I want to throw out to you, our valuable and persistent readers, three situations that I will be looking into. Then I will explain the processes I will use to find a resolution to each issue. And, finally, I hope to share our results. All the issues I am dealing with are complete anomalies. These are strange-but-true stories of flooring gone wrong in inexplicable ways. We will follow the process together; you may share your insight and experiences (and potential hypotheses), and I will blog updates as events unravel. Let’s go!
Today I’m sharing Mystsery #1: The Spreading Black Spots. Here’s the situation:
A man in a home built more than 70 years ago had his 2 ¼-inch red oak hardwood flooring that was original to the home sanded and finished. Very rapidly, what appeared to be black mold or mildew spread from the floor seams (gaps) and across the surface of the wood floor. I considered black iron oxide contamination, but such spots encapsulate once the finish is dry and do not spread. (For more on black spots, see my previous article “What Causes Mysterious Black Spots in Wood Floors”). Over several weeks and even months, the mysterious crud spread onto adjoining floors and materials: ceramic tile, sheet vinyl and then a leather sofa!
I am working with two laboratories on this bizarre floor problem. I think I know what this is … I need proof. What are your thoughts? Here are photos of the spots:
Post your thoughts in the comments, and I’ll update you on what I find out with this.
