The best way to repair a hole in a leaky vinyl air mattress is using a repair kit created for the item, but warm glue can stop the air leakage and temporarily repair the harm in a crisis. After locating the hole in the bed, it is ideal to use a low-temp glue gun to stop damage to the plastic, which is a form of plastic.
Inflate the bed as much as you can and listen for escaping air around the seams and all over the surface to find the hole. If you can’t hear any escaping air, dip a kitchen sponge into a soapy water solution and then rub the sponge gently above the mattress surface, then starting with the seams, then to observe where bubbles form. Wipe the bed dry using a soft cloth and mark the hole using a bit of tape or a marker.
Insert a glue stick into a low-temp glue gun. Plug the glue gun in and allow it to fully heat up. Remove any tape from the hole at the air mattress in the event that you used it to mark the spot.
Squeeze the face of this glue gun and gently put a small dab of hot glue over the hole to temporarily patch it up.
Allow the hot glue to fully dry before using the air mattress again.
