Surface Preparation

Proper surface preparation is critical for ensuring a secure, long-lasting heat shrink installation. Follow these steps carefully:

  • 1

    Clean and Dry Surfaces

    Ensure all surfaces are completely free of moisture, dust, and debris. Use isopropyl alcohol for best results.

  • 2

    Remove Contaminants

    Eliminate any oils, grease, or chemical residues that could prevent proper adhesion.

  • 3

    Check for Sharp Edges

    Inspect connectors and surrounding areas for any burrs or sharp edges that could damage the heat shrink tubing.
