Sealing Tape Deka Alubutyl roofing tape 10 cm × 10 m, brick red

Deka Alubutyl sealing roofing tape 10 cm × 10 m in brick red is a self-adhesive aluminum-bitumen composite tape designed for watertight sealing and on-site repairs on roofs. The tape combines a flexible bituminous adhesive layer with an aluminum outer film to resist weather exposure while conforming to irregular surfaces. Supplied in a convenient roll, it is intended for sealing roof joints, flashings, chimneys and for repairing metal, bitumen and profiled sheet materials.

Advantages

The aluminum-bitumen construction ensures reliable adhesion to a variety of common construction substrates and provides immediate water resistance after application. The roll format simplifies transport and local repairs, while the brick red outer film helps the tape blend with many roofing finishes. The tape’s flexibility allows it to conform to seams and curved surfaces, and its self-adhesive backing removes the need for primer or additional fixing in many repair scenarios.

Suitable for

• Sealing roof joints and overlaps
• Waterproofing flashings around chimneys and vents
• Repairing tears and holes in metal, bitumen and profiled roofing sheets
• Temporary or permanent on-site patching and detailing

Key specifications

• Width: 10 cm
• Length: 10 m
• Composition: aluminum outer film with bitumen-based adhesive layer
• Color: brick red
• Format: self-adhesive roll
• Application temperature range: suitable for typical outdoor installation temperatures (surface must be dry and free of loose debris)

How to use

Ensure the surface is clean, dry and free from dust, rust scale and loose material. Cut the required length from the roll and remove the protective backing to expose the adhesive. Position the tape over the joint or damaged area and press firmly, smoothing from the center outward to remove air pockets. For curved or profiled surfaces, warm the tape slightly (if ambient temperature is low) to improve conformability and adhesion. Overlaps should be pressed tightly to ensure a continuous seal.

Usage recommendations

For best performance, apply the tape on surfaces that are as dry and clean as possible; avoid applying during heavy rain or freezing conditions. When repairing actively leaking areas, temporarily reduce water flow before applying and allow time for adhesion. On long-term structural applications, verify compatibility with the existing roofing materials and consider mechanical fixation in high-wind zones.
