First, you’ll want to make sure your Eva foam is clean and free of any dirt or debris. Once it’s clean, you can start applying the glue. You can use any type of glue you like, but we recommend using a strong adhesive like super glue or epoxy. Apply the glue in thin layers, making sure to cover the entire surface of the foam.
Once the glue is applied, you’ll want to let it dry for at least 24 hours. This will give the glue time to harden and bond with the foam. After the glue has dried, you can start to shape and mold the foam into whatever shape you desire.
