DEFY Crystal Clear Composite Deck Waterproofing Sealer, 1 Gallon

Fantastique

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

I did a fair amount of research and this DEFY stuff kept coming up as the best so I decide to try it. Lots of prep time so I wanted to put down the best. This is a 20 year old original and never sealed Gray Treks Deck. It is 12' x 30' or 360 sq. ft. The stated coverage per container of 300 sq. ft. was the minimum so I bought 2 thinking it was more than enough. I was a little concerned as I started because the deck was taking quite a bit but I had enough to do 2 coats. Pictures are as follows: 1st was deck prepared, 2nd shows there was a distinction after applying & drying, 3rd was the pad & tray I used to apply, 4th is showing a little more than 1/2 of the 2nd. jug left after 1st coat and last picture is deck after 2nd coat. I have a small amount left. There were no overlap marks. I did have to do in-between the boards with a brush which was time consuming and tiring but necessary. The rest was done with the pad and was easy. The second coat obviously much easier and the coating went a much longer way. So my planks were fairly rough or porous which is why I did a second coat and I'm pleased with how it looks. I'm giving 5 stars for ease of application and looks and will return to review its durability at a later date. 4-10-21 It's Spring 2021. Our deck is on the North side of our house and after the fall & winter there is always significant mold & mildew especially nearest the house. This year there is none so this product works. I think prep is very important so I was diligent about this because I wanted to give it the best chance to work. It's said it will last a couple years so we'll see how it looks in Spring 2022. Right now I'm thrilled I don't have to power wash it.
