Polar Felt Seal Waterproofing Roof Paint is designed for homeowners and DIY enthusiasts looking to extend the life of their garden sheds, garages, and flat or pitched felt roofing systems. This high-performance sealant provides an immediate, durable, and weather-resistant barrier against water ingress, helping to patch cracks and prevent further deterioration of weathered felt. While it offers excellent protective capabilities, users should note that optimal performance depends on thorough surface preparation to ensure proper adhesion to the existing substrate.

This product is specifically formulated for felt roofs and may not provide a reliable bond on metal, slate, or plastic surfaces.
In most cases, a clean, dry surface is sufficient for the paint to adhere properly.
Drying times vary based on ambient temperature and humidity; however, it should be touch-dry within a few hours and fully cured within 24 hours.
The product is currently supplied in a grey finish.
Avoid applying in freezing temperatures or damp conditions, as moisture prevents the sealant from curing correctly.
Ensure the roof was cleaned of all moss, grease, and loose debris before application.
Check for large tears that may require a reinforcement patch before applying the sealant paint.
Ensure the container is kept at room temperature before use to improve consistency.
Before applying the sealant, ensure the roof surface is completely dry and free from moss, algae, loose debris, or dirt. Use a stiff brush or scraper to clean the area, as dirt prevents the paint from adhering correctly. Apply the paint only when the weather forecast remains dry for at least 24 hours to allow the sealant to cure effectively. Store the container in a cool, dry place with the lid tightly secured to prevent the product from drying out. Regularly inspect the roof annually to identify new cracks or thin spots that may require an additional coat.
