Installation Process & Precautions 

1. Installation Preparation

Tool List: Tape measure, chalk line, electric saw (carbide blade), utility knife, electric drill, level, safety gear;

Auxiliary Material Preparation: 316 stainless steel self-tapping screws (corrosion-resistant), specialized waterproof sealant, glass fiber mesh tape, putty (only for non-decorative coatings);

Substrate Treatment: Light steel keel spacing ≤400mm, surface flat, dry, and oil-free. Keels in humid environments must be hot-dip galvanized.

 

2. Key Installation Steps

Cutting & Coating Protection: Avoid damaging the surface coating during cutting. For thin boards, score the coating side with a utility knife; for electric saw cutting, place the coating face down to minimize scratches.

Board Fixation: Install vertically. Screw spacing: 200-250mm (board edges), 300-350mm (board center). Screws must be ≥15mm from board edges (to prevent coating detachment), with heads slightly recessed ≤0.5mm.

Joint Treatment: Reserve 3-5mm gaps between boards, filled with specialized waterproof sealant (for humid environments). Decorative coated boards can use color-matched sealant directly, no additional putty needed.

 

3. Core Precautions

Coating Protection: Avoid collisions with sharp objects during installation to prevent scratches or damage to the coating.

Fastener Selection: Must use 316 stainless steel screws; never use ordinary iron nails (prone to rust and coating bulging).

Humid Environment Treatment: For bathrooms, basements, etc., apply waterproof glue to the contact surface between keels and boards to enhance sealing.

Cutting Dust: Wear a mask during cutting and ensure ventilation to avoid inhaling magnesium oxide dust.
