First you need to prepare the frame to receive the new screening material. This will involve cleaning and checking the frame.
- Using a small screwdriver (or a nail), pry up and remove the old spline from frame. If it is in good shape (not brittle, dried out or broken) it may be carefully reused.
- If the spline needs replacement use new vinyl spline material being sure to purchase the proper width for use with the frame.
- Remove old screen material.
- Use a carpenter's square to check and make sure the frame is square (corners at right angles) and straight.
