Eco Advance Siloxane Concrete & Masonry Waterproofer - Concentrate

In this review the Eco Advance Siloxane Concrete & Masonry Waterproofer Concentrate is evaluated for homeowners and small contractors who need a breathable, eco-friendly sealer for concrete, brick, stucco and stone. The bottom line: it is a versatile, plant- and pet-safe concentrate that makes up to 5 gallons of siloxane waterproofer and excels at providing a clear, vapor-permeable barrier. The single biggest reason to consider it is its combination of commercial-grade protection and a water-based, non-toxic formula that lets substrates continue to breathe while shedding liquid water.

Key Features

• Concentrate formula: Creates 5 gallons of ready-to-use siloxane waterproofer, making it cost-effective for larger jobs or several small repairs.
• Broad substrate compatibility: Works on concrete, brick, stucco, stone, EIFS and pavers so one product covers most masonry surfaces around a property.
• Durable protection: Provides long-lasting defense against water damage, oil, stains and de-icing salts to extend surface life in tough weather.
• Eco-friendly and safe: Water-based, non-toxic, odorless and non-flammable, suitable for use around people, pets and plants.
• Breathable performance: Vapor permeable formulation allows substrates to cure and avoids trapping moisture that can degrade masonry.

Who It's For

This concentrate is best for homeowners, landscapers and small commercial crews who need a reliable, non-toxic sealer for driveways, patios, pool surrounds and exterior walls. It suits projects where breathability matters, such as new concrete pours or historic masonry that must continue to exchange moisture with the air.

It is less suitable for users who require a colored or film-forming coating, or those who expect absolute impermeability to water; some customers reported mixed results on complete water exclusion so heavy ponding applications may need a different approach.

Pros & Cons

Pros

• Effective, clear barrier that preserves the natural look of masonry while repelling water and common contaminants.
• Concentrated mix yields five gallons, improving value for larger areas and repeat jobs.
• Water-based and non-toxic, making it safe to use around plants, pets and people without strong odors.
• Vapor permeable formula supports substrate health by allowing moisture escape.

Cons

• Water resistance feedback is mixed; it repels water but is not a guarantee against all ponding or severe leakage situations.
• As a clear siloxane treatment, it does not provide color enhancement or a film-like finish some users prefer.
