Foster Sheer Defense Mold Resistant Clear Sealer (40-51) is a high-performance, water-based acrylic coating engineered to provide durable protection while preserving the natural look of treated surfaces. This advanced clear sealer is formulated with EPA-registered antimicrobial additives that inhibit the growth of odor-causing bacteria, mold, and mildew on the coating surface, helping maintain cleaner and healthier environments.

Designed to seal and protect water-damaged or remediation-treated surfaces, Sheer Defense creates a hard, mar-resistant finish that helps reduce dirt accumulation and surface wear. Its excellent water resistance ensures long-term performance without blushing once fully cured, making it particularly effective in moisture-prone interior environments.

The coating can be applied to a wide range of substrates, including bare wood, painted surfaces, masonry, brick, tile, grout, and metal. It goes on white when wet for easy visibility during application and dries clear, allowing the original surface appearance to remain visible. This makes it an ideal choice where aesthetics are important or where a non-pigmented finish is desired.

Sheer Defense is easy to apply using brush, roller, or airless spray equipment and typically dries within 1 to 2 hours under normal conditions. Its non-hazardous, low-emitting formulation supports use in residential, commercial, healthcare, and institutional settings.

With its combination of clarity, durability, and antimicrobial performance, Foster Sheer Defense is a dependable solution for sealing and protecting interior surfaces following remediation or preventative treatment.
