Sealing tape Tesa 200-13403 66×50 mm — white, 66 mm width, 50 m length

Sealing tape Tesa 200-13403 66×50 mm is a white adhesive tape designed for creating airtight and watertight seals on joints, window and door frames, and other connections in building and repair work. With a 66 mm width and 50 m roll length, the tape is suitable for continuous sealing runs and patch repairs. The product provides reliable adhesion to common building materials and is intended for applications where moisture resistance and prevention of drafts are needed.

Advantages

The tape combines a wide 66 mm backing with a pressure-sensitive adhesive that adheres to wood, metal, painted and unpainted plaster, and many plastics. Its 50 m length allows for multiple installations from a single roll, reducing the need for frequent replacements. The white colour offers a discreet finish on light-coloured surfaces and can be painted over in many cases to match surrounding surfaces. The product is suitable for both DIY repairs and professional sealing tasks where a consistent, durable seal is required.

Suitable for

• Sealing joints around window and door frames
• Creating airtight connections in ventilation and ducting repairs
• Patching small leaks and preventing drafts
• Temporary or permanent sealing on construction materials

Key specifications

• Colour: white
• Width: 66 mm
• Length: 50 m
• Adhesive type: pressure-sensitive adhesive (self-adhesive)
• Intended use: sealing joints and connections, moisture-resistant sealing

How to use

Ensure that the surface is clean, dry and free from dust, grease or loose particles before applying the tape. Measure and cut the required length, then press the adhesive side firmly onto the substrate while smoothing out any air pockets to ensure full contact. Overlap joints where necessary to provide continuous sealing. For best results, apply at moderate temperatures and avoid stretching the tape during application. If painting over the tape is required, test compatibility with the chosen paint on a concealed area first.

Recommendations

For durable results, store the roll in a dry place away from direct sunlight and apply the tape to surfaces at temperatures recommended for adhesive application (typically above freezing). When sealing exterior joints, combine with appropriate building tapes or sealants for long-term weather resistance. Regularly inspect sealed areas and replace the tape if adhesion degrades over time.
