We have a deck built with Correct Deck and sorry that we did. We have had a mold issue that will not go away! We have contacted the company, tried their suggestions and still have the same mold to deal with. This is not by far low maintenance decking. The dark spots of mold lighten up with powerwashing but now the deck is faded and what is left are all these brown spots. It looks terrible. They suggest using Armor All E-Z Deck Wash which contains Sodium Hypochlorite- a strong oxidizing agent. Under the Material Safety Data Sheet for Correct Deck, it states to AVOID strong oxidizing agents! So they are suggesting that we use something that the actual product says to AVOID using! I am sure that over time this will breakdown the composite not alone lighten it up alot. We removed a wood deck and replaced it with this product and it is requiring more care. If there is anyone interested in a combined effort to pursue this, I am definately interested. I will not give up on this!
