Water Repellents

All You Need To Know

frequently asked questions

Water repellents are products designed to protect concrete and masonry surfaces from moisture, salts, corrosion, spalling, and deterioration. They create a barrier that prevents water and other liquid contaminants from penetrating the surface.

Using water repellents on concrete and masonry surfaces is essential for long-term durability and protection. They help prevent damage caused by moisture, such as cracking, efflorescence, and freeze-thaw cycles. Water repellents also resist oil, food stains, and other liquid contaminants, making surfaces easier to clean and maintain.

Water repellents can be used on a variety of interior and exterior above-grade concrete and masonry surfaces. This includes decks, pavements, parking structures, ramps, bridges, marine platforms, and more. They are suitable for both horizontal and vertical surfaces.

Water repellents work by penetrating the surface and bonding directly with the substrate. They create a breathable barrier that allows moisture vapor to escape while preventing liquid water from entering. This helps to maintain the structural integrity of the concrete or masonry.

Yes, many water repellents are formulated to be low VOC (volatile organic compound) and environmentally friendly. They comply with stringent VOC regulations while still providing excellent protection and durability.

The application process may vary depending on the specific product. Generally, water repellents are applied using a sprayer, roller, or brush. It is important to follow the manufacturer’s instructions for proper application and ensure the surface is clean and dry before applying.



The longevity of water repellents can vary depending on factors such as the product used, surface conditions, and environmental factors. However, most high-quality water repellents provide long-lasting protection for several years.

Yes, water repellents can be applied to existing concrete and masonry surfaces. However, it is important to ensure that the surface is clean and free from any previous coatings or sealers that may interfere with the penetration and bonding of the water repellent.

Water repellents are designed to be clear and penetrate the surface without altering its appearance. They do not leave a visible film or coating, allowing the natural beauty of the concrete or masonry to shine through.

Temperature and weather conditions can significantly impact the application and performance of water repellents. Ideally, they should be applied in dry conditions with moderate temperatures. Extremely hot or cold temperatures, as well as rain or high humidity, can affect the absorption and effectiveness of the product.
