Siloxane PD Pre-Diluted Water Repellent - Bulk
Siloxane PD Pre-Diluted Water Repellent — Ready-to-Use Protection for Concrete & Masonry Sure Klean® Weather Seal Siloxane PD is a ready-to-use, water-based silane/siloxane water repellent formulated for concrete, masonry, and stucco surfaces. Designed for both field and in-plant application, it delivers long-lasting protection against water intrusion without requiring on-site dilution. This product is ideal for contractors and trades professionals seeking a straightforward, low-odor solution for protecting vertical and horizontal masonry surfaces. Unlike concentrate-based repellents that require careful on-site mixing, Siloxane PD arrives pre-diluted and ready to apply, reducing preparation time and the risk of incorrect dilution ratios. Its alkaline-stable, water-based silane/siloxane chemistry penetrates deeply into substrate pores for durable, long-lasting repellency while preserving the surface's natural breathability. Technical Specifications Specification Details Form Ready-to-use (pre-diluted) Base Water-based silane/siloxane Suitable Surfaces Concrete, masonry, stucco Odor Low odor pH Stability Alkaline stable Breathability Will not impair natural breathing characteristics of treated surfaces Size 1 Gallon Application Method Field and in-plant application Service Life Up to 10 years Surface Orientation Vertical or horizontal surfaces Key Features & Benefits Ready-to-Use Formula Siloxane PD arrives pre-diluted, eliminating the need for on-site mixing. This saves preparation time and ensures consistent application strength across every job. Deep Penetrating Protection The silane/siloxane chemistry penetrates deeply into substrate pores rather than forming a surface film. This deep penetration provides long-lasting water repellency that resists cracking, spalling, staining, and other damage related to water intrusion. Up to 10-Year Service Life With a service life of up to 10 years, Siloxane PD reduces the frequency of reapplication. For contractors managing maintenance schedules on large masonry structures, this long-term durability represents significant cost savings over time. Breathable Treatment Siloxane PD does not impair the natural breathing characteristics of treated surfaces. Moisture vapor can still escape from within the substrate, preventing the trapped moisture problems that can occur with film-forming sealers. Low Odor, Water-Based Chemistry The water-based, low-odor formulation makes Siloxane PD suitable for occupied or enclosed environments where solvent-based products may not be practical. Its alkaline stability ensures compatibility with the high-pH environments common in fresh or cured concrete and masonry. Versatile Application Siloxane PD is suitable for both vertical and horizontal surfaces, and supports field or in-plant application. This flexibility makes it a practical choice across a wide range of project types and conditions. Common Applications Concrete Surfaces Apply to poured or precast concrete to protect against water intrusion, cracking, and spalling caused by freeze-thaw cycles and moisture absorption. Masonry Walls Treat brick, block, or stone masonry walls to resist staining and water damage while preserving the surface's natural appearance and breathability. Stucco Exteriors Siloxane PD is formulated for use on stucco surfaces, providing water repellency without trapping moisture behind the coating. In-Plant Precast Treatment The ready-to-use formula supports in-plant application on precast concrete elements before installation, allowing water repellent treatment to be incorporated into the production workflow. Horizontal Flatwork Suitable for horizontal concrete applications such as walkways, plazas, and flatwork where water pooling and intrusion are ongoing maintenance concerns.

A: No. Siloxane PD is a pre-diluted, ready-to-use product. It can be applied directly without any on-site mixing or dilution. Q: Will Siloxane PD change the appearance of treated surfaces? A: The source material does not specify a stated appearance effect, but the product is formulated to protect masonry and concrete while preserving their natural breathing characteristics, indicating a non-film-forming treatment consistent with penetrating water repellents. Q: How long does Siloxane PD protection last? A: Siloxane PD is rated for up to a 10-year service life on treated surfaces. Q: Can Siloxane PD be used on horizontal surfaces? A: Yes. Siloxane PD is suitable for both vertical and horizontal surfaces. Q: Is Siloxane PD safe for use in occupied or enclosed areas? A: Siloxane PD is a low-odor, water-based formula, making it more suitable for occupied or enclosed environments compared to solvent-based alternatives.
