Common Mistakes to Avoid

1. Using the wrong type of adhesive

Reason: Incorrect adhesive may not adhere properly to the mirror or plastic trim, leading to a weak or failing repair.
Solution: Use a strong adhesive specifically designed for bonding plastic to glass, ensuring a secure and long-lasting repair.

2. Inadequate surface preparation

Reason: Dust, dirt, or grease on the mirror or plastic trim prevents proper adhesion of the adhesive, resulting in a weak bond and potential failure.
Solution: Clean both surfaces thoroughly with isopropyl alcohol before applying the adhesive to ensure a clean and strong bond.

FAQs

What type of plastic trim is best for this repair?
Flexible, self-adhesive trim that's slightly wider than the damaged area works best. Look for vinyl or plastic trim found in home improvement stores, often used for edge banding or window trim. Avoid rigid trims that might crack under pressure.
