Step 1: Wall Inspection & Preparation • Ensure wall is dry (moisture content ≤8%), flat, free of loose dust and oil • Raw wall: Level with putty first, flatness tolerance ≤3mm/2m • Renovation: Remove all loose layers, sand smooth • Uneven wall: Install wood battens (30×40mm) or light steel battens for    leveling, batten spacing 300-400mm, fix with expansion screws • Wet environment (bathroom): Waterproof treatment and batten installation recommended Step 2: Measurement & Layout Planning • Precisely measure wall width and height • Design layout based on color pattern, determine each panel position • Seamless series: Pay special attention to vein direction and joining    sequence, trial-fit on floor first recommended • Mark horizontal and vertical reference lines on wall with laser level • Pre-plan positions for outlets, switches and conduits Step 3: Panel Cutting • Mark cutting lines on panel surface according to actual dimensions • Cut with UV surface facing up using electric panel saw to prevent edge chipping • Moderate cutting speed, not too fast (prevent panel overheating and deformation) • Lightly sand cut edges with 240-grit sandpaper to remove burrs • Pre-cut openings for outlets and switches using hole cutters • Clean panel surface dust after cutting Step 4: Adhesive Application • Apply structural adhesive to back of panel in "S" or rectangular pattern • Adhesive bead width: approx. 8-10mm, spacing: approx. 10-15cm • Apply adhesive 2cm from panel edges to prevent overflow • For enhanced bonding, apply adhesive to both panel back and wall/batten    surface (double-sided application method) • After application, wait 1-2 minutes until adhesive surface slightly skins    before bonding (better results) Step 5: Panel Mounting • Align panel with reference lines, install from bottom to top, left to    right (or from center to sides) • First panel is critical — must repeatedly confirm level and plumb with level tool • After positioning, use press roller to roll evenly from center outward,    expelling air bubbles • Use rubber mallet to gently tap and fine-tune position (must complete    within 3 minutes) • Leave 0.5-1mm gaps between panels for thermal expansion • If using batten method, reinforce with nail gun through panel side edges Step 6: Click-Lock Joining (Lock System Series Only) • For click-lock/tongue-and-groove series, align male groove with female groove • Insert at 15-degree angle, then press flat to lock • Lock series requires no gaps — expansion gaps are built into the lock design • Gently push to confirm locks are fully engaged and secure Step 7: Edge Finishing • Install metal trim profiles:   - External corner → L-profile external corner trim   - Internal corner → Internal corner trim   - Panel-to-panel joint → T-profile strip or H-profile clip strip   - Exposed panel edge → U-profile edge trim   - Ceiling junction → Top edge trim   - Floor junction → Skirting base trim • Fix trims with silicone sealant or clip method • Seal wall-to-ceiling/floor junctions with neutral silicone sealant • Ensure trim colors coordinate with panel colors Step 8: Cleaning & Acceptance • Remove PE protective film (only after all installation is complete to    avoid construction scratches) • Wipe surfaces with soft dry or slightly damp cloth to remove adhesive    residue and dust • For stubborn adhesive marks, gently wipe with alcohol pad (do not use    acetone or strong solvents) • Inspection checklist:   ✓ All joints flat and even   ✓ All trim profiles secure and aesthetic   ✓ No scratches or damage on panel surfaces   ✓ Pattern veins correctly aligned (seamless series)   ✓ Outlet and switch openings properly fitted • Ready for immediate use upon acceptance, no waiting required ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Daily Maintenance: • Daily cleaning: Wipe with soft dry or slightly damp cloth • Stubborn stains: Neutral cleaner + soft cloth, then wipe with clean water cloth • Do not use: Steel wool, strong acid/alkaline cleaners, acetone or strong solvents • Protection: Avoid direct impact or scratching with sharp hard objects • Glossy panels: Regularly wipe with soft dry cloth along grain direction    to maintain shine ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Important Notes: 1. Panels should rest flat in installation environment for 24 hours before     installation to acclimatize 2. Recommended installation temperature: 5°C - 35°C, relative humidity ≤70% 3. Structural adhesive full curing: 24-48 hours. Avoid impact or vibration before curing 4. Wear cotton gloves throughout glossy panel installation to prevent fingerprints 5. Panels cannot be bent. Curved walls require special flexible panels or heat-bending 6. Confirm color codes and vein directions before installation to avoid errors 7. SPC (SP) base material recommended for wet environments like bathrooms 8. For hanging TVs or heavy items on feature walls, pre-embed mounting hardware at batten positions 9. Professional installation team recommended for large-scale projects 10. Keep spare panels for future repair and replacement ```
