Chimney Shield Water Repellent
For use on vertical surfaces. Our Chimney Shield system guarantees a decade of protection to prevent spalling, freeze/thaw damage and deterioration of masonry surfaces. One application forms a barrier against water, yet it allows the water vapor to escape. Non-flammable, transparent, water-based formulation works on most masonry surfaces. Apply with a low pressure sprayer to either damp or dry surfaces after proper cleaning with Masonry Cleaner.
