How To Repair A Poly Tank

So you need to repair a poly tank?   Or you can buy a new one.  However, if that tank is a large, like the tank below, a replacement can cost over $10,000.

$ 10,000 is a lot of money to spend to repair a poly tank especially if the problem is a small crack.  You can repair any poly tank quickly, easily and permanently.

Skeptical?  Skeptics are the reason why we have a money-back guarantee.  If our products do not meet your performance expectations, we will refund your purchase price.  Simply return the kit.  So far, after having sold thousands of kits, we have not made a refund.  

Now that we have that issue out of the way, you’ll ask, “How do we do the impossible?”  We use the Bonding Poly Process (patent pending) to stop the on a poly tank.

What’s the secret of the Bonding Poly Process?  It’s how we combine

  • our polymer-enhanced, Surface Insensitive Structural Cyanoacrylate,
  • our standard Activator/Accelerator,
  • our Poly Prep
  • and heat 

Your result, every time, will be hard to believe.  When I first used the process to bond a poly (a polyurethane bumper cover), I didn’t believe the result.  Over the next several months, I repeated the Bonding Poly Process again and again.   Testing was done with every polymer I could find.   Success was 100%.  And, even when I abused the result, the bond didn’t fall apart.  I asked myself again and again, why did it take me sixteen years and three months to figure out the process?

Watch the video below on bonding Delrin® to Polypropylene to preview the process.  I will summarize the step-by-step process on repairing your tank below.

Bonding Poly Process

To bond polymers, you need one of poly kits.  Our Basic Poly Kit (shown below) includes;

  • an SI Structural Cyanoacrylate,
  • our standard Activator/Accelerator,
  • our Poly Prep
  • and a detailed step-by-step instruction sheet.  We’ve been told that our instruction sheet is easy to understand and follow.

Depending on the size of your tank, or the number of repairs you need to make, you may need to purchase a larger kit.  A link to purchase a Basic Poly Kit appears below.

Instructions on how to repair a poly tank appear below.

Bonding Poly Process TM (BPP) (Patent Pending)Use the Bond Poly Process described below to repair a poly tank.  Tech-Bond Solutions herein grants the right to use the Poly Bonding Process with the purchase of a Poly Bonding kit.

  • Make sure the surface is clean. Aggressively rough the surface aroung the crack.
  • Begin by saturating both edges the crack or tear with our Poly Prep.  Let Poly Prep dry
  • Spray one edge with the Activator/Accelerator.  (Alternatively, use (2) from below.)
  • Let the A/A dry.
  • Take a blow dryer or a heat gun and WARM both edges/surfaces. Don’t overheat.  Poly surface(s) should be very warm, but not hot.  T
  • Apply an SI structural adhesive to the edge opposite (while warm) from where the AA was sprayed.
  • Bring the two edges together and firmly press for fifteen to twenty seconds.
  • Take the hair dryer or heat gun and warm the seam for thirty seconds.
  • (2) Or you can also apply the prime with the Poly Prep, warm the two edges of the break or tear, then apply the SI adhesive to one surface, press the surfaces together and spray the seam with A/A. Hold firmly for 10 seconds then warm for 20 sec.

Repairing tanks

Tech-patches are a solution for the holes and cracks that occur in tanks, barrels or containers.  Not only will Tech-Patches permanently seal a metal tank.  With the Bonding Poly Process (patent pending), Tech-Patches will permanently seal holes and/or cracks on any plastic container regardless of the size.    Replacing these containers cost owner/operators/businesses millions of dollars.  Tech-Patches are a viable long term solution.  Impossible you say?  That’s what we heard in the early days of the Bonding Poly Process (patent pending).  

One of the reasons why these cracks and holes have defied solution is that these tanks and containers have thin walls, a physics problem.  That thinness simply does not provide the surface area needed for an adequate repair.  Available patches will not support these thin walls as they flex.  Fiberglass and other common patches won’t work because they crack when flexed.  Tech-patches are flexible, will stretch when needed and they bond to almost all plastic or metal containers.   

From this point forward, we will use the terms container to refer to tanks, barrels, buckets, silos, anything that holds … contents.

There are three additional problems when a repairing a container:

  • Weather.  Many, if not most containers, are outside and have to withstand weathering.  Standard adhesives and patches simply don’t handle weather well.  
  • Resistance to chemicals.  Tanks hold water, gas, oil, other hydrocarbons and many other chemicals.  Adhesives and common patch material do not hold up long-term to hydrocarbons and many other chemicals.
  • Permanence.  Many, if not most, adhesives provide temporary solutions.  If you’re going to have to replace the container soon why put off the ordeal off?  Patches need to be permanent.

Strengthening the repair on your poly tank. 

First option to strengthen the repair is to add layers of SI structural adhesive.

  • Prime the surface area where the reinforcement is to be applied with the Poly Prep.  Let the Poly Prep dry.
  • Warm the area with a heat gun or hair dryer.  You want the surface to be warm to the touch, but not hot. 
  • Apply beads of structural adhesive to the primed area.  Spread the adhesive as thinly as possible.
  • Spray the Activator/Accelerator.  
  • Repeat at least once.  There may be substantial heat when you spray the accelerator.  Be careful.

Note:  Once the structural adhesive dries, it will be harder than most metals.  You have substantially strengthened your repair.  Repairs or bonds can take up to 30 days to cure.

Second option to strengthen the repair is to apply a patch.

  • Prime the surface area where the patch is to be applied with the Poly Prep.  Let the Poly Prep dry.
  • Warm the area with a heat gun or hair dryer.  You want the surface to be warm to the touch, but not hot. 
  • Apply beads of structural adhesive to the primed area.  Do not spread.
  • Have the patch cut to fit.  Lay the patch on the beads of adhesive
  • Apply beads of the adhesive to the patch extending the adhesive 1/2 inch beyond the patch.  Spread the adhesive as thinly as possible.
  • Spray with the Activator/Accelerator. 
  • Repeat 
  • Run a bead of adhesive on the seam, all the way around.  Do NOT spread.
  • Spray with the Activator/Accelerator.

You have solved your problem.

Note:  Our structural adhesives are impervious to ALL petroleum products.  Our structural adhesives are NOT impervious to strong acid, caustic solutions, nitro-methane, acetone and MEK.
