  • SEAL WINDOWS & DOORS This sealing tape can be used as window flashing tape to tightly seal off the gaps between windows/doors and the exterior of the house. By installing window flashing tape beneath your siding around your window, you can seal it from air and moisture. This can help you prevent rot, cracking and leaks in the future.

It adheres to almost any surface to create a watertight seal that is permanent.

For instance, it can be used as gutter repair tape to fix leaks in drain pipes and guttering. It can also be used to protect pipe and tank insulations, and can be used to repair green houses.
  • EASY TO APPLY BY HAND Quick and easy to apply, this waterproof repair tape is ideal for professionals and DIY beginners. The sealing tape has a flexible lamination, meaning it can be easily positioned by hand. Simply cut the tape to length, then remove the release liner before placing the tape into position. Use a seam roller to ensure all edges are firmly sealed. Do not use in temperatures below 5ยฐC (if using when itโ€™s below 15ยฐC, store the tape in a warm environment prior to use).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
