Learn moreSika Black Jack 904 is a cold-applied, oxidised bitumen-based adhesive designed for securely bonding roofing felt to surfaces including metal, concrete, timber and existing roofing felt. Offering high bond strength, it forms a tough yet flexible film that responds to changing temperatures, making it a practical choice for horizontal roofing applications.
Supplied in a 5L tin, Sika Black Jack is suitable for sealing roofing felt laps, and can also be used as a cold-gritting adhesive for securing mineral chippings to the final felt layer. No heating is required before application, helping simplify installation, while the adhesive typically dries in around 24 hours, depending on conditions. Once cured, it creates a strong, flexible and waterproof bond.
Please note:
Question:
What should it be thinned with
Answer:
The Black Jack Roof Felt Adhesive is a bitumen-based adhesive and it should not be thinned. The adhesive is ready to use as it is. For more technical information, you may find the Technical Information document helpful. You can find it at this link: Technical Information. It's important to ensure that the surface to be repaired is dry and clean, free from all loose debris, rust, dirt, and grease before applying the adhesive. If you have any further questions, please don't hesitate to ask.

Hi, can you use Black Jack with Polyester Roofing Felt?
Answer:
The Black Jack Roof Felt Adhesive is designed to bond roofing felt to various surfaces including itself, concrete, asphalt, metal, and wood. However, the product description does not specifically mention compatibility with Polyester Roofing Felt. I suggest checking with the manufacturer of the polyester roofing felt for their recommended adhesive.
