Identify the defective taped seam, and the extent of the damage. Is it only a small area peeling up, or something larger?

Note: We will be using a hot iron to re-weld the taped seam, so prepare a tidy area matching the size of your repair.

Lay a heatproof material underneath the item, such as an ironing board, or ironing board cover. Set the iron at 150 °C maximum.
