The Brand
EternaBond is a division of Royal Adhesives & Sealants, LLC that offers roof repair solutions.
They built their entire business on the back of the MicroSealant adhesives that their EternaBond tape has, providing a permanent bond to most surfaces that you’ll find on roofs that need repairing.
If you needed convincing about the authenticity of EternaBond’s products, Royal Adhesives & Sealants, and all their acquired sub-brands and technologies were themselves bought by H.B. Fuller, EternaBond included.
When it comes to industrial adhesives and sealants, H.B. Fuller is one of the big players in the industry, so it makes sense they’d acquire EternaBond’s roof tapes that can do both.
The Product
So, what is EternaBond in regard to the product they offer? EternaBond is the registered name of a range of easy to use one-step sealant tapes manufactured for roofs and roofing accessories.
This includes the roofs of mobile vehicles like RVs if the name of this page wasn’t already an indication.
Without the use of other sealants, EternaBond products use that aforementioned MicroSealant Technology to make the tape not just waterproof, but airtight.
The tapes themselves are made with 100% solids, namely synthetic resins combined with non-curing rubber, some thermoplastics, and a primer that facilitates their interaction.
This is all bonded via a UV-stable tape backing, so long-term degradation through prolonged sun exposure isn’t a worry anymore.
As you’d expect with any tape of this caliber, they have silicone release liners that must be removed to expose the adhesive face and make the application possible.
That MicroSealant Technology is a closely guarded secret in EternaBond tapes. They work using a variety of sealants that are aligned in such a way that, when primed and applied, become so stable that light or heat can’t weaken it.
There are primers built into the synthetic polymers found in this tech.
No matter where you are, you don’t have to worry about the deterioration of your tape brought about by the environment.
This is because there are temperature precautions built into the tape itself, like bonding substrates so that the tape becomes waterproof to any liquid that would otherwise end up bypassing the tape and invading your RV.
What better way to understand EternaBond products than seeing them for yourself? Below we’ve provided some links to EternaBond tapes that are compatible with the roofs of RVs.
As you can see, we’ve also included some short, quickfire reviews for those of you that want any suggestions, so check them out if you need some tape.
Top 5 EternaBond RV Roof Tape
OUR TOP PICK
If you need a lot of EternaBond tape, check out the EternaBond RSW RoofSeal.
This is one of their most popular and best-selling products, so it’s a great option to get familiar with the EternaBond brand. RoofSeal is their workhorse tape option that’s ideal for roofs of any kind.
Though EternaBond has RV- and mobile home-specific tapes, as you can see below, there are plenty of reviews of RoofSeal from RV owners who have found this tape to be sufficient.
So, what makes the RoofSeal better than other tape options? First, you have a choice in the size of the tape you get to suit your needs.
Naturally, the more of this universal tape you get, the more you’ll pay for it.
Aside from that, it features EternaBond’s safety features like a silicone lining that stops you from accidentally sticking it to the wrong surface.
It also won’t deteriorate in sunny environments.
What sets the EternaBond RoofSeal apart is its very high elongation factor.
This means the RoofSeal, more than other brand tapes and some of the other EternaBond tapes, can contract or expand as the conditions around it change.
This means it won’t get loosened when temperatures change.
The tape can adapt to its surroundings to ensure that it remains flush against the surface it’s fixed on, which is a big deal when your tape is being used outside.
Since most EternaBond products are roof repair tapes, they don’t tend to stick well to plastics or metals.
Pros:
- RoofSeal is EternaBond’s universal roofing tape that can tackle both domestic and mobile home roof repair.
- A silicone layer reduces the likelihood that the tape gets stuck where it shouldn’t.
- The RoofSeal has a very high elongation factor, so it can expand or contract to retain its stick.
Cons:
- Since this is best for roof repair, it won’t stick very well to plastic or metal.
