DYNA PW-1 Penetrating Sealant is a ready-to-use, water-based silane / siloxane water repellent for concrete, natural and dimensional stone, masonry and stucco surfaces. PW-1 permits the surface being treated to breathe. It helps prevent masonry from cracking, spalling, staining and other damage related to water intrusion. It has low odor, is alkaline stable and is ready to use. Use on horizontal surfaces such as driveways, sidewalks, tile, brick, sandstone and pavers. Provides excellent protection for retaining walls, bridge pilings and other vertical areas exposed to de-icing salts.

• Penetrates deeply for long-lasting protection on vertical or horizontal surfaces
• Treated surfaces “breathe” – moisture will dissipate
• Water-based formula minimizes explosion and fire hazards compared to solvent-based water repellents
• Low odor for safer application in occupied buildings
• Alkaline stable – suitable for new “green” concrete, 14–28 days old
• Ready-to-use. No on-site dilution required
• Chemically bonds with the substrate which produces a durable hydrophobic treatment
• Effective protection against de-icing salts and salt air
• Easy soap-and-water cleanup from window glass, window frames and equipment
