Introduction
As any RV enthusiast or owner will know, a watertight vehicle is essential. Beyond the obvious risk of leaks forming in the roof and window, there is also a much more insidious problem, mold. Over time, if water can enter the RV’s internal cavity, there are likely to be devastating effects.
There are a number of products on the market designed to tackle this serious issue. Seal Tite Corner Seal and Eternabond are two market frontrunners who have implemented sealing tape as an all-in-one solution to rectify this issue.
However, understanding how these two very similar products differ can be challenging. Therefore, this article has been constructed to express the differences between conscientious buyers most effectively.
RV Sealant
Sealants perform an essential job in the world of RVs. These beloved vehicles have been built with maneuverability at their core. For this to be a reality, they have had to be constructed with the intention of being as lightweight as possible to guarantee they can be maneuvered to offer vast distances reasonably easily.
The lightweight construction methods have most often been comprised of plastic paneling with foam insulation board to create a low-density material that can create a robust structure suitable for living. However, these materials are highly susceptible to water damage.
They are most often sealed with a combination of tape and sealant as an efficient means of connecting the panels, as well as offering water and weatherproofing . Over time this sealant method will become compromised over time depending on the severity of the environment that has been used.
Seal Tite Corner Seal vs Eternabond
Table Comparison
The clearest illustration of the few differences between the two sealant tapes is in the comparison table below.
| Features | Corner Seal | Eternabond |
| Price | Appro: $30 | Approx $40 |
| Width and Color | Multiple Size Options, Once Colour | Multiple sizes and color |
| Robust Design | Double Layered Tape | Strong enough to be used without additional protection |
| Exterior Use | Yes | Yes |
| Additional Covering Required | Yes | No |
As demonstrated above, there are very few differences between the two products. However, this makes their comparison all the more necessary. They are, by definition, not identical. Therefore, their comparison is even more crucial.
Price
Fundamentally, price comparison is a consideration for every purchase that is made generally. In particular, RV owners are renowned for seeking the best possible deal. This attitude is extended to purchasing minor goods such as sealing tape.
As illustrated by the table above, it is clear that generally, the Eternabond is generally more expensive than the Seal Tite Corner Seal. However, this may be due to one clear advantage; the Eternabond is designed to be a stand-alone product for repairs and installation.
Comparatively, the Seal Tite Corner Seal is designed to be used in conjunction with moldings, and it is essentially an additional protective layer that needs support.
Therefore, the additional cost can be associated with the lack of additional products required. However, the necessity will be a situation-by-situation basis bespoke to the customer’s current needs.
Size and Color Option
The Seal Tite Corner Seal is offered in a range of widths that are required for specific jobs. These requirements are essential for the product to be used properly with the additional molds that will be set on top of it.
Effectively, if the tape is too wide for the job, it will still be visible after the mold has covered it, ruining the required clean and crisp astheticd. As the tape is always designed to be covered, it is only available in one color.
Alternatively, the Eternabond has multiple widths as well as colors available for purchase. This is an essential feature considering its use. It does not require any covering, meaning it will be visible wherever it is used.
It can be colored accurately to the material it is being used in conjunction with. However, due to the growing number of color options for RV’s interiors and exteriors, it is impossible for it to keep up with every possible option.
Robust Design
Durability, insulation, and robust design is the cornerstone of an effective sealant tape. Both options have the necessary weather and waterproof membranes that actively resist nasty water infiltration ingress.
Moreover, they are both designed to last. RV owners do not want to be refitting and repairing compromised seals regularly. They should ideally last as long as possible and only require updating around once in the RVs lifetime.
The Seal Tite Corner Seal has been manufactured with a double wall system to ensure the most robust and protective barrier to foreign contaminants.
The design also aids the lifetime of the sealant table but offers a more ridged material that cannot be worn away or torn nearly as quickly. This is particularly useful for RVs who spend their life being rocked and are continually exposed to heavy vibrations for long periods.
Exterior Use/Additional Covering
Both Products have been designed to be used on the exterior and interior paneling of RVs. This is a critical specification as the interior and exterior of RV materials are closely linked, with very little space or insulation between them. Therefore, their exposure to the elements is more closely linked compared to typical home construction.
Moreover, RV owners and manufacturers spearhead functionality. RVs are compact and tightly integrated spaces. The industry has relied on elements or RVs having multiple uses. Therefore it is critical that even the sealant tape that is purchased can have both uses.
However, the Seal Title Corner Seal is inferior compared to the Eternabond due to its lack of stand-alone capabilities. It can be used on the exterior of the RV but only when it is covered by additional weatherproofed molding. Effectively, it is useless outside on its own and works with weather resistant materials rather ta comprehensiveound solution.
Conclusion
It can be said that comparing these two sealant tapes is not a fair comparison. Firstly, the Eternabond is an excellent all-in-one solution for sealing construction gaps. It has been engineered as a comprehensive solution that can adapt to a number of circumstances as well as offer temporary emergency protection.
Its adhesive is exceptional and can be set full in minutes. Exposed to extreme outdoor conditions from baking sun to the snow storm, it has been designed with resilience at its core. Often it is revered as the ideal repair solution when rooftop seals begin to fail. It performs as a superb solution for a variety of dynamic RV seal problems.
The Seal Tite Corner Seal is essentially a different product. It has been engineered for the express purpose of supporting additional weatherproof moldings. It can only be used in conjunction with other products rather than an individual solution.
Although it comes in a variety of convenient sizes and is generally cheaper, it is merely part of a more cumbersome construction element. Additionally, the Eternaboard can also be used in the Seal Tite’s place. It performs the same job, arguably better, which can be covered or left exposed.
Ultimately, these tapes may seem similar, but they are in fact, in different operational categories. Depending on the job you require, these two tapes are preferred for different situations. Be mindful to fully understand the task at hand on your beloved RV to make the best possible decision.
