Cement splicers use a liquid film cement that consists of film base dissolved in a solvent. Typically, the film is cut so that each end overlaps by one perforation, with one side of the overlap falling on a frame line. Cement splices are performed with the emulsion up. The emulsion and binder on the lower layer are scraped off, and the base of the upper layer is abraded to provide a rough surface for the cement to adhere to. Cement is then applied and the two pieces of film are clamped together while the cement cures. Hot splicers are cement splicers that have a built-in heating element to speed up the curing process. | Cement splicers use a liquid film cement that consists of film base dissolved in a solvent.

When cement splices are beginning to separate or experience other issues, they may be reinforced with repair tape. In most cases, the tape should be applied to the emulsion side of the splice to cover the leading edge, which could catch in the gate. | When cement splices are beginning to separate or experience other issues, they may be reinforced with repair tape.
