Description
Sika® Black Jack®-905 All Weather Roof Coating is a solvent-based, full-bodied, black bitumen compound reinforced with fibres, designed for general waterproofing of roofs, guttering (non-plastic), and structural steelwork. It dries to a tough, durable black coating and is resistant to rain wash-off almost immediately, making it ideal for winter use. The product can be applied by brush to a wide variety of roof surfaces. This includes asphalt, built-up felt, concrete decks, cement sheeting, metal sheets (iron, steel, zinc, and lead), slates, and tiles. It may also be combined with rot-proof hessian or bitumen-coated glass fibre scrims for reinforcement and can function as a vapour barrier on walls and roofs.
