We followed the manufacture's instructions religiously. We also watched their video for product application. We used Rust-Oleum deck cleaner for preparation and their special roller for application.
Fast forward to March 2014 and this stuff is peeling and cracking everywhere.
The failure mode is either peeling up in large sheets or it crumbles when you step on it.
The major problem is that in sections of the deck where it neither peels nor crumbles, its removal is all but impossible without destroying the wood decking.
The only thing I can do now is pull up the fir decking and either replace it (very expensive) or turn the decking over, put it back down and use a conventional stain (labor intensive).
Needless to say, "I am not happy".
Please do not simply believe what I say. Verify this for yourself.
