Focusing on "FAQ: Can I Paint Directly Over Fiber Cement Boards?", this article breaks it down one by one from the four levels of design basis, material matching, construction control and acceptance evidence, and provides parameters, practices and checklists that can be directly implemented for the design, procurement, construction and supervision teams to compare and implement.

1. Preparation of tools and accessories

Construction efficiency and quality largely depend on the availability of tools: laser levels, electric screwdrivers, cutting tools, caulking tools and inspection rulers should be present in advance. Auxiliary materials must match the plate and keel system and cannot be temporarily substituted.

2. Layout and typesetting

First play the elevation line and keel positioning line, and then layout according to the board module to avoid narrow strips at the corners. The positions of lamps, air vents, inspection openings and switch sockets must be determined on the layout drawing to reduce on-site drilling and rework.

3. Fixing and installation

• The screw spacing is carried out according to the system requirements, and the nail head is slightly lower than the board surface.
• The panels should be installed at staggered seams, and the joints must not fall on the same keel.
• Set reinforced keels at door and window openings and corners.
• Heavy equipment uses independent lifting points and is not directly fixed to the panel.

4. Finished product protection

After installation is completed, avoid cross-construction contamination and collision, and maintain ventilation in humid environments. Use a hole opener when opening holes in the subsequent process and reinforce them to prevent the board surface from cracking.

5. Process inspection

• Recheck the elevation, flatness and verticality after each process is completed.
• Check screw fixings, joint treatments and reinforcement measures.
• Keep photos and inspection records of concealed works.
• If problems are discovered, correct them on the spot without entering the next process.

Installation quality comes from process control. The four links of tools, wiring, fixing and protection are all in place, and rework will naturally be reduced.
