Amalgamating tape, also known as self-fusing or self-amalgamating tape, is a versatile and handy tool to have in your toolbox. This type of tape is used to create a water-tight seal around a variety of surfaces. It is commonly used in plumbing, automotive, and electrical applications.

2. Stretch the tape Most amalgamating tapes come on a roll and need to be stretched before application. Gently stretch the tape to activate the adhesive properties.

To use the tape, simply stretch it around the material you are trying to repair. As you wrap the tape in a circular motion, it begins to seal and “fuse” itself to the material. The most common forms of self-fusing / self-amalgamating tapes are made of silicone rubber (though other types also exist). They are designed to create a strong, seamless, rubbery, waterproof, and electrically insulating layer.
