REC A-301-50 Butyl Sealing Tape 10m x 50mm

The REC A-301-50 butyl sealing tape is a professional-grade solution designed for creating durable, airtight, and watertight seals in various construction and repair applications. Measuring 10 meters in length and 50 mm in width, this tape offers a consistent and reliable performance for both indoor and outdoor projects. Its high-quality butyl rubber composition ensures excellent adhesion to a wide range of materials, including metal, glass, concrete, and plastics, providing a robust barrier against moisture, dust, and air infiltration.

The primary advantage of this sealing tape lies in its exceptional elasticity and long-term stability. It remains flexible over a wide temperature range, which prevents cracking or peeling even when subjected to thermal expansion or contraction of the underlying surfaces. The tape is easy to apply, requiring no specialized tools, and provides an immediate seal upon contact. Its resistance to environmental degradation ensures that the integrity of the seal is maintained over many years, making it a cost-effective choice for long-term maintenance and installation tasks.

Suitable for

• Sealing joints in roofing and facade systems
• Installation of windows and doors to prevent air leaks
• Repairing cracks in gutters and downpipes
• Sealing ventilation ducts and HVAC components
• General waterproofing tasks in construction and automotive repairs

This product may not be suitable for applications involving constant immersion in water or high-pressure environments. It is also not intended for use on surfaces contaminated with oil, grease, or loose debris, as these will prevent the adhesive from forming a proper bond.

Key specifications

• Length: 10 meters
• Width: 50 mm
• Material: Butyl rubber
• Adhesive: Yes, self-adhesive
• Application: Waterproofing and airtight sealing

How to use

Before application, ensure that the surface is clean, dry, and free from dust, oil, or grease to guarantee optimal adhesion. Cut the required length of the tape from the roll and remove the protective backing paper. Press the tape firmly onto the surface, starting from one end and moving along the joint to avoid air bubbles. Once applied, use a roller or firm hand pressure to ensure full contact across the entire width of the tape.

What to consider before purchase

• Verify that the 50 mm width is sufficient for the specific joint or gap being sealed
• Ensure the surface material is compatible with butyl-based adhesives
• Check if the application area requires resistance to specific chemicals or extreme heat

Usage recommendations

For best results, apply the tape at temperatures above 5°C. If working in colder conditions, slightly warming the tape or the surface can improve initial tack and flexibility.
