## Description

DEFY Extreme Composite Deck Sealer – Crystal Clear Waterproof Sealant for Wood & Composite Surfaces with Zinc Nano-Technology, Protects Against Water & UV Damage – 1 Gallon: desertcart.com: Tools & Home Improvement

Review: enhances the color and quality of composite deck. - It beautifully enhanced the faded color of my old composite deck to a rich and newer look as well as provided a good seal . Applies easily.
Review: Learn from my mistake - I have a cheap composite deck. It has oxidized very poorly. Our house is only four years old but we have considered replacing it. I thought I would try this. At first I was applying this thinly brushing the liquid in. I was noticing it would dry fast and look basically the same. Then I started brushing where I would leave a good amount of the purplish liquid visible- making sure it got into the groves of the decking. This also allowed me to visually see if I was missing some spots. It looks great now, cant speak to longevity I'll update my review in a few months. If I have to do it every year its worth it, didn't take long and its worth the 50 bucks in product.

## Questions & Answers

**Q: will this work on Trex decking?**
A: This works very well on Trex decking.

**Q: I have eon decking which can't have any petroleum based products.  what exactly is in this product and will it harm my eon decking?**
A: I don't know about your decking product, but we used this cleaner on our "TREX" deck, and it worked great.   We power washed the deck before applying the cleaner, and it dried looking practically brand new.

**Q: Is this product water based?**
A: I haven't put it down yet. I'm not sure if it's water based or not. I'm ordering a second gallon before I start as I won't have enough to finish. I will post what I find once I've had an opportunity to use it.

**Q: Will this work on all composite decking**
A: I only know that it worked on my 14-year old Trex decking.

### ⭐⭐⭐⭐⭐ Revitalizes composite decking. Super easy to use.
*by A***R on October 17, 2023*

Regarding the photos: Before - Tan/Brown During - Wet After - Slightly Cedar/Red (The original color) I had to rebuild and replace portions of my 15 year-old deck. I also installed new posts, sleeves, railings, and facia. Anyway, the composite decking is still in great shape, but it was faded. I was going to use a tinted sealer, but the reviews were inconsistent. I used this Defy sealer three years ago, and I was satisfied with its performance. I knew what to expect. My deck is approximately 300 square feet including the steps. After thoroughly pressure washing the decking, I used 1.5 gallons of Defy to do one coat. Doing a second coat may be a waste of time, because in my experience, the product repels itself when it fully dries. Lay it on generously while it’s wet. You’ll know if it’s enough. I used a long handle and a 9”, 3/8” nap roller cover. You don’t really paint it on, you push on. That’s why by it’s so easy to do. Dip the roller in the tray like you do when you paint. Make a puddle of sealer and push it onto the decking (a 9” roller spans across the width of 1.5 planks on my deck). I pushed the sealer the of the length planks until the puddle was gone, and dipped the saturated roller back in tray and repeated. Then, I back-rolled the wet areas to make sure everything was covered. FYI: I did cut in with a paint brush and a small microfiber roller. I noticed that the cut-in areas came out slightly darker than the rest of the deck. It doesn’t look bad though. It dries to touch from 30 min to a couple hours. To be safe, let it dry overnight before you put your furniture back on the deck. I believe the instructions say 12 hours. I finished the deck last week. It has rained for several days this week, and the sealer is doing its job. You’ll know it’s working, because the deck will have water beads and puddles on it after it rains.
