Directions for Contact Cement

Contact cement instantly bonds, making it ideal for building model cars and planes.

Contact cement is a strong adhesive that is typically used to bond surfaces that can't be clamped together, such as chair covers or model cars. It bonds laminates, metal, rubber, Masonite, ceramics and particle board. Once it has dried, contact cement provides a water proof, permanent seal. Using contact cement isn't difficult, but you do have to follow a few basic steps.

Things You'll Need

• Gloves
• Rags
• Applicator brush
• Nail polish remover
• Utility knife

Instructions

1. Cover your clothes and your work surface before using contact cement. Wear gloves to avoid getting the contact cement on your skin.

2. Open the container. Keep it away from your face and open slowly to vent vapor pressure inside the container.

3. Stir the contact cement using the applicator brush provided by the manufacturer. It should become uniform in color.

4. Clean and dry the surfaces that you are joining. Bonding will be difficult if the surface is sandy or has particles of dust, paint, etc. Sand painted or finished surfaces to ensure better adhesion.

5. Brush the contact cement onto both surfaces. Apply a generous and even coat and wait 10 minutes for the cement to cure. If surfaces are left too long and the cement dries, apply another coat to reactivate the contact cement and wait again for it to cure. When ready to bond, the contact cement will have a clear glossy color.

6. Press surfaces together firmly and wipe away any excess contact cement using nail polish remover and a rag.

7. Allow the cement to dry for at least 30 minutes.

Tips & Warnings

• Contact cement that is dry and ready for bonding will have a uniform glossy appearance. If you see dull spots, you'll have to apply another coat. Dull spots indicate that you haven't applied enough adhesive or that the adhesive has been absorbed into the surface.

• Bonding is immediate, and surfaces cannot be moved once they've been in contact. Position surfaces carefully so that you get the right bond the first time.

• Cured contact cement can be cut away with a sharp edge, such as a utility knife.

• Use contact cement in well-ventilated areas and store away from heat or flame. Avoid breathing vapors for a prolonged period.

• Do not mix contact cement with other adhesives and do not dilute it with water.
