Directions for Use

1. Substrate Preparation
  • Surface must be clean, dry, and free of oil, grease, dust, or loose material.

  • Ensure smooth concrete surfaces before placing the strip.

2. Application Guidelines
  • Place in the center of the concrete structure.

  • Maintain concrete cover:

    • Reinforced concrete → 8 cm minimum cover each side

    • Unreinforced concrete → 15 cm minimum cover each side

  • Apply a thin layer of adhesive on the bonding surface. Allow 5–20 minutes drying time before pressing.

  • Do not nail or shot-fire directly to concrete.

  • At corners and intersections, butt-join strips tightly. No hot welding required.
