Well, it depends on what kind of weatherstripping you're using! If it's foam or rubber, then you'll likely just need to cut it to size and press it into the cracks around your door or window. If it's a metal strip, then you'll probably have to use a staple gun or some other type of adhesive to attach it to your door or window frame. Just make sure that you read the instructions carefully before starting so that you know how to best apply the weatherstripping for your specific application. And always be careful when using tools like a staple gun - they can be dangerous if not used properly!

There are a few ways to install weatherstripping. The most common way is to use a caulking gun to apply a strip of weatherstripping around the door or window frame. You can also cut the weatherstripping to size and then adhere it with a sticky tape or glue.
