The application of wax to the top back edges of the screen will help reduce “sticking” of the upper most wraps of the roll. The screen should be in the full down position before applying wax. In some more extreme cases, the motor’s down limit switch should be used to further deploy the screen a few more inches. This will allow the wax application to reach the upper most areas of the screen’s back edges.   

Some projection screen’s upper edges will stick; fail to smoothly release, during deployment. Typically, this occurs in warmer environments or on screens that are cycled less frequently. The fix is quite simple and effective.

Apply a thin coat of wax to the upper back edges of the screen. You can use an automotive paste or liquid (cream) wax. Apply the wax coat (approx. 2 to 3 inches wide) to the top backside edges from the roller tube down about 3 feet on smaller screens and up to 5 feet on larger industrial screens. This wax application will reduce or eliminate the upper edge sticking problem improving the screen’s deployment. In more extreme situations a second coat of wax may be required at a later date to ensure best screen deployment.
