Everbuild Sika Black Jack Bitumen Roof Felt Adhesive 904 Black 5Ltr 486995 | Solvent Based Roofing Felt Bonding Compound | Exterior Roof Repair Sealant | Cold Gritting Solution | Concrete Asphalt Metal Wood Surface Adhesive

Everbuild Sika Black Jack Bitumen Roof Felt Adhesive 904 Black 5 Litre is a high performance solvent based roofing adhesive designed for strong, durable and weather resistant bonding in exterior roofing applications. It is formulated to securely bond roofing felt to a wide range of construction surfaces while delivering long lasting waterproof protection. This professional grade bitumen compound is ideal for roof installation, maintenance and repair work where reliability and strength are essential.The advanced formulation provides superior bond strength, allowing roofing felt to adhere effectively to materials such as concrete, asphalt, metal, timber and existing roofing felt. This makes it a highly versatile solution for both new roofing systems and refurbishment projects. It ensures a firm and stable bond that supports the structural integrity of roofing layers in demanding outdoor environments. Everbuild Sika Black Jack 904 is engineered to deliver high strength performance while maintaining flexibility. Once applied, it forms a tough waterproof layer that adapts to temperature changes. It softens slightly in warmer conditions and hardens in cooler temperatures, allowing the bonded surfaces to expand and contract naturally without cracking or losing adhesion. This flexibility is essential for long term roof durability. The adhesive is particularly effective for sealing roofing felt laps, creating watertight joints between overlapping sections of felt. This helps prevent water penetration and protects the underlying roof structure from moisture damage. It is also suitable for bonding chippings to the final layer of felt, providing additional surface protection and improving roof durability against weather exposure and UV damage. This bitumen based roofing adhesive offers excellent resistance to environmental and chemical exposure. It is resistant to dilute acids, alkalis, water, alcohol and most salt solutions, making it suitable for harsh outdoor conditions. This ensures consistent performance even in areas exposed to heavy rainfall, temperature fluctuations and chemical contaminants. Application is simple and practical. The product can be applied using a brush or spreader directly onto clean prepared surfaces. It spreads evenly, allowing controlled application across large or targeted areas. Once applied, it develops a strong adhesive bond that securely holds roofing materials in place while maintaining long term flexibility and waterproof performance. Everbuild Sika Black Jack 904 is compatible with a wide range of roofing surfaces including concrete bases, asphalt roofing systems, metal sheets, timber structures and existing felt layers. This broad compatibility makes it a reliable choice for both professional roofing contractors and DIY users working on different types of roofing structures. The 5 litre size provides coverage of approximately 3.6 square metres depending on surface texture and application thickness. This makes it suitable for medium sized roofing projects, repair jobs and maintenance tasks where a larger quantity of adhesive is required. It offers efficient usage for sealing larger roof areas or multiple repair sections in a single application. Designed specifically for exterior use, this roofing felt adhesive delivers strong resistance against rain, wind and changing weather conditions. It is ideal for extending the lifespan of roofing systems by reinforcing weak points, sealing joints and securing protective felt layers. Its solvent based bitumen formulation ensures deep surface penetration and long lasting adhesion performance. Everbuild Sika Black Jack Bitumen Roof Felt Adhesive 904 is a trusted solution in roofing construction due to its combination of strength, flexibility and weather resistance. It supports both preventative maintenance and repair applications, ensuring roofs remain sealed, protected and structurally sound over time. This product is widely used in professional roofing environments as well as for domestic repair work where dependable waterproof bonding is required. It ensures consistent performance across a variety of roofing materials and conditions, making it an essential component in effective roof maintenance and installation systems.
