This commercial-strength, spray-applied formula delivers long-lasting protection for virtually all exterior concrete, masonry, and wood surfaces. Unlike many comparable products, Water-SIL features vapor permeability, allowing treated substrates to breathe. This helps prevent moisture from becoming trapped within the surface—reducing the risk of premature deterioration and extending the life of the material.

The entire Water-SIL product line consists of solvent-free, penetrating sealers designed to provide durable water repellency without altering the appearance of the surface. The formula is safe for use around surrounding materials—overspray will not etch glass or damage vehicle finishes, and it will not harm grass or landscape plantings.
