It bonds to a wide range of roofing materials, dries quickly to resist rain, and withstands extreme temperatures from -10°C to +75°C. Ideal for flat, pitched, and felt roofs, this professional-grade sealant offers a flexible, long-lasting barrier against leaks and weather damage, making it the go-to solution for emergency and planned roof maintenance. ## Description Product description When a roof starts letting water in, you need a repair that works in real British weather, not one that waits for a dry week. Master Bitumen All Weather Roofing Compound is a heavy duty, fibre reinforced bitumen paint and roof sealer that seals out rain almost immediately after application, making this black bitumen paint the dependable choice for emergency roof repair and planned maintenance alike, whatever the season. This thick, brushable bitumen sealant works as a felt roof sealant, a roof sealer waterproof against driving rain, and a liquid roof coating for flat and pitched roofs, where you might otherwise reach for a liquid rubber roof coating or rubber roof sealant. Use it to re-seal roof felt for sheds, garages and outbuildings, a shed paint waterproof enough for any garden building, or for asphalt repair, roof felt repair and concrete repair on cracked decks. It bonds to asphalt, bitumen, concrete, felt, metal, slate, tiles and asbestos cement sheeting, sealing joints in guttering and metal sheeting, including iron, steel, zinc and lead. Combine with a rot proof hessian or glass fibre scrim as a complete flat roof repair kit for cracks and splits. The compound also doubles as a damp seal paint, damp proof paint and liquid DPM style vapour barrier on concrete decks. Apply two to three coats by brush or spray equipment at 1.0-1.5m² per litre per coat. With a service temperature of -10°C to +75°C, this black waterproof paint stands up to frost, rain and heat year after year. Supplied as a bitumen paint 25L pack, also available in 5L.

Consult the epdm manufacturers for professional advice. **Q: any good for a felted shed roof ? it's a new shed but leaks like a shive .** A: It is a fairly low viscosity compound so not ideal for a pitched roof as it will run. I used it on a flat roof and that was fine. **Q: Can you apply decorative gravel on top?** A: You only really do chippings with a Bitumen gritting solution,this is a roof coating not an adhesive **Q: Is it 'pourable' through a funnel?** A: Depending on how large the spout is in the funnel and if it were a warm day it would run slowly through a funnel but less likely on a cold day. It will need a good stir first and then put it in the sun or in a warm room.
