5 Tips to Help With Mitering Corners

When you’re doing any kind of weatherstripping project- especially a custom project- there’s a good chance you’ll encounter Mitering. Mitering is a fancy term for cutting 2 pieces of weatherstripping and joining them together at a 90-degree angle, like the border of a picture frame.

We’re very familiar with this process and have gathered up our top 5 tips for mitering corners to help you with this detailed part of your project.

Tip #1: Use a 90-degree angle and silver pen to mark the weatherstrip where it needs to be cut. So long as you can cut on the lines, you’re good to go!

Tip #2: Use a straight razor blade or mitering scissors to make the cut. The sharper the blade, the cleaner the cut.

Tip #3: If you don’t have to cut all the way through the weatherstrip, then don’t. Just bend the weatherstrip at the corner joint to match up the 2 sides and then apply adhesive to stick them together. This will allow you to have a continuous seal all around the outside edge.

Tip #4: Join the ends together with Loctite 495. It’s made to join rubber to rubber and will give you a nice clean seam and sealed joint.

Tip #5: When making a glass gasket, use a template or piece of wood or metal to guide the rubber together when you glue your ends. This will ensure an even gap for your glass and help everything line up perfectly.

Bonus tip: It never hurts to get a little bit of extra material to do a trial run before you cut and glue the weatherstrip for your project.
