Mildew is no match for the Medallion Series of (PMR) Proven Mildew Resistance finishes from Dryvit®. Airborne pollutants and humidity can quickly transform a building's clean exterior into a wall of unattractive, difficult to remove mildew. Now Dryvit has the answer with PMR, an EIFS breakthrough tested and proven to inhibit the growth of mildew in difficult mildew-prone environments. Another great advantage is that it also inhibits the retention of airborne dirt and pollutants, the nutrients necessary for mildew growth. A clean finish inhibits mildew growth.
