wet areas (shower zones), ensure all joints (horizontal, vertical, internal and external corners) are sealed with mold-resistant sealant and maintain ventilation. Prolonged water accumulation at joints may affect sealing performance.

Precautions:

• Verify substrate flatness and dryness before installation; wall moisture content should be within applicable standards
• Storage requirements: Store flat on dry ground with stack height not exceeding 1 meter; avoid edge-on storage or heavy pressure
• Use fine-tooth saw blades (tooth spacing ≤ 3mm) or score multiple times with a utility knife when cutting; coordinate cut edges with trim pieces
• Maintain consistent V-groove orientation during installation to ensure uniform gaps and continuous lines
• Reserve 3-5mm expansion gaps between panels and floor/ceiling; cover with baseboards or finishing strips
• Inspect color consistency and V-groove orientation across multiple batches before large-scale installation
• Avoid using abrasive cleaners, steel wool pads, or hard brushes on the laminated surface
• For hanging heavy objects (cabinets, picture frames, shelving units), install anchors into the substrate wall; do not fix directly to PVC wall panels
• When installation ambient temperature is below 5°C, PVC material toughness decreases, increasing the risk of edge burrs during cutting. Allow panels to acclimate at room temperature for 24 hours before installation
