Sika Evercryl Emergency Roof Repair Compound 310ml Cartridge – Grey (EVCGYCART)

Sika Evercryl Emergency Roof Repair Grey 310ml is a resin-based, fibre-reinforced repair compound designed for fast, targeted waterproof roof repairs. Applied from a standard sealant gun through the shaped nozzle, it forms a flexible waterproof membrane and is particularly suited to cracks, holes, gaps and detailed roof repairs where a full roof coating is not required.

Best For Visible Grey Roof Repairs

Choose the grey cartridge when you need a targeted, fibre-reinforced waterproof repair for smaller cracks, holes, gaps and roof details. The cartridge format allows controlled application directly to the repair area, while the incorporated fibres help bridge small defects.

• Small roof leaks and local waterproofing defects
• Cracks and holes up to 5mm where fibre reinforcement is beneficial
• Gutters, flashings, upstands, vents and roofline details
• Emergency repairs in damp or wet conditions

Why Choose Grey Evercryl

Grey Evercryl provides a visible, fibre-reinforced waterproof repair finish for targeted roof maintenance. The cartridge format is suited to smaller repair areas where controlled application is more practical than opening a larger tin, while the shaped nozzle helps spread the compound across cracks, gaps and holes.

Key Benefits

• Fibre reinforced: Incorporated fibres help bridge small cracks and holes up to 5mm.
• Instant waterproofing: Provides waterproof protection immediately after application.
• Ready to use: Cartridge applied using a standard sealant gun without mixing.
• Wet-weather application: Can be applied in damp and wet conditions and at ambient temperatures down to -5°C.
• Controlled application: Supplied with a shaped nozzle to spread the compound across local repair areas.

Where It Can Be Used

Suitable for sealing, maintaining, repairing and waterproofing common roofing substrates including concrete, fibre cement, roofing felt, mastic asphalt, existing bituminous roof coatings, rigid uPVC, corrugated iron, metals, slates, brickwork, tiles, lead, copper and zinc. It can also be used on plastic and metal guttering, downpipes, gullies, flashings, upstands, vents and leadwork.

How To Apply

Always read the current Product Data Sheet and Safety Data Sheet before use.

• Inspect the repair area: Repair or refix unstable, damaged or structural defects before applying the compound.
• Prepare the surface: Ensure the area is sound and stable and remove loose debris, dirt, dust, grease, algae and other contamination.
• Prime where required: Non-bituminous, porous or friable surfaces may require a suitable primer in accordance with the Product Data Sheet.
• Prepare the cartridge: Cut the cartridge tip carefully without damaging the thread and attach the supplied shaped nozzle.
• Apply with a sealant gun: Load the cartridge into a standard sealant gun and apply the compound directly across the crack, gap, hole or repair area.
• Second application if required: In extreme cases, a second application may be made 2-3 days after the first.
• Allow to cure: Typical curing time is approximately 24-48 hours, although the product provides waterproof protection immediately after application.

Choosing Grey Or Clear

Choose Grey where a visible grey, fibre-reinforced waterproof repair finish is suitable. Choose the clear/translucent cartridge where a more discreet finish is preferred. The 310ml cartridge format is particularly suited to isolated cracks, holes, gaps and detailed repair work, while larger Evercryl pack sizes may be more appropriate for broader repair areas.
