Foster® 40-50 Interior-Defense™ Mold Resistant Coating
A tough, water resistant coating for use in areas prone to mold growth. Specially formulated with select EPA-registered antimicrobial agents to provide long-term protection against odor causing bacteria, mold and mildew growth on its surface. Ideal for use in attic spaces, wall cavities, crawl spaces, floor joists or wherever mold remediation has occurred. Can be used over a variety of surfaces such as wood studs, OSB, plywood, painted surfaces, wall board, masonry, and metal. Applied at a coverage rate of 300 sq. ft. / gallon for fast drying and low odor application. Low viscosity and good body allows easy application with most airless spray equipment, brush, or roller. Water based formulation for non-hazardous application and use when applied according to instructions. Can be used for industrial, commercial, residential, hospital and school applications. Meets requirements for LEED IEQ 4.2 Low-Emitting Materials, Paints and Coatings. VOC: 38 g/l, less water and exempt solvents
Do not store or apply below 40ºF (4ºC) or above 100ºF (38ºC). Protect from freezing until dry. Surface must be clean, dry and free of wax, grease, oil, dirt, and other surface contaminants before the product is applied. Water based products may corrode carbon steel spray equipment.
