A: 3.5mm thick, 1 inch wide and 33 feet for roll size. The butyl tape is double sided, putty like for water and air tight seal.

**Q: Hi can I use around the bath**
A: Not designed for a bath but there are similar products that are designed for baths

**Q: Could I use this to stop a leak in a shower from between grout, there is movement on the shower tray so I need something flexible?**
A: I would certainly give it a try. Ive used it my windscreen where the seal has perished. works great. Not sure how easy it is to remove. Might use on my shower when the glass has broken free of the old mastic. Bought it to fix the rainscreen back into the car doors. Perfect.

### ⭐⭐⭐⭐ Well packaged
*by R***T on 23 March 2026*

The manufacturer has put lots of thought into the packaging, to ensure the putty tape stays well formed, and doesn’t get damaged in transit. I’d certainly buy this again. Even better if it was available in white.
