These pictures were taken inside the parking facility at Munich Airport where they wash Rental Cars, and the humidity was causing very bad mold and mildew. The German application team coated the total concrete and metal structure with SUPERTHERM ® and overcoated with ENAMOGRIP ® solvent. This was two years ago, and it looks the same today as it did when coated. Absolutely no mold and mildew has appeared on the concrete or metal beams since they were coated.
