How to Repair Silicon Appliances

MEDICFX Appliance Repair Instructions

🔧What You’ll Need:

  • MEDICFX Repair Kit or Repair Gun

  • Isopropyl Alcohol

  • Sticky tape (approx. 4cm wide)

  • Sewing pins (with heads)

  • Hairdryer (optional – for faster curing)

  • Plastic bottle or hard foam block (for support)

Step-by-Step Repair

  1. Clean the Area
    Wash the appliance with hot water. Wipe the tear or cut with isopropyl alcohol to ensure the surface is clean and ready for bonding.

  2. Set Up the Appliance
    Lay it flat on a clean surface. For sleeves, wrap them around a plastic bottle or place them over a foam block to keep their shape.

  3. Position Tape (Optional Method A)
    Place a strip of sticky tape under the tear, sticky side facing up. This will support the repair from behind.

  4. Mix Silicone
    Use a 1:1 ratio (100/100) as per your MEDICFX repair kit instructions — or load the cartridge into the repair gun.

  5. Apply Silicone
    Gently spread silicone into the tear or cut using a spatula or gloved finger.

  6. Close and Secure the Edges
    Press both sides of the tear together. Use sewing pins to hold the edges in place while it cures.

  7. Let It Cure
    Leave the repair to set for at least 1 hour. You can speed this up with a hairdryer (on low heat).

  8. Inspect and Repeat if Needed
    If gaps or dents remain, repeat the process — clean, reapply, and secure again.

Extra Tips:

  • Foam Block Method (Optional Method B)
    You can skip the tape if using a foam block. Push pins through the appliance into the foam to hold the shape securely during repair.

  • For Added Strength
    If the area will be under tension or stretch, embed a strip of mesh into the silicone on the back side of the appliance for reinforcement.
