Installation Guidelines

Proper installation ensures the best performance and longevity of the backing board.

Tools and Accessories Needed

  • Measuring tape and pencil

  • Circular saw or hand saw

  • Drill and corrosion-resistant screws

  • Waterproof adhesive

  • Edge sealing tape

Step-by-Step Installation Instructions

  1. Measurement and Planning: Measure the installation area accurately and mark cut lines.

  2. Cutting the Board: Use a circular saw or hand saw to cut the board to the required dimensions. Ensure edges are smooth and sealed with moisture-resistant tape.

  3. Surface Preparation: Clean and level the mounting surface to ensure optimal adhesion.

  4. Mounting: Apply waterproof adhesive on the back of the board or secure with screws/brackets. Ensure panels are properly aligned.

  5. Sealing Edges and Joints: Use moisture-resistant tape or sealant to protect edges and joints from water ingress.

  6. Finishing: Apply paint, laminate, or veneer as required for aesthetic and additional protection.


Operation Instructions

To maximize performance:

  • Avoid cutting or drilling without appropriate personal protective equipment (gloves, safety goggles, dust mask).

  • Store unused panels in a dry, covered area to prevent pre-installation moisture absorption.

  • Avoid exposure to direct flames; the backing board is fire-resistant but not flameproof.

  • Ensure proper ventilation in indoor installations to maintain indoor air quality.
