Had a new XLM deck installed - very expensive - and it is turning white in some areas. I just called Timber Tech and they will get back to me - but I am very upset. I read the post about ironing the deck which is absolutely absurd. I spent thousands and thousands for a maintenance free deck and now it needs to be ironed????? I hope XLM stands behind their product and does whatever needs to be done. The old deck I had taken out looked better than this! Guess I will have to wait and see. Sorry I picked this one!
