Wood Stabilizer

Strength begins within. Internal Wood Stabilizer is a waterborne mineral treatment that permanently fortifies wood fibers from the inside out, forming a mineral-based crystalline structure that resists moisture, decay, and insects. Ideal for decks, posts, garden boxes & structures, and fencing, IWS creates a dense, stable foundation for Timber Pro stains—enhancing adhesion and extending the lifespan of every board. Non-toxic, zero-VOC, and safe for surrounding vegetation and wildlife.
