Tips

  • Check if your old spline is still flexible and undamaged before replacing it.
  • Ensure the mesh screen is flat and tight to avoid ripples or bends.
  • Be careful when trimming excess spline with the razor blade to avoid cutting the screen.

Common Mistakes to Avoid

1. Using the wrong mesh size

Reason: Using mesh that's too coarse will allow insects through, while mesh that's too fine can be difficult to work with and may not fit properly.
Solution: Choose a mesh size that matches the original screen's weave.

2. Pulling the mesh too tight

Reason: Over-tightening the mesh can cause it to tear or wrinkle, making the repair less effective and potentially damaging the frame.
Solution: Apply even tension, ensuring the mesh is taut but not overly stretched.

3. Incorrectly applying adhesive

Reason: Using too little adhesive will result in a weak repair, while using too much can create a messy, unsightly finish.
Solution: Apply a thin, even layer of adhesive along the edges of the patch and the screen frame.

FAQs

What materials do I need to repair my window screen?
You'll primarily need a piece of screen mesh (slightly larger than the tear), strong adhesive (like screen repair tape or fabric glue), and scissors. A ruler or tape measure can also be helpful for accurate cutting.
Can I repair larger holes or tears in my screen?
While this method works best for small tears, you can adapt it for larger holes by using a larger patch of screen mesh. For extremely large damage, replacing the entire screen might be more practical.
What type of adhesive is best for screen repair?
Screen repair tape specifically designed for mesh is ideal as it's strong, flexible, and designed to adhere well to the screen material. Fabric glue can also work well, but ensure it's completely dry before reinstalling the screen.
