Description
ChimneySaver Advanced Water Repellent is engineered to protect masonry chimneys from water damage and harmful waterborne chemicals. Its innovative polysiloxane formula delivers superior performance, rivaling that of solvent-based products. This advanced water repellent penetrates deeply into the masonry, even through previously applied water or solvent-based treatments, providing unmatched, long-lasting protection.
Unlike surface coatings, ChimneySaver Advanced bonds directly with the substrate, creating a durable barrier against water penetration—even at hairline cracks. This 100% vapor-permeable solution allows water vapor from combustion to escape, preventing trapped moisture and potential damage. Once applied, it becomes water-repellent within 4-6 hours of UV light and atmospheric exposure, and its protective strength continues to increase over several weeks.
Key Benefits:
- Long-Term Protection: Shields masonry against water intrusion, efflorescence, and staining.
- 100% Vapor Permeable: Prevents trapped moisture while repelling water.
- Polysiloxane Formula: Can be applied over previous water or solvent-based repellents.
- Non-Glossy Finish: Maintains the natural look of masonry with minimal to no change in appearance.
- Freeze-Thaw & Mildew Resistant: Protects against environmental and seasonal damage.
- Eco-Friendly: Zero VOC formula is safe and compliant in all 50 states.
- Water-Based Cleanup: Easy to clean up with soap and water.
Application and Usage:
- Compatible Surfaces: Works on most vertical and horizontal above-grade masonry, including clay brick, natural stone, concrete, mortar, limestone, terra cotta, sandstone, and more.
- Coverage Rate: 90-150 sq. ft. per gallon, depending on surface porosity.
- Application Method: Use a pump sprayer for even coverage.
- Dry Time: Dries in 1-2 hours; allow 6 hours before exposure to rain.
- Temperature Range: Apply when temperatures are 45°F or higher.
Additional Information:
ChimneySaver Advanced Water Repellent integrates into the masonry, creating a permanent hydrophobic zone that repels water while allowing free movement of vapor. It does not alter the surface color or texture, although slight darkening may occur on denser surfaces. Surfaces treated with this product may be painted with high-quality oil-based paint after testing for compatibility.
For best results, complete all repairs and tuck-pointing three days prior to application. New masonry must cure for at least 28 days before treatment.
- Available Sizes: 5-gallon containers
- Warranty: Backed by a 10-year warranty on vertical surfaces
