Ensure the roof surface is clean, dry, and free from dust, dirt, moss, or any loose particles. Repair any visible cracks or damages using appropriate fillers or sealants to ensure a smooth surface. Stir Roofseal Classic thoroughly before use to achieve a uniform consistency. Apply the first coat evenly using a brush, roller, or spray over the prepared surface. Allow the first coat to dry for approximately 4–6 hours, depending on weather conditions. Apply a second coat perpendicular to the first for maximum coverage and protection. Protect the freshly applied surface from rain or moisture for at least 24 hours after the second coat. Once the coating has fully cured, the roof is protected with a flexible, durable, and waterproof membrane.
