Spray Adhesives

Spray adhesives are great for providing a smooth even adherence, but they are very toxic, and expensive. Here are some tips for using a spray adhesive.

• Spray adhesives can be used by applying to the heavier of the two materials you are attaching, and placing the lighter material on to the other before the glue has dried. This is fast, but if you are attaching a large area it can be difficult.
• You can also use a spray adhesive by applying to both materials you are attaching, allowing them to dry to the touch, and then attaching them together. This technique is called "contact adherence".
• When using a spray adhesive as a "contact adherent" the two materials bond instantly on contact. It is difficult, if not impossible, to break the bond once the materials have made contact.
• Unwanted wrinkles can be prevented by folding the top material in half or quarters and applying in manageable amounts. Make sure the material is positioned accurately before you fold it in half.
• If you do get a wrinkle, you can soften the glue with a hair dryer, and carefully rub the wrinkle towards the edge.
• If you are using a spray adhesive on a small area, you may need to mask off this area to prevent over spray. Brown paper bags work well as a masking, or of course, masking tape!
