Product Description
Protectosil CHEM-TRETE PB 350 is a clear, reactive penetrating sealer designed to provide superior water repellency and protection for exterior above-grade masonry surfaces. Ideal for use on concrete blocks, brick masonry, and natural stones, this product forms a permanent chemical bond with the substrate to prevent water intrusion, staining, and deterioration due to waterborne contaminants such as acid rain and mildew. The product maintains the natural breathability of the treated surfaces while significantly reducing maintenance needs.
Features
- Superior Water Repellency: Protects against water intrusion, alkali attack, and wind-driven rain, ensuring long-lasting durability.
- Breathable Protection: Allows natural moisture vapor transmission, preventing issues such as blushing and freeze-thaw damage.
- No Adverse Surface Appearance: Does not alter the appearance of treated surfaces, and allows them to remain cleaner longer.
