What kind of water is sprayed during car film installation?
2 Answers
Car window film installation uses a spray solution containing a certain proportion of purified water. Below are extended guidelines for car window film installation precautions. 1. Before installation, check that the window glass is intact and the overall condition of the car glass to ensure smooth film application. Always cover necessary interior parts to prevent liquid penetration. 2. Clean both inner and outer surfaces of the windows before installation. 3. Avoid rolling windows up or down for 3 days after installation. 4. Do not clean the heat-insulating film or activate the defroster switch for one week after installation. 5. Do not use alcohol or ammonia-based solutions to clean the film surface. 6. If bubbles appear after installation, they must be addressed at the installation shop within 24 hours. 7. Avoid directing air conditioner airflow directly at the film to prevent severe thermal expansion and contraction.
The water I spray when applying car film is actually diluted soapy water, most commonly made by mixing baby shampoo with water at a ratio of about 1 part shampoo to 10 parts water. It produces little foam and isn't too slippery. Its purpose is to spray it on the glass or the back of the film, allowing the film to slide smoothly for alignment without getting stuck or forming bubbles. I've DIYed window film myself and found that even spraying is key—too little and the film sticks too tightly to move, too much foam leaves water stains affecting adhesion. Specialized sprays are more refined but costlier; if you spray the wrong thing like dish soap, excessive foam takes forever to clean and affects film longevity. After application, press firmly to remove bubbles—once the water dries, the film sets in place.
