🔧 Step-by-Step Installation Guide
1. Wall Prep (The Foundation)
- Remove old tiles/loose paint • Fill cracks with cement putty
- Apply waterproof membrane (mandatory behind showers)
- Pro Tip: Use Witop’s Leveling Strips if wall unevenness >3mm
2. Layout Planning
- Mark stud locations • Avoid aligning joints with plumbing
- Dry-fit panels → Adjust for outlets/pipes
- Pattern Tip: Run panels vertically → height illusion in small baths
3. Cutting Openings
- Measure outlets/valves → Add 1/8″ gap
- Use jigsaw with fine-tooth blade for WPC/PVC
- Safety: Wear N95 mask when cutting
4. Adhesive Application
- Apply construction adhesive (Witop GripMax™) with notched trowel
- Pattern: Vertical lines (improves bond)
- Work in 3×4 ft sections → panels slide into place
5. Panel Installation
1. **Start at corner:** Press firmly into adhesive
2. **Use spacers:** Maintain 1/8" gap at floor/ceiling
3. **Check level:** Every 3rd panel
4. **Secure edges:** Brad nails at top/bottom (hidden under trim) 6. Sealing & Trims
- Apply 100% silicone at:
- All corners
- Panel-to-fixture joints
- Floor/ceiling transitions
- Install Witop SnapTrim™ covers (hides edges + expansion gaps)
⚠️ 5 Critical Mistakes to Avoid
- Skipping waterproof membrane → Causes wall rot
- Butting panels tight → Leave 1/8″ gaps for expansion
- Wrong adhesive → Use only panel-rated construction glue
- Sealing before 24 hrs → Let adhesive fully cure
- Ignoring vent fans → Moisture buildup = mold risk
