PolyWhey® Exterior Penetrating Wood Stain

PolyWhey® Exterior Penetrating Wood Stain is a professional-grade water-based exterior wood stain designed to protect decks, siding, fences, docks, outdoor furniture, and pressure-treated wood while preserving a more natural wood appearance.

Built with patented PolyWhey® technology, this penetrating stain delivers durable moisture and UV protection with low VOCs, neutral odor, soap-and-water cleanup, and fast dry times compared to many traditional exterior oil-based stains.

WHY USE A PENETRATING STAIN? 

Unlike film-forming exterior coatings that can peel or crack over time, penetrating stains absorb into the wood to help protect against moisture and weathering while maintaining a more natural appearance. This makes maintenance easier and helps reduce peeling issues commonly associated with surface-build coatings.
