What You'll Learn
Eternabond tape can be used to fix a punctured grey tank
EternaBond tape is a super-strong adhesive tape used by RVers to repair leaks and seal cracks in their vehicles. It can be used to fix a punctured grey tank, but it is important to note that this is a permanent fix, and the tape will be difficult to remove.
EternaBond tape uses a patented "MicroSealant" technology, which is designed to stop non-pressurized leaks and adhere to surfaces permanently. The result is a waterproof and airtight sealant that doesn't dry out in the sun and doesn't shrink back to reveal holes, cracks, or gaps. The tape comes in various widths, from 2 inches to 48 inches, and each roll has a UV-protected backing.
Before applying EternaBond tape, it is recommended to thoroughly clean and sometimes prime the surface area. The company provides detailed installation instructions, which should be followed to ensure proper application. The proper technique for patching a tank is to drill a hole on both ends of the crack to prevent the crack from growing, then clean the surface and apply the tape.
While EternaBond tape can provide a temporary fix for a punctured grey tank, it is important to note that it may not be suitable for all situations. Some users have reported success in patching hard-to-reach areas, such as the tops of holding tanks, even without properly cleaning the surface. However, for a more permanent solution, it may be necessary to replace the tank or consider other repair methods, such as welding.
Additionally, it is important to consider the toxicity of the repair material, especially if it comes into contact with consumable water, as is the case with freshwater tanks. While some users have expressed concerns about the toxicity of EternaBond tape, others have suggested that minor exposure during brief periods of use may not be a significant issue.

It can also fix a cracked seam on a black tank
Eternabond tape can be used to fix a cracked seam on a black tank. However, it is important to note that some people have expressed doubts about its effectiveness, recommending other methods such as welding or using epoxy. Nevertheless, there are also successful accounts of using Eternabond tape for similar purposes, suggesting that it can be a viable option for repairing cracked seams on black tanks.
When using Eternabond tape to repair a cracked seam on a black tank, it is essential to prepare the surface properly. This may involve cleaning the area around the crack with a solvent like acetone and roughening the surface using sandpaper or a drill to create a better adhesion for the tape. It is also recommended to use a sealant in conjunction with the tape to ensure a stronger bond and create a watertight seal.
One suggested method for repairing a cracked seam on a black tank using Eternabond tape is to first identify the ends of the crack by wiping the area with a solvent like lacquer thinner. Once the crack is visible, use a drill bit to stop-drill both ends of the crack, creating a small hole at each end. Then, use a cutting tool to create a groove between the two holes, connecting them. Fill this groove with a suitable sealant, such as 3M 5200, and allow it to cure for several days.
After the sealant has cured, apply a patch of Eternabond tape over the repaired area, ensuring that it covers the groove and the surrounding area. Seal all the edges of the tape with another layer of sealant and allow it to cure completely. Finally, fill the tank with water to test for any leaks. This method combines the strength of the sealant with the reinforcement of the Eternabond tape, creating a durable repair for the cracked seam on the black tank.
While Eternabond tape can be used for repairing cracked seams on black tanks, it is important to consider the specific tank material and the toxicity of the repair products. Some tanks may be made of ABS plastic, which can be repaired using certain epoxies or ABS slurries. Additionally, it is crucial to ensure that any repair materials used are safe for potable water if the tank is intended for drinking water storage. Consulting with professionals or experienced individuals in RV forums can provide valuable insights into the most effective and safe repair methods for cracked seams on black tanks.
