I have a 3 yesr old timber tech florizon deck. It needed to be powerwashed 4x between May to August to remove the black spots. I used Jo-Max and have since switched to corte-clean. Surface dirt and green areas clean up like new. After an intense cleaning you can still notice slight highlights of the "mold" spots. Within weeks they start darkening again. The spots appear around the pool area , which gets a good dousing of chlorine, as well as very dry locations. Surprisingly, spots haven't appeared around the immediate 2 feet closest to the house under our homes soffit. It seems that if it doesn't get hit with much rain, it doesn't have the problem!! This might have been a bad choice for a home in the northeast. It's now 4 weeks since the last cleaning and it's getting very ugly again. The deck is approx 60' by 40'. It is a time consuming , back breaking job for a low maintainance product. The installer, his supplier and a timber tech rep have been here to see the problem and are now waiting for a response. It was easier to power wash and stain my old wood deck once a year. |
