Defy Extreme Stain Review for 2024 4/5 (56)

Defy Extreme Wood and Deck Stain Review

We find the Defy Extreme Wood Stain to be one of the best-performing water-based deck stains on the market. The zinc oxide nano-particles do double duty in preventing UV fading and preventing mold or mildew growth. The Defy Extreme penetrates into the wood grain extremely well for a water-based stain, resulting in a non-filming coating that is not prone to peeling or wear from traffic. We personally use the Defy Extreme on about 50+ deck restorations every year in the Midwest and is one of our go-to brands.


Defy Extreme Stain Review

Defy Extreme Deck Stain RatingDefy Extreme Stain was introduced in 2008 as the newest member of the Defy Stain family. Defy Extreme Deck Stain is a penetrating water-based stain that does not film on the wood. Defy Extreme contains synthetic epoxy resins that “harden” the wood pores below the surface.

Utilizing nano-technology, Defy Extreme is one of the best stains on the market when it comes to preventing UV graying.

*Note: Defy Extreme Wood Stain is an improved version of the Defy Epoxy Fortified Wood Stain. Containing the same ingredients but with the added UV protection of the zinc oxide nanoparticles.

Defy Extreme Deck Stain Ratings (1-10)

Appearance After Initial Stain Application: 8.5

– Defy Extreme Stain had a rich look to the wood. Natural grain was highlighted evenly throughout. The Defy Extreme did not mask the grain like other water-based wood stains. The penetration of the stain into the wood was excellent. The Cedartone color was slightly on the “orange” side but acceptable for a cedar deck stain color.

Preventing UV Graying at 2 Year Mark: 9

– One of the best in the industry. Testing over a 2 year period showed little to no color fade. The zinc oxide nanoparticles seemed to help drastically with the UltraViolet radiation that turns the wood gray.

Wear/Tear and Peeling: 8

– Better than average wear and tear. High traffic areas show some wearing but overall tested
extremely well. No noticeable peeling.

Cost Per Square Foot: 7

– Defy Extreme costs about $55 per gallon. For two coats we got about 100 square feet per gallon. We used 8 gallons for the 750 square foot deck translating to a per square foot price of $.55 a foot.

Preventing Mold/Mildew/Algae: 10

– Defy Extreme Stain is a water-based stain that does not promote mold growth in the stain. A very small amount of algae was noticeable but was only in a shaded area and was on top of the stain. More of an issue with the decks’ location, not the stain itself.

Ease of Application: 7.5

– Fairly easy to apply. One issue we noticed was that it can dry very fast when in direct sunlight and on a hot day. Easy cleanup with water.

Color Shifting (darkening) after 2 Years: 9

– Stain changed very little in color after the 2 year period. No noticeable darkening.

Difficulty of Reapplication: 8.5

– No noticeable darkening, deep penetration, and little wearing make the Defy Extreme Stain an easy product to reapply when needed. Mild wood cleaning with the Defy Wood Cleaner and Defy Wood Brightener is what you would need to use to prep.

Overall Score Defy Extreme Stain at 2 Year Period: 8.47

– Defy Extreme is an excellent product and easily outperforms the majority of stains on the market. When it comes to water-based “Eco-Friendly” stains, Defy Extreme is our top choice. Defy Extreme performed in the top three of all stains tested when it comes to preventing UV graying on a horizontal surface. On vertical surfaces such as railings, the Extreme had no color change.

Texas Gulf Coast Dock Application Review.

I have a 2 1/2 year old pressure treated pine dock on the Texas gulf coast that needed a sealer preservative application. I had applied Thompson’s after initially allowing the wood to dry for a few months, but the sealer had lost its effectiveness after only 9 months or so. I researched diligently and chose Defy.

I followed the instructions strictly, using first their wood cleaner, then Brightener, then a week later applying the stain. (I had already pressure washed the deck boards before beginning.)

I am highly impressed by the products thus far. The cleaner was very effective and easy to use. The Brightener was a really easy step that I was curious about, but I did it and I’m glad I did. The Brightener makes a huge difference in opening up the wood pores to receive the stain/sealer.

I then applied the Extreme stain/sealer in Natural Pine color. I sprayed it on with a deck pressure tank sprayer followed immediately by brushing in with a car wash type brush (Unger) and followed with a second wet on wet coat, same steps, within 15 minutes or so, again following the instructions as strictly as I could. I was careful not to over-apply. (The deck is about 500 square feet, but I only used about 3 1/2 gallons.)

