Frequently Asked Questions and Precautions
Q1: What are the practical differences between 8mm thickness and 6mm or 7mm thickness wall panels?
The 8mm thickness provides flexural stiffness approximately 2.4 times that of 6mm and 1.5 times that of 7mm. For applications with significant substrate flatness deviations, installation heights exceeding 3 meters, or walls expected to withstand impact, the 8mm panel offers greater resistance to deflection and impact.
Q2: Does the V-groove design affect the panel's water resistance?
The V-groove is a decorative recess; the tongue-and-groove joint structure of the panel body remains sealed. Under normal use conditions, the grooves do not allow water penetration into the wall. For wet zone applications (shower areas), apply mold-resistant sealant along the V-grooves for additional sealing.
Q3: Is the product truly "zero formaldehyde"?
No formaldehyde is added as a raw material component. PVC resin itself contains no formaldehyde, and the lamination layer and adhesives use formaldehyde-free systems. Specific formaldehyde emission values can be verified through test reports, typically meeting E0-level or relevant international standards.
Q4: Can the panels be installed directly onto tiled or painted existing walls?
Yes, after evaluating substrate adhesion and flatness. Clean and degrease tile surfaces. Remove peeling sections and sand old painted surfaces. When height difference does not exceed 3mm measured with a 2-meter straightedge, direct installation is possible. For significant deviations, install leveling battens first.
Q5: Is the laminated surface scratch resistant? How is daily cleaning performed?
The laminated surface provides scratch resistance for soft cloth wiping and daily cleaning. Clean with a soft cloth dampened with water or neutral cleaner. Avoid using steel wool pads, abrasive cleaners, or hard brushes, which may leave visible scratches on the laminated surface.
Q6: Is the product suitable for export?
The 400*8mm specification is a standard wall panel size in several international markets. Use export-grade corrugated cartons with pallet wrapping for packaging. Confirm the destination country's fire rating requirements and formaldehyde emission standards, and provide corresponding test reports for import compliance.
Precautions:
Verify substrate flatness, dryness, and solidity 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. Due to the weight of 8mm panels, place wooden spacers under bottom layers
Use fine-tooth saw blades (tooth spacing ≤ 3mm) or electric jigsaw tools with minimum power of 500W when cutting. Cover 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
For kitchen wall installations, maintain minimum distance of 300mm from cooking appliances to avoid direct high-temperature exposure
For hanging heavy objects (cabinets, water heaters, 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. Allow panels to acclimate at room temperature for 24 hours before installation
For export orders, confirm packaging specifications, test reports, and certification documents to meet destination country import requirements
