Composite Deck Sealer by DEFY Wood Stain

Great product does what it claims however the coverage stated on the information provided is a tad generous so knock off 25% when calculating overall area for your composite deck the product it’s a must

An old & somewhat degrading Trex composite deck was first cleaned with the DEFY deck cleaner. After drying to touch, the DEFY composite deck sealer was sprayed with a light coat onto the deck with a high efficiency airless sprayer. The application to about 850 sq. ft. of deck took about 30 minutes, with a second coat applied about a half hour later (deck was dry to the touch before the second application). The deck was left to dry until the next day. At the time of this rating, the effectiveness of the sealant is unknown. However, the deck looked like new with what looked like a “plastic-like” sheen on the boards. The DEFY Composite Deck Sealer, was the only product we could find for the condition of our deck. Our deck product was among the first composite materials available at the time of installation, & had started to decompose over 20 years. Given how well the deck looked after applying the sealer, we are very optimistic that the product will protect the deck material for years to come. The cost of sealing the deck pales in comparison to replacing the boards.

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.

easy to apply

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.

After looking for a proper sealer for my composite deck I found this brand in my seach of the internet. Watched some youtube videos about it and gave it a try. Got the first coat on and it went one easily. Not hard at all to use and easy to clean up after. So excited to find it! So far it has dried totally clear. Second coat tomorrow.
