If your bounce house is accidentally punctured, you'll need a patch kit to fix it up. While some bounce houses do come with their own repair kit, it's not always guaranteed. If your particular bounce house doesn't come with one, you can still buy an independent patch kit from retailers like Amazon—they're relatively inexpensive and easy to use for small tears. Just make sure your patch repair kit is designed specifically for bounce houses. For larger tears, it may need restitching with a sewing awl or a professional repair job. In order to patch a small puncture, start by cleaning the area around it so your patch will fully stick. Cut a small, round patch from your repair kit and flatten it all the way. Apply vinyl glue around the hole in your bounce house and to the patch. Press the patch firmly on and apply pressure to it for a few seconds. Check to make sure that the edges of the patch are sealed and no air is escaping from the area anymore.