I am super happy with the whole process and appearance on completion. It looks fantastic. Really first rate. Let’s see how the next two years of wear and tear go.

Bill in Rockport.

Hey Bill, how did this hold up for you? I’m in Florida and looking to do the same on large deck – blazing sun, humidity and subsequent mildew here is probably similar to Texas conditions. I love the natural pine color but have been wondering if I should consider going darker for the additional UV protection. Thanks! 🙂

I live in western ny. No matter how hard I tried (and tried, trust me) I was only able to get off 80-85 of my old cabot stain off of my pressure treated deck. Would Defy Extreme still be a good choice for me?

The sun facing side of my cedar shingled sided So. Cal house near the ocean gets hammered by the elements. I've used both Cuprinol and Deckscapes water based stains, can I switch to an oil base, or stay with a water based Defy Extreme?

The sun facing side of my cedar shingled So. Cal house near the ocean gets hammered by the elements. I've used both Cuprinol and Deckscapes water based stains, both only lasting 18 months before drying and fading. Would you recommend the Defy Epoxy Extreme for better results?

We have 6 yr old PTW deck that had water based semi transparent stain (brand or color unknown). Vertical surfaces have held up fairly well. Deck surface is very worn and there is quite a bit of green algae on all surfaces. How do we re-stain and get uniform color? Do we have to strip all the vertical surfaces? Would prefer to use water based stain. Can we just apply Defy stain over entire surface without stripping the railings? We can live with some uneven color, but will that be too much?
Also, We've tried Wolman DeckBrite to clean it, but still have some green algae that didn't come off. Thanks.

I installed cedar shingles on my cabin last fall. It is now ready to be stained. I was thinking to use Defy, but I am hesitating due to the dripping and difficulty to apply on vertical surfaces.
Would you recommend Defy in my situation?

I have a PTW deck that had silkens on for 4 years with good results. Deck gets 20% sun. This year after a bad winter The deck needs resealing. I will strip all the old finish off and want to apply Defy extreme but I want a darker color like walnut. Can I mix a watco walnut stain in the Defy extreme to make it darker? I did that with previous stains and got good results.

We applied this product as recommended in sept 2012. Looked great for the first month, but then had ~30% of the deck peel over winter (by Feb 2013). Not sure what has gone wrong as we followed all instructions re preparation.

I purchased the cedar (5/4X6) in June, it sat in the drive for a month before I installed it. After installation it sat for another month un-prepped (it was dry during this period) before I used the defy wood cleaner to clean the wood. I then waited 2 d to ensure the wood had dried from the cleaning and applied the stain. I was originally going to go with a behr stain but after reading the reviews on this site opted for the defy. I used the behr product as trim on the margins of the deck and on the edges of planters and seating-it came through the winter unscathed which makes me think there isn't a problem with the wood.

Hmmm, interesting: this is from their product sheet: "New cedar should be cleaned and stained as
quickly as possible to avoid damage from the sun and rain." https://www.defyextremestain.com/pdf/extreme-wood-
did I miss something here?

Not sure if it helps, but some sections happened to be covered through the winter and they look great, it was only where the defy stained sections were open to the elements that I had a problem.

This is an awesome website with a ton of info on the different stains available. I am still torn between going with a water based stain vs. an oil base. I am nearly finished sanding a 10+ (who knows) year old PT deck down to the fresh looking wood. There is also a cedar arbor I am power washing that sits above a pressed concrete patio. I am concerned about using an oil based product on the arbor because of the possibility that it might get onto the concrete (even with a tarp in place). I am also concerned that a water based stain will be difficult to reapply in the future. The other factor is the age of the deck. It is has been neglected for a few years and required deep sanding. The wood seems dry and leads me to think that an oil based product will rejuvenate the wood. Based on these things do you recommend oil or water based? Thanks for your help!

Ok will do. I have one more question. I used 120 grit sandpaper to finish off an area of the deck to reduce (hopefully eliminate) the splintering of the wood. I read somewhere that using 120 will make the wood so smooth that it will reduce the ability of the wood to absorb a stain. Do I need to go over this area with a courser grit to open up the wood? After putting so much time into the prep I want to make sure the staining goes smoothly. I need a two year break after this! Thanks!

