This type of tape is a self-adhesive sealant that is commonly used for waterproofing and repairing leaks.
It is made from butyl rubber, which gives it strong adhesive properties and makes it resistant to extreme weather conditions.
Butyl tape is often used for sealing joints and cracks in roofs, windows, pipes, and other construction projects.
The tape is designed to be airtight and watertight, providing a long-lasting and secure seal.
The text on the packaging indicates it is for use on roof cracks, balcony corners, and color steel tile roofs, and that the surface should be clean and dry before application.
