Mildew is a close cousin of mold that is distinguished by its color. Mold is generally black in color while mildew is white. Mildew is a thin fungal filament that survives on living plants and organic materials like wood and paper, causing a distinctive smell and some potential ailments. Mildew grows best in warm, moist environments, and the best way to combat mildew growth is to prevent it before it starts.

ShieldAll 1020 – Mold Guard was created using EPA registered non-toxic materials that prevent the growth and spread of mildew; and the coating was stringently tested (using ASTM D5590 standards) for mildew resistance properties in the laboratory before it was sent out into the field. To test the coating, a sample of building material (pine / gypsum board) is painted with ShieldAll 1020 – Mold Guard, and then mildew and mold spores are added directly to the sample and the petri dish. The petri dish is then kept in optimal mold and mildew growing conditions. During the laboratory testing, it was found that ShieldAll 1020 – Mold Guard entirely prevented the growth of mold and mildew on its protected surface. These tests make ShieldAll 1020 – Mold Guard one of the best solutions for mold and mildew prevention in construction.
