Important Update! Endurance BioBarrier is now Superstratum! Same great product, new name! An updated article will arrive January 2022.

In my quest to discover mold removal products that work, I stumbled on Endurance BioBarrier. Intrigued, I spent quite a bit of time on their website, on the phone with customer service, and snooping around the internet for additional insight.
Honestly, the Endurance BioBarrier seemed a little too good to be true. It really did. I mean, how is it possible that there is a product that can prevent mold for 25 years???

But before we get to that, we have to chat about the Endurance BioBarrier Cleaner Prep because that is the actual product that removes the mold. Endurance BioBarrier stops it from growing in the first place.
Endurance BioBarrier Cleaner Prep
Endurance BioBarrier Cleaner Prep effectively removes mold from all interior and exterior surfaces. It is a powerful mold removal cleaner that is water-based, environmentally friendly, and contains zero VOCs. It is designed to remove mold, mildew, and surface contaminants with ease and minimal effort. It is low foaming and rinses clean with no residue.

Active Ingredients
The tricky part about this product is that their entire formula is propriety. So finding out what is in it is next to impossible. It does smell a little bit like a sugar cookie but their website mentions a light vanilla scent.
Pros of Endurance BioBarrier Cleaner Prep
- So very easy to use! Spray it, let it set for 15 minutes, then depending on the mold situation either wipe it up or scrub to lift the mold away.
- No odor at all
- Not greasy or filmy
- Worked better at loosening mold than some other products I have tried
- Ready to use – no dilution required
Cons of Endurance BioBarrier Cleaner Prep
- Doesn’t remove mycotoxins
Toxic or Non-Toxic
Absolutely non-toxic! Their Material Safety Data Sheet shows that they scored an “A” and there are absolutely no hazardous ingredients.
Now Let’s Take A Look At The Endurance BioBarrier Mold Prevention Spray
Endurance BioBarrier Mold Prevention Spray is a formula that applies a water-based coating wherever it is sprayed. It has been laboratory and military tested and proven to inhibit the growth of molds, mildew, and biological odors on the film of the treated surfaces. Is is darn near the perfect indoor mold and outdoor mold prevention solution for home, auto, school, marine, manufacturing and industrial environments. Effective on both wet and dry surfaces. This liquid may be applied to virtually any surface or substrate.
One application of Endurance BioBarrier Mold Prevention Spray invisibly protects through hundreds of wet-dry cycles on any indoor or outdoor surface. No product on the market has the long term ability to prevent the growth of mold that Endurance BioBarrier does.
There are several ways to control microbial growth. Antimicrobials can disrupt the food cycle and “starve” the cell. Some antimicrobials disrupt the DNA and prevent the cell from reproducing. Other antimicrobials puncture and rupture the cell walls. By using a combination of antimicrobials and not relying on a single chemistry, Endurance BioBarrier uses all ingredients that cover all three methods of mold prevention.
Endurance BioBarrier, when properly applied, will prevent mold from growing back for six months up to 25 years depending on application location. They guarantee six months in bathrooms, kitchens and flooring. A two year guarantee is provided for all walls, interior and exterior, including ceilings and roofs. And, a 25 year guarantee on crawl spaces, stud cavities, or other spaces where it is unlikely that the surface will be disturbed.

Active Ingredients
Again, the active ingredients include a proprietary blend of antimicrobial/biocides that are EPA/TSCA registered to destroy pathogens and are formulated to eliminate mold, mildew and germs within 48 hours.
How Endurance BioBarrier Works
It all comes down to the BioDoor Dual Layer Technology formula.
When applied, a high tech polymer layer microscopically binds a proprietary blend of biocides and fungicides to the surface, preventing those active ingredients from being easily rinsed away.
The polymer “biobarrier” is designed to adjust to wet versus dry conditions, opening up in wetter conditions to allow just the right amount of active ingredients to be exposed to and fight mold, mildew and germs.
By protecting and rationing the active ingredient layer, the top polymer layer extends the mold prevention effectiveness of Endurance BioBarrier well beyond all competitors.

Final Verdict On Endurance BioBarrier Cleaner Prep and Endurance BioBarrier Mold Removal Spray
Go get these products now! While I love me some EC3 Mold Solution and would likely use it in place of the Endurance BioBarrier Cleaner Prep, I do think that these products work well together since they were designed to do so.
I really like how the Cleaner Prep works and the science behind the Mold Removal Spray is solid. I am currently experimenting with the Endurance BioBarrier in my shower where even I battle a little mold now and again. I will update you on how that all turns out. I am only a couple of weeks into the experiment.
I have read hundreds of reviews of both products and there is no doubt that Endurance BioBarrier prevents mold from growing. Customer after customer have raved about how it has solved their mold problem.
Why wouldn’t you want to use a product like Endurance BioBarrier that really, truly prevents mold from growing anywhere you apply it? And it’s non-toxic to boot! Endurance BioBarrier should absolutely be a part of your mold prevention strategy!

Jennifer, thanks so much for sharing all these helpful mold tips. Your blog has been a life saver! If I could only buy one product, would you recommend the EC3 Mold Solution or the Cleaner Prep?
EC3 for sure!
I was so ready to purchase this line of products but I can’t find it anywhere! Sold out of Home Depot and Amazon 🙁
Hope it comes back soon!
Hi there! The company rebranded recently and just launched. I will be updating my post soon but this is the link to their Amazon store: https://www.amazon.com/stores/Superstratum/page/4E83467D-862D-4757-90E2-885D1A21EEA4?&linkCode=ll2&tag=moldhelp-20&linkId=168e161f7dc1cc592e7c4318f3dd07e1&language=en_US&ref_=as_li_ss_tl Their products are EVEN BETTER now!
I don’t have visible mold on my tile floor, but suspect it might be there.
So for mopping would you suggest your home made solution or some other manufactured product on Amazon. I am already using EC3 candles.
Are you thinking that the mold might be on the subfloor under the tile? Or do you think you just have spores hiding in the grout? You can mop with my homemade floor cleaner for sure. I am glad to hear you have the candles already!
My HVAC fan and duct have mold, and I will be replacing the fan. Since appearance is not an issue, would it be appropriate to just apply Superstratum Mold and Mildew Protectant, and not the Cleaner Prep, to kill the mold and prevent future growth?
Hi Glenn! Glad you asked this question. The Protectant is just that… it prevents and protects but does not remove. You still want to clean the impacted areas with the Superstratum Mold and Mildew Remover or another suitable cleaner. Obviously if you are replacing the fan you don’t need to worry about that part.
