paint protection film blistering

After installing and pasting the ppf, a small number of car owners found that there were small white spots under the film. On closer inspection, they found that there were small bubbles (or blisters). This blistering phenomenon sometimes occurs when the clear film is just pasted, and sometimes after several months.

Causes of blistering in paint protection film

The reason why the clear car bra bubbles is that there are things inside, such as water, air, sand, dirt, etc.The root causes of this situation are basically in these two aspects:

1.Membrane products

Some inferior paint protection films will volatilize gas under the action of light (ultraviolet), causing blistering.


In the non-dust-free construction room, no dustfall cleaning (or cleaning) was carried out during the construction period, and sand particles and dirt remained, resulting in blistering;

During the construction of the car ppf, the water and blisters were not completely driven out, resulting in blistering (this kind of situation usually disappears in about a week under the sun).

How to solve blistering of paint protection film?

1.To remove bubbles from paint protection film, follow these steps:

Heat the area: Use a heat gun or a hairdryer to gently heat the area with bubbles. This will help to soften the adhesive and make it easier to manipulate.

Press out the bubbles: Use a squeegee or a credit card to press out the bubbles from the center of the bubble towards the edges. Work slowly and carefully to avoid creating more bubbles.

Apply pressure: Once the bubbles have been pressed out, use your fingers to apply pressure to the area to ensure that the film is securely adhered to the surface.

Wait and reapply if necessary: Wait for a few hours to allow the adhesive to set. If you still see bubbles, repeat the process again until all the bubbles are removed.

Trim excess film: If there is excess film, use a sharp blade to trim it off.

Note: Be careful not to overheat the film, as this can cause it to stretch or distort. If the bubbles are too large or the film is damaged, it may be necessary to replace the film entirely.
