Ronseal Thompson's Black 10-Year High Performance Roof Seal provides durable protection in extreme conditions, forming a flexible, elastomeric membrane that resists splitting and cracking.

Its UV-resistant, breathable coating allows trapped moisture to escape while keeping external moisture out, helping extend the life of roofs made from felt, asphalt, slate, tiles, concrete, brick, corrugated metal and wood. The black seal covers up to 2m² and dries in approximately 6 hours.
