Repair of Truck Tarps with Hot Gas Welding Devices

Required Materials:

• AKU hot gas welding device
• AKU welding nozzle (flat or round nozzle, depending on application)
• Repair PVC (tarp material matching the existing tarp)
• AKU pressure roller
• Scissors or cutter
• Cleaning agent (e.g., isopropanol)
• Protective gloves

Alternatively, it’s best to use a corresponding hot gas welding device set from AKU, tailored for truck tarps, tents, pools, etc.

Step-by-Step Guide:

1. Preparation of the Repair Site

• Thoroughly clean the damaged area to remove dirt, oil, or other contaminants.
• Allow the tarp to dry, as moisture can affect the welding bond.
• Cut the repair piece from PVC so that it generously covers the damaged area (at least 2-3 cm overlap).

2. Setting Up the Hot Gas Welding Device

• Set the device to the optimal temperature for PVC welding (approx. 300–450 °C, depending on the material).
• Use a suitable nozzle (e.g., a flat nozzle for large-area repairs).

3. Preheating the Tarp and Repair Piece

• Preheat the damaged area and the PVC patch material with hot air until the material becomes slightly soft.

4. Welding Process

• Place the repair piece on the damaged area and slowly heat along the edge with the hot gas welding device.
• Simultaneously, firmly roll over the seam with a pressure roller to ensure an even connection.
• Continue the welding process step by step until the entire repair piece is securely welded to the tarp.

5. Cooling and Inspection

• Allow the welded area to cool for at least 10-15 minutes.
• Then check for tightness and strength by gently pulling on the repaired area.

6. Optional Reinforcement

• If necessary, apply a second weld seam to make the connection even more resistant.
• Alternatively, an additional PVC layer can be applied for reinforcement.

Conclusion for the Professional User:

With a professional hot gas welding device, tarps, such as truck tarps, can be quickly and professionally repaired.
This method ensures a durable, weather-resistant, and long-lasting connection that significantly extends the lifespan of the tarp and saves costs.
