Next cut out a square of thin plastic big enough to extend a centimeter past the hole on every side from something like a shower curtain or tarp.
What type of glue to use on air mattress.
After some time the glue on the duct tape will come out as it will not permanently bind it to the plastic.
Otherwise you will melt the air mattress and have a much bigger problem.
Insert a glue stick into a low temp glue gun.
Be careful when applying the hot glue not to let the tip of the glue gun make contact.
You can also buy patch kits at mass merchandisers and online or use a bicycle tire repair.
Plug the glue gun in and allow it to fully heat up.
While they are made mostly from durable materials air beds are prone to getting tiny holes.
Avoid using hot glue when fixing the leak as it will melt part of the air mattress and enlarge the hole.
Remove any tape from the hole in the air mattress if you used it to mark the spot.
You can decide to use duct tape and even though it is effective in the short term.
To patch a leak in an air mattress start by using sandpaper to lightly scrub away the soft felt on the surface of the mattress around the hole to help the glue stick better.
It will dry and fall.
