FAQs

What is the primary use of Drybase Overseal Tape?

Its primary use is to seal joints between cavity drain membranes, particularly at the junction of floor and wall membranes, and around service penetrations to ensure a waterproof barrier.

What makes this tape suitable for ground gas protection?

When used in combination with Drybase Double-Sided Sealing Tape, it can create a double-seal, which provides heightened protection against ground gases such as radon.

Can this tape be used on wet surfaces?

No, the tape requires clean and dry surfaces for proper adhesion. Surface preparation is critical for its performance.

What is the width of the tape and what is it best suited for?

This specific product is 150mm wide, making it ideal for sealing flange joints on floors and for lapping floor membranes to wall membranes.

How is the tape supplied?

It is supplied in rolls, with this particular product being 20 meters long and 150mm wide.

What is the backing material of the tape?

The tape has a robust adhesive layer with a backing paper that is removed before application.

Is the tape flexible?

Yes, the tape is designed to be flexible, allowing it to conform to irregular surfaces and details.

Troubleshooting

Tape not adhering properly

Ensure the substrate is thoroughly cleaned, dry, and free of dust, grease, or moisture. Re-apply pressure using a roller.

Poor seal at corners or details

Cut the tape to fit snugly around corners or details, ensuring no gaps. Apply gentle heat if necessary to improve flexibility for intricate areas, but avoid overheating.

Difficulty cutting the tape

Use a sharp utility knife or heavy-duty scissors for clean cuts. Ensure the tape is laid flat when cutting.

Setup:

  1. Ensure all surfaces to be sealed are clean, dry, and free from dust, debris, oil, or any contaminants.
