Repair Metal Pipes/Tanks | 2″ Wide Patch

These Tech Patch Kits will repair metal pipes/tanks | 2″ wide patches provide strong, lasting repairs. These patches use our proven Polymer Bonding Process. The process works by preparing the surface of the tank to form a molecular bond between the patch and the tank. The result is a permanent repair that will not peel, crack, or fall off.

You can use these Tech Patches on tanks that hold fuel, water, or chemicals. They bond to steel, copper, iron, cement, aluminum, etc., metal tanks. Each kit includes the patch and chemicals needed to make the repair. A heat gun is required.

Instructions

Step-by-Step Process for Permanent Bonding of a Tech Patch to a Metal, PVC or Cement Tank or Pipe.

Surface Prep – surface prep is critical

1. Prepare the Surface
   Start by roughing the damaged area of the tank. For metal surfaces, sand thoroughly to a near-white or polished finish. This is critical — failure to do so is a known fail point.
   Next, clean the area completely to remove any dust or residue.

2. Apply the Accelerator
   Ligthly spray the Accelerator evenly across the prepped tank surface.
   Allow it to dry fully. Do not apply the Bonding Agent while the surface is still wet.

Application Process

1. Apply the Bonding Agent
   Using small, tight concentric circles, apply the Bonding Agent directly to the patch, not to the tank. The coat must be thorough but not heavy.
   Run a bead of the Bonding Agent along the edge around the entire perimeter.

2. Position the Patch
   Grab the patch by the corners and press it firmly onto the tank.
   Immediately use the glue squeegee to apply pressure from the center outward.
   This step is essential — you’re working to squeeze out every bit of excess Bonding Agent.
   Excess adhesive is the #1 cause of bond failure.  Trapped adhesive = failed bond.

3. Apply Heat
   Warm the patch until you reach approximately 120 °F (49 °C) — just below “hot” by touch.
   Within seconds, the patch will begin to generate heat on its own. The patch will become hot, reaching a temperature around 135 °F (57 °C), give or take.
   You’ll feel the heat for several minutes — that’s your confirmation the bond is activating.

4. Top Coat Application (Ventilation or a fan required)
   When the patch cools down to about 120 °F (49 °C), apply three coats of the Bonding Agent on top of the patch.  For each coat, run beads of the Bonding Agent on the patch.  Use the glue squeeqee (once) to spread the adhesive for each layer.  Again three layers of adhesive are required.
   Spray a light mist of the Activator/Accelerator to the Bonding Agent.  A light mist is all that is needed.

Final Check

1. Final Check
   Inspect carefully. There must be no folds or creases — they will cause the bond to fail.
   In most cases, the repair is complete in under 30 minutes. After the thirty minutes, the tank can be refilled.

Application Notes

• The 2″ width is ideal for narrow cracks, seams, and hard-to-reach or curved surfaces.

• Once bonded, the patch becomes rigid and durable, designed to withstand heat, pressure, and movement.

• Tech Patches are proven in the field. When you follow these directions, they work — every time.

Material Strength

Each Tech Patch is made from PTFE-coated e-glass fabric.
This high-performance composite combines:

• The strength and stability of e-glass,

• The chemical, heat, UV, and abrasion resistance of PTFE,

• A low-friction surface that handles demanding environments.

Critical Fit Reminder

Your patch or wrap must extend at least one inch beyond the entire perimeter of the damage.
This is non-negotiable — failure to extend the patch far enough is a known fail point.
