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 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.

DEFY Extreme, Deck Stain: 12 Months Weathering and 14 Month Update
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.
Thanks for your review.
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 put one coat of Defy on a new kdat treated lumber dock about 18 months ago. What steps would you recommend before applying the second coat and do we need to apply a second coat to the vertical post as well? Thanks!
Use a deck cleaner and then one coat of the Defy. If verticals look good, then just do the horizontals.
Have a 3 year old cedar deck(2×4) that was originally painted. Would like to stain it. Is it ok to sand it with a belt sander prior to staining? I there something else I should be doing as well? Please advise. Thanks.
You will need to fully remove the paint if you want to stain. See this for tips on removal:

I have a new deck , weathered 6 months . I’m ready to clean and brighten . It’s pine , part covered and part uncovered . What’s the main difference in choosing oil or water based ? I really want a stain that is easy to maintain and I don’t need to strip to reapply. Thanks !
See this about new wood:
https://www.deckstainhelp.com/how-long-should-you-wait-to-stain-a-new-deck/
Does not matter if oil based or water based. What does matter is the quality of the brand and if fully penetrating or not.
It’s been 18 months since our last application of Defy stain on pressure treated pine and the only wear we see is at knot holes, and we would like to reapply the same color. Only the horizontal boards need to be done. The vertical ones look great. Questions:
1. Can we prep with only Defy brightener as the container suggests or do we have to use the cleaner first?
2. Will the brightener running down the vertical boards make them have to be restrained too?
3. What would happen if we just restained without cleaner or brightener (like my husband wants)?
1. Brighteners will not prep this properly for reapplication, you need to Clean and then Brighten.
2. Probably not.
3. Skipping steps causes premature failure that you will blame the stain but actually happened due to not following directions.
can I get away with one coat or do i have to do two coats?
Depends on the age of the wood.
I used Defy for the first time on a newly constructed pressurized pine deck. I let the deck rest for six months before the first application. The paint has a consistency of water and does not yield even color. After once coat, some of the deck had barely any gray color and other sections were dark gray. The color is uneven and splotchy. I will have to paint over this with another brand of paint. I was so disappointed in the results. I have been painting my decks for thirty years and have never been this dissatisfied with a paint product. I can’t return the extra paint because I bought it in the fall and had to wait until spring to paint.
Defy is not a paint but a penetrating stain that enhances the natural grain of the wood. The final color is determined by age, wood type, and the prep of the wood. I believe your expectations were different than what the product is intended to do.
Any issues using Defy: cleaner/brightener/butternut stain on an old deck which was last stained with RAD light walnut @5 yrs ago and is now worn out and in need?
It’s either Defy Butternut or RAD Dark Walnut.
But the nano particles I need!!
I’m not stripping it….
You should strip and brighten if switching brands and or colors. Defienelty if switching brand names.
Hi, I’m a new homeowner looking to restore my deck before it gets colder here in CT. Problem is I have no info about the decks treatment until we moved in so I cant tell if it was ever sealed/ stained. I tested with the water pouring test and it seems to absorb it pretty quickly.
Thanks so much in advance. Attaching photos of different parts with varying shades to give you a clear picture.
Looks just gray and dirty so for prep, use a deck cleaner and a wood brightener. The Defy Extreme Stain would be a very good choice. Look at the Restore A Deck Stains as well. The wood is pressure-treated pine.
Really appreciate the response. Thanks so much Scott!
how much time do i need to apply all three steps cleaner brightner and stain ?
No way to answer this as it is based on your project size and your experience as well.
Hi. Im sorry. what I would like to know is the recommeded drying time between the cleaner / brightner before applying stain? Thank you
48 hours.
Hi. Can I use RAD for all my prep but use Defy stain? Thank you
Yes.
Hi, I have a 8+ year old dock on a very small lake, mostly full sun, Mid-Georgia (so plenty of humidity), pressure treated. It’s in pretty good shape and has been maintained. I want semi-transparent. natural cedar tone.
Also have a deck that has a darker stain, also semi transparent. similar condition, but has some peeling.
I’m surprised at the difference in coverage between those recommended on the site and the Behr’s etc.
Thank you for any suggestions and thanks for the thoughtful website.
You have to remove the current stain first. Post pics for prep help.
Nice site. I’m building a new Japanese “roofed”, rough-out, cedar fence right beside Puget Sound…the rain seldom lets up but when it does, we have glorious periods of heavy mist. Cedar probably will never achieve a low moisture content (We’re drying it in the basement APT).
We need a stain meeting the following criteria, 1st) Prevention of graying, 2nd) Grain Enhancement, 3rd) Prevention of mold/mildew, and 4th) Durability.
Q. Recommendations, Thoughts?
Q. Should I use an oil-based product?
Q. Will Defy Extreme Wood and Deck Stain “Natural Tone” hold up?
Cordially,
Use Restore A Deck Stains in a semi-transparent color. It will give the best option for mildew prevention, and graying protection, and can be applied to damp wood.
