Deflate the air bed and clean the area around the leak with a cotton ball dipped in rubbing alcohol. Let the cleaned area dry completely before patching.
Measure and cut the vinyl patch 1 cm larger than the hole.
Dab the vinyl glue over the leaking area just a little larger than the size of the patch. Use your finger or a cotton swab. Wait one minute for the glue to set.
Apply an equal amount of glue to the patch.
Apply a second dab of glue to the hole and around it.
Stick the patch, glue side down, to the hole in the air bed. Allow the patch to bond to the air bed for 30 minutes.
