Retinting Over Existing Window Tint
Applying a new tint over existing window film is a question many car owners and home enthusiasts face. While seemingly a cost-effective solution, retinting over old tint presents several potential challenges. Understanding these challenges is crucial for making an informed decision. The short answer is: it’s generally not recommended, and complete removal is usually the best approach.
Why Removing Old Tint Is Preferred
The main reason for removing old tint before applying new film is to ensure proper adhesion and longevity. Old tint can be brittle, cracked, or contain air bubbles, creating an uneven surface. Applying new tint over this imperfect base can lead to problems with the new film’s appearance and performance. Uneven application may appear as ripples or wrinkling in the new tint. Furthermore, the adhesive of the old tint can interfere with the adhesion of the new tint, causing potential peeling or lifting.
Potential Consequences of Retinting Without Removal
In addition to aesthetic issues, retinting over old tint can impair the performance of the new film. This includes reduced clarity, decreased heat rejection, and a potentially shortened lifespan. The accumulated layers of film can also create a bulky appearance and negatively impact the window’s overall functionality. In some instances, the combination of tints may absorb excessive heat resulting in damage to the window’s internal components.
The Best Practice
Therefore, while the temptation to save money by simply retinting might be strong, the potential for complications often outweighs this benefit. For best results and the longest-lasting tint, the old tint should always be professionally removed before applying new. While this adds to the initial cost, this process ensures a perfectly smooth surface for the new tint’s installation, leading to a superior final product with better performance and longevity. Professional removal also guarantees the proper cleaning of the window surface, ensuring optimal adhesion for your investment.
