Sometimes you don't want buttons or nests but you just want to put a nice zipper in the latex outfit.
That is not possible with the normal latex glue unfortunately because then your zipper will come loose. This glue is ideal for using zippers ... it is completely wall-proof!
In addition to this glue, you also need the regular latex glue if you are going to place the zipper in the latex. The zip glue/liquid latex gives a latex coating over the textile. Then you treat it as being latex.
