Product Description
Masonry Defender 300602, Silane-siloxane Industrial Sealant, 8.02 lbs
About This Item
Protect and enhance the beauty of your exterior masonry and concrete surfaces with our All Purpose Concrete, Brick & Stone Sealer. This clear, penetrating water repellent is specially formulated to provide long-lasting protection against water damage and freeze/thaw damage. Whether you have concrete, brick, natural stone, sandstone, limestone, cultured stone, or granite surfaces, this versatile sealer is perfect for all of them. It creates a strong waterproof barrier that prevents water from penetrating the surface and causing damage. One of the key features of our sealer is its breathability.
Unlike other sealers that form a film on the surface, our sealer allows trapped moisture to escape. This prevents issues like pitting, cracking, and delaminating, ensuring the longevity of your masonry and concrete surfaces. Not only is our sealer effective, but it is also eco-friendly. It is water-based and can be easily cleaned up with soap and water.
Plus, it has a low odor, making it convenient to work with. For your peace of mind, our All Purpose Concrete, Brick & Stone Sealer comes with a 5-year warranty on vertical concrete and masonry surfaces. We stand behind the quality and durability of our product. Please note that this product contains chemicals that are known to the State of California to cause cancer and birth defects or other reproductive harm. Take necessary precautions and handle with care. Choose our All Purpose Concrete, Brick & Stone Sealer for superior waterproofing and protection.
