There are several kinds of tape specifically engineered for use with EPDM liners. EPDM tape is a particular kind of tape made to be used with EPDM liners. This is made out of the same material as the liner itself and can be used to seal seams or repair small tears and punctures. Butyl tape is another kind of sealant tape that is often used in construction and other scenarios where a waterproof seal is needed.
Lastly, some people use seam primer and seam tape which is specifically designed for use with EPDM liners. The primer is applied to the surface of the liner to help the tape adhere, and the tape is then applied over the seam to create a watertight seal.
