SDI Repel 120 Water Repellent – Premium Protection for Concrete & Masonry
Protect your surfaces from water damage with SDI Repel 120, a high-performance, penetrating silane/siloxane-based water repellent designed for porous substrates like concrete, brick, block, stone, pavers, and unglazed tile. This professional-grade formula (12% active ingredients) deeply penetrates and chemically bonds to the material, creating an invisible, long-lasting barrier that repels water while allowing the surface to breathe naturally—no glossy film or color change.
Key Benefits:
- Superior resistance to water intrusion, staining, efflorescence, cracking, spalling, and freeze-thaw damage
- Excellent protection against mold, mildew, and alkali attack
- Breathable formula prevents trapped moisture and maintains natural appearance
- Ideal for driveways, patios, retaining walls, facades, chimneys, and decorative concrete
- Easy application by spray, roller, or brush (wet-on-wet for best results on vertical surfaces)
- Low VOC, solvent-free for safer use indoors or occupied areas
Recommended For: Exterior/interior horizontal or vertical porous masonry where deep penetration and durable water repellency are required. Coverage varies by surface porosity (typically 100-300 sq ft per gallon—test first!).
Note: Always prepare surfaces properly (clean and dry), apply in temperatures 50–85°F, and allow full curing for maximum performance (up to 72 hours for peak repellency).
Available in 5-gallon pails—perfect for contractors, homeowners, and pros alike.
