Deflate the Aerobed completely. Once all the air is gone, use a mild household detergent, a sponge and water to clean the surface of the mattress. Let it air dry completely.
Cut the vinyl patch in the repair kit to one inch larger than the size of the tear.
Apply glue directly to the Aerobed. It should cover an area 1/4 inch larger than the entire size of the patch. Apply glue to the bottom of the vinyl patch also.
Wait one minute. Press the patch against the mattress and push it flat against a hard surface with the palm of your hand. Hold it down for 10 seconds.
Rub your fingers over the patch, working from the center to the edges. This removes trapped air from under the patch.
