SurfaceShield Protectant is a professional-grade, penetrating barrier coating engineered to protect porous building materials from damage, staining, and future microbial growth caused by mold and mildew. Unlike traditional surface protectants that must be applied only to dry substrates, SurfaceShield can be applied to materials with moisture contents between 11 % and 30 %, making it especially useful for post-remediation environments and new construction sites where general moisture may still be present.

This innovative coating creates a breathable barrier that blocks mold-supporting nutrients from migrating to the surface while still allowing water vapor to evaporate through the material — a key feature that helps maintain surface integrity without trapping moisture beneath the coating. The addition of an EPA-registered preservative provides ongoing inhibition of mold and mildew growth on the dry surface coating, offering added protection and peace of mind.

SurfaceShield dries clear so it won’t alter the appearance of the treated surface, and its water-thin, low-VOC formula makes application efficient and cost-effective. It can be applied using common tools such as airless sprayers, brushes, or rollers, facilitating ease of use for contractors and facilities personnel. This coating is ideal for a wide range of porous substrates including wood, paper, drywall, and more — delivering an extra layer of defense against future water damage and mold-related staining.
