Description
SDI Repel 75 is a high-performance, water-based siloxane/silane penetrating water repellent and impregnating agent designed to protect porous masonry and concrete surfaces. With 7.5% active solids, this clear, invisible treatment deeply penetrates substrates like concrete, brick, block, unglazed tile, pavers, and fired clay, chemically bonding to provide long-lasting defense against water intrusion without forming a surface film.
This breathable formula allows moisture vapor to escape naturally while creating a powerful barrier that beads water on contact (beading typically develops within 72 hours). Ideal for both interior and exterior applications on horizontal or vertical surfaces.
Key advantages include low VOC content (under 0 g/L), solvent-free composition for safe use in occupied areas, Easy to apply via brush, roller, or low-pressure sprayer on clean, dry surfaces.
Product Highlights:
- Deep penetration for superior, long-term water repellency
- Maintains natural appearance—no gloss, color change, or slickness
- Breathable—prevents trapped moisture issues
- Low-odor, eco-friendly water-based formula
- Coverage: Approximately 150–300 sq ft per gallon on concrete