I live in Green Mts. Vermont. Deck has Northern exposure made from western red cedar. Grass in this area turns to moss. First product I tried 10 years ago was Wood Iron. Mold started growing after 2 weeks. Since then I save sanded everything off twice. Permacheck product I now use looks awful, but no mold. I am considering TWP 100 possibly w/ Defy extreme. I also considering Cabot Australian Timber Oil w/ Defy Extreme Clear over the top. Comments/ recommendations appreciated.

Thanks for providing such a helpful web site. I live in hot and humid Baton Rouge, Louisiana and have a 10+year-old deck in full-sun. It hasn't been maintained for about 4 years, and has turned completely gray with a few patches of black mold and water stains, and a few places where the wood is separating. I'm looking to clean and seal it with non-toxic products (it's next to an herb garden). Once I've got it cleaned, I'd like to keep the look of the natural wood, as opposed to an opaque stain.

In reviewing potential products, my inclination is to go with the Restore-A-Deck Cleaner & Brightener and Defy Extreme Stain in Natural Pine. Two questions: (1) Are these products the best to use, and if not, what are? (2) What is the best way to address the separating/ splintering areas, and if replacing the wood/sanding is involved, how would that affect applying the products? Thanks!

I am so confused with deck stains. Hopefully you can help me. I am located in southeastern Pennsylvania. I have a north west facing cedar deck that is about two years old. We originally treated the deck with the water based cwf semi-transparent. I have been very unsatisfied with the durability of this product. All the high traffic areas are almost completely worn away. There is a ton of algae growing on the steps. Part of the deck including the steps gets virtually no sun as it is shaded by the house. The rest of the deck gets a good amount of full sun in the summer. To complicate matters further a tree fell on the deck during hurricane sandy and half of it was destroyed. So now I have a deck that is half new and half old. What recommendations do you have for me? I have been considering the TWP 1500 but would really like to stay away from oil based. I am also considering the defy extreme. Help!

I just finished building a pergola and railing with tigerwood and rough sawn cedar. I live in the San Francisco area and am trying to decide on the best stain to use. I was originally thinking of using Defy Hardwood on both, but the product sheet recommends Defy Epoxy Fortified for rough sawn lumber. Since Defy Extreme is an upgraded version of this should I use Defy Extreme on the cedar and Defy Hardwood on the tigerwood? How should the new wood be prepped for staining? Should I stain now or wait? If waiting is recommended, how long? Also, which shade of stain will yield the closest end result to the original wood color?

Hello,
We live in Chicago and are just finishing new construction with cedar trim and siding. If the weather stays above 50 should we stain now or wait til spring. I am concerned that the winter will weather the wood more than we would like. I could stain most of it inside before it goes up. However, I read that with new wood one should wait several months. Can you clarify what is best. What would you suggest Defy or TWP1500? Thanks

Your website is a great resource. One week ago I just had put up 150 linear feet of 6-foot tall new cedar fence with PT posts. We live in Massachusetts so we get humid summers and snowy winters. Fence is in shaded area, under trees, so gets filtered light and may get some mildew. I want to protect wood from water damage , but let color gray naturally. I don't mind superficial mildew that can be sprayed off. 80 feet of fence sits next to property line and, even though we are friendly with neighbor, don't want to be trampling through their yard several times a year to reapply sealer. So I am looking for a clear coat sealer that will last a year or so and is easy to reapply (hopefully just recoat), without stripping down or bleaching the previous coat. I read good things about Defy Extreme Clear here, but product sounds finicky to apply and tough to remove necessary. I also what I read about Armstrong Clark product, but, again, how hard is it to maintain. Also, how urgent is it to seal the fence at this time: We are entering wetter season and expect a week of rain from hurricane Sandy, so fence may be exposed to weather for three weeks.

I'm planning to install western red cedar T&G siding on an addition in Toronto, Canada. I'm planning to stain both sides of the siding indoors before installation next spring. Should I buy the siding now and let it rest in the house over the winter before staining with Defy Extreme or should I buy the siding in the spring and stain with Cabot Timber Oil and then stain it again before the winter with Defy Extreme for durability?

