Mylar is a polyester film used in many industrial applications. It has a high tensile strength, chemical stability, electrical insulation properties, and is a gas and aroma barrier. The bright, metallic appearance of Mylar has also led to its being a popular choice for crafts and models. Most adhesives and glues will peel off the surface of Mylar once dry. Contact cement will continue to adhere to Mylar, which makes it the best way to glue Mylar to other objects.
Spray the side of the Mylar being glued with contact cement.

Spray the surface of the object with contact cement and wait 30 seconds.
Place the side of Mylar covered in contact cement onto the object. The Mylar will almost instantaneously be glued to the object once the contact cement sides touch.
The surface of the Mylar and object must be free of dirt before applying the contact cement. Dirt will become trapped between the Mylar and object, creating bumps on the surface of the Mylar.
Contact cement will bond almost instantaneously when used. Be careful to smoothly lay the object onto the Mylar when gluing the two together. You will usually not be able to smooth out any air bubbles that form.
Use spray contact cement in a well ventilated area. Avoid inhaling any fumes when spraying the contact cement.
