My name is Rick Trottier and I am the Product Manager for Correctdeck. I would like to clear up any misconceptions about the black spots (mildew) that are appearing on all exterior surfaces, including decking surfaces.
If you are looking for information about Mold and mildew, just use any search engine on the web and type in the word "mold" and over 4,100,000 articles will pop up and the main discription about mold and mildew is consistent in just about all of them: "MOLD is everywhere" quotes the New York City Dept. of Health. How does it grow? All molds need water to grow, a food source(pollen,pollution etc) and temp (40f-100f).The black spots on Correctdeck are mildew and are not caused by Oak Fiber that was manufactured into our product.MOLD can not survive over 130 +/- degrees F. Correctdeck is manufactured at temps over 500 degrees and our sawdust is dried to below 1% moisture content. Mold is a major problem around the country today, closing schools and public buildings around the world.We have gone to great lengths researching this natural problem and have many ways of cleaning and preventing this problem (www.correctdeck.com/cleaning and care.)Correctdeck will resist the mildew as lumber will not because molds/mildew can not store carbohydrates, so they keep eating (wood rot). GREMLINS, the movie in the 80s(my kids and I rented) is just about how mold works. Constant moisture and CFU (colony forming units) will occure and then start spreading. I have Correctdeck on my home(love it) for 3 years now and with my kids and their friends running with muddy feet all over it, it has withstood the test of time.
I hope this information has helped, it is a frustrating situation in the world today and mildew is on everything (wood,roofing, siding,brick and patio stone,shower curtains,bread,drywall,etc.).
