Top Reasons we get 'bubbles' in Window Film - and how to fix them!

Have you ever wondered why bubbles seem to make an unwelcome appearance in window tint?

Bubbles are always aesthetically unpleasing, but in most cases they can dry within a few days, but all "bubbles" are not creating equal and are caused by different issues with the film from improper cleaning to window tint failure. 

Bubbles can be unsightly and may affect the functionality of the tint. Here are some common reasons for bubbles and potential solutions:

  1. Dirt and Debris:

    • Cause: Dust, dirt, or debris on the window or the tint adhesive can cause bubbles. We call this contamination. 
    • Solution: Ensure that both the window and the tint film are thoroughly cleaned before application. 



  1. Improper Installation Technique:

    • Cause: Inexperienced or rushed installation can lead to uneven application and bubbles.
    • Solution: Follow proper installation techniques. This may involve using a squeegee to smooth out the film and remove any trapped air. Work slowly and methodically, starting from the centre and moving outward.
    • We always want quality over quantity. A rushed job can leave pockets of air {which is space between the film and glass} which will not dry and be permanent 


  1. Low-Quality Tint Film:

    • Cause: Low-quality tint films may not adhere well or may have adhesive issues. When the adhesive in the film fails, it will leave air in between the film and glass causing air pockets. We typically see this over 2-3 years with low quality film
    • Solution: Invest in high-quality tint films from reputable manufacturers. Quality films are more likely to have proper adhesives with lifetime warranty
  2. Temperature and Humidity:

    • Cause: Applying window tint in extreme temperatures or high humidity can affect the adhesive properties. We also see this in most humid Canadian provinces during the summer where there will be humidity markings between the film and glass
    • Solution: Apply tint in a controlled environment with moderate temperatures and low humidity. 
    • These humidity markings will dry in 3-5 days {depending on climate}
    • Educate the customer and provide the proper paperwork on drying. 


  1. Adhesive Activation Time {Window Film Cure Time}:

    • Cause: Some window films require a curing or activation period for the adhesive to set properly.
    • Solution: Allow the tint to cure for the recommended time before exposing it to extreme conditions or cleaning.
    • This can take 20-30 days to fully cure on the window. In this time frame, you will see bubbles, hazing, cloudiness in the film. THIS WILL DRY
    • Educate your customer on Window Film drying and provide proper paperwork for post window film care.


  1. Old or Damaged Tint:

    • Cause: Tint that is past its prime or has been damaged may not adhere properly. We see damaged tint where customers use chemicals to clean {Windex} which is going to cause a "wave" or ripples and bubbles through the film
    • Solution: Consider replacing the tint with a new, undamaged roll.
    • Education the consumer on using Tint Safe products