I really appreciate this site! I am in the foothills of the Sierra Nevada in California. We get very hot dry summers. Almost no rain for half the year, lots of full sun. Then the rest of the year it rains a lot, and for about two months it can rain half the days or more. Occasionally it might rain almost every day for weeks. We had a cedar deck, but at this point we are thinking of putting down outdoor carpeting, so the issue is the railing–also cedar. There are 4 X 4 vertical posts, with 2 X 4 supports and a 2 X 6 rail. We are thinking about refurbishing the posts and replacing all the rails, which have a lot of splitting, deterioration and rough wood, as we have not put anything on the wood in 10 years. Also, the posts are MUCH harder to replace, but they are mostly in good shape, if cleaned. With all this mix of old and new wood, and extreme climate differences, I am wondering what to do after reading ALL the comments on this page, and some on other pages. Here are the choices I see:

*Sanding down the 4 X 4 posts, vs. cleaning, bleaching and/or pressure washing them (maybe followed by very light sanding?) before staining.
*Despite the posts being cedar, we have considered switching to redwood for the new rails, for what might be a nicer look and hold up better — so, cedar vs. redwood rail mixed with cedar posts?
*Use Armstrong Clark, TWP 1500 or Defy Extreme, or ?? and when to apply? Actually, it looks to me like TWP 1500 might be the best choice, but I guess I could not apply that right away on new wood. If so, would I wait till spring, and then clean the wood first before applying?
*I have not even considered using anything but transparent, but maybe I would be better off using a color stain to get a nicer look, particularly with the combination of woods. The top board of the railing takes a beating with the sun. We thought that redwood would hold up better than cedar there.

Sorry for so much complexity–can you help?

Thanks, Michael

Hi, and thanks so much for your response to my questions. I've been pondering your #3 answer, that Armstrong Clark is made in my area. I'm not sure what you meant by that. On their web site, it says they are in Michigan, and I could not locate any dealers in California on their web site. Is there any way I can find a dealer here in CA? I probably only need one gallon, so better if I could get in somewhere in the Sacramento area.

Michael

Sorry about that. I did locate the manufacturer just this morning, and phoned them. They have a dealer within 1/2 hour from me in Auburn, CA. By the way, we sanded all the posts considerably, and took them down to new-looking wood. All the verticals members of the railing will be cedar, and the horizontals, top and bottom and cap, will be beautiful "B" grade redwood with a mix of red and white wood. I will probably use Armstrong Clark semi-transparent Sequoia Redwood stain.

Live in Southeastern Michigan and have not found that TWP lasts much more than 1-1.5 yrs in terms of fading and maintaining water beading. Have used a Sikkens product in Northwestern Michigan on Lake Michigan waterfront deck and it still is working out well at 3 yrs. Would you recommend Defy Extreme over TWP in SE Michigan, or should I consider a Sikkens product?

Could not get TWP here in Canada so I went with this product instead… ease of application 3/10. Just like painting with water: drippy, runny, ultra fast drying. Did a poor job on my cedar deck I just spent countless hours sanding. Blotchy look, I hate it.

Thank you for taking the time to make this site. I have a brand new rooftop deck made from Western Red Cedar on top of a 4 story building – it's going to see sun basically all the time. It's very hot during the summer and will get cold in the winter. It also has railings which need to be treated. We love the look of the cedar by itself, but are thinking it will fade very quickly if we do any type of clear stain. I'm wondering if you would go with the TWP 1500 for protection vs. the Defy Extreme because of the ease of application or if you have other suggestions? It's very sunny and we are worried that the wet on wet application would be near impossible w/a fast drying stain.

We have a redwood deck that was treated with OneTimeWood 2 years ago, and we'd like to switch to a different product. We're not happy with how the OneTimeWood finish has lasted, it's mostly worn off already. We live in a cool, rainy coastal climate in northern California. Would Defy be a good option for this deck? Do we have to remove the OneTimeWood before switching to another brand? I so, how do we remove it?

Can you provide comments on Wolmans deck stain? How does it compare/rate to Defy? I found Wolmans to be very easy to apply, great color consistency, very easy clean up and looks beautiful. I have a 2×6 redwood deck. problem is that it fades very quickly. It last 2years at best. I live in Colorado and maybe that is the best I can hope foe? Furthermore, it is very cost effective.

I have a new PTW deck and I have been reviewing your site. Very interesting reading BTW. I am considering using the Defy Extreme over the TWP 1500 primarily because it is water based. Unfortunately, Defy only has 3 colors, but of primary concern to me is resistance to splitting. Deck will get morning sun -East facing. Either of these better in that regard? Also, on the Defy website it says that the hardwood product should be used over the Extreme. Any thoughts on that?
