Professional Installation Methods

1. Dry Installation (Recommended for interiors)
- Stud spacing ≤30cm
- Joint gaps: 3mm (interior)/5mm (exterior)
- Screw spacing:
- Edge distance ≥1.5cm
- Field spacing 10cm
- Top/bottom rows 5cm
2. Exterior Wall Method
- Galvanized framework (≥1.2mm)
- Install 12-15mm backer board first
- Then secure 8mm cement board
- Reinforce joints with AB adhesive
3. Wet Installation (Grout process)
- Stud spacing ≤40cm
- Staggered double-layer installation
- Add temporary bracing before grouting
- Remove supports after grout sets
7 Critical Installation Notes
- Framework Preparation
- Ensure level and stable
- Galvanized steel studs required
- Fastening Sequence
- Work from center outward
- Avoid stress concentration
- Screw Specifications
- Ceilings: 200mm spacing
- Walls: 300mm field/200mm perimeter
- Countersink 0.3mm
- Rust Prevention
- Apply rust-proof paint immediately
- Cutting Techniques
- Square holes: Pre-drill 10mm corners
- Round holes: Drill pilot holes
- Humid Areas
- Rough side out
- Moisture content <10% before tiling
- Never use cement mortar
- Joint Treatment
- Preferred: Batten system
- Exposed joints require professional sealing
