If you’re wondering which tape should you buy, consider self-adhesive butyl tape. It’s much easier to install, meaning no fiddly application and less chance of getting yourself stuck.

The tape fuses or seals itself to create a waterproof and airtight layer when stretched and wrapped around objects.
No protective equipment or specialist tools are required to use self-amalgamating tape, and a pair of scissors to cut the tape is all that is needed. The tape features a peel-away backing paper (to stop it from sticking to itself before needed) that has to be removed prior to use. Once the correct length has been cut, and the backing removed, the tape can be stretched and applied; when the tape is being wrapped around a cable, for example, ensure that each layer overlaps the previous. Overlapping in this way enables a stronger bond between layers and a 50% overlap is usually recommended, with 3-4 layers of tape being advised. Stretching the tape as you go will ensure a tighter wrap is created and will help the tape to stick to itself more effectively. The bond between the layers of tape will usually take only a few minutes to form but is capable of enduring for years.


When you think of types of electrical tape, you probably imagine it in black. However, manufacturers produce electrical insulation tape in almost every color of the rainbow. The varying colors indicate voltage protection and insulation. It’s vital to use the right colored tape—an incorrect tape color puts technicians at risk of insufficient voltage shielding:
The effectiveness of insulation tape hinges on several key characteristics
