Two years ago I replaced 1500 sq. ft. of treated southern yellow pine decking with TREX. I thought I’d died and gone to heaven when it bleached to a lovely silver grey. No more problems I thought. WRONG!
After three months blotchy spots showed up all over the deck. Finally, I was advised by TREX to use Olympic Deck cleaner to remove these “mildew” spots. Fifteen gallons of cleaner did the job. But – the spots were back in six weeks. Now I hear from my dealer that TREX has a new “darker colored” material. so mildew spots don’t show. I’m not about to tear out the decking again.
Any suggestions? Should I paint it? and, if so, what material?
