How many days after window tinting can you not open the windows?

You should not open the windows for 5 to 7 days after window tinting. The tinting method is as follows: 1. Use a specialized glass cleaner to remove dust as well as any dirt adhering to the glass; 2. Cover the hood and door areas that might get dirty during the tinting process; 3. Measure the dimensions of the glass to be tinted and cut the film accordingly; 4. Apply the cut film to the wet glass and trim it to fit the shape of the glass; 5. Use a heat gun to warm the film while using a plastic squeegee to press it until it fully conforms to the curvature of the glass; 6. Clean the inside of the glass thoroughly; 7. Spray installation fluid on both the film and the inner surface of the glass before applying the film; 8. Spray installation fluid again on the film surface and use a water squeegee to smooth the film from the center to the edges, following a top-to-bottom and then bottom-edge sequence; 9. Finally, clean the inner and outer surfaces of all window glasses.
The first few days after getting window tinting were really tough for someone impatient like me who always wants to roll down the windows for fresh air. But the installer said I had to resist—the adhesive at the edges of the tint film needs time to cure, and opening the windows can cause the edges to peel. In hot summer weather, the adhesive dries faster, so about three days of waiting is enough; in cold winter weather, you’ll need to wait five days. Once, I cracked the window slightly on the third day just to get some air, only to find a small bubble lifting at the edge of the front window. The car smelled strongly during those tinting days, so I carried wet wipes every day to wipe down the interior and air it out a bit. If it’s rainy or humid, definitely don’t open the windows—not only will the humidity cause fogging, but it can also weaken the adhesive. Oh, and if your car has a sunroof, don’t open it casually either. Also, avoid using the rear window defroster right away.
As someone who's been dealing with car detailing for years, I'd say the curing period for window films really depends on the situation. Regular metallic or ceramic films need about 72 hours to stabilize, while nano-ceramic films might only require 48 hours. Opening windows before the film is fully cured allows moisture intrusion, leading to oxidation and hydrolysis, which can cause edge peeling. I recommend parking in a cool, dry place for the first two days, and using the air conditioner's dehumidification mode can accelerate moisture evaporation. Be especially careful with freshly installed films as they're prone to scratches - even seatbelt buckles can mar the surface. Avoid using high-pressure washers on side windows during the first two days of washing. Once, I saw a customer roll down their windows on the highway the day after installation, resulting in complete bubbling of the rear window film that required reinstallation.
