I have same problem on my deck. I have 3 different Trex vintages as I expanded my deck. One area, all from same purchase is exactly the same. This was only 4 yrs old. I also have 10 yr which is okay but starting to show in areas. Other deck I installed 4 years ago but from a different lot purchase is fine.

I got warranty coverage on purchased materials only. I had to provide receipt, picture of the black stenciled numbers on the side and picture of the UPC code that is stapled to the end of the boards in question. Good thing I did the install myself and had a number of cut ends sitting in a pile in the back 40. I would think than many cannot get warranty because this info is long gone.

They also made me sign a waiver promising I will not say anything bad about Trex.

I didn't say anything bad did I?

Thanks! Think I'll be using this instead of Trex...

Ask if you have questions when the time comes. There are different variations of this harvested product and the physical property is a little different also. they run a few cents lower, so they are getting lots of attention. Ipe is still best I found. Good things is it isn't too much more then Redwood

Hey, you aren't "so damn dumb." Far from it.

I used Brazillian Redwood on my deck when I built it a number of years ago. It is very similar to Ipe and looks great when oiled properly. I treated mine every other year, the sunlight at 5000 feet just wore the Penofin off quickly.

So here's the plan - and I'm part way thru implementation....

I've just put a primer on the crumbling TREX crap to try and stabilize it - special 'elmer's glue' smelling stuff from Home Depot called RX-35. <-- gotta be good with a name like that!!

Then, am going to use the Behr Deckover product. Has some decent reviews and should provide a moisture barrier if nothing else. 2 coats, yay. Such fun.

I'll take some pix and post them up as I make progress.....1,000 sq ft of deck, used 5 gals of the RX-35 yesterday, and will start on the Deckover stuff later today.

thanks for your comments - I'm looking forward to replacing this crap once and for all but need a few more years out of it. Will probably go with ipe or redwood when its time....

Let us know how it goes. I am always interested in unique repairs, some work well, other not so much.

Keep in mind tht Red wood will gray and its really soft. Too soft IMO for decking. It sure is nice looking.
