Slate Roof Water Repellent

✅   Optimal protection against weather : This slate roof waterproofer is specially formulated to provide long-lasting protection against water infiltration and humidity. Thanks to its advanced formula, this product deeply penetrates the surface of the slate, forming an invisible barrier that prevents water from seeping in while allowing the roof to breathe. It helps preserve the integrity of the slate tiles and prevents damage from bad weather such as frost, leaks, and mold.

✅   Money-back guarantee : We are confident in the effectiveness of our slate roof waterproofer. If you are not fully satisfied after use, we offer a full refund. You can test the product risk-free and purchase with peace of mind, knowing you’ll be reimbursed if the results do not meet your expectations.

✅   Multi-purpose : This product is highly versatile and can be used not only on slate roofs but also on other materials such as concrete, cement, brick, mortar, and other porous surfaces. Its efficiency is not limited to slate tiles, making it a great choice for multipurpose protection and ensuring consistent waterproofing across your entire roof.

✅   Cost-effective : This slate roof waterproofer offers excellent coverage. On average, 1 liter of product covers between 6 and 8 m² depending on the porosity of the tiles. A 5-liter container can treat about 30 to 40 m² of roof. Its high yield allows treatment of large surfaces without frequent repurchase, making it a cost-effective and durable solution for preserving your roof.

✅   Safe to use : The slate roof waterproofer is designed to be safe. It contains no harsh chemicals and is environmentally friendly. You can apply it safely without any risk to your health or the health of others. As a precaution, we recommend using gloves and safety glasses during application, but there is no significant risk when used as directed.

✅   Easy to apply : This product is ready to use, making the process quick and easy. No dilution or preparation is required—simply spray, brush, or roll it directly onto the roof. This allows fast and effortless application, suitable for both professionals and DIYers. The application is even and leaves no visible traces, providing a clean and aesthetic finish.

✅   Durability : The slate roof waterproofer provides long-lasting protection. Once applied, it forms an invisible barrier that resists moisture and keeps your roof protected for several years. Depending on weather conditions and exposure, protection can last between 2 and 5 years. This durability helps reduce maintenance and ensures your roof stays in excellent condition.

✅   Quick drying and action : The waterproofer dries quickly and penetrates rapidly into the slate tiles. In general, surfaces dry to the touch within 1 to 2 hours, but for optimal performance, it is recommended to allow 24 hours before exposing the roof to rain or humidity. This quick drying helps you resume use of the treated surface promptly and ensures long-term waterproofing.

Usage Protocol

🔹 Surface preparation : Before applying the waterproofer, make sure the surface is clean and dry. We recommend cleaning the roof to remove dirt, moss, or debris. Use a broom, a pressure washer, or a brush to eliminate all impurities. If moss or lichen is present, a specific anti-moss treatment should be applied beforehand. Once the roof is cleaned, ensure it is completely dry before applying the product.

🔹 Product application : The slate roof waterproofer is ready to use—no need to dilute it. Use a sprayer, roller, or brush to apply it evenly on the surface. If using a sprayer, maintain a distance of about 30 cm and spray uniformly. For roller or brush application, be sure to evenly coat all areas to be treated without over-saturating the tiles. Apply light, even layers to prevent run-off.

🔹 Quantity to use : Depending on the porosity of the slate tiles, 1 liter of product generally covers between 6 and 8 m². This means one 5-liter container can treat 30 to 40 m² of surface. If the tiles are very porous or you wish to apply a second coat, adjust the quantity as needed. As a general rule, one coat is sufficient for effective protection, but a second application may be necessary in highly exposed areas.

🔹 Drying time : After application, the product dries quickly. Surfaces typically become dry to the touch in 1 to 2 hours. For full performance, allow the product to dry completely for 24 hours before exposing the roof to rain or humidity. This ensures the formation of an effective barrier that prevents water infiltration.

🔹 Reapplication : Depending on climate conditions and natural wear, reapplication may be necessary every 2 to 5 years. It is recommended to regularly inspect your roof and reapply the product if signs of wear or reduced effectiveness appear. A second application will help maintain long-lasting protection.

🔹 Maintenance : After application, maintaining your roof is easy. Clean it with soapy water and a soft broom or cloth to remove residues. Avoid using pressure washers or harsh chemical cleaners that could damage the protective coating. Gentle and regular maintenance helps preserve waterproofing performance for many years.
