How long tint takes — and what the haze afterwards means

Two questions come up at pickup more than any others: how long did that take, and why does it look like there's water under my back window. Here's both answers.

Install day

How long the car is with us depends on the vehicle and how much glass it has. Most of the work isn't laying the film — it's preparing the glass. Anything left on the glass ends up trapped under the film permanently, so the cleaning stage is not the place to save time.

We'll give you a realistic window when you book, and we'd rather quote you honest hours than rush a rear window.

Why it looks hazy at first

Film is applied with a water-based solution. A thin layer of that moisture stays between the film and the glass when you drive away, and it has to evaporate out through the film. While it does, you'll see haze, cloudiness, or small pockets that look like bubbles or water blisters.

That's normal, it's not a fault, and it clears on its own. Small pockets on rear glass are the last to go.

Don't roll the windows down

This is the one that matters. Until the film has bonded, running a window down can drag the edge of the film out of position. A few days is the safe answer, and longer in cold weather — curing is slower when it's cold.

How to clean it afterwards

• Wait until the film has fully cured before cleaning the inside of the glass.
• Use an ammonia-free cleaner. Ammonia breaks down the film's adhesive and is what turns tint purple and hazy over time.
• Use a soft microfibre, not paper towel or anything abrasive.
• Be careful along the top edge when the window is down — that edge is the vulnerable one.

Any concerns while it's curing, bring it back and we'll look at it. See our window tint service →
